Maybe, I think they would stay about the same.  The List code really doesn't have much collision detection anyways, just the min max trick

Anyways, I'm starting to understand just how brilliant this code is... it is amazing how it works :)

But isn't it faster to do Repeat Ans:getKey:End:Ans->G ?

Where it has either A+(getKey stuff)->A and B+(getkey stuff)->B, or the x and y versions,

just add
Code: [Select]
min(8,max(1, to the Y axis variable
and
Code: [Select]
min(16,max(1, to the X axis variable
should work :)

Code: [Select]
ClrHome
4->X
5->Y
Repeat G=45
Repeat G
getkey->G
End
Output(X,Y,"
min(16,max(1,Y-(G=24)+(G=26->Y
min(8,max(1,X-(G=25)+(G=34->X
Output(X,Y,"@
End
ClrHome
StopThere you go! :)

EDIT: if you need me to, I can explain it for you

Note that this is only for collision on the screen sides, though.

Yes, but it should work for any sized rectangle (aka no walls in the middle of the screen :P )

Well thanks, but I was looking for collision with predrawn things. Like if I had on the screen a question mark, I wouldn't want to run through it

Here is a way to do that:
Code: [Select]
"
0ANYTHING000000  //Take out the newlines, of course, so the interpreter doesn't freak out
0             0
0             0
0     :)      0
00WORKS!!!1!100 ->Str1  //You can make the map bigger for more space to move

ClrHome
2->X
2->Y
Output(1,1,Str1
Repeat G=45
Repeat G
getkey->G
End
Output(X,Y,"
Y-(G=24)(sub(Str1,1,(X-1)16+Y-1) = "_")+(G=26)(sub(Str1,1,(X-1)16+Y+1) = "_->Y
X-(G=25)(sub(Str1,1,(X-2)16+Y) ="_")+(G=34)(sub(Str1,1,16X+Y+1) = "_->X
Output(X,Y,"@
End
ClrHome
Stop

I just kinda threw that together, but it should work.  It looks into Str1 to check if the space it is moving to is empty :)
It uses DJ's code, so you can easily modify it to this

It involves storing 24, 25, 26 and 34 in a list then doing Ξ”list or something for the movement, which is even smaller than my code. It was on TI-BASIC Developer somewhere.

Do you mean Repeat max(K={24,25,26,34}) ?

which part does it throw errors?
EDIT: maybe G is 45 BEFORE the loops starts. to prevent that, add DelVarG before Repeat G.
