I have created custom sound in 1.7.10 mod using sounds.json file and w.playsound function.  It works great for the player who activates the sound but the sound is not heard by other players on the server.  I was not able to figure out from searching how to get w.playsound to play for all players.  Can you take a look at this class and let me know what needs to be added for the sound to play for all players (within hearing distance, obviously).  Thanks very much.

World#playSound

does nothing on the server and plays the sound on the client.

World#playSoundAtEntity

,

World#playSoundToNearExcept

and

World#playSoundEffect

send a packet to the appropriate clients telling them to play the sound and do nothing on the client.

Many aspects of sound are counter intuitive (well, most of client-server architecture takes some experience to wrap one's head around).

 

Most of the sounds in the game are decided server-side and then sent to all listeners (world accesses) client-side. You'll see the calls bracketed by "!world.isRemote" (and you will want to do likewise).

 

It's an unusual sound that starts as a decision made client-side so that nobody else can hear it. Clicking on a game-control would be like that, not in the world, so applicable to only the player doing the clicking.

The way that i did it with my mod is to use the Block Event system. The Block Event system will send the block event to all clients that are near. You then play the sound on each client that receives it.

 

//When its turned on

private void setActive()
{		
	markDirty();
	if (theSound != "" && !soundloc.isNull())
	this.worldObj.addBlockEvent(xCoord, yCoord, zCoord, MCICraft.blockSound.getBlock(),0,0); //<---- Important line
}

 

//Code on the Block

@Override
public boolean onBlockEventReceived(World world, int x, int y, int z, int eventid, int eventparam)
    {
	TileEntity te = world.getTileEntity(x,y,z);

	if (!(te instanceof TileSound))
		return true;

	TileSound ts = (TileSound) te;

	if (ts.getSound() != "")
        world.playSoundEffect(ts.getX(),ts.getY(),ts.getZ(), ts.getSound(), ts.getFullVolume(), ts.getFullPitch()); //<-- Important Line

        return true;
    }

 

 

Note: While my code uses a TileEntity you don't need to use one (If you did you would have to send all the information to the clients tile entity using getDescriptionPacket() and onDataPacket()).

My problem is resolved by using w.playSoundEffect instead of w.playSound.  Simple as that.

 

Also, to be clear, it works equally well whether or not it is bracketed by !w.isRemote check.

Granted; playSoundEffect does nothing on the client side (the subclass of World instance passed in on the server-side is not the same as on client-side). Being paranoid (and wanting my code to remind me of what happens where), I still try to imitate vanilla code by bracketing my calls when I know what side they should run.
