Why do you initialise sourceX at 32? -- |

I don't know, in the tutorial that i've saw the code is like this... I tried changing the values but nothing... What could be? Thanks : ) |

The original example must have used a character of width 32, so sourceX=32 picks the "middle" column, where the character has both feet on floor. Try using the attached image, I re-aligned your character, individual sprites are now 39x48. It's a GIF, I couldn't find a good program for 32bit PNG at the moment - I hope it will load OK on OSX. int dir = DOWN, sourceX = 32, sourceY = 0; sourceX = 32; al_draw_bitmap_region(player, sourceX, sourceY * al_get_bitmap_height(player) / 4, 32, 32, x, y, NULL); |

It works, but, when i move to the RIGHT the animation go UP, when I move DOWN, the animation go to the LEFT, when I move UP, the animation go DOWN and when I move to RIGHT the animation go up, do you know what could be? |

The original example must also have the sprites ordered differently... |
