前言

官方文档input system：链接: input system
安装部分：链接: unity xr interaction toolkit的安装（二）

一、xri default input actions

1.导入官方案例

需要导入官方案例：starter assets，方便学习
在这里插入图片描述

2.设置控制器绑定，如手柄、主/辅助按钮、操纵杆等

1.要设置控制器绑定，如左右手手柄、主/辅助按钮、操纵杆等，请双击：xri default input actions

在这里插入图片描述

2.获取左手xy键事件（右手ab同理）

选择顺序 xr controller–>xr controller (righthand)或者xr controller(lefthand)–>usage
