Help required: how to setup a trigger when the player grabs an item

[Bikerdude]

In this instance I have a special loot item in an underground location that when the player grabs the item it trigger a atdm:teleport entity which target an Ai.

 

What the very simplest way I can accomplish this..?

 

Well I never, just targeting the relay (which itself targeted the teleport entity) from the special loot item did the trick..

Simplest way is to use stim/response on the frobbed object. Create a frob response and have it trigger a trigger_relay with "wait" set to -1. The trigger_relay can target the teleporter. This way when the player frobs the object it will activate the teleporter, but only once.

I just figured something similar, see above.
