* Editor: Auto-save on a background goroutine so you don't randomly freeze
the editor up during.
* Fix actor linking issues when you drag and re-place a linked doodad: the
level was too eagerly calling PruneLinks() whenever a doodad was 'destroyed'
(such as the one just picked up) breaking half of the link connection.
* Chunk unloader: do not unload a chunk that has been modified (Set or Delete
called on), keep them in memory until the next ZIP file save to flush them
out to disk.
* Link Tool: if you clicked an actor and don't want to connect a link, click
the first actor again to de-select it.
Updates to the `doodad` tool:
* `doodad edit-level --resize <int>` can re-chunk a level to use a different
chunk size than the default 128. Large chunk sizes 512+ lead to performance
problems.
* The blue bird follows the same base AI as the red bird (it has a
target altitude that it tries to maintain, and it will dive at the
player) but the blue bird flies in a sine wave pattern around its
target altitude. It also has a longer scan radius to search for the
player than the red bird.
* The sine wave pattern of the blue bird means you may fly under its
radar depending how high it is on average.
Cheat codes that replace the player character are refactored to make
it easier to extend, and new cheats have been added:
* super azulian: play as the Red Azulian.
* hyper azulian: play as the White Azulian.
* bluebird: play as the new Bird (blue).
Especially to further optimize memory for large levels, Levels and
Doodads can now read and write to a ZIP file format on disk with
chunks in external files within the zip.
Existing doodads and levels can still load as normal, and will be
converted into ZIP files on the next save:
* The Chunker.ChunkMap which used to hold ALL chunks in the main json/gz
file, now becomes the cache of "hot chunks" loaded from ZIP. If there is
a ZIP file, chunks not accessed recently are flushed from the ChunkMap
to save on memory.
* During save, the ChunkMap is flushed to ZIP along with any non-loaded
chunks from a previous zipfile. So legacy levels "just work" when
saving, and levels loaded FROM Zip will manage their ChunkMap hot
memory more carefully.
Memory savings observed on "Azulian Tag - Forest.level":
* Before: 1716 MB was loaded from the old level format into RAM along
with a slow load screen.
* After: only 243 MB memory was used by the game and it loaded with
a VERY FAST load screen.
Updates to the F3 Debug Overlay:
* "Chunks: 20 in 45 out 20 cached" shows the count of chunks inside the
viewport (having bitmaps and textures loaded) vs. chunks outside which
have their textures freed (but data kept), and the number of chunks
currently hot cached in the ChunkMap.
The `doodad` tool has new commands to "touch" your existing levels
and doodads, to upgrade them to the new format (or you can simply
open and re-save them in-game):
doodad edit-level --touch ./example.level
doodad edit-doodad --touch ./example.doodad
The output from that and `doodad show` should say "File format: zipfile"
in the headers section.
To do:
* File attachments should also go in as ZIP files, e.g. wallpapers
Instead of the loadscreen eager-loading ALL level chunks to Go Images, only
load the chunks within the "LoadingViewport" - which is the on-screen
Viewport plus a margin of chunks off the screen edges.
During gameplay, every few ticks, reevaluate which chunks are inside or
outside the LoadingViewport; for chunks outside, free their SDL2 textures
and free their cached bitmaps to keep overall memory usage down. The
AzulianTag-Forest level now stays under 200 Textures at any given time
and the loadscreen goes faster as it doesn't have to load every chunk's
images up front.
The LoadUnloadChunk feature can be turned on/off with feature flags. If
disabled the old behavior is restored: loadscreen loads all images and
the LoadUnloadChunks function is not run.
Other changes:
* loadscreen: do not free textures in the Hide() function as this runs on
a different goroutine and may break. The 4 wallpaper textures are OK
to keep in memory anyway, the loadscreen is reused often!
* Free more leaked textures: on the Inventory frame and when an actor
calls Self.Destroy()
* Stop leaking goroutines in the PubSub feature of the doodad script
engine; scripting.Supervisor.Teardown() sends a stop signal to all
scripts to clean up neatly. Canvas.Destroy() tears down its scripting
supervisor automatically.
* Added to the F3 Debug Overlay is a "Texture:" label that counts the number
of textures currently loaded by the (SDL2) render engine.
* Added Teardown() functions to Level, Doodad and the Chunker they both use
to free up SDL2 textures for all their cached graphics.
