如果要Unity PS4的左右两摇杆，那么需要配置好你的Input的Name, Type, Axis, Joy Num

Name:你自己定
Type:Joystick Axis
Axis:查看下表
Joy Num:自己定用哪个

然后代码中Input.GetAxis(“NameHere”)就可以了

如下两个图：

Input设置

代码调用

那么这个Move_1的就是手柄1(Joystick 1)的左摇杆的垂直值了
水平值得可添加一个Axis改为：X axis的就好了

Axis 表

PS4手柄部位	轴名(Axis)	值范围
Left Stick X-Axis(水平)	X Axis	-1.0 ~ 1.0
Left Stick Y-Axis(垂直)	Y Axis	-1.0 ~ 1.0
Right Stick X-Axis(水平)	3rd Axis	-1.0 ~ 1.0
Right Stick Y-Axis(垂直)	6th Axis	-1.0 ~ 1.0

之前查了好久都不知道是哪个轴，蛋疼，还好下面的References中的国外小哥分享了
