making own game loop

The way I am organizing my current setup, I would like the ability to call a function in panda that does everything that would normally happen during run(). Basically I want my own framework in which I can call panda to update itself. If the only way is to write my own update function, what things does panda call every frame?

If you look in panda3d/direct/src/showbase/, you will notice the following function:

    def restart(self):
        # __resetPrevTransform goes at the very beginning of the frame.
            self.__resetPrevTransform, 'resetPrevTransform', priority = -51)
        # give the dataLoop task a reasonably "early" priority,
        # so that it will get run before most tasks
        self.taskMgr.add(self.__dataLoop, 'dataLoop', priority = -50)
        # spawn the ivalLoop with a later priority, so that it will
        # run after most tasks, but before igLoop.
        self.taskMgr.add(self.__ivalLoop, 'ivalLoop', priority = 20)
        # make the collisionLoop task run before igLoop,
        # but leave enough room for the app to insert tasks
        # between collisionLoop and igLoop
        self.taskMgr.add(self.__collisionLoop, 'collisionLoop', priority = 30)
        # do the shadowCollisionLoop after the collisionLoop and
        # befor the igLoop:
            self.__shadowCollisionLoop, 'shadowCollisionLoop', priority = 45)
        # give the igLoop task a reasonably "late" priority,
        # so that it will get run after most tasks
        self.taskMgr.add(self.__igLoop, 'igLoop', priority = 50)
        # the audioLoop updates the positions of 3D sounds.
        # as such, it needs to run after the cull traversal in the igLoop.
        self.taskMgr.add(self.__audioLoop, 'audioLoop', priority = 60)

Look further in for the actual __xxLoop functions.

The manual describes the main tasks as following:

I think the function you’re looking for is taskMgr.step()
