Working on a Convey WWII sub hunt module and it would be great if the torpedo launches could be hidden. Sort of transfer the invisible trait from the parent piece to the placed piece would be nice.
Only way around this that I found was to pull the sub into a private map, drop the torpedo then hide it and return them both to the main map.
You could have the basic image of the torpedo just be 1 pixel (sea color I assume) in each corner of the graphic. Then have a layer or mask that shows the torpedo for when it visible.
Or use a trigger command to
place the torpedo (no graphic)
send a GKC for that torpedo to go invisible.
send a GKC for that torpedo to flip to its visible layer (now that its invisible)
