Bonjour, j’ai essayé de faire une commande qui dans mon Overlay va changer un String mais côté Solo ça marche mais quand je suis sur mon serveur de test Internal Server Error
Je veux que quand j’exécute la commande ça va faire : OverlayMain.text = “test”;
AH ! Et le text je veux qu’il soit unique pour le joueur qui a exécuté la commande si non le text reste vide
Tu mets le code qui change l’ovelay dans la fonction onMessage de l’handler.
Cela serait peut-être plus pratique de le faire depuis un plugin avec l’API Spigot, car ce qui concerne les commandes c’est plus simple par un plugin
Oui mais je m’y connais que en Modding 
Pourtant faire une commande sur Spigot n’est pas compliqué, la workspace est très simple à créer, et après tu utilises la fonction onCommand. Regarde sur youtube il y a des tuto dessus 
Bonjour,
Les commandes sont exécutés sur le serveur, elles ne peuvent pas modifier le rendu du client comme ça.
Il faut soit utiliser un paquet, soit faire une commande client.
@robin4002 Mais ducoup comment c’est ça ma question xD (Je débute hein)
Pour les paquets il y a un tutoriel sur ce forum même.
Pour les commandes clients: https://www.minecraftforge.net/forum/topic/59139-adding-a-client-side-only-command/
@robin4002 Quand j’appui sur “/” sur mon serveur de test (avec ma commande dessus) mon jeu crash

Comme déjà dis, les commandes sont exécutes sur le serveur, elles ne peuvent pas modifier du contenu client, ou alors il faut un paquet.
Cela ne peut pas fonctionner comme ça …
Ou alors faut faire une commande client, et dans ce cas il te manque implements IClientCommand et il faut changer la façon de l’enregistrer (je t’ai déjà envoyé toutes les ressources qu’il faut …).
@robin4002 Oui mais le tutoriel apparament il est en 1.12 fin à partir de la 1.12, je dois rappeler que je suis en 1.7.10 ?
En effet. Pas sûr que les commandes clients existaient déjà en 1.7, va falloir vérifier.
Si ce n’est pas le cas il te faut forcement un paquet.
@robin4002 ça n’existe pas 
Tu pourrais me montrer comment faire un Paquet ?
Il y a tout ce qu’il faut dans ce tutoriel : https://www.minecraftforgefrance.fr/topic/1000/1-7-2-le-network/
@robin4002 Et ça je le met ou ? Et comment ? 
Il te manque une variable là … Regardes l’exemple.
