Help ... for once i've decided to stop my 'blast the system and poke the hard-
ware' bad programming habits and i'm now stuck for a silly thingy ...
I want to include a bunch of copper instruction to make some color effects in
a screen view viewport copper list ...
i guess i should use InitUcopperList,Cmove,Cwait and Cbump but how ???
is something like that correct :
lea myownucoplist,a0
moveq #instnum,d0
jsr InitUcoplist(a6) ; a6 contains gfxbase
move.w #register,d0
move.w #data,d1
jsr Cmove(a6)
jsr Cbump(a6)
move.w #vpos,d0
move.w #hpos,d1
jsr Cwait(a6)
jsr Cbump(a6)
etc .. etc ..
move.w #10000,d0
move.w #255,d1
jsr Cwait(a6)
jsr Cbump(a6)
and then
move.l a0,MyScreen->MyViewPort->Ucoplist
and then call mrgcop to get it ok ????
Please someone help me or i will go back to my wild poking ...
any reply welcome at CREMMER@CERNVM.CERN.CH because i don't have access
to the news so often ...
thanks alot,cheers.
