I am trying to make several biuldings lift off and land over and over again, except I cannot see a trigger for it. tell me what i can do.
Use my system

It's perfect.
You can take off the cocoon centering triggers but it's not as accurate all the time.
Umm.. that isnt really what i meant... I mean not anti lifting... but to lift it up so that a unit can cross over... in your example.. it gives no time...
theres no trigger that makes a building lift off or land
yes that is why i am asking people how to do it. I know it isnt in the triggers. Something perhaps beyond?
THERE IS NO TRIGGER/BASIC METHOD
you need to have an acual player lift it off.
