Hello,

 

I can't seem to call any ItemStack methods inside a RenderGameOverlayEvent. It always gives a NullPointerException and it points at the line where the ItemStack method is, but it doesn't exactly explain why. Could any of you guys help?

 

Class:

public class ArmourOverlay extends Gui{

private Minecraft mc = Minecraft.getMinecraft();

private EntityPlayer p = mc.thePlayer;

public ArmourOverlay(Minecraft mc){
	super();
	this.mc = mc;
}

@ForgeSubscribe(priority = EventPriority.NORMAL)
public void onArmourChange(RenderGameOverlayEvent e){
	if (e.type == ElementType.ARMOR){
		e.setCanceled(true);
		if (p.getCurrentArmor(1).itemID == 310){
			System.out.println("test");
		}
	}
}

}

 

Error:

java.lang.NullPointerException

because the player doesnt have anything equipped ?

I did a if (p,.getCurrentArmor() == null) to see if that would fix it, but I got the same NPE error.

(1) or () ?

 

 

edit:

 

not ==

 

 

!=

I just tried if (p.getCurrentArmor(1) != null), but still NPE error.

p (aka player) can be null too.
