Charset animation problem
Hi there.
I known how to animate a charset that contains 8 charsets. Which is something like this:
CHARANIM INC ANIMPOINTER
LDA ANIMPOINTER
CMP #$08
BNE ENDANIM
LDA #$00
STA ANIMPOINTER
JSR ANIMATE
ENDANIM RTS
ANIMATE LDX #$00
WRAPCHR LDA $0A00,X
STA $0A40,X
INX
CPX #$08
BNE WRAPCHR
LDX #$00
WRAPCHR2 LDA $0A08,X
STA $0A00,X
INX
CPX #$40
BNE WRAPCHR2
RTS
Easy eh? Unfortunately, I'm trying to animate a charset which somehow has a bigger animation. The animated chars are from $0910-$0a40. Please can you help me get an accurate animation for chars $0910-$0a40 (Putting $0a40 to $0910 and wrapping the frames for all the chars from that range :( ? |

Do you really need to display all animation phases at the same time? In other words, can't you just copy the current phase to one character once every frame? |

That's what I thought he was trying to ask, which is why I wasted some time writing that routine I posted a few hours ago.
I think Richard is saying that he wants to view more than one char on the screen which use the same animation data.
But again!- that routine i posted could be used MULTIPLE times to write animation to different individual chars of any set/bank if you think about it. Modifications need to be applied of course. |

Thanks for your help :)
I'm probably better off using less than 39 chars because of too much rastertime being used :( |

39 chars * 8 bytes * 8 cycles / 63 cycles = about 40 rasterlines. Does not sound much to me. |
