How is it arranged in shooters in terms of delays and synchronization?

In shooters, delays and synchronization play a critical role in ensuring smooth and fair gameplay. Key mechanisms:

• Client-server model with prediction: the client predicts the outcome of its actions locally to minimize perceived latency.
• Interpolation and extrapolation: for other players, the client interpolates or extrapolates positions to smooth movement when receiving delayed updates.
• Server authority: the server makes final decisions on the game state to prevent cheating.
• Lag compensation: the server accounts for players' delays, for example, when registering hits, to ensure fairness.

From a Go implementation perspective, goroutines and channels can be used to handle network messages and timers, providing asynchronous processing and minimizing delays. For example:

// Example of handling incoming packets with a timeout
func handlePackets(packetChan <-chan Packet) {
    for {
        select {
        case pkt := <-packetChan:
            processPacket(pkt)
        case <-time.After(50 * time.Millisecond):
            // Handle timeout, e.g., send a state update
            sendStateUpdate()
        }
    }
}

Thus, the architecture and algorithms are aimed at minimizing delays and synchronizing state between the client and server.
