Is it possible to create a building using a trigger that is still under construction?
For ex: You make a rpg about a building site construction so everytime a day passes you have like a unfinished cc jump from 10% to 20% done but you can't see it being constructed(the hp going up) between the days
no.
I THINK some sprites of buildings appear as half constructed, but u cant create sprites with triggers.
no its not possible like screwed said but maybe you could make the cc take a long time to build with an scv and time it to do like 10% for each day you made.
