Fix collision detection when an actor's hitbox is offset from 0,0:
* Actors having a hitbox that didn't begin at X,Y 0,0 used to experience
clipping issues with level geometry: because the game tracks their Position
(top left corner of their graphical sprite) and their target position wasn't
being correctly offset by their hitbox offset.
* To resolve the issue, an "ActorOffset" struct is added: you give it the
original game's Actor (with its offset hitbox) and it will record the offset
and give a mocked Actor for collision detection purposes: where the Position
and Target can be offset and where its Hitbox claims to begin at 0,0 matching
its offsetted Position.
* The translation between your original Actor and Offset Actor is handled at the
boundary of the CollidesWithGrid function, so the main algorithm didn't need
to be messed with and the game itself doesn't need to care about the offset.
Make some fixes to the doodad CLI tool:
* Fix palette colors being duplicated/doubled when converting from an image.
* The --palette flag in `doodad convert` now actually functions: so you can
supply an initial palette.json with colors and attributes to e.g. mark which
colors should be solid or fire and give them names. The palette.json doesn't
need to be comprehensive: it will be extended with new distinct colors as
needed during the conversion.
* For the doodad tool: skip the assets embed folder, the doodad binary doesn't
need to include all the game's doodads/levelpacks/etc. and can save on file
size.
* In `doodad resave`, .doodad files with Vacuum() and upgrade their chunker from
the MapAccessor to the RLEAccessor.
* Fix a rare concurrent map read/write error in OptimizeChunkerAccessors.
Levels can now be converted to RLE encoded chunk accessors and be re-saved
continuously without any loss of information.
Off-by-one errors resolved:
* The rle.NewGrid() was adding a +1 everywhere making the 2D grids have 129
elements to a side for a 128 chunk size.
* In rle.Decompress() the cursor value and translation to X,Y coordinates is
fixed to avoid a pixel going missing at the end of the first row (128,0)
* The abs.X-- hack in UnmarshalBinary is no longer needed to prevent the
chunks from scooting a pixel to the right on every save.
Doodad tool updates:
* Remove unused CLI flags in `doodad resave` (actors, chunks, script,
attachment, verbose) and add a `--output` flag to save to a different file
name to the original.
* Update `doodad show` to allow debugging of RLE compressed chunks:
* CLI flag `--chunk=1,2` to specify a single chunk coordinate to debug
* CLI flag `--visualize-rle` will Visualize() RLE compressed chunks in
their 2D grid form in your terminal window (VERY noisy for large
levels! Use the --chunk option to narrow to one chunk).
Bug fixes and misc changes:
* Chunk.Usage() to return a better percentage of chunk utilization.
* Chunker.ChunkFromZipfile() was split out into two functions:
* RawChunkFromZipfile retrieves the raw bytes of the chunk as well as the
file extension discovered (.bin or .json) so the caller can interpret
the bytes correctly.
* ChunkFromZipfile calls the former function and then depending on file
extension, unmarshals from binary or json.
* The Raw function enables the `doodad show` command to debug and visualize
the raw contents of the RLE compressed chunks.
* Updated the Visualize() function for the RLE encoder: instead of converting
palette indexes to hex (0-F) which would begin causing problems for palette
indexes above 16 (as they would use two+ characters), indexes are mapped to
a wider range of symbols (0-9A-Z) and roll over if you have more than 36
colors on your level. This at least keeps the Visualize() grid an easy to
read 128x128 characters in your terminal.
* Update native.DefaultAuthor to get the name registered from the user's JWT
license in a way that avoids cyclic dependency errors.
* When plus_dpp.go#GetRegistration succeeds, it updates DefaultAuthor to the
registered name. The main.go now gets and prints the registered owner to
ensure this is populated on startup.
* Return correct ErrRegisteredFeature error when the FOSS version fails
to load embedded doodads.
* pkg/plus/dpp is the main plugin bridge, and defines nothing but an interface
that defines the Doodle++ surface area (referring to internal game types such
as doodad.Doodad or level.Level), but not their implementations.
* dpp.Driver (an interface) is the main API that other parts of the game will
call, for example "dpp.Driver.IsLevelSigned()"
* plus_dpp.go and plus_foss.go provide the dpp.Driver implementation for their
build; with plus_dpp.go generally forwarding function calls directly to the
proprietary dpp package and plus_foss.go generally returning false/errors.
