g.mu.Lock()
_, err := conn.Write([]byte(strconv.Itoa(g.firstPlayer.x) + "-" + strconv.Itoa(int(g.firstPlayer.y))))
g.mu.Unlock()I think this has to be: g.mu.Lock()
x, y := g.firstPlayer.x, g.firstPlayer.y
g.mu.Unlock()
_, err := conn.Write([]byte(strconv.Itoa(x) + "-" + strconv.Itoa(int(y))))to shorten the locking time |

If nothing is sent to servers as you said before, I think this is not related to Ebitengine. I don't know what you said is not working. Please insert printlns and tell me which is reached and which is not. |

I think I found a bug when it runs the conn.Write I print it what it is sending it is zero and in runner I adding a log and there it is printing an actual number. |

In the server.go file I do have a print statement when you exit the game the client disconnects and it does register that. package main
import (
"bufio"
"fmt"
"net"
)
var clients = make(map[net.Conn]bool)
var messages = make(chan string)
func main() {
listener, err := net.Listen("tcp", ":8080")
if err != nil {
fmt.Println("Error starting the server:", err)
return
}
defer listener.Close()
fmt.Println("Game server is running on :8080")
go broadcastMessages()
for {
conn, err := listener.Accept()
if err != nil {
fmt.Println("Error accepting connection:", err)
continue
}
clients[conn] = true
go handleClient(conn)
}
}
func broadcastMessages() {
for {
message := <-messages
for client := range clients {
_, err := client.Write([]byte(message))
fmt.Println(message)
if err != nil {
fmt.Println("Error writing to client:", err)
client.Close()
delete(clients, client)
}
}
}
}
func handleClient(client net.Conn) {
defer client.Close()
reader := bufio.NewReader(client)
for {
message, err := reader.ReadString('\n')
if err != nil {
fmt.Println("Client disconnected:", client.RemoteAddr())
delete(clients, client)
return
}
messages <- fmt.Sprintf("%s: %s", client.RemoteAddr(), message)
}
} |

When I send the x and y coords to the server because that client.go without Ebitengine does work. |

I think it may be a issue with Ebitengine stating that when I do a diff the only differences are the stuff related with my game. |

Sorry for the issue thanks for resolving with \n thanks Oh one minute when sending it just sends 0, 0 I printed out the coords in runner it gave me the actual coords but in updateNetwork and I print it just prints out 0, 0. |

So does the client always send 0,0 even though the first player position is not 0, 0? |

Yes that is correct I had to eat my food I apologize for the delay. |

\nis not sent in your game so the server waits for\nforever.
