Can I use m_userPersistentData safely? (for my own data)

[drawtree]

Is the field prepared for user-supplied data?

You are going to have to specify which class that member is on in order to answer this question effectively. But in general it's been my experience that members or functions that edit members with the word "user" in it are not touched by bullet and are there for your convenience. I've currently using the "m_userObjectPointer" on collision objects to point to my actors.