* The Canvas.Destroy() function now cleans up all textures that the Canvas
is responsible for: calling the Teardown() of the Level or Doodad, calling
Destroy() on all level actors, and cleaning up Wallpaper textures.
* The Destroy() method of the game's various Scenes will properly Destroy()
their canvases to clean up when transitioning to another scene. The
MainScene, MenuScene, EditorScene and PlayScene.
* Fix the sprites package to actually cache the ui.Image widgets. The game
has very few sprites so no need to free them just yet.
Some tricky places that were leaking textures have been cleaned up:
* Canvas.InstallActors() destroys the canvases of existing actors before it
reinitializes the list and installs the replacements.
* The DraggableActor when the user is dragging an actor around their level
cleans up the blueprint masked drag/drop actor before nulling it out.
Misc changes:
* The player character cheats during Play Mode will immediately swap out the
player character on the current level.
* Properly call the Close() function instead of Hide() to dismiss popup
windows. The Close() function itself calls Hide() but also triggers
WindowClose event handlers. The Doodad Dropper subscribes to its close
event to free textures for all its doodad canvases.
* Bird is not solid when colliding with other birds.
* If the dev shell is used to run JavaScript during Play Mode, consider
it cheating (so player can't `$ d.Scene.ResetTimer()` for example)
* On Survival Mode levels, DieByFire immediately opens the End Level
(silver score) modal rather than respawn from checkpoint, so levels
don't need checkpoint contraptions to end the level.
* During level loading screens, wait and call doodads' main() function
until the very end.
New features:
* Flood Tool for the editor. It replaces pixels of one color with another,
contiguously. Has limits on how far from the original pixel it will color,
to avoid infinite loops in case the user clicked on wide open void. The
limit when clicking an existing color is 1200px or only a 600px limit if
clicking into the void.
* Cheat code: 'master key' to play locked Story Mode levels.
Level GameRules feature added:
* A new tab in the Level Properties dialog
* Difficulty has been moved to this tab
* Survival Mode: for silver high score, longest time alive is better than
fastest time, for Azulian Tag maps. Gold high score is still based on
fastest time - find the hidden level exit without dying!
Tweaks to the Azulians' jump heights:
* Blue Azulian: 12 -> 14
* Red Azulian: 14 -> 18
* White Azulian: 16 -> 20
Bugs fixed:
* When editing your Palette to rename a color or add a new color, it wasn't
possible to draw with that color until the editor was completely unloaded
and reloaded; this is now fixed.
* Minor bugfix in Difficulty.String() for Peaceful (-1) difficulty to avoid
a negative array index.
* Try and prevent user giving the same name to multiple swatches on their
palette. Replacing the whole palette can let duplication through still.
Added a new level property: Difficulty
* An enum ranging from -1, 0, 1 (Peaceful, Normal, Hard)
* Default difficulty is Normal; pre-existing levels are Normal by
default per the zero value.
Doodad scripts can read the difficulty via the new global variable
`Level.Difficulty` and some doodads have been updated:
* Azulians: on Peaceful they ignore all player characters, and on Hard
they are in "hunt mode": infinite aggro radius and they're aggressive
to all characters.
* Bird: on Peaceful they will not dive and attack any player character.
Other spit and polish:
* New Level/Level Properties UI reworked into a magicform.
* New "PromptPre(question, answer, func)" function for prompting the
user with the developer shell, but pre-filling in an answer for them
to either post or edit.
* magicform has a PromptUser field option for simple Text/Int fields
which present as buttons, so magicform can prompt and update the
variable itself.
* Don't show the _autosave.doodad in the Doodad Dropper window.
UI improvements specifically for mobile (running the game with the
`-w mobile` or `-w landscape` options) screen sizes.
* Rework the Settings window to be mobile friendly to landscape
oriented screens (`doodle -w landscape`) and migrate Options tab
to magicform.
* The toolbar in the Editor will be a single column of buttons
on small screens, such as `-w mobile` (375x812) portrait mode
smartphone. On larger screens the toolbar shows in two columns
of buttons.
* Fix tooltips not drawing on top.
* Centralize the hard-coded references to specific font filenames
* Add cheat code: `test load screen` to bring a sample loading screen up
for a few seconds. It needs improvement on `-w landscape`
Two new tools added to the Level Editor:
* Pan Tool: left-click to scroll the level around safely.
* Text Tool: write text onto your level.
