pool

The pool component allows for object pooling. This gives us a reusable pool of entities to avoid creating and destroying the same kind of entities in dynamic scenes. Object pooling helps reduce GC pauses.

Example

For example, we may have a game with enemy entities that we want to reuse.

            
              <
                a-scene
                pool__enemy=
                "mixin: enemy; size : 10">
              </
                a-scene>
          

            
              varel = sceneEl.components.pool__enemy.requestEntity();
            sceneEl.components.pool__enemy.returnEntity(el);
