用tuio处理

Question

嗨，我是处理新手，我正试图弄清楚如何使用标记而不是鼠标使球体从左向右移动。你能帮我吗？我可以使用标记拍摄，但我不能通过拍摄移动球体

“射击”是什么意思？

所以你有tuioClient并在setup（）中初始化它。这很好，因为只要你的草图收到TUIO消息，就会触发回调方法（addTuioObject，removeTuioObject，updateTuioObject，addTuioCursor，updateTuioCursor，removeTuioCursor，refresh）。

请记住，TUIO基于通过UDP传输的OSC。这意味着跟踪器（reactivision＆amp; co）必须发送到草图正在监听的IP和端口。如果两者都在同一台机器上，请使用127.0.0.1和端口3333（默认）。 看看这些例子。您将在处理“IDE”中找到它们点击： “文件 - ＆gt;示例” 并导航到 “贡献的图书馆 - ＆gt; TUIO”
