Question

Hello ! I am really new and trying to create my first game, it’s possible that i missed an important point in one of the many tutos i watched, so my apoligies if the question is dumb.

I am trying to use a tilemap in black and white of 16*16 (the size is obviously not important), to generate a dungeon map, the idea is that if the tile is white there is a room, if it’s black there is no room.

I just need to understand how to “read” the map, a tile after another :confused:

Again i’m sorry if it’s dumb, a link to a tutorial or even a simple advice could help me,

thanks for the help and have a nice day !
