openKinect + Fisica. movement

lionessfighter

Hello. Before I ask nothing, i mean 2 things. 1. My native language is Spanish and 2. I'm not a professional programmer, I'm learning. So please excuse my car for all the gramatical errors and programming errors or the messy code.

Ok, I want to make some "organisms", that move alone, and then when someone is closer to the kinect, can modify the movement of these "organisms" For this, I been using fisica library and openKinect library, but I can't move them with the data taken from the kinect.

this is my code

Thanks for any help.

Are you working on windows? If so I might recommend using the kinect pv2 library which will give you skeleton tracking. This way you could combine the user's body form with fisica. http://codigogenerativo.com/kinectpv2/

Thanks for the answer, but, I'm not working on windows. there's something similar to that for Mac? Equaly I'm going to see the examples, maybe there's something that can help me like reference. I've really tried various things with the fisica library but FBlob bring me problems.

Thanks equally for the answer.
