Grid Placement

I’d like to know how to make things center on a grid, if I place a tower, I want it to be centered on the grid. Examples?
Here’s my game- https://flowlab.io/game/play/1371445

Divide the position by 32 in an expression block

How do you do that?

Always>extractor(this x)>expression(a/32)>position-set x(grid)

Repeat for y

Where do I put the expression?

And It says that that it’s- unknown error: EUnexpected(X)

go to your tower logic, click on import and paste this into it:
