Changement d'apparence sur une Sphere
Bonjour,
j'ai réalisé une petite appilcation 3D où j'affiche juste une sphere.
Quand je veu modifier la couleur de cette sphere en utilisant la methode setAppearance(Appearance) à l'execution ca me donne l'exception"CapabilityNotSetException" car il faut la capabilités "ALLOw_APPEARANCE_WRITE".
J'ai pourtant appelé la methode setCapability(ENABLE_APPEARANCE_MODIFY) qui donne les capabilités "ALLOw_APPEARANCE_READ" et "ALLOw_APPEARANCE_WRITE" mais sa ne change rien.
Pouvez vous m'aidez svp, c'est tres important pour moi
