Unity FPS显示工具

使用非常简单，创建个空物体,添加FPSDisplay脚本，修改脚本参数,运行即可

代码

using UnityEngine;

/// <summary>
/// FPS显示工具
/// </summary>
public class FPSDisplay : MonoBehaviour
{
    
    
    [Header("是否显示")]
    public bool isShow = true;
    [Header("更新间隔")]
    public float updateInterval = 1f;
    [Header("字体大小")]
    public int fontSize = 42;
    [Header("字体颜色")]
    public Color fontColor = Color.white;
    [Header("距离边缘")]
    public int margin = 50;
    [Header("显示位置")]
    public TextAnchor alignment = TextAnchor.UpperLeft;

    private GUIStyle guiStyle;
    private Rect rect;
    private int frames;
    private float fps;
    private float lastInterval;

    void Start()
    {
    
    
        guiStyle = new GUIStyle();
        guiStyle.fontStyle = FontStyle.Bold;        //字体加粗
        guiStyle.fontSize = fontSize;               //字体大小
        guiStyle.normal.textColor = fontColor;      //字体颜色
        guiStyle.alignment = alignment;             //对其方式

        rect = new Rect(margin, margin, Screen.width - (margin * 2), Screen.height - (margin * 2));
        lastInterval = Time.realtimeSinceStartup;
        frames = 0;
        fps = 0.0f;
    }
    void Update()
    {
    
    
        ++frames;
        float timeNow = Time.realtimeSinceStartup;
        if (timeNow > lastInterval + updateInterval)
        {
    
    
            fps = frames / (timeNow - lastInterval);
            frames = 0;
            lastInterval = timeNow;
        }
    }
    void OnGUI()
    {
    
    
        if (!isShow) return;
        GUI.Label(rect, "FPS: " + fps.ToString("F2"), guiStyle);
    }
}

效果图，按需要修改代码或参数
