Tutoriel [Guide] [MAJ 12/07/14]Créer un launcher pour 1.6.2/1.6.4 avec mods

[GhostShell]

Bonjour à tous, je viens de faire mon launcher, de régler qques soucis au lancement, mais la je bloque depuis un moment sur un problème, j'ai un soucis avec le PermGen size, je souhaite le mettre à 256Mo par défaut, c'est à dire que les utilisateurs n'aient pas à le changer eux même, j'ai beau chercher ou je dois changer le paramètre dans les sources , je ne trouve rien, je n'ai rien trouvé non plus sur google concernant ce point, ni sur cette discussion malheureusement ...
Donc si qqun a une idée ou le code à placer dans les sources java je suis preneur
Merci d'avance

 

[GhostShell]

J'ai fini par trouver la solution en "tâtonnant" un peut dans le code source !
Pour les intéressés, tout se passe dans Eclipse, il faut aller dans le fichier minecraft-launcher->src/main/java->net.minecraft.launcher->GameLauncher.java

recherchez ensuite la ligne :

final String defaultArgument = is32Bit ? "-Xmx512M" : "-Xmx1G";

et remplacez la par :

final String defaultArgument = is32Bit ? "-Xmx512M -XX:PermSize=256m" : "-Xmx1G -XX:PermSize=256m";

et voilà, plus besoin d'aller éditer les options du profile dans le launcher pour démarrer un modpack avec beaucoup de mods !

[Oromis]

Désolé pour le double post beug !!

 

[CreepsCharli]

Oromis: Vérifie bien dans ton dossier versions --> taversion dans le fichier json que ton lien vers le dossier maven est bien correct

"com.google.gson.stream.MalformedJsonException: Unterminated object at line 31 column 16"

 

[CreepsCharli]

/!\ Double - post dû à un beug mozilla, désolé :'3

 

[Oromis]

Bonjour, j'ai un problème de connexion sur les serveur multi 1.7, jai ce message qui s'affiche dans la console : GameProfile{id='null', name='nicecube'} (/127.0.0.1:63268) lost connection: Disconnected quelqu'un a une solution pour réglé ce problème ? Sinon super tuto ! Beau travail

 

[Kouki]

Bonjour,

J'ai un énorme problème et je pense que vous avez TOUS le même, car j'ai suivi le tuto à la lettre.

Mon launcher re-télécharge le .jar à CHAQUE lancement O_O et il télécharge d'autres fichiers aussi, car il met un très gros temps à se lancé par rapport à l'officiel, cependant il ne re-DL pas TOUTES les assets (ça dure bcp moins longtemps quand même).

Je trouve ça inutile de RE-DL à chaque fois, ça fait ralentir le joueur etc... une idée les gars ? Car là O_O
