Hello again!

 

I just finished up my networking stuff, and I already have an error...

This is the code of the IMessage:

 

package ra.heroworkbrine.elementalenergy.networking;

import io.netty.buffer.ByteBuf;
import cpw.mods.fml.common.network.ByteBufUtils;
import cpw.mods.fml.common.network.simpleimpl.IMessage;

public class EEMessage implements IMessage {

public int m1;
public int m2;
public int m3;
public int m4;
public int m5;
public int m6;

public EEMessage() { }

public EEMessage(int m1, int m2, int m3, int m4, int m5, int m6) {
	this.m1 = m1;
	this.m2 = m2;
	this.m3 = m3;
	this.m4 = m4;
	this.m5 = m5;
	this.m6 = m6;
}

@Override
public void fromBytes(ByteBuf buf) {
	buf.writeInt(m1);
	buf.writeInt(m2);
	buf.writeInt(m3);
	buf.writeInt(m4);
	buf.writeInt(m5);
	buf.writeInt(m6);
}

@Override
public void toBytes(ByteBuf buf) {
	m1 = buf.readInt();
	m2 = buf.readInt();
	m3 = buf.readInt();
	m4 = buf.readInt();
	m5 = buf.readInt();
	m6 = buf.readInt();
}

}

 

 

I have no idea what this error means, btw...

Only the int m6 can be larger than 256, if the problem lies that the bytebuf can only store bytes

You are writing in fromBytes and reading in toBytes. That's not right.

How did I not see that? Wow!
