Functions

ballistic_range

Caluculate range of a projectile being fired from initial_height with speed and only affected by gravity.

launch_velocity

Calculates a low and high angle for projectile to start at start_pos to hit target_pos with a given initial_velocity.

launch_velocity_lateral

Solve for arc with a fixed lateral speed. Vertical speed and gravity varies. This leads to a visually pleasing arc.
