(Experimental) Run Length Encoding for Levels Finally add a second option for Chunk MapAccessor implementation besides the MapAccessor. The RLEAccessor is basically a MapAccessor that will compress your drawing with Run Length Encoding (RLE) in the on-disk format in the ZIP file. This slashes the file sizes of most levels: * Shapeshifter: 21.8 MB -> 8.1 MB * Jungle: 10.4 MB -> 4.1 MB * Zoo: 2.8 MB -> 1.3 MB Implementation details: * The RLE binary format for Chunks is a stream of Uvarint pairs storing the palette index number and the number of pixels to repeat it (along the Y,X axis of the chunk). * Null colors are represented by a Uvarint that decodes to 0xFFFF or 65535 in decimal. * Gameplay logic currently limits maps to 256 colors. * The default for newly created chunks in-game will be RLE by default. * Its in-memory representation is still a MapAccessor (a map of absolute world coordinates to palette index). * The game can still open and play legacy MapAccessor maps. * On save in the editor, the game will upgrade/convert MapAccessor chunks over to RLEAccessors, improving on your level's file size with a simple re-save. Current Bugs * On every re-save to RLE, one pixel is lost in the bottom-right corner of each chunk. Each subsequent re-save loses one more pixel to the left, so what starts as a single pixel per chunk slowly evolves into a horizontal line. * Some pixels smear vertically as well. * Off-by-negative-one errors when some chunks Iter() their pixels but compute a relative coordinate of (-1,0)! Some mismatch between the stored world coords of a pixel inside the chunk vs. the chunk's assigned coordinate by the Chunker: certain combinations of chunk coord/abs coord. To Do * The `doodad touch` command should re-save existing levels to upgrade them.

Optimize memory by freeing up SDL2 textures * 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.

Doodad/Actor Runtime Options * 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.

Optimize memory by freeing up SDL2 textures * 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.

Doodad/Actor Runtime Options * 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.
