Emulations of drone flight

Emulation of drone flight.
First the user using the mouse displays the control points, the territory to be covered, after all the points are displays (there may be a lot of points), the user presses Enter, the flight trajectory (white lines) is drawn, and the drone begins moving.
The entire flight is cyclic, i.e. from the last point of the route the drone returns to the first point.
If the drone does not have enough battery charging to cover the entire route, the drone returns to the starting point.
