Struct ForceField 

pub struct ForceField {
    pub kind: ForceFieldKind,
    pub region: Option<Aabb>,
    pub active: bool,
}

A force field applied to bodies inside a given AABB.

Fields

kind: ForceFieldKind

The kind of force applied.

region: Option<Aabb>

Region of influence. None = global.

active: bool

Whether this force field is active.
