Heyho,
first of all, sorry for my bad english  :<

Im trying to programm a little game, where i need some interfacegraphics.
The red color of the brain (image attached) shall get smaller, if the player gets hit.
map() should be a good option for that, but i have to crop the image of the brain and not just change the width..
Any ideas how to solve that? Is there a function, which crops my image :o?

tldr; the red brain shall change his width by cutting the rest and not by deforming.


greets
Philipp
