ecx

ECX is Entity Component System framework for Haxe

• Asteroids Example
• Benchmarks

System

Injection

For example we need to inject TimeSystem system to our MovementSystem

class MovementSystem extends System {
    var _time:Wire<TimeSystem>;
    ...
    override function update() {
        var dt = _time.dt;
        ...
    }
}

Family

For example we need to track all active(live) entities with components: Transform, Node and Renderable

class MovementSystem extends System {
    var _entities:Family<Transform, Node, Renderable>;
    ...
    override function update() {
        // Note: typeof _entities is Array<Entity>
        for(entity in _entities) {
            // only entities with required component will be displayed
            trace(entity.id);
        }
    }
}

EntityView

EntityView is the utility class. It provides shortcut to edit entity using object-wrapper.

System Flags

• IDLE: System doesn't override update method. Should not be updated.
• CONFIG: System is defined with @:config meta. This system is just configurator. It will be deleted after World initialization phase.
• PROCESSOR: System has at least one entity Family to process.

Component

World

Initialization

var config = new WorldConfig([...]);
var world = Engine.initialize().createWorld(config, ?potCapacity);
