Input.GetAxisRaw 获取原始轴

static function GetAxisRaw (axisName : string) : float

Description描述

Returns the value of the virtual axis identified by axisName with no smoothing filtering applied.

通过坐标轴名称返回一个不使用平滑滤波器的虚拟坐标值。

The value will be in the range -1...1 for keyboard and joystick input. Since input is not smoothed, keyboard input will always be either -1, 0 or 1. This is useful if you want to do all smoothing of keyboard input processing yourself.

键盘和控制器取值范围在-1...1之间，此时输入没有使用平滑。键盘输入必然会是-1、0或1。这一点在你想自己处理键盘平滑输入时很实用。

		transform.Rotate(0, speed, 0);

}

function Update () {
	var speed : float = Input.GetAxisRaw("Horizontal") * Time.deltaTime;
	transform.Rotate (0, speed, 0);
