Guys for set Texture pack is ez but how i can check if player used this texture pack else kick the player. like this if(!player.getRecursePack().eq....){ //kick }
Not possible. EDIT: Note that it is actually possible, but not easy to implement, and certainly not foolproof either.
You simple CAN'T force a player to use an texture (or resource)pack. However, you can keep track, which player downloaded your texturepack. But if he changed it back to another isn't recognized by the server.
