Sprites Using Index Colour Mode Changing Colours On Scroll

[ClaytonMT]

Hi,

Describe the bug
When using the script with an asesprite file that is using Colour Mode: Indexed, it changes the colours of the layer it is applied to.

To Reproduce
Colour Mode Indexed file, apply script to a coloured layer - the resulting frames (and original) are recoloured.

Expected behavior
Colour stays the same, background is given scrolling animation

After:

System Information (please complete the following information):

This is def not intended behavior, thank you for submitting this issue!

Would you be able to let me know which version of the tool and of which Aseprite version you are currently using?

Also if possible would you be able to send this .ase file so I could dig deeper in to this? Curious as to how the layers and/or colors are set up in your project! If not I will try and re-produce with the steps above to see if I can get it to happen!

Thank you!

Hi,

Thanks for the swift reply!

Sure:

Auto-Scroll v1.1.4
Aseprite v1.3.2-x64

I had to zip the file to upload it as it does not allow .ase.

run_try.zip

There were only 2 layers as this was meant to be a file where I test characters running. I removed the layer with the player character, and the issue persists. I uploaded the file with the background only (before script is applied).

Regards,
Clayton

This seems to be an index color mode issue. Everything works as intended when swaping to RGB color mode. Very strange! Also sorry for the delay on this @ClaytonMT I had some other obligations that have kept me from digging back in to this eariler!

As a work around and temporary fix would be flipping in to rgb color mode (via Sprite>Color Mode> RGB) performing the scroll then flipping back in to index mode!

Digging deeper in to why index mode is messing with things though.

EDIT: Ah I think I have found the issue actually! It has to do with how the tool copies the sprites over and uses a temp new sprite to perform the scroll with wrapping. It wasn't keeping your current color palette so what your seeing is your sprite entering the temp tab with a default palette (with less colors) then when the sprite goes back to the original it doesn't have the indexes set correctly any more and why it looks like the colors are in fact changing!

This whole system is very outdated and very much old code from when I had originally created the tool some few years ago. Granted this problem had never surfaced till recently. In v2.0 which I'm a bit in the middle of... well before the forementioned obligations, I was re-writing this part of the code anyhow as I need it to also work with a set selection instead of the full canvas.

Anyhow long story short I see the issue and I will try and patch it up if possible so you don't have to wait for the complete re-write version!

Great news! I was able to get this fixed on the update I currently have in the works.

Planning to work on a few other features this weekend and hope to try and push this out soon. I will close this issue once the update is public! Thanks again for reporting this @ClaytonMT !
