HOTO snap to grid building TD style?

Let’s take for example - tower is 2x2 squares. How snap to grid tower preview after selecting tower type and before build with left click in TD style game?

Terrible solution i think is invisible squares, that detect mouse hovering, but i really don’t like this way.

I’m pretty sure the formula you’re looking for is something like this :

Tower X position = floor( Mouse X position projected on landscape / grid cell size X)

Tower Y position = floor( Mouse Y position projected on landscape / grid cell size Y)

I hope it helps.
