1 1  The **ball physics model**'s main objective is to provide a point in time to the controller, when the ball is predicted to be hittable, in order to not let the ball fall into the drain.

24 -The controller calls the function //full_prediction// passing it two subsequent ball positions with timestamps. From these a ball trajectory is infered as described above.
25 -Along the trajectory future times  are stepwisetested for whether the corresponding predicted position is in the flipper range.
26 -Once a position inside the flipper range is found the search is contiunued both forwards and backwards in smaller steps in order to find a good enough estimate of the first and last possible time to hit the ball.
27 -If the trajectory does not intersect the flipper range within a certain prediction frame (see below "**Prediction parameters**") a value far enough into the future is returned, that will be overwritten by subsequent predictions.
27 +It systematically tests future times for if the corresponding predicted position is in the flipper range.

29 -With the current configuration the controller uses the middle point in time between the first and last possible time in order to be most positive to hit the ball.
30 -The computed velocity is also passed to the controller and used is some more advanced  tactical decisions like catching balls.