Features of the Text Tool:
* Can choose from the game's built-in fonts, size and enter the message
you want to write.
* The mouse cursor previews the text when hovered over the level.
* Click to "stamp" the text onto your level. The currently selected
color swatch will be used to color the text in.
* Adds two new fonts: Azulian.ttf and Rive.ttf that can be selected in
the Text Tool.
Some implementation notes:
* Added package native/engine_sdl.go that handles the lower-level
SDL2_TTF logic to rasterize the text into a black&white image.
* WASM not supported yet (if the game even still built for WASM);
native/engine_wasm.go stubs out the TextToImage() call with a "not
supported" error just in case.
Other changes:
* New Toolbar icons: they are 24x24 instead of 32x32 to make more room
for more tools.
* The toolbar now shows two buttons per row for a more densely packed
layout. For very narrow screen widths (< 600px) the default Vertical
Toolbar layout will use one-button-per-row to not eat too much screen
real estate.
* In the Horizontal Toolbars layout there are 2 buttons per column.
* Add methods `Invulnerable() bool` and `SetInvulnerable(bool)` to the
Actor API accessible in JavaScript (e.g. `Self.SetInvulnerable(true)`)
* The Anvil is invulnerable - when played as, it can crush other mobs by
jumping on them but is not defeated by those mobs at the same time.
* Anvils don't destroy invulnerable mobs, such as other Anvils.
* Bugfix: the Electric Door is considered to be opened from the first
frame of animation when the door begins opening, and remains opened
until the final frame of animation when it is closing.
* New cheat code: `megaton weight` to play as the Anvil by default.
Adds support for Xbox and Nintendo style game controllers. The gamepad
controls are documented on the README and in the game's Settings window.
The buttons are not customizable yet, except that the player can choose
between two button styles:
* X Style (default): "A" button is on the bottom and "B" on the right.
* N Style: swaps the A/B and the X/Y buttons to use a Nintendo-style
layout instead of an Xbox-style.
Link a Doodad to a Checkpoint Flag (like you would a Start Flag) and
crossing the flag will replace the player with that doodad. Multiple
checkpoint flags like this can toggle you between characters.
* Azulians are now friendly to player characters who have the word
"Azulian" in their title.
* Improve Bird as the playable character:
* Dive animation if the player flies diagonally downwards
* Animation loop while hovering in the air instead of pausing
* Checkpoint flags don't spam each other on PubSub so much which could
sometimes lead to deadlocks!
SetPlayerCharacter added to the JavaScript API. The Checkpoint Flag
(not the region) can link to a doodad and replace the player character
with that linked doodad when you activate the checkpoint:
Actors.SetPlayerCharacter(filename string): like "boy.doodad"
Add various panic catchers to make JavaScript safer and log issues
to console.
New functions are available on the JavaScript API for doodads:
* Actors.At(Point) []*Actor: returns actors intersecting a point
* Actors.FindPlayer() *Actor: returns the nearest player character
* Actors.New(filename string): create a new actor (NOT TESTED YET!)
* Self.Grounded() bool: query the grounded status of current actor
With this the game's built-in doodads have been revised:
* Bird: will now scan 240 pixels diagonally searching for the player
character and will dive if seen. The Bird is dangerous while
diving. It will return to its original altitude once it touches
the ground.
* Azulians: the Azulians are now dangerous to player characters but
not to the Thief. Azulians will begin to follow the player when
they are within the aggro range and will hop if the player is
above them to try and overcome obstacles.
* Blue Azulian: aggro is (250, 100) jump speed 12 movement 2
* Red Azulian: aggro is (250, 200) jump speed 14 movement 4
* magicform is a helper package that may eventually be part of the go/ui
library, for easily creating structured form layouts.
* The Level Publisher UI is the first to utilize magicform.
Refactor how level publishing works:
* Level data now stores SaveDoodads and SaveBuiltins (bools) and when
the level editor saves the file, it will attach custom and/or builtin
doodads just before save.
* Move the menu item from the File menu to Level->Publish
* The Publisher UI just shows the checkboxes to toggle the level
settings and a convenient Save button along with descriptive text.
* Free versions get the "Register" window popping up if they click the
Save Now button from within the publisher window.
Note: free versions can still toggle the booleans on/off but their game
will not attach any new doodads on save.
* Free games which open a level w/ embedded doodads will get a pop-up
warning that the doodads aren't available.
