在用户按下由 buttonName
标识的虚拟按钮的帧期间返回 true。
您需要从 Update 函数调用该函数(因为每帧都会重置状态)。
在用户释放键并再次按键之前,它不会返回 true。
仅在实现武器开火事件等操作时,才使用该函数。\
对于任意类型的移动行为,请使用 Input.GetAxis。
编辑、设置或删除按钮及其名称(例如“Fire1”):
1.转到 Edit > Project Settings > Input 以调出 Input Manager。
2.单击它旁边的箭头,展开 Axis。这将显示当前按钮的列表。您可以使用其中一个作为“buttonName”参数。
3.展开列表中的某个项目后,可以访问和更改相关选项,例如按钮名称以及触发它的键、游戏杆或鼠标移动操作。
4.有关按钮的更多信息,请参阅输入管理器页面。
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public GameObject projectile; void Update() { if (Input.GetButtonDown("Fire1")) Instantiate(projectile, transform.position, transform.rotation); } }
