Struct ProgradeDirection 

pub struct ProgradeDirection {
    pub fallback_axis: Vec3,
}

Passive gravity-turn orientation: thrust follows the current velocity vector. At rest (or at an exact apex with zero horizontal speed) the fallback axis is used until there is a measurable direction of motion.

Fields

fallback_axis: Vec3

Axis used while the speed is too small to define a direction.

Implementations

impl ProgradeDirection

pub fn new(fallback_axis: Vec3) -> Self

Fall back to this axis while stationary. Typically the launch direction.
