I have a spawner set to spawn some decorative plants, trees and such - a living forest as it were - but I want it to change regularly. I have the spawner set with a min/max of about 1 second, but I would like a plant to appear, and decay after a time interval to be replaced by another plant one second later in the spawn area, thereby giving me a forest that is ever changing... I cant seem to figure out how to make it so the players cant move or take trees and still have it accomplish what I am trying for.

Ideas?

spawn them as movable/false so they cant be taken but set the Duration property on the spawner to the length of time that you want them to last and they will be despawned after that time elapses after they are spawned.

The problem is that I dont want the entire forest to poof at once and then pop back in a piece at a time. I would like the individual plants on the spawner to do that if one comes in each second I would like one to go out and be replaced each second, otherwise the whole forest poofs and then slowly comes back.

That make sense? Im blonde and dont always express my thoughts well.

yes. In order to do that, you need to have separate decay timers associated with each item. I would use the TemporaryQuestObject attachment for that. It allows you to tag individual objects and have them deleted after some time period.
So just spawn your items with the attachment like this

tree/ATTACH/temporaryquestobject,,20

and the item will be deleted after 20 minutes. The example uses an empty questname argument, since you dont need to associate it with any quest, you just want to autodelete after some time.
