Collision Confusion

[cemalgnlts]

Hi,
Here are the properties of my bomb class:

constructor(x, y) {
  super({
    name: "Bomb",
    x,
    y,
    z: 3,
    collisionType: ex.CollisionType.Active,
    collider: ex.Shape.Box(25, 30, ex.Vector.Half, ex.vec(0, 18)),
  });

  this.body.group = ex.CollisionGroup.collidesWith([
    ex.CollisionGroupManager.groupByName("solid")
  ]);
}

It can only interact with solid (ground).

This is the child Entity I added to my Bomb object when my Bomb object exploded:

onExplodeStart() {
  this.graphics.use("explotion");

  const colliderComp = new ex.ColliderComponent(ex.Shape.Circle(50));
  const bodyComp = new ex.BodyComponent();

  const explosion = new ex.Entity([
    colliderComp,
    bodyComp
  ], "explode");

  bodyComp.collisionType = ex.CollisionType.Passive;
  bodyComp.group = ex.CollisionGroup.collidesWith([
    ex.CollisionGroupManager.groupByName("player")
  ]);

  colliderComp.events.on("collisionstart", (ev) => this.onExplodeInteract(ev));

  this.addChild(explosion);
  this.clock.schedule(() => explosion.kill(), 100);
}

It can only interact with the Player object.

Also Player object:

constructor(x, y) {
  super({
    name: "player",
    x,
    y: y - 29,
    z: 2,
    collisionType: ex.CollisionType.Active,
    collisionGroup: ex.CollisionGroupManager.groupByName("player"),
    collider: ex.Shape.Box(30, 50, ex.Vector.Half, ex.vec(0, 4)),
  });
}

The problem is that when the explosion entity explodes, it interacts with the bomb object. However, it should only interact with the Player object and not with the Bomb, which is its parent.

If I tell the Explosion object to interact with the Solid(ground) and not the Player:

ex.CollisionGroup.collidesWith([
- ex.CollisionGroupManager.groupByName("player")
+ ex.CollisionGroupManager.groupByName("solid")
]);

This way it only interacts with the ground, not its parent Bomb object. In fact, when I said Player, it should only interact with the Player.

Of course, since I'll be using if, it's okay to interact with objects I don't want. Maybe I made a mistake somewhere.
