Enum Drive 

pub enum Drive {
    None,
    Speed {
        speed: Value,
        multiplier: Value,
    },
    Acceleration {
        acceleration: Value,
        multiplier: Value,
    },
}

What drives a particle along its heading.

Variants

None

Nothing along the heading (only gravity and forces move it).

Speed

A speed (metres per second) along the current heading: speed times multiplier, each a function of the particle’s age.

Fields

speed: Value

multiplier: Value

Acceleration

An acceleration (metres per second squared) along the current heading, integrated into the speed: acceleration times multiplier.

Fields

acceleration: Value

multiplier: Value
