Hello there, I need help with buying a building in a 3D game. I want it were your mouse hover over a grid like plane and it turns green showing were you are going to click on. Then, when you click on it, it show so options for some buildings to place (turrets, solar panels, etc.) in a UI. And when you choose what you want to buy, it shows up where you first clicked on the grid.
Another ideas that would be cool is if you click on the building UI that you want to buy and it follows your mouse and snaps to the grid. When you click down on the place that you want it to be place, it will be placed down.
