Hi, I have a server crash problem due to my custom Key Handler class (NoDefFound). I have tried many things that dont seem to work: I tried registering it through KeyBindingRegistry and tried TickRegistry. I also added @SideOnly(Side.Client) annotations over the keyhandler. Here is the key handler code

@SideOnly(Side.CLIENT)
static KeyBinding binding = new KeyBinding("Aura Screen", Keyboard.KEY_R);

public AlchemiconKeyHandler() {
	super(new KeyBinding[] { binding }, new boolean[] { false });
}

@Override
public String getLabel() {
	return "mykeybindings";
}

@Override
public void keyDown(EnumSet<TickType> types, KeyBinding kb,
		boolean tickEnd, boolean isRepeat) {

	if (Minecraft.getMinecraft().currentScreen == null && tickEnd
			&& Minecraft.getMinecraft().inGameHasFocus) {
		Packet250CustomPayload packet = new Packet250CustomPayload();
		packet.channel = "aura";
		PacketDispatcher.sendPacketToServer(packet);
	}
}

@Override
public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) {
}

@Override
public EnumSet<TickType> ticks() {
	return EnumSet.of(TickType.CLIENT);
} 

Thanks for any help

The full error report would be appreciated.

I dont think its needed, but il post it.  The NoDefCrash on the KeyHandler is because the KeyHandler is a client side class, not server, but even with the Side Annotations it still doesnt work.

The line on the KeyHandler is the initilization of the binding, and the load in the main class is for the KeyBindingRegistry.

KeyHandler should only be registered on client side.

Use KeyBindingRegistry.registerKeyHandler on your client proxy for example.

 

As a side note, Annotations are supposed to help finding issues, not fixing them.

Thats what I use under my Init. KeyBindingRegsitry.registerKeyHandler

Well....anyone?
