public static bool GetButton (string buttonName);

参数

buttonName 按钮名称,例如 Jump。

返回

bool 当按下并且未释放轴时,返回 true。

描述

当按住 buttonName 标识的虚拟按钮时,返回 true。

Think auto fire - this will return true as long as the button is held down. Use this only when implementing events that trigger an action, eg, shooting a weapon. The buttonName argument will normally be one of the names in InputManager such as Jump or Fire1. GetButton will return to false when it is released.

Use GetAxis for input that controls continuous movement.

// Instantiates a projectile every 0.5 seconds,
// if the Fire1 button (default is Ctrl) is pressed.

using UnityEngine; using System.Collections;

public class ExampleClass : MonoBehaviour { public GameObject projectile; public float fireDelta = 0.5F;

private float nextFire = 0.5F; private GameObject newProjectile; private float myTime = 0.0F;

void Update() { myTime = myTime + Time.deltaTime;

if (Input.GetButton("Fire1") && myTime > nextFire) { nextFire = myTime + fireDelta; newProjectile = Instantiate(projectile, transform.position, transform.rotation) as GameObject;

// create code here that animates the newProjectile

nextFire = nextFire - myTime; myTime = 0.0F; } } }
