I know this may sound nooby, but I can't seem to be able to register an event listener without it erroring, I've done it before, but this one doesn't seem to work at all. I'm registering it on the client side as it's a rendering listener. My client proxy methods work fine, this is how I'm registering it:

@Override
public void init() {
	//KeyBindingRegistry.registerKeyBinding(new KeyBindingListener(KeyBindingListener.keyArray, KeyBindingListener.repeatings));

	//TickRegistry.registerTickHandler(new ClientTickHandler(), Side.CLIENT);

	//MinecraftForge.EVENT_BUS.register(new OnScreenGui());
	MinecraftForge.EVENT_BUS.register(new ClientListener()); // This one! It's exactly the same as the one above..
}

 

This is the working listener:

public class OnScreenGui extends Gui {

private Minecraft mc;

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

@ForgeSubscribe(priority = EventPriority.NORMAL)
public void onRender(RenderGameOverlayEvent event) {
	// My method for my screen 
}
}

 

And here's the broken one:

public class ClientListener {

@ForgeSubscribe(priority = EventPriority.NORMAL)
public void onItemRendered(RenderPlayerEvent event) {
	// My method again
}

private Object supportingMethod1(Object args) {
	// Supporting method
}

private Object supportingMethod2(Object args) {
	// Supporting method
}

 

the error is as follows:

Thanks for the reply, that'll save the casting as well