* If they DON'T turn off the SaveDoodads option, they can still edit and
save the level and keep the existing doodads attached.
* If they UNCHECK the option and save, all attached doodads are removed
from the level.
* Switch from otto to goja for JavaScript engine.
* goja supports many ES6 syntax features like arrow functions,
const/let, for-of with more coming soon.
* Same great features as otto, more modern environment for doodads!
* Clean up unused msgpack code for levels and doodads
* Fix the cosmetic bug where actors in your level would display wrongly
when scrolling off the top/left edges of the screen: they used to
anchor at their own 0,0 coordinate and crop their width/height leading
to a 'scrolling' effect that didn't happen on the right/bottom edges.
* The Red Bird now records its original altitude on the level and will
try and return there should it accidentally climb up or down a wall.
Sometimes goes into a wavy pattern surrounding its original altitude.
* Editor UI: in the default (vertical) toolbar, the Palette now has a
two column view to show more color choices on screen at once.
* User setting added: hide the touch control hints.
* The level scroll logic was getting a null pointer crash if you open a
doodad rather than a level file.
* Add a crosshair option to the level editor, configurable in the Game
Settings window.
- Fix a memory sharing bug in the Giant Screenshot feature.
- Main Menu to eagerload chunks in the background to make scrolling less
jittery. No time for a loadscreen!
- Extra script debugging: names/IDs of doodads are shown when they send
messages to one another.
- Level Properties: you can edit the Bounded max width/height values for
the level.
Doodad changes:
- Buttons: fix a timing bug and keep better track of who is stepping on it,
only popping up when all colliders have left. The effect: they pop up
immediately (not after 200ms) and are more reliable.
- Keys: zero-qty keys will no longer put themselves into the inventory of
characters who already have one except for the player character. So
the Thief will not steal them if she already has the key.
Added to the JavaScript API:
* time.Hour, time.Minute, time.Second, time.Millisecond, time.Microsecond
* Tweak max gravity speed to match player max velocity.
* Boy's script watches for his velocity to flip suddenly and stops
animations, limiting the moonwalking a bit.
* JS API: Self.GetVelocity() added.
Add multi-touch gesture support so that the player can scroll the level
in the editor (and title screen) by treating a two finger swipe to be
equivalent to a middle click drag.
Fun quirks found with SDL2's MultiGestureEvent:
* They don't begin sending us the event until motion is detected after
two fingers have touched the screen; not the moment the second finger
touches it.
* It spams us with events when it detects any tiny change and a lot of
cool details like rotate/pinch deltas, but it never tells us when the
multitouch STOPS! The game has to block left clicks while multitouch
happens so the user doesn't draw all over their level, so it needs to
know when touch has ended.
* The workaround is to track the mouse cursor position at the first
touch and each delta thereafter; if the deltas stop changing tick to
tick, unset the "is touching" variable.
In the editor, clicking and dragging with the middle mouse button
will scroll the view of the editor in place of the arrow keys.
When entering Play Mode, the original scroll position in the level
editor is remembered for when you come back - no more having to
scroll from 0,0 each time to get back to where you were working!
New category for the Doodad Dropper: "Technical"
Technical doodads have a dashed outline and label for now, and they
turn invisible on level start, and are for hidden technical effects on
your level.
The doodads include:
* Goal Region: acts like an invisible Exit Flag (128x128), the level is
won when the player character touches this region.
* Fire Region: acts like a death barrier (128x128), kills the player
when a generic "You have died!" message.
* Power Source: on level start, acts like a switch and emits a
power(true) signal to all linked doodads. Link it to your Electric
Door for it to be open by default in your level!
* Stall Player (250ms): The player is paused for a moment the first time
it touches this region. Useful to work around timing issues, e.g.
help prevent the player from winning a race against another character.
There are some UI improvements to the Doodad Dropper window:
* If the first page of doodads is short, extra spacers are added so the
alignment and size shows correctly.
* Added a 'background pattern' to the window: any unoccupied icon space
has an inset rectangle slot.
* "Last pages" which are short still render weirdly without reserving
the correct height in the TabFrame.
Doodad scripting engine updates:
* Self.Hide() and Self.Show() available.
* Subscribe to "broadcast:ready" to know when the level is ready, so you
can safely Publish messages without deadlocks!
For levels having a top/left scroll boundary, the top/left point takes
higher priority for resolving out-of-bounds scroll ranges instead of the
bottom/right.
