All the positions have already been mapped out for you, but you can make some changes if you want. Left key to move to the previous sprite, right key for the next. With your mouse, you get to control where the shell is when Luigi holds it! Just click, and for that specific sprite, the shell will be in that position! The small dot indicates where it is! There is also a preview at the top right of the screen of how it looks.
Nintendo for the Super Mario All Stars Super Mario World Luigi sprites and Athletic theme. You know what's always bothered me about Super Mario World? How when Mario/Luigi is holding a shell, they bob while running up and down, but the shell isn't. I made this to see what it would look like if the shell actually moved with the sprite too. I did this by making a list that has 2 values in it assigned to each sprite. The X and Y position for the item. I rendered the sprite, then the dot, and made it so that when you hold down the mouse it overwrites the assigned data with the current mouse position. This was surprisingly hard to do. The rest were finishing touches, top right preview (the shell's position is slightly offseted, actually), and you can see which costumes are next.
