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.
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.
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.
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
* 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`
* 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.
