I would like to ask the map makers how to build multiple towers at a time like walls building with ctrl+ drag. Is there any option to modify in AdvancedGenieEditor if so can you please tell me that thanks you in advance
I don’t know anything about the Genie editor. However if in the editor I wanted to make, for example, 500 towers on a map, I would do it like this:
Make a block of 3x3 squares of towers (9 total).
Then use Map copy to copy that 3x3 block of towers.
Then paste 3 blocks of those 3x3 blocks of towers next to the first block of towers, giving me a square of 6x6 towers (36 towers). I’d then copy that square of 36 towers and paste as necessary. I could place 500 towers in a matter of seconds this way.
Obviously this only works if you need to place a lot of towers in the editor. If you are trying to change in game behavior of all players (which is what I think you are asking) I can’t help. I was just answering this question in case you were asking because you didn’t want to click 500 times to add 500 towers. 
thank you for the reply but not in map editing mod i want in game
