How to perform an operation on the server side through the Event Handler?

ONLY this is supposed to be sent to the server, NOT the whole method.

Yea but from what I saw on the docs:

 

public class ModMessage implements IMessage
{
	public ModMessage()
	{
	}

	protected int code;

	public ModMessage(int code)
	{
		this.code = code;
	}

	@Override
	public void toBytes(ByteBuf buf)
	{
		buf.writeInt(code);
	}

	@Override
	public void fromBytes(ByteBuf buf)
	{
		code = buf.readInt();
	}
}

 

The only thing I send as a message to the server is an integer...? I didn't know how to cal a function with just an integer and all that code is what I came up with

For example:

public class PacketSpawnParticle extends LocationDoublePacket<PacketSpawnParticle>{

    private double dx, dy, dz;
    private int particleId;

    public PacketSpawnParticle(){}

    public PacketSpawnParticle(EnumParticleTypes particle, double x, double y, double z, double dx, double dy, double dz){
        super(x, y, z);
        particleId = particle.ordinal();
        this.dx = dx;
        this.dy = dy;
        this.dz = dz;
    }

    @Override
    public void toBytes(ByteBuf buffer){
        super.toBytes(buffer);
        buffer.writeInt(particleId);
        buffer.writeDouble(dx);
        buffer.writeDouble(dy);
        buffer.writeDouble(dz);
    }

    @Override
    public void fromBytes(ByteBuf buffer){
        super.fromBytes(buffer);
        particleId = buffer.readInt();
        dx = buffer.readDouble();
        dy = buffer.readDouble();
        dz = buffer.readDouble();
    }

    @Override
    public void handleClientSide(PacketSpawnParticle message, EntityPlayer player){
        player.worldObj.spawnParticle(EnumParticleTypes.values()[message.particleId], message.x, message.y, message.z, message.dx, message.dy, message.dz);
    }

    @Override
    public void handleServerSide(PacketSpawnParticle message, EntityPlayer player){}

}

    }

    @Override
    public void handleServerSide(PacketSpawnParticle message, EntityPlayer player){}

}

 

 

I still don't understand how I'm supposed to use a buffer to tell the server to run a function, at best I can use the buffer to indicate to the server what function to run...

 

EDIT: actually hold on I got an idea

I am not touching this thread with a ten foot pole.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I can relate. :P

@Greyscail, your code is very mixed between sides. I would see this documentation by Forge and this video by MineMaarten, both of which explain sides in detail. But please actually read the documentation and watch the video. When I only started modding it took me a good chunk of time and effort to understand sides.

 

I'm finished helping here!

Until next time!

you don't have to make that static though.

He's probably refering to the @Mod.EventByusSubscriber annotation, which can be used to register event handlers without calling MinecraftForge.EVENT_BUS.register. In that case, you have to make the @SubscribeEvent methods static.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.
