Yea use his stuff. He was the one that actually made that trigger for me in the past and even made me a item system that is upgradeable and is also posted in that thread of his =)
The item upgrade system he made for me makes it so that when you click on that item it will take away a certain amount of gold away and it will wait over a period of time like 10 seconds or whatever and it checks to see if the item is still there after 10 seconds and if it is it gives the item. If its not there the money u used will come back.
A way he told me to do it, but i never did and am considering it for my new map is to switch the item out to a different item that is undroppable and then after the time is up to change it to the new item. Or if your familiar with the game battle tanks the upgrade system is basically the same as that in how it functions.
Under conditions, u cant have item being manipulated = to talisman A & item being manipulated = Talisman B. Because u cant acquire an item and it has 2 item types.
Its like a unit dies, unit type of trig unit = footman & unit type of trig unit = peon. How can a unit be both a footman and a peon?
The Or function works fine alone. delete the other 2 if item type = talis A & B
Personally, if you guys ever have any questions on a tutorial map you can always Post one here but also give me a pm here, on msn or aim, I might even get a yahoo if people request it. I just haven't been looking here for a while because I have been helping my grandmother and grandfather for the past 3 weeks.
