Problème de collisions avec un dragon

[bin4r1s]

Bonjour,
J’ai créé un dragon, tout fonctionne parfaitement à par ça :
Le dragon ne cause pas de dommages en entrant en collision avec quelqu’un et ne l’expulse pas. Il peut aussi passer à travers les blocs, ce que je ne veux pas.

Classe :
EntityFireDragon :
