GUI: Set material constants, or multi-texturing?

[Domarius]

Just regarding this discussion here:

Pixel Art Palette Swapping

Ok I found the issue I think, it’s also a restriction of how the GUI system works, similar to the request to add a 2nd texture. in go.set() “…or a material constant” in gui.set() “…only these named properties identifiers are supported” So it is impossible to set the “palette” material constant of the shader even if you can set the material on the box gui node. Hopefully one of the devs could weigh in on which feature is easier to add - multi-textures or setting material constants? I think I…

For this “palette swapping” shader to work on GUI nodes, we need either;

• Support for multiple textures in GUI materials, or
• Support for setting material constants via gui.set()

Which of these is more likely to be in Defold sooner?

I understand if it may be seen as low priority - I can work around it by implementing part of my GUI in the game’s camera instead, using sprites, for the part that needs palette swapping.

We would like to spend as little time as possible working on the gui. I suggest that you focus on a work around using sprites.

No worries, thanks for the update - yeah I came up with a better way, just pre-exported one icon for each character in the various 8 colour palettes, so I can still use the GUI. I’ll try and design around scenarios that require palette shaders in the GUI.
