                        this.y = originalbuffer.readShort();
                        this.z = originalbuffer.readShort();

I have to do with Opcode4.
Or i made the wrong structure

Re: Help me please UDP3 EVENT Opcode 3 and 4
 

3 and 4 is a same. https://forum.zone-game.info/showpos...18&postcount=6

Re: Help me please UDP3 EVENT Opcode 3 and 4
 

When I get posX, posY, posZ, what do I need to do next?
I have no structure

Re: Help me please UDP3 EVENT Opcode 3 and 4
 

Send to all clients for them to see the actual position of a player. kappa

P.S. Before this you need to check player's position data and speed of movement to switch off possibility of teleportation and speedhack and for lag compensation.

Re: Help me please UDP3 EVENT Opcode 3 and 4
 

I do not know how to send.

I need a structured way to send value to the client.

Re: Help me please UDP3 EVENT Opcode 3 and 4
 

@PROGRAMMATOR Send to all clients where Opcode ?
help me please
