I am making a gun mod in which you right click or left click and you will aim your gun but in the events and messages their is in a crash i have read in the crash report that it is the holding gun  fault anyway here is the code.

crash report

http://pastebin.com/6wAD7k4d

holding gun code

http://pastebin.com/aAbuR5zN

example? and when i right click there is a fatal error

You can't do this:

heldItem.stackTagCompound.getInteger("zoomed")

Without 1st checking if ItemStack has NBT. Default is NULL. Item only has NBT if you assign one.

 

Btw - you know about IExtendedEntityProperties right? Holding data in IEEP would be better (considering you need to know if player is aiming) than in ItemStack, just saying.

cant really clarify when i right click with the item i get the error

DO THE NULL CHECK!

 

As to other stuff:

You know that you can use InputEvent.KeyInputEvent and do all that you are doing in ClientTickEvent, just more efficient.

Also:

MinecraftForgeClient.registerItemRenderer(Mitems.g17, new Renderg17Aim());

WHAT THE HELL. Registering stuff happens ONLY in Mod#init() !!! Make ONE renderer with two cases.

3rd:

message.value = 2;

What's the point of this?

4th:

      EntityPlayer player = ctx.getServerHandler().playerEntity;
      EntityPlayerMP playermp = ctx.getServerHandler().playerEntity;

Why?

 

Bro, there is so much bad coding in there I can't comprehend it!

ItemStack#stackTagCompound can be null.

 

you are still not checking for the tag compouind beeing null
