How do you get something like maplet's grid selector? can someone post some code examples I want to understand how to do this.

First, create a plane and make sure it is in view. Then, make it pickable using EntityPickmode plane, 2 In your main loop, use CameraPick camera, mousex(), mousey() After that, use PickedX/Y/Z to read the picked coordinates. To convert the coords to a grid, use Int: xx# = Int(PickedX()) yy# = Int(PickedY()) zz# = Int(PickedZ()) To scale the grid, first multiply PickedXYZ and then divide it again. Ie: xx# = Int(PickedX() * 2) / 2.0

I don't understand the multiply part, why do I need to do this?

You only need it if you want to make the grid bigger or smaller.

this will allow you to have something like a thin pillar as not everything is 1,1,1 big
