History

Noah cf1bc81f25 Update savegame format, Allow out-of-bounds camera 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.		2023-03-07 21:55:10 -08:00

doodad.exe

The doodad tool is a command line interface for interacting with Levels and Doodad files, collectively referred to as "Doodle drawings" or just "drawings" for short.

Commands

doodad convert

Convert between standard image files (bitmap or PNG) and Doodle drawings (levels or doodads).

This command can be used to "export" a Doodle drawing as a PNG (when run against a Level file, it may export a massive PNG image containing the entire level). It may also "import" a new Doodle drawing from an image on disk.

Example:

# Export a full screenshot of your level
$ doodad convert mymap.level screenshot.png

# Create a new level based from a PNG image.
$ doodad convert scanned-drawing.png new-level.level

# Create a new doodad based from a BMP image, and in this image the chroma
# color (transparent) is #FF00FF instead of white as default.
$ doodad convert --key '#FF00FF' button.png button.doodad

Supported image types:

PNG (8-bit or 24-bit, with transparent pixels or chroma key)
BMP (bitmap image with chroma key)

The chrome key defaults to white (#FFFFFF), so pixels of that color are treated as transparent and ignored. For PNG images, if a pixel is fully transparent (alpha channel 0%) it will also be skipped.

When converting an image into a drawing, the unique colors identified in the drawing are extracted into the palette. You will need to later edit the palette to assign meaning to the colors.
