Updates the savegame.json file format:
* Levels now have a UUID value assigned at first save.
* The savegame.json will now track level completion/score based on UUID,
making it robust to filename changes in either levels or levelpacks.
* The savegame file is auto-migrated on startup - for any levels not
found or have no UUID, no change is made, it's backwards compatible.
* Level Properties window adds an "Advanced" tab to show/re-roll UUID.
New JavaScript API for doodad scripts:
* `Actors.CameraFollowPlayer()` tells the camera to return focus to the
player character. Useful for "cutscene" doodads that freeze the player,
call `Self.CameraFollowMe()` and do a thing before unfreezing and sending the
camera back to the player. (Or it will follow them at their next directional
input control).
* `Self.MoveBy(Point(x, y int))` to move the current actor a bit.
New option for the `doodad` command-line tool:
* `doodad resave <.level or .doodad>` will load and re-save a drawing, to
migrate it to the newest file format versions.
Small tweaks:
* On bounded levels, allow the camera to still follow the player if the player
finds themselves WELL far out of bounds (40 pixels margin). So on bounded
levels you can create "interior rooms" out-of-bounds to Warp Door into.
* New wallpaper: "Atmosphere" has a black starscape pattern that fades into a
solid blue atmosphere.
* Camera strictly follows the player the first 20 ticks, not 60 of level start
* If player is frozen, directional inputs do not take the camera focus back.
* New script API method: Self.CameraFollowMe() to draw camera focus toward
your doodad (it sets the Canvas.FollowActor target.)
* The camera will go back to following the player on any action inputs
(arrow keys, jump, use, etc.); if the player is constantly on the move
the camera stays on him even if another actor is trying to take the focus.
* The first few ticks of Play Mode the player character is always followed,
to allow for Anvils to settle into place without taking the focus.
* Canvas FollowActor: if the actor is 4 times the max scroll speed away,
allow scrolling in greater leaps of 4 times the max scroll speed.
New and Changed Doodads
* Anvils will take the camera focus while they are falling.
* New doodad: "Look At Me" - a 'camera region' technical doodad. Link it to
any power source such as a Button - when this doodad receives power it will
take the camera focus for a few frames. Use it to highlight a door that
opened far off screen by linking the Button to both an Electric Door and
a "Look At Me" near the door.
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.
* 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
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!
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.
* 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.
* 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.
* 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.
* You can now browse for a custom wallpaper image to use with your
levels. A platform-native file picker dialog is used (no WASM support)
* In the New/Edit Level Properties dialog, the Wallpaper drop-down
includes an option to browse for a custom map.
* When editing an existing level: the wallpaper takes effect immediately
in your level once the file is picked. For NEW levels, the wallpaper
will appear once the "Continue" button is pressed.
* All common image types supported: png, jpeg, gif.
* The wallpaper is embedded in the level using the filepath
"assets/wallpapers/custom.b64img" as a Base64-encoded blob of the
image data.
* The `doodad show` command will list the names and sizes of files
embedded in levels. `doodad show --attachment <name>` will get an
attachment and print it to the console window.
* To extract a wallpaper image from a level:
`doodad show -a assets/wallpapers/custom.b64img | base64 -d > out.png`
* Fix the level collision bug that allowed clipping thru a ceiling while
climbing up a wall.
* Fix the scrolling behavior to keep the character on-screen no matter
how fast the character is moving, especially downwards.
* Increase player speed and gravity.
* New cheat: "ghost mode" disables clipping for the player character.
* Mark an actor as "grounded" if they fall and are stopped by the lower
level border, so they may jump again.
* Debug mode: no longer enables the DebugOverlay (F3) by default, but
does now insert the current FPS counter into the window title bar.
* ui.Frame: set a default "mostly transparent" BG color so the frame
background doesn't render as white.
* Add the MenuScene which will house the game's main menus.
* The "New Level" menu is first to be added.
* UI lets you pick Page Type and Wallpaper using radio buttons.
* Page Type: Unbounded, Bounded (default), No Negative Space, Bordered
* Fix bugs in uix.Canvas to fully support all these page types.
Fixes:
* Move the call to CollidesWithGrid() inside the Canvas instead of
outside in the PlayScene.movePlayer() so it can apply to all Actors
in motion.
* PlayScene.movePlayer() in turn just sets the player's Velocity so the
Canvas.Loop() can move the actor itself.
* When keeping the player inside the level boundaries: previously it was
assuming the player Position was relative to the window, and was
checking the WorldIndexAt and getting wrong results.
* Canvas scrolling (loopFollowActor): check that the actor is getting
close to the screen edge using the Viewport into the world, NOT the
screen-relative coordinates of the Canvas bounding boxes.
