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

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

It doesn't have to be integers. It can be booleans and other values...

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){}

}

}

 

 

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 gotta go to sleep, I'll help more tomorrow!

Try to figure it out while I'm gone!

I'll strap this thread to a ten foot pole and touch you with it

I can relate.

@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!

Why the static? Explain.

because you need for the @mod.eventSubscriber

ExampleMod.INSTANCE.registerMessage(ModMessageHandler.class, ModMessage.class, ExampleMod.id++, Side.SERVER);

DONT do that in the event handler

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.

When should I do it then?

[loordgek]

in FMLPreInitializationEvent
