Unit team color support
WizzardMaker opened this issue · comments
Units are colored in according to their team color - Red team has red units
The game uses probably reserved palette offsets to control which pixel gets what shade of the team color
There are multiple palette offsets probably, as there appear to be more than 1 team color shade. The exporter currently interprets it as a solid black. Importing the file like its exported, results in missing team colors.
Upon testing with upscaled textures, I noticed random team colors being added to the character. The most likely cause is, that the new files used the full 253 possible colors, that the importer is willing to give. The team colors are maybe in the high range of that limit.
There appears to be 32 shades per team color. Each color is rgb565. Here are the palettes for each team color:

Here is a demo that rotates the colors every 100 ms for each team:
Looks like the palettes you gave me aren't 100% right, or at least not long enough. I don't know the exact starting point of the team color palette, but it looks like its at 192. Problem is, the image still has some missing colors, as there are palette references beyond 224 (192+32). I've seen values like 244 or 248
Red value is the palette index:
The resulting image, when using your provided palette swap
There are no more than these 32 colors. Swapping them while being ingame seems to be enough to correctly change the team of a unit (see the gif above). Maybe the game can somehow "stretch" a palette. I will have to do more research on that though.
It actually does not look like it is a palette problem. It looks more like the game does some interpolation that we are missing. The problematic pixels are only at edges. Maybe the pixels with values 244, 248 etc are "blended pixels" that blend with the upper, left, right or bottom pixel (or a combination of them).
Edit: Can you do one for the blue colored settler? I think it will be more obvious with that color if that is the case.
Yes you were totally right. There is a second set of 32 team colors that are combined to the palette. However this second set is different for every object. These object specific team color palettes are stored in the files of the gfx directory. I've seen some of them come from 20.p26.
The color information for the team seems to be after the normal color information in the palette file.
After the 256 colors of the normale image, there are 32 colors for each team in a palette file.
