Collision problems

[Lzrs111]

Hello,

I'm trying to make 4 invisible walls at the edges of my screen which should only collide with a certain type of Actor. I can only get these to partially work, since there always seems to be some issue. I need the walls to move with the player in the world and I need them to work on resize. So far I've tried:

1. setting the walls as Actors. Collision works, they move properly, but on going fullscreen there's a gap at the top. and bottom since world coords don't get translated to screen coords (I tried messing with engine.worldToScreenCoordinates and ScreenToWorld, but this didn't do much of anything).

2. Setting the walls as Actors with transformComponent coord.plane =CoordPLane.Screen works great on resize, but on movement their colliders seem to stay at the poisition they were originally created. So visually the walls are always moving, but not actually.

3. Setting the walls as Screen Elements - collision does not work, even with supplied collisiontype, width and height argument on creation. Not even Fixed type collision works.

Any ideas?
Thanks :)

I've figured it out, so here's some pseudocode for anyone interested:

class SomeClass extends Actor { 


  public update(engine: Engine) { 
     let bounds = engine.getWorldBounds()
        
     if (this.pos.x > bounds.right || this.pos.x < bounds.left {
        this.vel.x *=-1
    }
     
   if (this.pos.y > bounds.bottom || this.pos.y < bounds.top) { 
       this.vel.y *=-1   
   }

  }
}

Works on resize and there's no need to add any Wall actors or anything along those lines.
