【Unity代码片段】Unity在Unity中显示帧率

在Unity中显示帧率
1.将脚本挂在于一个物体，
2.为FPS赋值一个UnityEngine.UI.Text text运行即可
FrameUpdata是帧数的在UI上的更新速度。

using UnityEngine;
using UnityEngine.UI;


    /// <summary>Simple FPS-Counter.</summary>
    [DisallowMultipleComponent]
    public class FPSDisplay : MonoBehaviour
    {
        #region Variables

        /// <summary>Text component to display the FPS.</summary>
        [Tooltip("Text component to display the FPS.")] public Text FPS;

        /// <summary>Update every set frame (default: 5).</summary>
        [Tooltip("Update every set frame (default: 5)."), Range(1, 300)] public int FrameUpdate = 5;

        private float deltaTime;
        private float elapsedTime;

        private float msec;
        private float fps;

        private const string wait = "<i>...calculating <b>FPS</b>...</i>";
        private const string red = "<color=#E57373><b>FPS: {0:0.}</b> ({1:0.0} ms)</color>";
        private const string orange = "<color=#FFB74D><b>FPS: {0:0.}</b> ({1:0.0} ms)</color>";
        private const string green = "<color=#81C784><b>FPS: {0:0.}</b> ({1:0.0} ms)</color>";
