Input.GetKey

描述

Returns true while the user holds down the key identified by name. Think auto fire.

有关键标识符的列表，请参阅输入管理器。 处理输入时，建议改用 Input.GetAxis 和 Input.GetButton，因为 这允许最终用户对键进行配置。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Update() {
        if (Input.GetKey("up"))
            print("up arrow key is held down");
        
        if (Input.GetKey("down"))
            print("down arrow key is held down");
        
    }
}

描述

在用户按下 key KeyCode 枚举参数标识的键时返回 true。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Update() {
        if (Input.GetKey(KeyCode.UpArrow))
            print("up arrow key is held down");
        
        if (Input.GetKey(KeyCode.DownArrow))
            print("down arrow key is held down");
        
    }
}
