Input

描述

访问输入系统的接口。

KeyCode maps to physical keys only if "Use Physical Keys" is enabled in Input Manager settings, otherwise it maps to layout and platform dependent key mapping. Starting from 2022.1 "Use Physical Keys" is enabled by default.

使用该类来读取传统游戏输入中设置的轴，以及访问移动设备上的多点触控/加速度计数据。

要读取轴，请将 Input.GetAxis 与以下默认轴之一配合使用： “Horizontal”和“Vertical”映射到游戏杆（D、D、D、D 和箭头键）。 “Mouse X”和“Mouse Y”映射到鼠标增量。 “Fire1”、“Fire2”、“Fire3”映射到 Cmd、Cmd、Cmd 键和三个鼠标或游戏杆按钮。 可以添加新输入轴。请参阅输入管理器以了解相关信息。

If you are using input for any kind of movement behaviour use Input.GetAxis. It gives you smoothed and configurable input that can be mapped to a keyboard, joystick or mouse. Use Input.GetButton for action-like events only. Do not use it for movement. Input.GetAxis will make the script code smaller and simpler.

Note: Input flags are not reset until Update. You should make all the Input calls in the Update Loop.

另请参阅：KeyCode，其中列出了所有的按键、鼠标和游戏杆选项。

**移动设备：**

iOS and Android devices are capable of tracking multiple fingers touching the screen simultaneously. You can access data on the status of each finger touching screen during the last frame by using the Input.touches property array.

设备移动时，其加速度计硬件将报告设备沿三维空间中的三个主轴的线性加速度变化。 您可以使用该数据检测设备的当前方向（相对于地面）以及该方向上的任何即时更改。

硬件将沿每个轴的加速度直接报告为重力值。 值 1.0 表示沿给定轴约 +1g 的荷载，值 -1.0 表示 -1g。 当将设备竖直握住（主按钮位于底部）举到您正前方时， 右侧为正 X 轴，上方为正 Y 轴，指向您的方向为正 Z 轴。

You can use the Input.acceleration property to get the accelerometer reading. You can also use the Input.deviceOrientation property to get a discrete evaluation of the device's orientation in three-dimensional space. Detecting a change in orientation can be useful if you want to create game behaviors when the user rotates the device to hold it differently.

Note that the accelerometer hardware can be polled more than once per frame. To access all accelerometer samples since the last frame, you can use the Input.accelerationEvents property array. This can be useful when reconstructing player motions, feeding acceleration data into a predictor, or implementing other precise motion analysis.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public void Update()
    {
        if (Input.GetButtonDown("Fire1"))
        {
            Debug.Log(Input.mousePosition);
        }
    }
}

该组件涉及将 UI 纹理和图像绘制到屏幕的 传统方法。应改用 UI 系统。此外， 这与 IMGUI 系统无关。
