[RPG-MAKER.FR] Oniromancie: tout l'univers de RPG Maker en français

Salut alors je comprend pas ce qui se passe parce que j'utilise moi aussi ce script sur un projet et tout fonctionne à merveille.

Alors pour commencer lorsque tu fais une demande d'aide sur un script le mieux c'est de donner le message d'erreur en entier (le top c'est de screen l'écran où tu as le message d'erreur).

Là j'imagine que ça doit être un truc du genre undefined method xx for nil:nil class

#Basic Quest System v1.3e
#----------#
#Features: Quests! What more can you say.
#
#Usage:   Set up your quests and away you go!
#        Script calls:
#         accept_quest(:questid)     - force quest accept
#         ask_accept(:questid)       - open quest acceptance window
#         abandon_quest(:questid)    - force quest abandon
#         turnin_quest(:questid)     - force quest turnin
#         fail_quest(:questid)       - force abandon with ME
#         ask_turnin(:questid)       - open quest complete window
#
#       adv_obj(:questid, :objectiveid, value)   - changes obj by value
#       set_obj(:questid, :objectiveid, value)   - sets obj to value
#       obj(:questid, :objectiveid)              - gets obj value
#       hide_obj(:questid, :objectiveid)         - hides objective
#       show_obj(:questid, :objectiveid)         - shows objective
#
#     $game_quests[:questid].accepted?     - true if quest is accepted
#     $game_quests[:questid].completed?    - true if quest is completed
#     $game_quests[:questid].turned_in?     - true if quest is turned in
#
# Examples:
#  The obj function can be used in conditional branches to check progress
#   of certain objectives. Example.
#    #Checking if :obj3 of :quest89 is greater than 3:
#     obj(:quest89, :obj3) > 3

voilà le code que moi j'utilise, j'y ais rajouté quelques quêtes pour les besoins de mon projet et tout les messages sont traduits en français. après je pense que le souci doit venir de la manière dont tu appelles tes quêtes :

par exemple pour cette quête ci dans le script :

    #Main Quest 3
  DETAILS[:questid003] = {
    :name => "L'académie",
    :abandonable => false,
    :level => 0,}
  DESCRIPTIONS[:questid003] = {
    :qgiver_name => "Gérant de la plantation",
    :location => "Bhamuta",
    :desc => "Livrer le colis à l'intendant
de l'académie draconique" }
  OBJECTIVES[:questid003] = {
    :obj1 => ["Livrer le colis à l'académie",1] }
  REWARDS[:questid003] = {}

j'utilise la commande script dans un évènement et je met ça dedans :

accept_quest(:questid003)

ainsi la quête s'ajoute automatiquement à la liste si j'avais voulu qu'on demande l'avis du joueur j'aurais mis :

ask_accept(:questid003)

Pour abandonner la quête (parfois une quête peut en remplacer une autre pour les besoins du scénario donc cette commande peut être utile):

abandon_quest(:questid003)

Pour valider la quête sans demander l'avis du joueur (généralement lorsqu'il n'y a aucun objet à fournir pour la quête j'utilise cette commande) :

turnin_quest(:questid003)

Pour demander au joueur si il veut ou non valider la quête :

ask_turnin(:questid003)

Dans le cas où la quête peut être échouée et si c'est le cas tu utilise cette commande :

fail_quest(:questid003)

Le script n' est pas forcément évident pour quelqu'un qui ne s'y connait pas en script surtout pour la configuration des quêtes mais une fois que tu l'as mis d'aplomb c'est nickel.

Edit : Ah ouais j'avais modifié un peu le script pour que le quest_log ne soit visible que si on garde appuyée la touche Z du clavier ^^. Si tu veux modifier ça dis le moi je te remettrai ça comme il faut.
