Hello Yann... I am using your diablo like movement for my player character but I'm having a problem with her facing the right direction. She using 4 ways movement (left, right, up, down)
I had her set up with keyboard arrows (using mirror for left) but I want her to work on touchscreen mobile device.
Right now, she will go left and right after adding your code but she still faces right. I do not use all those directional animations you had. Just images for up, down, walk, still and shoot. I was using mirror to walk or shoot left with the left arrow key before...
