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 。

	// Rotate around our y-axis
	//以我们的y轴为中心旋转
	transform.Rotate (0, rotation, 0);
