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 it: haxelib install SpriterHaxeEngine

Configure it:

//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);

//you can use a different library to feet your needs. This one use BitmapData.copypixels() and BitmapData.draw()
var lib:BitmapLibrary = new BitmapLibrary('assets/', canvas);

//here is the engine : it will update all your Spriter's entities
engine = new SpriterEngine(Assets.getText('assets/test.scml'), lib, null );
		
//to add and entity
engine.addEntity('entityName', x,  y);

//set the "run" animation of the entity
engine.getEntity('entityName').playAnim('run', myCallback);

//apply the "gun" map of the entity
engine.getEntity('entityName').applyCharacterMap('gun', true);

//update on enter frame
engine.update();

//callback on end anim
function myCallback(s:Spriter, entity:String, anim:String):Void

//var and tag callback
engine.getEntityAt(0).scml.tagCallback = function tagCallback(tag:String):Void{}
engine.getEntityAt(0).scml.varChangeCallback function varCallback(variable:Variable<Dynamic>):Void{}

//points and boxes
var points:Array<SpatialInfo> = engine.getEntityAt(0).getPoints();
var boxes:Array<Quadrilateral> = engine.getEntityAt(0).getBoxes();

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

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 variable changes
• callback when tag dispatches
• Points (usage example : to shot a bullet when gun fire)
• Boxes (usage example : hitbox)
• sub entities

Libraries

• Simple bitmap library (bitmaps handled with addChild, dependency : openfl)
• BitmapData library (copypixels, dependency : openfl)
• Tilelayer library (drawTiles using only one tilesheet)(dependency : https://github.com/elsassph/openfl-tilelayer and openfl).
• DrawTiles library (using many tilesheets)(dependency : https://github.com/elsassph/openfl-tilelayer and openfl).
• Flixel Library (atlas support or bitmaps handled with addChild, , dependency : flixel) by Zaphod
• override the AbstractLibrary to provide a new library

Cross-platform

• flash
• windows
• neko
• android
• html5

TODO

• 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)
• Optimized engine : draw call only when needed. So "instant" keys are not updated between keys.
• animation callback optimization
• check Garbage collector
• binary scml
• use multiple scml in the engine

Examples

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

Additional information

• compatible with Spriter r3
• With Tilelayer library, don't use openfl-bitfive for html5 target.

Known issues

• [html5] some issues on html5 depending on the backend used and the Library used.
• Please use the best rendering method according to your target.
