You'll find the tiles mouseX and mouseY in the playfield category of a playfield or of the world.
get an arrow fom object catalog/graphics
move the ble rotation handle sligtly to make te center or rotation visible and move it shift/drag to the foot of the arrow.
get the viewer of the arrow category polygon, et the arrow's vertex .cursor to 2 (head of the arrow).
now just build the tiles :
arrow's x at cursor _ playfield's mousex
arrow's y at cursor _ playfield's mousey
You probably just need to find where the tiles mouse and mousey were lying, but this will help other people.
