ServerCallbackAttribute

Description

A Custom Attribute that can be added to member functions of NetworkBehaviour scripts, to make them only run on servers, but not generate warnings.

This custom attribute is the same as the [Server] custom attribute, except that it does not generate a warning in the console if called on a client. This is useful to avoid spamming the console for functions that will be invoked by the engine, such as Update() or physics callbacks.

using UnityEngine;
using UnityEngine.Networking;

public class Example : MonoBehaviour
{
    float regenTimer = 0;
    int heat = 100;

    [ServerCallback]
    void Update()
    {
        // heat dissipates over time
        if (Time.time > regenTimer)
        {
            if (heat > 1)
                heat -= 2;

            regenTimer = Time.time + 1.0f;
        }
    }
}
