Collision attr routine. - compiuter - 2011-03-06
I was thinking about any routines that get attr positions up, right, down and left for one character of x,y position.
-p-
qAr
-s-
And the same for a tile
-pq-
rABt
sCDu
-vw-
and poke those valours into printer buffer or into a variable address, etc.
I'm tired for repeat the same sentences IF ATTR in basic listing cause is a heavy job.
I have no time now, but if someone has free time for this and they want...
I think this can be a library called e.g. ATTTR.bas or ATTTR.asm
Thx.

Why not write a subroutine which pokes these values into printer buffer? Like: POKE buf,peek(attradr-32)
OKE buf+1,peek(attradr-1)OKE buf+2,peek(attradr+1)OKE buf+3,peek(attradr+32). This is not standard BASIC function, and I don't think, it will be of any use for other users.

Tanks, I was thinking in zx basic. Yours is a good system.

I have added AttrAddr(y, x) function in attr.bas library in the latest version 1.2.8r2139
I was thinking exactly the same:
Code:
#include <attr.bas>
Sub GetAddr(y, x, buf)
Dim attraddr as UInteger
attradr = AttrAddr(y, x)
POKE buf,peek(attradr-32)
POKE buf+1,peek(attradr-1)
POKE buf+2,peek(attradr+1)
POKE buf+3,peek(attradr+32)
End SubRe: Collision attr routine. - compiuter - 2011-03-09
Thanks.
Re: Collision attr routine. - compiuter - 2011-03-11
I was testing the routine and trying news clock sense orientet and with diagonals, and proyected tile clock and diagonals version.
I find that e.g. peek 23400=111
and if in 23401 is filled with 222
then peek 23400+1 play 112 instead 222
Is It like Zx Basic or changed for the compiler?

Here is my testing routines clock sense oriented.
I am thinking about use parameters for the sprite height and wide, and made a dinamyc routine for whatever typè of sprites.

Code:
#include <memcopy.bas>
#include <sinclair.bas>
#include <keys.bas>
#include <attr.bas>
