To install an X-ray texture pack for the game "Minecraft," first download a texture pack and save it to your computer. Load the game and open the Texture Packs menu from the main menu, click the Open Texture Packs folder, copy the files into the folder and click Done.
"Minecraft" texture packs allow you to add custom visuals to the game that modify the way items appear on screen. An X-ray texture pack alters the appearance of all game world blocks by creating an X-ray effect that allows you to see through the blocks. Players commonly use these texture packs to expose the locations of ore and mineral blocks, though some packs also include other features. To install such a pack, visit sites such as Curse.com, ResourcePack.net and ResourcesPack.net and choose the appropriate files.
After downloading the texture pack, check the folder to make sure that it contains a file with the name Pack.txt; the game needs this file to make the texture pack work. Load the game and open the Texture Packs menu, which is either on the main menu page or the Options page. After launching the folder on your computer, copy the files without closing the game and wait for them to show up in the menu. Click Done and check the game for the new textures.
