Pushing entities in a array of Entities Reference

I am trying to push instantiated entities into a array of entity reference attached to component . So far it's just not working .

Code (CSharp):

1. this.world.foreach([game.Pooling] , (pool)=>{
2.     let clone = ut.EntityGroup.instantiate(this.world , game.ItemGroup)[0]
3.     pool.entities.push(new ut.Entity(clone.index , clone.version))
4. })

 

This has worked for me at times, maybe you could give it a try:

Code (CSharp):

1. this.world.foreach([game.Pooling] , (pool)=>{
2.     let clone = ut.EntityGroup.instantiate(this.world , game.ItemGroup)[0]
3.     pool.entities = this.addToArray(pool.entities, new ut.Entity(clone.index , clone.version));
4. })
5.  
6. /** Copies immutable array, adds specified element to it and returns the new array */
7. addToArray(original: ut.Entity[], newElement: ut.Entity): ut.Entity[] {
8.     let result: Array<ut.Entity> = original;
9.     result.push(newElement);
10.     return result;
11. }

 

I believe the reason its not working is because you have to add the entities to the array outside of the foreach and not inside of it
