ugh ok another thread about maps
ok so what i did was i made the levels then linked them. Then i made a txt file that looks like this:

"island_a-1.nw","island_b-1.nw","island_c-1.nw","island_d-1.nw"
"island_a-2.nw","island_b-2.nw","island_c-2.nw","island_d-2.nw"
"island_a-3.nw","island_b-3.nw","island_c-3.nw","island_d-3.nw"

ok so i saved the txt file in the same folder as the levels, and i opened the editor and pushed M, and it asks if i want to generate a map, so i say ok and save it as graalmap.png, in the same folder as my levels and the txt folder. I put the script:

setmap graalmap.png,island_a-1.nw,30,30;

Then i play the level and the map image is completely black.
Oh and i read the other thread and tried walking around the map but it still remains all black
Can anyone help me out i don't know what is wrong with it -_-
