It's a local multiplayer (splitscreen) game. There is no server. Are you  thinking of expanding the game to support online multiplayer?

[Foxface918]

 yes.

What will you have to send between the clients?

 

I think you should host it in listen (server is built into the game, and player 1 hosts for player 2)

Ok how would i do that

You would need to tell me exactly what you need to send between the clients, and how often you need to send them.

the movement data and health data

What is the size of these values, and how often will they be sent.

[Foxface918]

every frame and it is locked at 250 fps and the health is an 1 hit kill

So it's like:

boolean health

float xPosition

float yPosition

float rotation

[Foxface918]

int x

int y

no rotation

health is boolean

Ok. To send these packets you need to do something like this:

 

[Foxface918]

like what

 

[Guest]

ServerSocket listenSocket = new ServerSocket(8080);
Socket socket = listenSocket.accept();

DataInputStream dataIn = new DataInputStream(socket.getInputStream());

if (dataIn.readBool()) { System.out.println("Alive"); }
else { System.out.println("Dead"); }

socket.close()

Listen for boolean data (if player is alive)

[Guest]

Socket socket = new Socket(ip, 8080);

DataOutputStream out = new DataOutputStream(socket.getOutputStream());

if (Alive) { out.writeBool(true); }
else { out.writeBool(false); }

socket.close();

to send the alive data.

 

You should be able to modify this to send the rest.

[Foxface918]

ok but what about connecting the 2 clinents
