SpriterHaxeEngine

The point of this project is to offer a Brashmonkey's Spriter SCML renderer compatible with Haxe 3 and openfl. Base code of SCML definitions from http://www.brashmonkey.com/ScmlDocs/ScmlReference.html

Inspired by

• https://github.com/Acemobe/SpriterAS3Anim
• https://bitbucket.org/ClockworkMagpie/haxe-spriter/
• https://github.com/ibilon/HaxePunk-Spriter

Install: haxelib install SpriterHaxeEngine

Choose your drawing library:

/**
* Example with the TilemapLibrary which uses openfl-atlas (haxelib install openfl-atlas)
*/
//set the root canvas where to add all the animations
var spriterRoot:Sprite = new Sprite();
addChild(spriterRoot);
//get an atlas
var tileset:TilesetEx = new SpriterTileset(Assets.getBitmapData('assets/atlas.png'), Assets.getText('assets/atlas.xml'));
//choose a rendering method.
var lib = new TilemapLibrary([tileset], spriterRoot, stage.stageWidth, stage.stageHeight);

/**
* Example with the BitmapLibrary which uses BitmapData.copypixels() and BitmapData.draw()
*/
//set the root canvas where to add all the animations
var canvas:BitmapData = new BitmapData(800, 480);
var spriterRoot:Bitmap = new Bitmap(canvas, PixelSnapping.AUTO, true);
addChild(spriterRoot);
//choose a rendering method.
var lib:BitmapLibrary = new BitmapLibrary('assets/', canvas);

/**
* Other libraries exist to use Spriter with flixel and other rendering method!
*/

Instantiate the engine:

//Create the engine.
//you can specify a default scml or you can specify it later in addSpriter()
engine = new SpriterEngine(Assets.getText('assets/test.scml'), lib );
		
//Add a Spriter in the engine. A Spriter contains all data from the scml (all entities, animations, boxes, tags...)
//By default, it will play the first animation of the first entity of your scml
engine.addSpriter('uniqueId', x,  y);

//Set the "run" animation of the entity
engine.getSpriter('uniqueId').playAnim('run', myCallback);

//Apply the "gun" map of the entity
engine.getSpriter('uniqueId').applyCharacterMap('gun', true);

//Update on enter frame to draw all Spriters on screen
engine.update();

//Callback on end anim
function myCallback(s:Spriter):Void

//callback
engine.getSpriterAt(0).onVarChanged = function varCallback(name:String, value:Dynamic):Void{}
engine.getSpriterAt(0).onEvent = function eventCallback(name:String):Void{}
engine.getSpriterAt(0).onSound = function soundCallback(name:String):Void{}

//current points and boxes
var points:Array<SpatialInfo> = engine.getSpriterAt(0).points;
var boxes:Array<Quadrilateral> = engine.getSpriterAt(0).boxes;

//current tags
var tags:Array<String> = engine.getSpriterAt(0).tags;

//current variables values
var value:Dynamic = engine.getSpriterAt(0).getVariable('myVar');


//stack anims
engine.getSpriter('uniqueId').playAnimsStackFromEntity("entityName", ["anim1","anim2"], myCallback).

Spriter Haxe Engine Features

SCML API

Engine

• Can be overrided to fit your need
• simple z-ordering
• Fixed tick, variable tick or use your own time
• Pause
• simple auto removal
• default scml

Spriter entity

• character mapping by name
• change animation easily by name in a Spriter entity
• callback when animation ended
• play, stack anim, pause
• you can display duplicate of spriter entity and manipulate them separatly
• callback when events, sounds are triggered
• callback when variables change
• Points (usage example : to shot a bullet when gun fire)
• Boxes (usage example : hitbox)
• Tags (usage example : state vulnerable)
• sub entities
• playing backward and reflect

Libraries

• TilemapLibrary (use openfl tilemap, dependency: openfl, openfl-atlas)
• Simple bitmap library (bitmaps handled with addChild, dependency : openfl)
• BitmapData library (copypixels, dependency : openfl)
• Tilelayer library (drawTiles using only one tilesheet)(dependency : openfl-tilelayer and openfl).
• DrawTiles library (using many tilesheets)(dependency : openfl-tilelayer and openfl).
• Flixel Library (atlas support or bitmaps handled with addChild, dependency : flixel) by Zaphod
• Heaps Library (h3d/heaps, dependency : heaps ) by Delahee
• Luxe Library (dependency : luxe )
• override the AbstractLibrary to provide a new library

Other features

• own texture packer exporter
• macro to parse scml into binaries

Cross-platform

• flash
• windows
• neko
• android
• html5

TODO

• interpolation on variable
• variable/tags of sub entities
• add tilesheet stage 3d support : https://github.com/as3boyan/TilesheetStage3D/
• add ash and haxepunk support
• add Flambe support (waiting for pull request, see here https://github.com/quinnhoener/SpriterHaxeEngine)
• add Kha support (waiting for pull request, see here https://github.com/sh-dave/SpriterHaxeEngine/tree/dev)
• Optimized engine : draw call only when needed. So "instant" keys are not updated between keys.
• animation callback optimization
• check Garbage collector

WIKI

The wiki provides more details on features and how it works.

Examples

• Please see this repo : https://github.com/loudoweb/Spriter-Example

Additional information

• compatible with Spriter r6.1

• With Tilelayer library, don't use openfl-bitfive for html5 target.

Known issues

• Please use the best rendering method according to your target.
