Detailed Description

template<class CC>
class MFM::Element_Boids< CC >

A clump-forming class. Goals:

Survive and operate in a DReg environment, recruiting Res to establish and maintain the clump.
Approximately but effectively regulate clump size even though the size will be larger than an event window radius.
Maintain 'clump identity' by a shared belief about the position of the center or centroid of the clump. Nearby clumps will not coalesce in calm conditions due to their separate identities.
An ability to maintain and (later) move the clump position.

Class: (C1) Name is Ball (C2) Type is 0xba11 (C3) State is BallState

Sets: (S1) BallState is { center, when }, with (S1.1) center, a TinyVec<3> — heading to believed center (S1.2) when, a u3 — events since last two+ point confirmation on center. — max value for 'when' means no confidence in 'center' (S2) BallInfo is { center, count, distance, nearus, adjemp }, with (S2.1) center, a Point — location of claimed Ball center (S2.2) count, a u8 — number of votes for that center (S2.3) distance, a u8 — distance to nearest-us voter for this center (S2.4) nearus, a Point — location of nearest-us voter for this center (S2.5) adjemp, a Point — location of Moore neighborhood empty nearest this center

(S3) Centers is Array[limit 3] of BallInfo (S4) Empties is Array[limit 7] of Point — Moore neighborhood empties

Actors: (A1) self, a Ball (A2) info, a Centers (A3) empties, an Empties (A4) i, an Index into info (A5) e, an Index into empties

Self check:

None

Perception:

Collect potential clump centers + exact match confirmation counts, for, say, up to three centers. Include self. Also for each potential clump, collect distance to nearest of that clump.
Also collect Moore neighborhood live empties

Reactions:

(R1) self.when = 0

(R2) Place(self), then (R3) Done

(R4) self.when = 0, then (R5) self.center += empties[e]-self, then (R6) self <=> empties[e], then (R7) Done

Thought:

— (1) If I'm part of a confirmed ball stay near center — (2)

(1) If info.length > 0: — At least one confirmed center

(1.1) If there exists i such that self.center info[i].center:

Do (R1), then

(1.1.1) Length(info[i].center) > 1: — We're not at center (1.1.1.1) There is an adjacent empty e closer than self to center Do (R5), (R6), then Done (1.1.1.2) — No closer empty Do (R2) then Done (1.1.2) MinDist to ball <= 1 (1.1.2.1) There is an adjacent empty e farther from ball but no farther than self from center Do (R5), (R6), then Done

Parameters

window The EventWindow describing the Event which is currently being executed.

Implements MFM::Element< CC >.
