Method for finding client instance of server entity?

[Stephen_789]

I've been trying to get the server and client instances of an entity I've been working on synchronized properly. I'm using packets to send data from the server instance to the client, but I can't find a way to identify the entity on arrival. I tried entityID and UUID, but both seem to be different between the client and server instances. Any suggestions? thanks.

Use net.minecraft.entity.Entity#getEntityId. It should be same. If it doesn't help, show the synchronisation code.

[Stephen_789]

I had it print out the ID via this.getEntityId() when it spawns, and I got this:

 

75495 Spawning via Item... Client?false

75495 Sending... Client? false

75496 Spawning... Client?true

 

the only one I'm spawning is the top one, and the bottom one is client-side, so it's spawning properly, but it's entityID is different.

 

...wait...

this is really weird.

I guess it does work, but I had a few typos in my receiving code. So even though it wasn't showing a different ID, but it was working.

Well, thanks for helping. EntityId looks like the way to go.

 

WAIT A MINUTE

 

it's sending it to a client version of the entity, but I can't see it! it's invisible, or somewhere else!

 

here's the code that's run in my packetHandler when the IMessageHandler receives a message:

[embed=425,349]

 

public void clientReceiveString(String s1, MessageContext ctx) {

 

int md = s1.indexOf("/");

String s2 = s1.substring(0, md).trim();

String s3 = s1.substring(md+1).trim();

entityBiplane tP = null;

if (Minecraft.getMinecraft().theWorld.getEntityByID(Integer.valueOf(s2)) != null) if (Minecraft.getMinecraft().theWorld.getEntityByID(Integer.valueOf(s2)) instanceof entityBiplane) tP = (entityBiplane)Minecraft.getMinecraft().theWorld.getEntityByID(Integer.valueOf(s2));

 

if (tP != null) {

 

tP.decodePacket(s3);

 

}

 

}[/embed]

 

and this is what's called in entityBiplane:

[embed=425,349]public boolean decodePacket(String s1) {

 

System.out.printf(this.getEntityId()+" Received: "+s1+" Client? "+this.worldObj.isRemote+"\n");

return true;

}

return true;

this.seatPos.y = Double.valueOf(s3);

return true;

}

if (s2.contains("seatPosZ")) {

this.seatPos.z = Double.valueOf(s3);

return true;

}

 

int sx = Integer.valueOf(s2);

}
