[Solved] Despawn a Barricade, using different object...

I'm back again, I seem to have a problem whether it's a Lack of Feature or I haven't figured how yet.
Anyhow, I'll try to explain what my Goal is... I have a Pillar with a "Soul" Collectable that when
collected, A Barrier is Despawned from the Tunnel Entrance allowing the player to Enter.

So far:
#1: I pooled the "Barrier" in PoolBoss.. Np so far

#2: Attached a Despawner Trigger on the Barrier hoping to find a option to Despawn,
when the "Soul" is Collected (the player shoots the item in Pillar)..

Result, it seems like the Despawner works only to Despawn object Attached to (with Event to that
object.) Anyhow I'm sure there's a great way to do this... k Ty..

Update! Solved... Basically I put the Barrier inside the Collectable so everything inside gets Despawned;
This seems to work by doing the Following:
1: Put the Barrier object inside the "Soul" item.
2: I pooled the "Soul" Collectable in PoolBoss, with a Despawn Trigger Event (Despawner) attached to "Soul" item.
Result... Kewl !!
Any other helpful suggestions, or if better method's I'd sure like to hear. Ty )
