It would be nice to get a reply, basically im haveing some trigger help, i want after an ability is cast for it to take like60 lumber or 50 lumber, whatver from the units players current ammount or whatever.... its gona be done on a mass scale, several units useing it, doese that effect it?
Here's your reply! If you have hundreds of units using it at one time it might cause lag but otherwise probably not. basically do this:
Events: a unit starts casting an ability
Conditions: ability being cast equal to (your abil)
Actions: If/Then/Else Conditions:
Conditions: Current lumber of Owner of casting unit < whatever
Then - actions
order casting unit to stop.
Else - actions
set lumber of owner of casting unit to current lumber of casting unit - whatever.
Hope that helps or something. Somebody else may have a better idea.
