Resource Pack Creation Tutorial

This tutorial is on creating a resource pack on your desktop (at least the way I make mine)

First, create a folder on your desktop called whatever you name your pack. Then open that folder after naming it and create
a file called pack.txt. After the pack.txt is done, rename the RIGHT side of the decimal point from txt to mcmeta, unless you used the pre-made one above. This mcmeta file makes the pack work. HERE are pre-made mcmeta files.

Next create a new folder inside called assets, then inside that, for vanilla reource packs, a folder called minecraft. If you want to make a pack for a mod you need to make another folder named (modname). The actual modname of a mod can be found by extracting the mod into a folder form, it is the name of the first folder inside that is related to the usual modname(sometimes it is no different than the usual mod name).

So, for vanilla packs lets say you want to alter the bow texture. First inside the minecraft folder you made previously make folders inside each other in the following order: textures > items, or for armor it would be in: textures > models > armor. Inside the items folder place your new texture of the bow named, because it has to match the original item name, name it bow_pulling(0-2 of textures a bow has for drawing). The default bow image, when you are not firing an arrow, is bow_standby.

For editing a mods textures the method is similar. First lets say you want to change the texture of the ninja armor in the Custom Npcs mod to something else. Same, as before make a folder inside assets named customnpcs(that is the mods actual name minecraft recognizes), and make new folders inside as follows: textures > armor. Then place your textures you have made for your resource pack inside named, to match the original item name again, to: ninja_1 and ninja_2.

Btw Quick hint, in case you didn't know: the number 1 part of any skin in mods/packs has head, chest/arms, and feet texture,
and the number 2 part has just the legs part of the skin. I don't quite know why, it's just the way minecraft works.

So, now that you have re-textured the parts desired, go to the minecraft or (modname) folder. Inside this folder make a folder
named lang. Inside the lang folder you need to copy then paste the .lang file from minecraft or the mod to change item names
(btw en_ means it is the English version, in case it has more than one .lang) Find the item name desired and see how there's a = symbol after the name, then the name you see in-game? The RIGHT side of the = sign is what you rename your newly textured item to(say you have a lazer gun for bow now, you would call it: Laser Gun). Now some mods .langs are a bit different from others and it may be hard to find the item name you are looking for, but that
is something I'm not sure I can help with much.

Now that your pack has been made, you may place it in your resource packs folder of your .minecraft directory and select it
once in-game, I hope all goes well and this helps someone!