* The bootstrap package simply assigns the above stub function to dpp.Driver
* pkg/plus/bootstrap is a package directly imported by main (in the doodle and
doodad programs) and it works around circular dependency issues: this package
simply assigns dpp.Driver to the DPP or FOSS version.
Miscellaneous fixes:
* File->Open in the editor and PlayScene will use the new Open Level window
instead of loading the legacy GotoLoadMenu scene.
* Deprecated legacy scenes: d.GotoLoadMenu() and d.GotoPlayMenu().
* The doodle-admin program depends on the private dpp package, so can not be
compiled in FOSS mode.
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.
Add the ability for the free version of the game to allow loading levels that
use embedded custom doodads if those levels are signed.
* Uses the same signing keys as the JWT token for license registrations.
* Levels and Levelpacks can both be signed. So individual levels with embedded
doodads can work in free versions of the game.
* Levelpacks now support embedded doodads properly: the individual levels in
the pack don't need to embed a custom doodad, but if the doodad exists in
the levelpack's doodads/ folder it will load from there instead - for full
versions of the game OR when the levelpack is signed.
Signatures are computed by getting a listing of embedded assets inside the
zipfile (the assets/ folder in levels, and the doodads/ + levels/ folders
in levelpacks). Thus for individual signed levels, the level geometry and
metadata may be changed without breaking the signature but if custom doodads
are changed the signature will break.
The doodle-admin command adds subcommands to `sign-level` and `verify-level`
to manage signatures on levels and levelpacks.
When using the `doodad levelpack create` command, any custom doodads the
levels mention that are found in your profile directory get embedded into
the zipfile by default (with --doodads custom).
* Fix display bug with rectangular doodads scrolling off screen.
* The default Author of new files will be your registration name, if available
before using your $USER name.
Convert the Chunker size to a uint8 so chunk sizes are limited to 255px. This
means that inside of a chunk, uint8's can track the relative pixel coordinates
and result in a great memory savings since all of these uint8's are currently
64-bits wide apiece.
WIP on rectangular shaped doodads:
* You can create such a doodad in the editor and draw it normally.
* It doesn't draw the right size when dragged into your level however:
- In uix.Actor.Size() it gets a rect of the doodad's square Chunker size,
instead of getting the proper doodad.Size rect.
- If you give it the doodad.Size rect, it draws the Canvas size correctly
instead of a square - the full drawing appears and in gameplay its hitbox
(assuming the same large rectangle size) works correctly in-game.
- But, the doodad has scrolling issues when it gets to the top or left edge
of the screen! This old gnarly bug has come back. For some reason square
canvas doodads draw correctly but rectangular ones have the drawing scroll
just a bit - how far it scrolls is proportional to how big the doodad is,
with the Start Flag only scrolling a few pixels before it stops.
* Add "Options" support for Doodads: these allow for individual Actor instances
on your level to customize properties about the doodad. They're like "Tags"
except the player can customize them on a per-actor basis.
* Doodad Editor: you can specify the Options in the Doodad Properties window.
* Level Editor: when the Actor Tool is selected, on mouse-over of an actor,
clicking on the gear icon will open a new "Actor Properties" window which
shows metadata (title, author, ID, position) and an Options tab to configure
the actor's options.
Updates to the scripting API:
* Self.Options() returns a list of option names defined on the Doodad.
* Self.GetOption(name) returns the value for the named option, or nil if
neither the actor nor its doodad have the option defined. The return type
will be correctly a string, boolean or integer type.
Updates to the doodad command-line tool:
* `doodad show` will print the Options on a .doodad file and, when showing a
.level file with --actors, prints any customized Options with the actors.
* `doodad edit-doodad` adds a --option parameter to define options.
Options added to the game's built-in doodads:
* Warp Doors: "locked (exit only)" will make it so the door can not be opened
by the player, giving the "locked" message (as if it had no linked door),
but the player may still exit from the door if sent by another warp door.
* Electric Door & Electric Trapdoor: "opened" can make the door be opened by
default when the level begins instead of closed. A switch or a button that
removes power will close the door as normal.
* Colored Doors & Small Key Door: "unlocked" will make the door unlocked at
level start, not requiring a key to open it.
* Colored Keys & Small Key: "has gravity" will make the key subject to gravity
and set its Mobile flag so that if it falls onto a button, it will activate.
