Fixed bug with animations.

- Before, if you shoot and go to the main menu, then the traces of the bullets were not removed from the map. This was because the animation stopped updating and the time kept going forward. As a result, the system believed that the animations had already passed, although in reality they had not. Now animations are tied not to their own, but to the global time counter
