I've tried to get collision detection to work but I'm not having any success. How do ATTR and SCREENS work?
The short answer: RTFM
The polite answer:
ATTR(Y,X) returns the setting of the colours on that field.
So when your last printed character there is a different INK or PAPER then you will get that in return with something like LET A=ATTR(Y,X)
SCREEN$(Y,X) can return the printed character there but only when that character is part of the characterset, so UDG will normally not work.
