My game is still unfinished. It use Tower of Hanoi game with Darts extansion. Darts sprite disk navigation works fine. After pressing B button, displayed trajectory and buttons control should transfere to another sprite. But the control does not pass, and the trajectories are displayed for two sprites. Help is needed here. This is at the end of the controller.B.onEvent event handler.

Found a parameter that turns off the trajectory - setTrace (false). It’s better now 🙂
