I am trying to get an answer on Stack Overflow towards this issue. So far, nobody was able to answer this question. I decided to ask here since this is a forum for Panda3D.
Full details are in the provided hyperlink. In short, I am trying to do character movement from the provided code example on Panda3D’s manual towards their Bullet Physics engine. I have gotten a world set up, but it throws me an error about worldNP. I have not went through the entire document, but a quick search indicates that worldNP is only dealt with their Bullet Physics engine.
