Hi there, I have a situation, kindly help me out.

I am creating instances of an entity randomly, and would want to remove one at a time as they make contact with another wall entity object. The problem is that I have looked at all the functions to remove entities, but I can’t figure out a way to remove one at a time; ONLY when that particular one makes contact with the wall, and not remove all the others that are being created even when they are not yet used. Is there a function I don’t know about to help achieve this?

 

By the way, I am following the sample tutorials to create something similar, and I am using “mousejoint” to drag these entities that are created at run time around. Unlike the Balloon example where U can pop using the “multitouch”, I am trying to achieve almost something similar, but this time, when it comes in contact with the wall.

 

Thanks

Hi,

you can do something like this in your entity:

// the collider of your entity
BoxCollider {
  // properties and stuff...

  fixture.onBeginContact: {
    // determine the entityType of the collided entity
    var fixture = other;
    var body = fixture.parent;
    var component = body.parent;
    var collidedEntity = component.owningEntity;
    var collidedEntityType = collidedEntity.entityType;
    // replace "wall" with the entityType of your walls
    if(collidedEntityType === "wall") {        
      // remove the entity
      removeEntity();
    }
  }
}

Is this what you are looking for?

Cheers,
Alex
