This can never be true. ItemStacks aren't null.

You didn't even show the code that is crashing.

It's mostly a redundancy check, if for some reason it is null

Pingun114 · October 6, 2019

Line 58: SimpleRpgTools.network.sendToServer(new MessageExtendedReachAttack(res.entityHit.getEntityId()));

Pingun114 · October 6, 2019

Hmm, I've gotten it to stop crashing, though I've run into a different problem.

FMLIndexedMessageCodec exception caught
io.netty.handler.codec.EncoderException: java.lang.RuntimeException: Undefined discriminator for message type crimson_twilight.simplerpgtools.common.util.MessageExtendedReachAttack in channel simplerpgtools

Does it have to do with:

public void init()
	{
		int packetId = 0;
		SimpleRpgTools.network.registerMessage(MessageExtendedReachAttack.Handler.class, MessageExtendedReachAttack.class, packetId++, Side.SERVER);
	}
