Well, I will provide the answer I found for the item vanishing. Lets say you want to spawn a TChest by a player carrying an object called "Master Key". I have a simple script titled "MasterKey" in my Custom Folder. On the XML Spawner, the first line will be the item you want t spawn. The second line of the spawner will have this typed - SETONCARRID,Master Key,MasterKey/DELETE So SETONCARRIED, name of item,scriptname/DELETE Now, when the item is spawned, it will remove the key at the same time.
I hope this helps someone
We miss you Arte..
