Libraries Making Calls to User-Created Functions #35

I have a question about the interfacing of the "Fisica" library and "processing.py". I am trying to use the FContact class to detect the vertical component of the contact normal. According to the reference, you must implement the methods "contactStarted (FContact contact)", "contactPersisted (FContact contact)", and "contactedEnded (FContact contact)" in your applet in order to access method getNormalY (). These methods are supposedly called automatically when a contact is detected, such as the key event methods in processing. Please let me know if there is any way to get this to work with processing.py.

Unfortunately, there's no way to do this unless I ship processing.py with Fisica built in, since I'd have to make build-time reference to several fisica package classes, and then match those classes at runtime. I'm not at all opposed to the idea. I'll try to contact Fisica's author and discuss the idea with him.

Thank you for responding so quickly about my dilemma. In addition to my previous post, I currently use the majority of Fisica's classes in processing.py. without any issues. Fisica is a very nice rigid body simulation library and I know many people would enjoy the support via processing.py.

Just tp let you know, things are going slowly but steadily. I'm porting all of the fisica example programs to processing.py, and fixing bugs as I find them.

Thank you for letting me know and resolving this issue.

Fisica has been updated to make it compatible with processing.py.
