I've noticed that you call CharModHelper.check_my_prototypes() from data.lua. You really should call it from data-final-fixes.lua instead! The idea is that other mods may change properties of the default character. For example, if there was an active character selector mod, and another mod that changed player reach was loaded after yours, the change won't be applied to your character when you call the function from data.lua..

I see, I'll do the changes and update the mod!

Edit: though it seems like I don't have "data-final-fixes.lua"
Does that mean I have to rename the data.lua or do I need to replace it entirely?

I think I got it
I looked at other mods and adapted my code to it, I hope it'll work with those changes made
Just need to get the corpse showing correctly again

Thank you, it's working now! Finally, I got the corpse. :-) By the way, did you know that you can make variations of the corpse (e.g., rotated versions)? I've just done this for the generic corpse of miniMAXIme:

corpse.pictures = {
  layers = {
    {
      filename = minime.IMG_PATH.."generic_corpse_variations.png",
      size = 256,
      shift = {0, 0},
      scale = 0.25,
      frame_count = 4,
      usage = "player",
    },
    {
      filename = minime.IMG_PATH.."generic_corpse_variations_mask.png",
      size = 256,
      shift = {0, 0},
      scale = 0.25,
      frame_count = 4,
      usage = "player",
      apply_runtime_tint = true,
    },
  }
}

This should be used for all characters, whatever their armor. The source image measures 1024x256, so each of the 4 frames has size = 256. Just in case you have nothing better to do … :-D

Ooooh
I'll keep that in mind if I feel like adding that, which I might do!
So it's like just another sprite sheet then?

Not quite sure if you can use a sprite sheet with >1 rows, but basically yes.

Oh, I think I get it now
I'll look into that in the next couple of days and see if I can get it working
Could also take the time to actually add corpse variations for each armour level too

Nice. :-)
