Input.GetAxis 获取轴
static function GetAxis (axisName : string) : float
Description描述
Returns the value of the virtual axis identified by axisName.
根据坐标轴名称返回虚拟坐标系中的值。
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.
使用控制器和键盘输入时此值范围在-1到1之间。如果坐标轴设置为鼠标运动增量,鼠标增量乘以坐标轴灵敏度的范围将不是-1到1 。
// A very simplistic car driving on the x-z plane.
// 一个十分简单的在x-z平面的驾车例子
var speed : float = 10.0;
var rotationSpeed : float = 100.0;
function Update () {
// Get the horizontal and vertical axis.
//获取横向和纵向坐标轴
// By default they are mapped to the arrow keys.
//默认情况下他们关联到方向键上
// The value is in the range -1 to 1
//值的范围是在-1到1之间
var translation : float = Input.GetAxis ("Vertical") * speed;
var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed;
// Make it move 10 meters per second instead of 10 meters per frame...
// 使它每帧移动10米变为每秒移动10米...
translation *= Time.deltaTime;
rotation *= Time.deltaTime;
// Move translation along the object's z-axis
//沿着z轴平移对象
transform.Translate (0, 0, translation);
// Rotate around our y-axis
//以我们的y轴为中心旋转
transform.Rotate (0, rotation, 0);
}
// Performs a mouse look.
//执行一个鼠标观察
var horizontalSpeed : float = 2.0;
var verticalSpeed : float = 2.0;
function Update () {
// Get the mouse delta. This is not in the range -1...1
//获取鼠标增量，范围不在-1...1
var h : float = horizontalSpeed * Input.GetAxis ("Mouse X");
var v : float = verticalSpeed * Input.GetAxis ("Mouse Y");
transform.Rotate (v, h, 0);