* Gemstones: they had gravity by default; you can now uncheck "has gravity" to
remove their Gravity and IsMobile status.
* Gemstone Totems: "has gemstone" will set the totem to its unlocked status by
default with the gemstone inserted. No power signal will be emitted; it is
cosmetic only.
* Fire Region: "name" can let you set a name for the fire region similarly to
names for fire pixels: "Watch out for ${name}!"
* Invisible Warp Door: "locked (exit only)" added as well.
* New built-in wallpaper: "Dotted paper (dark)" is a dark-themed wallpaper.
* New built-in palette: "Neon Bright" with bright colors for dark levels.
* New cheat: "warp whistle" to automatically win the level.
* In case the user has a VERY LARGE screen resolution bigger than the full
bounds of a Bounded level, the Play Scene will cap the size and center
the level canvas onto the window. This is preferable to being able to see
beyond the level's boundaries and hitting an invisible wall in-game.
* Make the titlescreen Lazy Scroll work on unbounded levels. It can't bounce
off scroll boundaries but it will reverse course if it reaches the level's
furthest limits.
* Bugfix: characters' white eyes were transparent in-game. Multiple culprits
from the `doodad convert` tool defaulting the chroma key to white, to the
SDL2 textures considering white to be transparent. For the latter, the game
offsets the color by -1 blue.
* 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.
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
Adds `doodad levelpack create` and `doodad levelpack show` commands to
the CLI tool to create levelpacks.
A levelpack is a ZIP file containing a descriptive index.json and
directories for levels and doodads.
* Recolor some of the region doodads
* Add command: `doodad edit-level --remove-actor` to remove actors from
your level.
* Tweak the player jump velocity from playtesting levels.
* Added a Settings window for game options, such as enabling the
horizontal toolbars in Edit Mode. The Settings window also has a
Controls tab showing the gameplay buttons and keyboard shortcuts.
* The Settings window is available as a button on the home screen OR
from the Edit->Settings menu in the EditScene.
* Bugfix: using WASD to move the player character now works better and
is considered by the game to be identical to the arrow key inputs. Boy
now updates his animation based on these keys, and they register as
boolean on/off keys instead of affected by key-repeat.
* Refactor the boolProps: they are all part of usercfg now, and if you
run e.g. "boolProp show-all-doodads true" and then cause the user
settings to save to disk, that boolProp will be permanently enabled
until turned off again.
* New command-line tool: doodle-admin for signing license keys for
users. Includes functions to initialize a keypair, sign license keys
and validate existing keys.
* The Main Menu screen shows a blue "Register Game" button in the bottom
right corner of the screen, for unregistered users only.
* In Edit Mode, there is a "Help -> Register" menu item that opens the
License Window.
* The License UI Window lets the user select the license.key file to
register the game with. If registered, a copy of the key is placed in
Doodle's profile directory and the licensee name/email is shown in the
License UI window.
* Unregistered games will show the word "(shareware)" next to the title
screen version number and Edit Mode status bar.
* No restrictions are yet placed on free versions of the game.
* 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`
* Tightens up the surface area of API methods available to the
JavaScript VMs for doodads. Variables and functions are carefully
passed in one-by-one so the doodad script can only access intended
functions and not snoop on undocumented APIs.
* Wrote tons of user documentation for Doodad Scripts: documented the
full surface area of the exposed JavaScript API now that the surface
area is known and limited.
* Early WIP code for the Campaign JSON
* The `doodad edit-doodad` command now allows setting custom key/value
tags in doodad files, for extra data storage useful to their scripts.
* Colored keys and doors now store a `color` tag with the appropriate
color so that their scripts don't have to parse their Title to find
that information.
* Trapdoors now store a `direction` tag to hold the direction the door
is facing.
Add new doodads:
* Start Flag: place this in a level to set the spawn point of the player
character. If no flag is found, the player spawns at 0,0 in the top
corner of the map. Only use one Start Flag per level, otherwise the
player will randomly spawn at one of them.
* Crumbly Floor: a solid floor that begins to shake and then fall apart
after a moment when a mobile character steps on it. The floor respawns
after 5 seconds.
* State Blocks: blue and orange blocks that toggle between solid and
pass-thru whenever a State Button is activated.
