[1.7.10]Keybind making entity spawn?

[Stefinus321]

So I got a working keybind, but i can't spawn any entities in it. What now? I got the idea of sending a packet, but i don't know what i need to send with it nor how i then actually need to make the entity spawn (I'm quite new to packets).

 

KeyHandler (it works, but what now?)

Ok i changed to the Simple Network Wrapper (way easier than the PacketPipelin one). And now, say i wan't to spawn a snowball, that what i tried did not work.

 

the onMessage (the package is send to the server, ofcourse.

 

 

        World world = ctx.getServerHandler().playerEntity.worldObj;

        EntitySnowball ball = new EntitySnowball(world);

       

        if(!world.isRemote)// just to make sure...

        {

        ctx.getServerHandler().playerEntity.worldObj.spawnEntityInWorld(ball);

                //...and see proof of it in game

                        ctx.getServerHandler().playerEntity.addChatComponentMessage(new ChatComponentText("World is NOT remote"));

        }

       

        // test i did

            ctx.getServerHandler().playerEntity.addChatComponentMessage(new ChatComponentText("Package recieved, guess it's working"));

            return null;

 

 

I guess this is not the way to do it.

Welp, i got it to work.

I needed to add EntityPlayer player = ctx.getServerHandler().playerEntity; and then EntitySnowball ball = new EntitySnowball(world, player);
