Unit Building Limits

[RCS12]

How can I do this?

I build an aura tower and I only want it to be built once, but it will still appear in building list. I want this to happen: When you try to build and you have already built that building, it will cancel the order. How can I do this?

When an Aura Tower is finished being built set a boolean to True.

Build trigger
Events - A unit beings constructing
Conditions - (Unit-type of (Constructing structure)) Equal to Aura Tower and Aura_Tower_Boolean Equal to True
Actions - Remove Constructing structure from the game

Third trigger
Events - A unit dies
Conditions - Triggering unit Equal to Aura Tower
Actions - Set Aura_Tower_Boolean to False

If you want this to be MUI you need to uses arrays.
