openfl-simple-particles
=======================
A simple particle system for [openfl](http://openfl.org).
[ 1.0.0 Demo ](http://underscorediscovery.com/sven/openfl-simple-particles/)
Click to toggle emission, move mouse to move system.
##Usage :
- Copy the particles/ folder into your source folder. **OR**
- haxelib git this repository
- Will add to haxelib when more tested
- Create a new particle system,
- `var system : ParticleSystem = new ParticleSystem( new flash.geom.Point() );`
- Add an emitter
- `system.add_emitter('smoke1', { particle_image : openfl.Assets.getBitmapData("assets/smoke.png") });`
- Start the system emitting
- `system.emit( duration_in_seconds ); //default is -1, infinite emit`
- Add to the stage
- `addChild( system );`
##Emitter template values
-Values that you can pass into the { } to the add_emitter function:
particle_image = BitmapData
cache_size = 100; //max number of sprites
emit_time = 0.1; //seconds
emit_count = 1; //number of sprites at each emit_time
life = 1.0; //seconds
life_random = 0.0;
gravity = new Point(0,-3);
pos = new Point();
pos_offset = new Point();
rotation = 0.0; //degrees
end_rotation = 0.0; //degrees
rotation_offset = 0.0; //degrees
direction_vector = new Point();
direction = 0.0; //degrees
direction_random = 0.0; //degrees
speed = 0.0;
speed_random = 0.0;
start_size = new Point( 32,32 );
end_size = new Point( 128,128 );
start_color = new Color( 1,1,1,1 );
end_color = new Color( 0,0,0,0 );
-The random values are "delta" based, if start is 32 and random is 32, it will be between 32 and 64
rotation_random = 360.0;
end_rotation_random = 360.0;
pos_random = new Point( 0,0 );
start_size_random = new Point( 0,0 );
end_size_random = new Point();
start_color_random = new Color( 0,0,0,0 );
end_color_random = new Color( 0,0,0,0 );
##Known Issues :
- Supports color internally but does not apply it to the sprite (only alpha is applied atm)
##License :
- MIT license (see LICENSE file for more)
