Area

Prototype class

Area allow to known if one or multiple target enter or exit a area. This one is represented by an actor in your game. Take the following example for Door in echo of life :

class DoorBehavior extends United.Behavior<Game> {
    
    distanceArea: number = 1;
    sceneName: string;
    areaPools: United.Area.Pools;

    awake() {
        if(!United.Engine.hasScene(this.sceneName)) 
            throw new United.Exception.InternalError("Impossible de déclarer une door sans une scène de destination!");
        this.areaPools = new United.Area.Pools(this.actor);
        this.areaPools.addTarget(this.$.player,this.distanceArea);
        this.areaPools.on("in",() => {
            if(!this.$.paused && this.$.control.USE.wasJustPressed()) {
                United.Engine.activeScene = this.sceneName;
            }
        });
    }
    
}
Sup.registerBehavior(DoorBehavior);

You can catch four types of events :

• in (update event)
• out (update event)
• actorIn (one event when he enter into the area)
• actorOut (one event when he exit)

Each of these events have for argument the focused actor.
