[SpyMan]

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
