Time.frameCount

Description

已经过的总帧数（只读）。

using UnityEngine;

public class Example : MonoBehaviour
{
    // Makes sure that RecalculateValue only performs
    // some operations once per frame and no more.
    static private int lastRecalculation = -1;

    static void RecalculateValue()
    {
        if (lastRecalculation == Time.frameCount)
            return;
        //  ProcessData.AndDoSomeCalculations();
    }
}

注意：所有 Awake 函数完成后，frameCount 就会启动。在 Awake 函数期间，frameCount 值是未定义的。