* State Button: a solid "ON/OFF" block that toggles State Blocks back
and forth when touched. Only activates if touched on the side or bottom;
acts as a solid floor when walked on from the top.
New features for doodad scripts:
* Actor scripts: call SetMobile(true) to mark an actor as a mobile mob
(i.e. player character or enemy). Other doodads can check if the actor
colliding with them IsMobile so they don't activate if placed too close
to other (non-mobile) doodads in a level. The Blue and Red Azulians
are the only mobile characters so far.
* Message.Broadcast allows sending a pub/sub message out to ALL doodads
in the level, instead of only to linked doodads as Message.Publish does.
This is used for the State Blocks to globally communicate on/off status
without needing to link them all together manually.
* The `doodad` CLI tool got a lot of new commands:
* `doodad show` to verbosely print details about Levels and Doodads.
* `edit-level` and `edit-doodad` to update details about Levels and
Doodads, such as their Title, Author, page type and size, etc.
* Doodads gain a `Hidden bool` that hides them from the palette in
Editor Mode. The player character (Blue Azulian) is Hidden.
* Add some boolProps to the balance/ package and made a dynamic system
to easily configure these with the in-game dev console.
* Command: `boolProp list` returns available balance.boolProps
* `boolProp <name>` returns the current value.
* `boolProp <name> <true or false>` sets the value.
* The new boolProps are:
* showAllDoodads: enable Hidden doodads on the palette UI (NOTE:
reload the editor to take effect)
* writeLockOverride: edit files that are write locked anyway
* prettyJSON: pretty-format the JSON files saved by the game.
* Add animation support for Doodad actors (Play Mode) into the core
engine, so that the Doodad script can register named animations and
play them without managing all the details themselves.
* Doodad API functions on Self: AddAnimation, PlayAnimation,
StopAnimation, IsAnimating
* CLI: the `doodad convert` command will name each layer after the
filename used as the input image.
* CLI: fix the `doodad convert` command creating duplicate Palette
colors when converting a series of input images into a Doodad.
* Build the app with -tags="shareware" to compile the free/shareware
build of the game.
* `make build-free` compiles both binaries to the bin/ folder in
shareware mode.
* The constant balance.FreeVersion is true in the shareware build and
all functionality related to the Doodad Editor UI mode is disabled
in this build mode.
* CLI: fix the `doodad convert` command to share the same Palette when
converting each frame (layer) of a doodad so subsequent layers find
the correct color swatches for serialization.
* Scripting: add timers and intervals to Doodad scripts to allow them to
animate themselves or add delayed callbacks. The timers have the same
API as a web browser: setTimeout(), setInterval(), clearTimeout(),
clearInterval().
* Add support for uix.Actor to change its currently rendered layer in
the level. For example a Button Doodad can set its image to Layer 1
(pressed) when touched by the player, and Trapdoors can cycle through
their layers to animate opening and closing.
* Usage from a Doodad script: Self.ShowLayer(1)
* Default Doodads: added scripts for all Buttons, Doors, Keys and the
Trapdoor to run their various animations when touched (in the case of
Keys, destroy themselves when touched, because there is no player
inventory yet)
* Improve the `doodad convert` command to convert a series of input
images into multiple Frames of a Doodad:
`doodad convert frame1.png frame2.png frameN.png output.doodad`
* Add the initial round of dev-asset sprites for the default Doodads:
* Button, Button-TypeB and Sticky Button
* Red, Blue, Green and Yellow Locked Doors and Keys
* Electric Door
* Trapdoor Down
* Add dev-assets/palette.json that defines our default doodad color
palette. Eventually the JSON will be used by the `doodad` tool to give
the layers meaningful names.
* Add the JavaScript system for Doodads to run their scripts in levels,
and wire initial OnCollide() handler support.
* CLI: Add a `doodad install-script` command to the doodad tool.
* Usage: `doodad install-script <index.js> <filename.doodad>`
* Add dev-assets folder for storing source files for the official
default doodads, sprites, levels, etc. and for now add a JavaScript
for the first test doodad.
Adds the `doodad` binary which will be a command line tool to work with
Doodads and Levels and assist with development.
The `doodad` binary has subcommands like git and the first command is
`convert` which converts between image files (PNG or BMP) and Doodle
drawing files (Level or Doodad). You can "screenshot" a level into a PNG
or you can initialize a new drawing from a PNG.
