Region Spawns

[Drazhar]

Hey guys . Okay so i'm working on my maps' boss fight. And one component of it i'm struggling with. What I'm trying to do is have four regions throughout the room. And every, say 30 seconds, a tower will spawn in one of them. But I don't want anymore than 1 tower up every 30 seconds. There can be 2 up after 60 seconds, but not more than 1 per trigger activation. I also would like the spawns to be random, so it can end up in any of the four regions, but to check for a tower being already in that region so I dont have towers spawning on each other. Thanks

Edit: Going out, so my reply will be delayed. Thanks in advance to anyone who helps.

put a timer & condition in every trigger, then when trigger 1 is on, the trigger 2,3,4 should be off...when trigger 2 is on, trigger 1,3,4 is off and so on...condition must be unit type(tower)