This fixes a bug where you Zoom Out of a level far enough that the
entire boundaries of a Bounded level are smaller than the viewport into
the level. It could happen if playing normal levels in Play Mode on a
very high-resolution monitor. Previously, the level would anchor to the
bottom/right corner of your screen.
With the Zoom In/Out Feature this broke the ability to scroll well on
the level; so the easy fix is to put the X>0, Y>0 bounds check after the
above, so the level will hug the top/left corner of the screen which
fixes both problems.
* If you open a wide unbounded level like Castle.level and zoom out and
scroll left (into negative world coordinates), the level chunks
display correctly now.
* Doodad outline while dragging is now sized properly for the zoom level
* Make doodad hitboxes for Actor/Link Tool more accurate while zoomed
* Fix chunks low on the level not loading while zoomed in
* Fix Link lines drawn between doodads while zoomed - they point to the
correct position and their DrawLine calls have been optimized so they
don't lag out the level when lots of them are drawn at once.
* When the Actor Tool or Link Tool is active, mouse-over hitboxes on the
level's actors now works correctly while zoomed and scrolling in the
level.
* Regression: Level chunks don't appear outside a certain range from
origin while zoomed in.
* Regression: Actors don't draw their sprite while zoomed in, but do
when zoomed out.
Improvements to the Zoom feature:
* Actor position and size within your level scales up and down
appropriately. The canvas size of the actor is scaled and its canvas
is told the Zoom number of the parent so it will render its own
graphic scaled correctly too.
Other features:
* "Experimental" tab added to the Settings window as a UI version of the
--experimental CLI option. The option saves persistently to disk.
* The "Replace Palette" experimental feature now works better. Debating
whether it's a useful feature to even have.
Progress on the Zoom feature: when you zoom in and out, you can draw
shapes accurately onto the level. Seems a little buggy if you edit
while scrolling (as in drawing a very long line).
The title screen buttons are now more colorful.
A new property is added to the Doodad struct: Hitbox (Rect).
The uix.Actor for Play Mode will defer to the Doodad.Hitbox until the
JavaScript has manually set its own via Self.SetHitbox(). So in effect,
scripts no longer need to worry about their hitbox! The one assigned to
the Doodad will be the default.
Scripts can check if their hitbox is zero before setting a default:
if (Self.Hitbox().IsZero()) {
var size = Self.Size() // get doodad canvas size
Self.SetHitbox(0, 0, size, size) // the full square
}
The built-in generic doodad scripts have made this change, so that your
simple doodad can have a custom hitbox defined easily using in-game
tools.
Other changes:
* New script: Generic Collectible Item. Selecting it will add a
"quantity" tag to your doodad, to easily configure the script.
* JavaScript API: "Self.Hitbox()" returns your doodad's current hitbox.
You can check "Self.Hitbox.IsZero()" to check if it's empty.
In the Doodad Properties window, instead of browsing to select a .js
file to install your script, a SelectBox of built-in generic scripts are
available. These scripts implement simple behaviors and adapt to the
full canvas size of the doodad.
Built-in scripts so far include:
* generic-anvil.js: behaves just like the Anvil.
* generic-fire.js: the entire canvas hitbox acts like fire pixels,
"burning" mobile doodads and failing the level for the player.
* generic-solid.js: the entire canvas hitbox acts solid
* New Doodad: Checkpoint Flag. They update the player's spawn point
whenever the player passes one. The most recently activated
checkpoint is rendered brighter than the others.
* End Level Modal: the fake alert box window drawn by the Play Mode
is replaced with a fancy modal widget (similar to Alert and Confirm).
It handles level victory or failure conditions and can show or hide
all the buttons as needed.
* Gameplay: There is a "Retry from Checkpoint" option added, which
appears in the level failure modal. It will teleport you back to
the Start Flag or the last Checkpoint Flag you had touched, without
resetting the level -- your keys, unlocked doors, etc. will be
preserved so you can retry.
* Set a maximum speed on the "Camera Follows Actor" logic of 64
pixels per tick. This results in a smoother scrolling transition
when the player jumps to a new location on the map, such as by
a Warp Door.
* Update the default color palettes:
* All: Add a "hint" magenta color.
* Colored Pencil: Add a "darkstone" solid color.
