*The sound of padded feet running through a hallway can be heard stomping over head. But, it's followed by a what can only be described as a surgical table being thrown down a staircase with all it's tools and gizmos flying all over the place in a deadly symphony. It has it's charm, and musical merit, yes, but the misplaced squeak of a rubber chicken ruins the composition, as well as the image in your head. None the less, the victim of this misfortune is undaunted as they seem to have slammed, face first, into your closed door. You continue to listen, as you are now firmly distracted from your previous task, and you hear the sound of someone who hasn't trimmed they're nails in a couple weeks desperately claw at your door. Finally hitting their mark in the quest to grab the handle, the nob turns and a strange boy in a dinosaur costume bursts into your environment. The abomination tries to speak through heaving lungs. The lad's only maybe 3 feet tall and he's too exhausted and breathy to talk clearly, but your can see he's gesturing with a pointed finger up at the "Thread's Title". This continues for a good 78 seconds before his harsh gasping for air starts to become language.*
"Aye Fellas. Ayo! Fellas. I got a story, like a stupid story to tell ya's."
So I imagine the lot of you are here because you're like me, and you like to blow some time making texture packs. But sometimes you can't do things like you want to because, it's hard coded or impossible, and you just have to suck it up. Let Mojang daddy tell you how to live your life. But not today friends. Today I feel like I grabbed Microsoft's car keys and ran away with them before the windows 10 law enforcement agency caught up to me. My shame was great, but those brief moments while on the run, were joy.
Now I'm totally cool to admit, that yes. This knowledge I'm about to share might just be common, and that this independent discovery is one that's already been made before. That my Google search skills aren't up to snuff. And to be plain, it isn't even much of an achievement. But if you've read this far, we've already agreed to waste a fair bit of time together. So! let's get onto the meat...
There are a couple threads you can find around here and other places, referencing a "witherarmor.png" found within the minecraft/textures/models/armor folder from yesteryears. As we know, this texture is the shield the Wither uses when he becomes invulnerable to projectiles. But if you go searching for it in versions/XXX/XXX.jar you won't find it in the armor folder, nor any folder for that matter. It seems to not exist. It's probably just something they patched out as the development came closer to it's public release.
At this point in the game, I assumed then, that maybe the boys over at the minecraft coding factory just forgot about this file's visibility publicly. And that if I put an image file by the same name in the same location that it appeared in that one particular snapshot (sometime around the Christmas chests release) that I might get lucky and be able to alter the texture in my resource pack. But, if you try to modify this texture at the time of this posting you'll have no effect in game. The Wither maintains his yellow-banded-head-shield weirdness regardless.
For some reason, I decided not to give up at that failed experiment and thought... Well, maybe they just moved it. Now my odds weren't good 'cause, honestly the only consistency they seem to keep in their naming conventions and folder organization is that everything is lowercase. But AYE, stick the .png into the wither folder under minecraft/textures/entity/wither and see what happens. Cant hurt, right? So I ran the game again and the wither was still unaffected. But I had one more idea I thought I'd try before giving up on this gamble. Why not rename the file to "wither_armor.png". Makes sense to me, "wither_invulnerable.png" follows this format. And so does the charged creeper shield.
Pop it in and BOOM. It worked. (reference images bellow... he's blue now cause testing... Yeah, you get the idea, here.)
Now as I stated in the "humble paragraph". This isn't some huge triumph. But I got a thrill out of it. I put it all into a resource pack, with the vanilla texture ::HERE:: so other people can play with the wither's armor texture easily.
But yo yeah. Thanks for the read, fam. I'll let you get back to it.
