Faire un objet pour faire spawn un mob
-
J’ai essayé ça :
public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ) { EntityFireDragon fireDragon = new EntityFireDragon(world); this.worldObj.spawnEntityInWorld(fireDragon); return false; }Mais quand j’utilise l’item, Minecraft crash et me dit qu’il y a une erreur à ça :
Dans ontItemUse :
this.worldObj.spawnEntityInWorld(fireDragon); -
What ?
Il n’y a pas de variable worldObj dans Item.java, je sais pas ce que tu fais, le monde est null c’est pour ça que ça crash.
Utilise ça :public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ) { EntityFireDragon fireDragon = new EntityFireDragon(world, x, y, z); world.spawnEntityInWorld(fireDragon); return false; } -
D’accord merci
(et pour le worldObj, je l’avais déclaré dans ma classe)EDIT : ça marche ! merci
DOUBLE EDIT : Ah non en fait… Le dragon spawn mais est invisible
et ne fait rien :(:(TRIPLE EDIT : Ah si, mais il spawn à 0, 0, 0 et ne bouge pas

Un peu d’aide s’il vous plaît

public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ) { if(!world.isRemote) { EntityFireDragon fireDragon = new EntityFireDragon(world, x, y, z); world.spawnEntityInWorld(fireDragon); return false; } }Comme ça ça devrait fonctionner. J’avais pas vu tes edit.

Ah d’accord
Merci !___
EDIT : Eclipse me met une erreur à la fonction pour me dire qu’il faut ajouter une valeur de retour (return).
Est-ce que si je met return true à la fin de la fonction ça marchera correctement ? -
Oups, mets comme ça :
public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ) { if(!world.isRemote) { EntityFireDragon fireDragon = new EntityFireDragon(world, x, y, z); world.spawnEntityInWorld(fireDragon); return true; } return false; } -
Ah d’accord merci :)___
EDIT : Petit problème : j’avais changé le constructeur de mon dragon pour que new EntityFireDragon(world, x, y ,z) ne me fasse pas d’erreur, mais l’entité ne fonctionne pas si le constructeur ne contient pas que ‘World world’.
Un peu d’aide ? -
Envoie la classe de ton dragon.

Ok, mais attention c’est un peu le bazar :

Utilise ça :
public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ) { if(!world.isRemote) { EntityFireDragon fireDragon = new EntityFireDragon(world); fireDragon.setPosition(x, y, z); world.spawnEntityInWorld(fireDragon); return true; } return false; }Ou alors fait un nouveau constructeur dans la classe de ton mob :
public EntityFireDragon(World world, int x, int y, int z) { this(world); this.setPosition(x, y, z); } -
Le nouveau constructeur fait bugguer l’entité donc je prends l’option 1.
Merci

Résolu du coup ?

ça marche parfaitement, merci encore
