Stop, from doing what ?
Training ? Constructing ? Building ?

Spelling,Casting,Channeling,....
I tried with triger but no use ( cause no button )

Tell me, what can your "building" do ?
It can... cast spell ?

Or building unit, in terms of you train the unit ?

I use casting a spell for making item ( try grill a pork that it )
if there someone try take item from it, it will stop ( for the bug that it grilling a pork and drop item then the raw pork still there but the grilled pork is make )

Now, that's a fair description indeed
I'll try to create something for you.
