Input.GetButton 获取按钮

static function GetButton (buttonName : string) : bool

Description描述

Returns true while the virtual button identified by buttonName is held down.

根据按钮名称返回true当对应的虚拟按钮被按住时。

Think auto fire - this will return true as long as the button is held down.

想象一下自动开火 - 如果按钮一直被按住此方法将永远返回true

Use this only when implementing action like events IE: shooting a weapon. Use Input.GetAxis for any kind of movement behaviour.

只有当执行像武器射击这样的事件时才可用此方法,Input.GetAxis适用于各种运动行为。

using UnityEngine;
using System.Collections;

public class example : 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;
		}
	}
}
// Instantiates a projectile every 0.5 seconds,
// if the Fire1 button (default is Ctrl) is pressed.
//实例化一个抛射每隔0.5秒
//如果Fire1按钮(默认Ctrl)被按下

var projectile : GameObject;
var fireRate : float = 0.5;
private var nextFire : float = 0.0;
function Update () {
	if (Input.GetButton ("Fire1") && Time.time > nextFire) {
		nextFire = Time.time + fireRate;
		var clone : GameObject =
		Instantiate(projectile, transform.position, transform.rotation) as GameObject;
	}
}
