Ok to go with my save game Capx here's a level creator maybe for a sim type game, this is very basic but works, there maybe bugs,
on first screen click on Goto Editor Button
Left click to Select Road,Dirt,Water ETC
Right Click to Place on Map
To delete any items placed Hover mouse of object and press delete
I know it's far from complete, and if you delete the tiles in the left window then oopss they are gone... But it's a start for someone.
Also a snap to grid would be good for this, which i'm working on next.
