Unity 显示FPS

直接绑定到Main Camera

using UnityEngine;
using System.Collections;

public class ShowFPS_OnGUI : MonoBehaviour
{

public float fpsMeasuringDelta = 2.0f;

private float timePassed;
private int m_FrameCount = 0;
private float m_FPS = 0.0f;

private void Start()
{
    timePassed = 0.0f;
}

private void Update()
{
    m_FrameCount = m_FrameCount + 1;
    timePassed = timePassed + Time.deltaTime;

    if (timePassed > fpsMeasuringDelta)
    {
        m_FPS = m_FrameCount / timePassed;

        timePassed = 0.0f;
        m_FrameCount = 0;
    }
}

private void OnGUI()
{
    GUIStyle bb = new GUIStyle();
    bb.normal.background = null;    //这是设置背景填充的
    bb.normal.textColor = new Color(1.0f, 0.5f, 0.0f);   //设置字体颜色的
    bb.fontSize = 40;       //当然，这是字体大小

    //居中显示FPS
    GUI.Label(new Rect((Screen.width/2)-40, 0, 200, 200), "FPS: " + m_FPS, bb);
}
