Hello!
it is extremely important to give the height of the sprites each time!! Especially those of the characters. We can not work with 32x32 characters with 48x48 characters. And when you put the height of the character it is the height of the character and not the height of the sprite!! It is very important, I often find myself with characters that are not at all the same sizes and it is impossible to use.
Thank you for your attention.
