Title: Playing IFF Anims in Amos Pro
Post by: Amiten on June 19, 2013, 11:48:17 AM: Hello Amos Fans!,

I try to play some IFF anims in Amos Pro and I found this issue....

I make the anim in DPaintV with 79 Frames (iff images) and change the Frame Rate to slow the Animation and there every thing Fine then I save the IFF Anim and go to Amos Pro.

In Amos Pro start the Issue.

I write this little program to play the IFF Anim

screen open 0,288,200,32,lowres
screen 0
iff anim "level1" to 0,1
do
loop

well the animation play ok all frames in correct frame rates BUT the colours its totally diferent from the DPaintV animation :-[

I use 79 images of 32 colours each but diferent palettes each one - may be this is the problem?¿

I think Amos Iff Anim Player Get the palette from the 1 Image and then Apply this palette to The Rest
Rigth? or not?

in that case how I can Fix this problem to make the Anim Result the same does in DPAINTV but in Amos.

thanks for advance, king of regards

There aren't extension to solve this problem, you can remake the animation with one palette for all Frames, or you can change the palette by yourself, playng animation inside a loop, and before displaying the frame change the palette...

N=number of frames of the animation

Could you provide example code example, please? Uncompiled .amos file with small .anim would be great. Thanks in advance

Could you hint me which part of AMCAF should i focus on about possibility of every frame palette changing anims?
