I'm having problems when opening, I get this error:
Error
grid.lua:13: attempt to index local 'file' (a nil value)
Traceback
grid.lua:13: in function 'loadExternalImage'
grid.lua:22: in function 'load'
main.lua:31: in function 'load'
[C]: in function 'xpcall'
[C]: in function 'xpcall'
any advice?
edit: I got it working, i forgot to add a tileset in the tileset folder