Updates to the Doodads JavaScript API:
* SetCheckpoint(Point(x, y)): set the player character's spawn
position. Giving it Self.Position() is an easy way to set the
player spawn to your doodad's location.
New feature: link a Start Flag to another doodad in your level
and you will play as that doodad instead of Boy. All Creatures
are designed to be playable. Playing as "other" doodads leads
to interesting effects, like not being able to activate buttons,
switches, or warp doors and not having an inventory to pick up
keys. The Anvil is fun: it can destroy other mobile doodads by
jumping on them.
If the actor does not specify that it has gravity, the gameplay
starts in antigravity mode. This will be the vast majority of
non-mobile doodads and the Bird.
Other changes:
* The Blue and Red Azulians now share a doodad script.
* The Azulians AI is still to walk back and forth, pickup keys and
press buttons. The Blue Azulian walks slower than the red one.
* The Blue Azulian is no longer hidden from the doodads list.
* Actor UUID values in levels are now V1 UUIDs (time-ordered).
This will help to reliably resolve conflicts in draw order
of overlapping doodads (newest added to level wins).
* Link Tool: clicking on a pair of already-linked doodads will
now unlink them, so you don't have to delete one to delete
the link.
* Actor Tool: deleting an actor immediately calls PruneLinks()
to clean up any links that the deleted doodad might have.
This commit adds the Thief character with starter graphics
(no animations).
The Thief walks back and forth and will steal items from other
doodads, including the player. For singleton items that have no
quantity, like the Colored Keys, the Thief will only steal one
if he does not already have it. Quantitied items like the
Small Key are always stolen.
Flexibility in the playable character is introduced: Boy,
Azulian, Bird, and Thief all respond to playable controls.
There is not currently a method to enable these apart from
modifying balance.PlayerCharacterDoodad at compile time.
New and Changed Doodads
* Thief: new doodad that walks back and forth and will steal
items from other characters inventory.
* Bird: has no inventory and cannot pick up items, unless player
controlled. Its hitbox has also been fixed so it collides with
floors correctly - not something normally seen in the Bird.
* Boy: opts in to have inventory.
* Keys (all): only gives themselves to actors having inventories.
JavaScript API - New functions available
* Self.IsPlayer() - returns if the current actor IS the player.
* Self.SetInventory(bool) - doodads must opt-in to having an
inventory. Keys should only give themselves to doodads having
an inventory.
* Self.HasInventory() bool
* Self.AddItem(filename, qty)
* Self.RemoveItem(filename, qty)
* Self.HasItem(filename)
* Self.Inventory() - returns map[string]int
* Self.ClearInventory()
* Self.OnLeave(func(e)) now receives a CollideEvent as parameter
instead of the useless actor ID. Notably, e.Actor is the
leaving actor and e.Settled is always true.
Other Changes
* Play Mode: if playing as a character which doesn't obey gravity,
such as the bird, antigravity controls are enabled by default.
If you `import antigravity` you can turn gravity back on.
* Doodad collision scripts are no longer run in parallel
goroutines. It made the Thief's job difficult trying to steal
items in many threads simultaneously!
* The Anvil doodad is affected by gravity and becomes dangerous when
falling. If it lands on the player character, you die! If it lands on
any other mobile doodad, it destroys it! It can land on solid doodads
such as the Electric Trapdoor and the Crumbly Floor. It will activate
a Crumbly Floor if it lands on one, and can activate buttons and
switches that it passes.
* JavaScript API: FailLevel(message) can be called from a doodad to kill
the player character. The Anvil does this if it collides with the
player while it's been falling.
* New doodad: Electric Trapdoor. It is a horizontal version of the
Electric Door. Opens while powered by a button or a switch and closes
when it loses power.
* The Box doodad will reset to its original location if it receives a
power signal from a linked Button or Switch. So for box pushing
puzzles you can add a reset button in case the boxes get stuck.
* Refactored the Doodad build scripts into many Makefiles for easier
iteration (don't need to compile ALL doodads to test one).
Updates to the JavaScript API for doodads:
* Self.MoveTo(Point) is now available to set the actor's position in
world coordinates.
* The loading screen for Edit and Play modes is stable and the risk of
game crash is removed. The root cause was the setupAsync() functions
running on a background goroutine, and running SDL2 draw functions
while NOT on the main thread, which causes problems.
* The fix is all SDL2 Texture draws become lazy loaded: when the main
thread is presenting, any Wallpaper or ui.Image that has no texture
yet gets one created at that time from the cached image.Image.
