OK I've been making a game for a little bit, lots of rectangles not many patterns so I've finally decided to use a tile set but i don't know how can anyone help? i have the file but i don't know how to incorporate it, can anyone help?
----here's my game
!!!! file can be found in assets>PNG's>Dungeon_Tileset.png
A side-note to @SPQR i have been very inactive recently but i'm back now if anyone could help, it would be you.
