Addon Ajouter un effet à un item moddé

[Deltaga7]

Bonjour, je suis actuellement en apprentissage dans les addons de Minecraft bedrock.
j'ai créé un speedstick et je voudrais lui assigné une vitesse lorsque le joueur le tien en main.
Je sais qu'il faut aller dans le fichier player.json et ajouter certain component mais je ne comprend pas tout.
Es-ce que quelqu'un pourrait m'éclairer sur le sujet.
PS: l'item speedstick apparait belle et bien dans le monde
