Hi all, I am developing a 3d tycoon game. Basically, this genre is a game where you build something (like a city) using a grid. That´s why I am using Pro Grid to do so. There is a code question I still did not achieve to solve: how can I make players only be able to place their buildings only in grid holes? I mean, If you as a player are building your city and you want to place a building (maybe a store), how can I as developer code it to ensure that this building fit exactly into a grid hole and not between grids? I need to solve this dude using or not Pro Grid. I hope that my explanation is clear enough, if not, think in games like Clash of Clans, Dragon City, etc...All of them work in this way. Thanks.
