Is there multiple ways to destroy an entity group?

Currently I'm using this method

this.world.destroyEntity(entity);

I tried it with behavior and typescript system but it always gave me an error and the game will just freeze.



Full code:

Code (JavaScript):

1. let dt = this.scheduler.deltaTime();
2.  
3.             this.world.forEach([ut.Entity, ut.Core2D.TransformLocalPosition, game.Scroller],
4.               (entity, position, scroller) => {
5.  
6.                 let p = position.position;
7.                 p.x -= scroller.Speed * dt;
8.                 position.position = p;
9.  
10.                 if(position.position.x <= -2) {
11.                     console.log("DESTROYING PIPE!");
12.                     this.world.destroyEntity(entity);            
13.                  }
14.               });

 

Thank you so much! I think it worked, but I still get 1 warning, and I'm not sure what It means or if it's okay to just ignore it.

Thanks for the help.
