how do ATTR and SCREENS work?
I've tried to get collision detection to work but I'm not having any success. How do ATTR and SCREENS work?
In Heck, there are two options for perpetual torment:
Eat the Puckerberry and suffer for eternity:
drink nothing but a cocktail of The Last Dab and Mexican Cake blended and served with
habanero slices

Re: 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.
