Le plateau + +### 2.1 La grille + +Le plateau est un damier avec des cases claires et sombres alternees.

Systeme de transfert + +### 4.1 Le principe + +Les colis se transmettent **automatiquement** entre entites adjacentes (4-connecte : haut, bas, gauche, droite). Le joueur ne gere pas les transferts — il gere l'espace. + +Les transferts se produisent entre : +- **Production → Piece** : la production donne a une piece adjacente sans colis +- **Piece → Piece** : une piece avec colis donne a une piece adjacente sans colis +- **Piece → Demande** : une piece avec colis compatible donne a une demande adjacente + +### 4.2 Quand le transfert a lieu + +Un transfert se produit quand, a la **fin d'un coup** (une fois que toutes les pieces ont bouge) : +- Une entite avec colis et une entite sans colis (ou une demande) sont sur des **cases adjacentes** (4-connecte) +- Le colis est compatible (la demande accepte ce type de cargaison) + +Le transfert est **instantane** : le colis passe d'une entite a l'autre entre deux coups. + +### 4.3 Priorite par statut social + +Quand plusieurs transferts sont possibles au meme point, le **statut social** determine l'ordre : + +**Regle de don** : parmi les pieces avec colis adjacentes a un meme receveur, celle de **statut le plus eleve donne en premier**. + +**Regle de reception** : parmi les pieces sans colis adjacentes a un meme donneur, celle de **statut le plus eleve recoit en premier**. + +``` +Hierarchie de statut social (proto) : + Tour 5 + Fou 3 + Cavalier 3 +``` + +**Exemple** : +``` + Tour (colis) ─adjacent─ case vide ─adjacent─ Cavalier (vide) + ─adjacent─ Tour (vide) +``` +La Tour avec colis donne. Deux receveurs possibles : Cavalier (3) et Tour (5). La Tour recoit (statut 5 > 3). + +### 4.4 Pourquoi c'est un outil de design + +Le statut social n'est pas une regle abstraite — c'est un **outil de routage** pour le joueur : + +- Aux croisements, le joueur choisit le TYPE de piece pour controler ou va le colis +- Une Tour "capte" un colis avant un Cavalier — le joueur met une Tour sur la route prioritaire +- Un Cavalier sur une route secondaire ne prend que les colis que personne d'autre ne veut + +Le joueur n'ecrit pas de logique conditionnelle. Il **compose sa flotte** pour que le flux aille ou il veut. + +### 4.5 Le puzzle d'espacement + +Les pieces qui ne doivent PAS interagir doivent etre **espacees d'au moins 2 cases**. Sinon un transfert involontaire se produit. + +``` +PROBLEME — deux chaines trop proches, les colis se melangent : + + ──Tour A──► ◄──Tour B── (chaine 1 : bois) + ──Tour C──► ◄──Tour D── (chaine 2 : pierre) + ↕ adjacentes = transfert involontaire ! + +SOLUTION — espacer les chaines : + + ──Tour A──► ◄──Tour B── (chaine 1) + . . . . . . . . (1 case d'ecart) + ──Tour C──► ◄──Tour D── (chaine 2) +``` + +Gerer l'espace sur le plateau pour eviter les interferences EST le puzzle. Le joueur doit router ses chaines en tenant compte des contraintes de mouvement (echecs) ET de l'espacement (logistique). + +--- + +## 5. Deroulement d'un coup + +### 5.1 Sequence d'un coup + +A chaque coup, dans cet ordre : + +``` +1. MOUVEMENT : toutes les pieces bougent simultanement + (chaque piece avance de Depart→Arrivee ou de Arrivee→Depart) + +2. DETECTION DE COLLISION : si deux pieces sont sur la meme case → erreur + +3. TRANSFERTS : tous les transferts automatiques se resolvent + (productions → pieces, pieces → pieces, pieces → demandes) + En respectant l'ordre de statut social + +4. PRODUCTION : les cases de production generent un colis + (si elles n'en ont pas deja un en attente) +``` + +### 5.2 Collisions + +Deux pieces ne peuvent pas occuper la meme case au meme coup. Si cela arrive : +- Les deux pieces clignotent en rouge +- La simulation se met en **pause** +- Le joueur doit reorganiser ses pieces (revenir en mode edition) + +Les collisions sont le signal que les chaines sont mal agencees.
