Input.GetAxis

public static float GetAxis(string axisName);  静态函数  返回值是个浮点数

Description  描述

Returns the value of the virtual axis identified by axisName.

返回由axisName标识的虚拟轴的值。

The value will be in the range -1...1 for keyboard and joystick input. If the axis is setup to be delta mouse movement, the mouse delta is multiplied by the axis sensitivity and the range is not -1...1.
对于键盘和操纵杆输入，该值的范围为-1 ... 1。如果轴设置为增量鼠标移动，则鼠标增量乘以轴灵敏度，范围不为-1 ... 1。
This is frame-rate independent; you do not need to be concerned about varying frame-rates when using this value.

这是帧率独立的;使用此值时，您不必担心变化的帧率。

using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour {    public float speed = 10.0F;    public float rotationSpeed = 100.0F;    void Update() {        float translation = Input.GetAxis("Vertical") * speed;        float rotation = Input.GetAxis("Horizontal") * rotationSpeed;        translation *= Time.deltaTime;        rotation *= Time.deltaTime;        transform.Translate(0, 0, translation);        transform.Rotate(0, rotation, 0);    }}

public class ExampleClass : MonoBehaviour {    public float horizontalSpeed = 2.0F;    public float verticalSpeed = 2.0F;    void Update() {        float h = horizontalSpeed * Input.GetAxis("Mouse X");        float v = verticalSpeed * Input.GetAxis("Mouse Y");        transform.Rotate(v, h, 0);    }}
