super((IItemHandler)tileentity, index, xPosition, yPosition); ton tile entity n’implement pas l’interface IItemHandler c’est pour ca que ta une castExcep

Reikenz

Donc je change quoi oui je débute donc je m’y connais pas trop

SpyMan

copier du code complexe sans connaitre c’est pas conseiller
implement ta class rajoute a la declaration de class
“implements IItemHandler”

Reikenz

Je met ma class en abstract ou je génère le code qu’il me dit ?

SpyMan

non faut pas la mettre en abstract gen le code
en gen le code ca va d’implementer les methods abstraites de l’interface

Et ensuite j’ai test sa crash:

le crash log stp
il faut remplir les methods que ta implementées maintenant je peu pas d’aider je connais pas l’api de ironbackpacks
regarde selon les backpacks du mod comment il a fait et qu’a t-il mit dans ces methods

je crois plutôt que tu devrait refaire un item avec gui fait par toi histoire d’au moins y comprendre un truc mdr car la tu galère comme pas possible
si tu fait ton propre code ca devrait être intensément moins dur déjà
