info: small location on unit, location follows unit using center location on bla bla bla
how do u make a trigger where unit has to stay on that location for some time in order to start an action? if it moves from the location, the time starts all over again
Have some sort of timer counting up (like a death count). If the unit leaves a location which auto-centers when unit leaves it, set the counter to 0.
no...I think thats pretty much it. Or you could use a countdown timer and do the same thing. Makes it more obvious to players.
The death-count timer method is a good and easy method.
