Bueno antes que nada pongo "MI" jueguito porque en realidad yo solo toke una parte xd.

bueno, vamos al grano:

miren, ya no recuerdo de donde, baje el codigo de un laberinto, y como me gusto mucho la idea,lo modifique:

Miren el original:

Si se dan cuenta, cambié, que en vez de que el camino sea un cuadradito blanco, y la pared sea un cuadrado gris, cambie para que con PaintPicture, dibuje texturas, bien eso funciona a la perfección.

pero el problema está en que están "corridas" las texturas.Por ejemplo, en la fila 2 hay camino y en la fila 1 hay pared,pero al momento de jugar el personaje se ve caminando sobre la fila 1, pero enrealidad esta caminando en la fila 2....

ojala que me puedan entender y ayudar...
