i am trying to detect to call by an id but since the player can change the id, I can't use a switch unless i made 512 different cases which i really hope i don't have to. Right now i have a way these methods

 

	public int getID()
    {
    	return ID;
    }

 

	public boolean isIDSame()
{
	NBTTagCompound var2 = new NBTTagCompound();
	int var1 = this.getID();
	if(var2.getInteger("id") == var1)
	{
		return true;
	}
	else
	{
		return false;
	}
}

the player is going to have an item which when they right click will call the method of the class by the classes id i made sure to call every method the same so it would be easier.

Your isIDSame() method makes no sense. You're creating a new, empty NBTTagCompound and then trying to get an integer out of it. The result of that is always going to be the default value of 0.

 

You're going to have to explain more clearly what you want to achieve. Are you trying to recognise an item belonging to a different mod? Or one of your own items whose ID can be changed in a config file? Something else?
