ECS

An extremely simple (~100 lines of code) Entity-Component-System implementation!

Usage:

import zero.utilities.ECS;

class Main
{

	static function main()
	{
		ECS.register_entity('human');
		ECS.register_component('human', 'position', { x: 0, y: 0 });
		ECS.register_component('human', 'velocity', { x: 1, y: 0 });
		ECS.register_system(new BasicMovement(), ['position', 'velocity']);
		for (i in 0...10) ECS.tick();
		trace(ECS.get_data('human', 'position')); // {x: 10, y: 0}
	}

}

class BasicMovement implements ECS.ISystem
{

	public function new() {}

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

}
