JavaScript => public static var time: float;
C# => public static float time;

Description 描述

The time at the beginning of this frame (Read Only). This is the time in seconds since the start of the game.

以秒计算，从游戏开始的时间（只读）。也就是说，从游戏开始到到现在所用的时间。

Returns the same value if called multiple times in a single frame. When called from inside MonoBehaviour's FixedUpdate, returns fixedTime property.

如果在单帧调用多次，返回相同的值。当在MonoBehaviour的FixedUpdate里调用的时候，返回的是fixedTime属性。

JavaScript:

	// Instantiates a projectile off every 0.5 seconds,
	// if the Fire1 button (default is ctrl) is pressed.
 
	var projectile : GameObject;
	var fireRate = 0.5;
	private var nextFire = 0.0;
 
	function Update () {
		if (Input.GetButton ("Fire1") && Time.time > nextFire) {
			nextFire = Time.time + fireRate;
			var clone = Instantiate (projectile, transform.position, transform.rotation);
		}
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public GameObject projectile;
    public float fireRate = 0.5F;
    private float nextFire = 0.0F;
    void Update() {
        if (Input.GetButton("Fire1") && Time.time > nextFire) {
            nextFire = Time.time + fireRate;
            GameObject clone = Instantiate(projectile, transform.position, transform.rotation) as GameObject;
        }
    }
}
