설명

Interface into the Input system.

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 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.

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

Mobile Devices:

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.

As a device moves, its accelerometer hardware reports linear acceleration changes along the three primary axes in three-dimensional space. You can use this data to detect both the current orientation of the device (relative to the ground) and any immediate changes to that orientation.

Acceleration along each axis is reported directly by the hardware as G-force values. A value of 1.0 represents a load of about +1g along a given axis while a value of -1.0 represents -1g. If you hold the device upright (with the home button at the bottom) in front of you, the X axis is positive along the right, the Y axis is positive directly up, and the Z axis is positive pointing toward you.

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); } } }

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.
