ok, forget translate

here is a version with working UP and SHIFT

in this version ALL 5 keys change color

you need to do a bit of house cleaning in the code (no pun intended)
so that all windows use the same color (for example)

Don’t be discouraged!

You can do it!

It was a problem that the color you changed in keyPressed were not used in house() - there were other colors like c4 used…

:wink:

I placed translate() at the start of house to move all that gets drawn afterwards up and to the left

So the house can be placed everywhere in the window; before that it was too far right and down.

See reference for translate