* All internal game logic then uses image.Image types, to cache bitmaps
of Level Chunks, Wallpaper images, Sprite icons, etc. and the game is
free to prepare these asynchronously; only the main thread ever
Presents and the SDL2 textures initialize on first appearance.
* Several functions had arguments cleaned up: Canvas.LoadLevel() does
not need the render.Engine as (e.g. wallpaper) textures don't render
at that stage.
* Holding Shift while pressing arrow keys in the editor will scroll by
just 1 pixel per tick to aid in precise debugging with the Zoom In/Out
feature.
* The keybinds used in canvas_editable.go to catch the arrow keys are
updated to use our nice keybind package. As a consequence, the WASD
keys will also scroll the level.
* The "d for Doodads" keybind is renamed "q" so as not to open the
Doodads window whenever scrolling right using the WASD keys.
WorldIndexAt() translates the pixel below the mouse cursor in screen
space (0,0 at top-left corner of the application window) into a world
coordinate in the level shown inside the canvas, taking into account the
canvas's position on the window and the scroll position.
It now translates correctly when zoom In or Out, so the "Abs:" mouse
position level in the status bar shows correctly.
Zoom features that are still jank:
- Scrolling while zoomed in, the chunks to the top/left start unloading
too rapidly and outpacing the scroll, eventually level is invisible
- Drawing and committing pixels to the image while zoomed in/out is
unpredictable where the pixels actually land.
- Actors in the level don't move or zoom at all.
* Got the level chunks AND the wallpaper to both scale UP and DOWN
consistently together.
* Trying to draw new pixels while zoomed in/out ends up offsetting the
pixels by 2X still. Still seems an issue between screen coordinates
and world coordinates. Zoom in 2X and try and draw a line 64px from
the corners of the screen? The committed line appropriately lands at
the 64px coord on the level data but, zoomed in, it appears 2X to the
right on the screen from where I dropped the cursor!
* When zooming OUT, the limit on number of chunks the viewport will try
and render is not increased, leaving dead space in the screen; more
chunks should render when there's room.
* Instead of a simple "cur. ver != latest ver" check, parse the Major,
Minor and Patch components and do a detailed check.
* So a x.x.1 release could be made for a specific platform that had a
bad build, and it won't mind when it sees the latest version is the
older x.x.0 build that other platforms had working fine.
* Free (shareware) versions of the game will not be able to Publish
Levels (attach custom doodads to the level file) and they will not be
able to load a level which relies on embedded doodads.
* The UI for the Publish Level window is still available, but clicking
on the confirm button will just open the Register (License) window.
* When loading a level containing embedded doodads: if some can't load
because they're embedded and you're using the free version of the
game, the error message is customized to reflect that.
* The scrollbox by which the game follows the player character has been
revised, it is now an offset away from the window's center instead of
fixed pixel distances from the window's edges.
* Mobile form-factor (Pinephone) now scrolls OK instead of jerking back
and forth rapidly when moving left.
* The Publisher is all hooked up. No native Save File dialogs yet, so
uses the dev shell Prompt() to ask for output filename.
* Custom-only or builtin doodads too can be stored in the level's file
data, at "assets/doodads/*.doodad"
* When loading the embedded level in the Editor: it gets its custom
doodads out of its file, and you can drag and drop them elsehwere,
link them, Play Mode can use them, etc. but they won't appear in the
Doodad Dropper if they are not installed in your local doodads
directory.
* Fleshed out serialization API for the Doodad files:
- LoadFromEmbeddable() looks to load a doodad from embeddable file
data in addition to the usual places.
- Serialize() returns the doodad in bytes, for easy access to embed
into level data.
- Deserialize() to parse and return from bytes.
* When loading a level that references doodads not found in its embedded
data or the filesystem: an Alert modal appears listing the missing
doodads. The rest of the level loads fine, but the actors referenced
by these doodads don't load.
Palette swatches gain a new property: Pattern.
Patterns are grayscale textures that the swatch color will sample
against when drawing pixels to the level, by taking the world coordinate
modulo a value inside the texture.
A few algorithms were tried (Screen, Overlay), this branch lands on one
that tries to cast the color from grayscale which comes out rather dark;
to get a patterned color to look black while still seeing the pattern,
the color needs to be as bright as #777 to get the effect.
