Really simplistic isometric 3D thing, basically there's a block in there called Translate Position where you pass it the x,y and z and it returns the x,y screen coordinate. I've added a grid and a (very) basic movement for forwards, backwards, left, right (arrow keys) and jump (space). This stuff starts to get complicated when things disappear behind other things and you need to draw everything in the right order. But this doesn't need to worry about that!
