I haven't player Miner's Haven, but this seems like a fun thread, so I'll give it a shot. :D
You can try to track the player's mouse similar to how the build and delete tools work from building a place, not editing. You can work from there and clone the tower from the lighting, turning it's transparancy to 0.5 and its CanCollide property to false. Create a function that, when the mouse moves, it should reset the position according to the mouse in terms of studs. Sounds a bit complex, but...yeah, it is. :P
Hope this helped ^~^ |
