Input

Description

访问输入系统的接口。

Use this class to read the axes set up in the Conventional Game Input, and to access multi-touch/accelerometer data on mobile devices.

To read an axis use Input.GetAxis with one of the following default axes: "Horizontal" and "Vertical" are mapped to joystick, A, W, S, D and the arrow keys. "Mouse X" and "Mouse Y" are mapped to the mouse delta. "Fire1", "Fire2" "Fire3" are mapped to Ctrl, Alt, Cmd keys and three mouse or joystick buttons. New input axes can be added. See Input Manager for this.

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 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 more small and simple.

Note also that the Input flags are not reset until Update. It is suggested you make all the Input calls in the Update Loop.

See Also: KeyCode which lists all of the key press, mouse and joystick options.

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 accessing 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 read 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 read 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);
        }
    }
}

This component relates to legacy methods for drawing UI textures and images to the screen. You should instead use UI system. This is also unrelated to the IMGUI system.
