I seem to have forgotten a most important option on the item for the second method being: Use automatically when aquired = TrueThe first method I did not find this function in the triggers (remembering that I am using WE 1.26) and the second method did not work, because every time I activate the trigger it gives a new item that is filling the space in the inventory until it is full, after 6 items it starts to drop.
You could try this but it might not be compatible with your editor versionIt is possible to do this in jass?
