Le simulateur utilise pygame, pour l'installer :
pip install pygame
une fois fait, pour lancer le simulateur, executez le main.py en tant que script (Ca permet à Pyzo de lancer le script dans le bon dossier)
Comment l'utiliser :
Les touches :
PARTOUT :
ESPACE : Met en pause le jeu
C : Diminuer la fréquence de mise à jour des cellules
V : Augmenter la fréquence de mise à jour des cellules
Q : Quitter
Suppr : Effacer la grille
D : Activer le mode débogage (Affiche les compteurs des cellules à l'itération précédente)
M : Basculer en mode Clavier / Basculer en mode Souris
Mode Souris :
Clic gauche : Changer l'état de la cellule selectionnée (rester appuyé pour en changer plusieurs)
Clic droit / Clic molette (glisser) : Changer la zone visible de la grille
Molette vers le haut : Zoomer
Molette vers le bas : Dézoomer
Mode Clavier :
Touches directionnelles (Flèches) : Déplacer le pointeur (cadre jaune)
T : changer l'état de la cellule selectionnée
À propos :
La grille est infinie, et par défaut, le mode souris est activé. Le mode clavier est incomplet mais permet de faire des actions basique.
