buttonName | 按钮名称,例如 Jump。 |
bool 当按下并且未释放轴时,返回 true。
当按住 buttonName
标识的虚拟按钮时,返回 true。
可以想想自动射击的场景 - 只要按住按钮,该函数就一直返回 true。
请只在实现触发操作的事件(例如武器开火)时使用该函数。
buttonName
参数通常为 InputManager 中的名称之一,
例如 Jump 或 Fire1。松开按钮时,GetButton 将返回 /false/。
**注意:**对于控制连续移动的输入,请使用 GetAxis。
// 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; } } }
