Function attractionForce

attractionForce(
    attractors: readonly ForceAffected[],
    gravity: number,
    distanceRange?: { max?: number; min?: number },
): (attractee: ForceAffected) => ForceAffected
For a given set of attractors, returns a function that a sets acceleration of attractee. Keep note though that this bakes-in the values of the attractor, it won't reflect changes to their state. For dynamic attractors, it might be easier to use computeAttractionForce.
Parameters
- attractors: readonly ForceAffected[]
- gravity: number
- distanceRange: { max?: number; min?: number } = {}
Returns (attractee: ForceAffected) => ForceAffected
Example: Force
```
const f = Forces.attractionForce(sun, gravity);
earth = Forces.apply(earth, f);
```
Example: Everything mutually attracted
```
// Create a force with all things as attractors.
const f = Forces.attractionForce(things, gravity);
// Apply force to all things.
// The function returned by attractionForce will automatically ignore self-attraction
things = things.map(a => Forces.apply(a, f));
```
