我正在尝试使用IntelliJ上的Processing和OpenKinect库来连接我的Kinect以将其用于手部检测,此代码适用于处理3,但出于某种原因,当我以正确的格式将其放在IntelliJ上时,我得到了这个错误:
用法:PApplet [options] [sketch args]参见Javadoc 对于PApplet进行解释。
这是我正在使用的两个类。

PApplet需要一些参数才能启动。你提供了那些吗?

为什么你有两个扩展PApplet
的课程?
99.99%的时间,您应该只有一个类扩展PApplet
。然后,您可以将该类的实例传递给其他类,以便调用Processing函数。
除非你有充分的理由将PApplet
延长两次,否则你应该只延长一次。
为什么没有main()
方法?
如果您没有从Processing编辑器运行它,那么您需要编写自己的main()
方法来启动代码。在main()
方法中,您需要调用PApplet.main("YourSketchClassNameHere")
函数告诉Processing启动草图。
