Modification de la formule de dégâts Empty Modification de la formule de dégâts

le Mer 23 Juin 2010 - 14:07
Voilà, après quelques recherches, je suis plus ou moins parvenu à modifier la formule de dégâts de VX, que je partage avec vous car je suis certain que cela risque d'aider bon nombre de makers. Je vous préviens, je ne suis pas connaisseur et j'y suis vraiment allé à tâtons, mais ça a l'air de marcher.
Procédons par ordre :

I/ Présentation

La formule que je vous présente est la suivante :

Dégâts d'une attaque normale = Attaque de l'utilisateur - Défense de la cible

Dégâts d'un skill / objet = Attaque de l'utilisateur + Intelligence de l'utilisateur + Puissance du skill ou objet - Défense de la cible (+ Influence physique / magique si vous en mettez)

De plus, les dégâts critiques font à présent deux fois plus de dommages qu'en temps normal (c'était 3 fois avant). Bien entendu, si cela ne vous convient pas, c'est modifiable : rendez-vous ligne 652 de Game_Battler.

La formule d'origine était :

Dégâts d'une attaque normale = (Force de l'utilisateur x 4) - (Défense de la cible x 2)

Dégâts d'un skill / objet = (Force de l'utilisateur x 4 x Influence physique / 100) + (Intelligence de l'utilisateur x 2 x Influence Magique / 100) - (Défense de la cible x 2 x Influence physique / 100) - (Intelligence de la cible x Influence magique / 100)


Notez que la nouvelle formule est plus logique et surtout facilite les calculs pour la programmation de vos héros / monstres / skills / objets / armes / armures.


II/ Modification de la formule


La formule de dégâts se trouve dans le script Game_Battler, ligne 637. Je vous offre le script complet mais je vous montre tout de même les modifications apportées.

Dégâts standards (ligne 643) :
Code:
damage = attacker.atk * 4 - self.def * 2
à changer en :
Code:
damage = attacker.atk - self.def


Dégâts d'un skill / objet (ligne 667) :
Code:
damage = obj.base_damage                       
    if damage > 0                     
damage += user.atk * 4 * obj.atk_f / 100     
damage += user.spi * 2 * obj.spi_f / 100     
unless obj.ignore_defense                   
damage -= self.def * 2 * obj.atk_f / 100 
damage -= self.spi * 1 * obj.spi_f / 100
à changer en :
Code:
damage = obj.base_damage                     
    if damage > 0                     
damage += user.atk + obj.atk_f   
damage += user.spi + obj.spi_f     
unless obj.ignore_defense                   
damage -= self.def

III/ Script

Merci ^^
Je pense qu'une formule telle que celle-ci permettrait de faciliter la programmation d'un jeu, et puis ça permet pour ceux qui ne connaissent pas la formule de base de VX de l'apprendre^^ Même si je pense que celle-ci semble plus logique et adaptée.
