npc_ai_level_scale (Mob Prend le level de la cible) - Stitch - 16/06/2020

[Image: Stitch_npc_ai_level_scale.jpg]Stitch_npc_ai_level_scale.cpp


Ceci est mon premier essai de script d'AI de mob , merci de votre compréhension ^^

Ces Scripts permettent a un mob de prendre le level de sa cible a l'agro et d'avoir une AI générique en fonction de son role : Cast , Mélée ou Heal.
Pour vos zones customs ceux ci permettent donc de faire une zone adaptable du level 1 au level 100. 

Bon jeu a vous [Image: smile.gif]



Installation du script : 

Citation :
  1. Copier le fichier Stitch_npc_ai_level_scale.cpp dans les sources de votre core : \src\server\scripts\Custom
  2. Éditez le fichier custom_script_loader.cpp dans ce même dossier 
  3. Relancer Cmake puis recompilez votre core.
  4. Editez le creature_template de votre pnj et renseignez le ScriptName avec :
  • Stitch_npc_ai_level_scale_caster pour un mob qui attaque a distance comme un mage ou un chasseur
  • Stitch_npc_ai_level_scale_melee pour un mob qui attaque au contact comme un guerrier
  • Stitch_npc_ai_level_scale_heal pour un mob qui attaque a distance et ce soigne ou soigne ces alliés comme un pretre ou un chaman
A noter :
  • Le caster lancera ses sorts jusqu'a une distance de 30m et bougera aléatoirement de 15m s'il est au contact de sa cible. S'il n'a plus de mana il ira combattre au corps a corps.
  • Le mélée lancera ses sorts uniquement s'il est au contact
  • Le heal ce comportera comme le caster sauf qu'il a la possibilité de ce heal ou de heal un allié. En priorité il ce heal puis un allié et enfin il lancera un sort de degat. Celui ci possède un petit bonus de heal sur le caster.




Editer custom_script_loader.cpp comme ci dessous :
Code :
// This is where scripts' loading functions should be declared:
void AddSC_Stitch_npc_ai_level_scale();    

// The name of this function should match:
// void Add${NameOfDirectory}Scripts()
void AddCustomScripts()
{
        AddSC_Stitch_npc_ai_level_scale();
}





Editez la table creature_template :
Citation :Renseigner ScriptName avec Stitch_npc_ai_level_scale_caster , Stitch_npc_ai_level_scale_melee ou Stitch_npc_ai_level_scale_heal  en fonction du role .

Renseigner les spellx comme ci dessous
  • spell1 : Buff sur le caster a l'agro
  • spell2 : Sort sur la cible a l'agro
  • spell3 : Le sort utilisé sur la cible en combat ( chaque 2 a 3s environ)
  • spell4 : Le sort qui inflige des dégâts dans le temps utilisé sur la cible en combat ( chaque 10 a 15s environ)
  • spell5 : Le sort pour ce soigner ou soigner un alliés dans les 30m
Optionnel : Il est possible de jouer sur le cooldown par `BaseAttackTime` et `RangeAttackTime`

Exemple : 
UPDATE `creature_template` SET `ScriptName` = 'Stitch_npc_ai_level_scale_heal',`AIName` = '' WHERE (entry = 15000320);
UPDATE `creature_template` SET `spell1` = 974,`spell2` = 57994,`spell3` = 9532, `spell4` = 8056, `spell5` = 77472,`BaseAttackTime` = 3000,`RangeAttackTime` = 3000 WHERE (entry = 15000320);

Il est a noter qu'avant l'agro du mob et donc son adaptation au level de l'agresseur , la différence de level peut être énorme . 
Le mob peut vous agro de loin si par exemple vous êtes level 10 et que le mob avant adaptation est level 100 par defaut au respawn.
Le core par défaut augmente la distance d'agro suivant la différence de level avec une limite de 25 level, il est possible de limiter cette différence en éditant \src\server\game\Entities\Creature\Creature.cpp comme ci dessous :
  • Recherchez // "The maximum Aggro Radius has a cap of 25 levels under. Example: A level 30 char has the same Aggro Radius of a level 5 char on a level 60 mob."
  • Remplacez 
Citation :if (leveldif < - 25)
  leveldif = -25;

par

if (leveldif < -10) 
leveldif = -10;

EDIT : Ce test existe une seconde fois dans le meme fichier , recherchez donc if (leveldif < - 25)
