class ECS

An extremely simple Entity-Component-System implementation!

Usage:

• Entities are just integers, but you register and look them up using Strings: ECS.register_entity('player');
• Components are just sets of data tied to an entity: ECS.register_component('player', 'position', { x: 0, y: 0 });
• Systems are classes with an update() function that modify data. The update function is fed delta time and an array of entities.
• In your system's update() loop, you can use ECS.get_data() to get the relevant data:
• for example:

	Class MoveRightSystem implements ISystem {
		public function new() {}
		public function update(dt:Float, entities:Array<String>) for (entity in entities) {
			var position = ECS.get_data(entity, 'position');
			position.x++;
		}
	}

• When you have a System set up, register it and give it a list of necessary components: ECS.register_system(new MoveRightSystem(), ['position']);
• To update all registered systems, use the tick function: ECS.tick(1/60);
• You can also delist entities, components, and systems.
