Hi

How would I go about changing the player's skin (not using the Mojang servers of course)? I tried binding a pre-made skin during the RenderPlayerEvent.Pre but that seems to do absolutely nothing. Does anyone know how to achieve this without creating a new player model (seems like to much work considering I would probably write a new RenderPlayer class)? Thanks in advance!

If you want to do this using vanilla itself - you can.

Look deep into AbstractClientPlayer. Since 1.7 there is whole skin-caching system so idk how to work with it directly, but I did that in 1.6 (changed skin-downloading page). Difference between 1.6 and 1.7 is literally one thing - caching.

 

You will most likely need reflection to access skin fields. You can even change capes.

Thanks for the reply, @Ernio. I didn't have much time today earlier, but I took a quick look around in AbstractClientPlayer, RenderPlayer, and some of the methods in those pertaining to the player skin. The only time it returns a ResourceLocation locally (not downloaded) is when the player uses the default skin - Minecraft has to resort to the Steve / Alex player skin. Maybe I could find the method that returns true or false based on a custom skin and utilize reflection to return false there every time. Then I could again use reflection to change the method that grabs the Steve / Alex player skin and return my own ResourceLocation there. In theory, it might work, I'll try what I said and see if I can figure a solution. If someone has a better one, let me know. Thanks.
