Title: Animation on Amiga/in AMOS
Post by: Philski on January 04, 2009, 05:43:11 PM

I've just started doing some animation using Personal Paint and have 4 frames with separate colour palettes (low res 16 colour).

When I try and play this inside of AMOS it freaks out - I assume because of the varying palettes.

Does anyone know if it is at all possible to create a single palette shared by all the frames (using half bright perhaps) in PPaint or is there a way to get Amos to create a palette for each frame?

Thanks in advance

Phil

With Amiga, the palette is defined globally... The screen's palette will be applied to all frames of the Animation. Since you are working in Lowres, you might as well use the full 32 colour palette.

Thanks for that.

I've been using only 16 because I was hoping to use 16 colours for the environments and 16 for character animation.

Originally I was using HiRes, but when I moved over from Amiga Forever to my newly acquired A600 I found it couldn't handle it.

Well if you plan to use a 32 colour screen, then your animation also needs to be 32 colours and use an identical palette to the screen, even if you plan to separate the palette uses between the bobs and background.

Animation could of course be in 16 colours if it uses four bitplanes only. So animation could use the first 16 colours and background graphics last 16 colours.

This should open room for optimisations since 5th bitplane would always have all bits zeroed or all bits set.

He is using AMOS, There really isn't much room for optimization, and all gfx formats must be the same... :-D
