J'ai trouvé un sujet dans lequel des utilisateurs ont fixé certains bugs des démos 3D de purebasic.
Je pense que l'exemple de ThirdPersonn.pb est vraiment meilleur tel que donné dans ce sujet :
http://www.purebasic.fr/english/viewtop ... 15&t=48108La démo fonctionne vraiment bien mieux, le personnage arrête ses animations lorsque l'on arrête d'appuyer sur les flèches, etc..
Bref, je pense qu'il serait judicieux de remplacer l'exemple thirdpersonn.pb par le code qu'ils ont corrigé.
Voici une copie (à placer dans le même dossier que celui où se trouve thirdpersonn.pb). je me suis permis de changer 2 ou 3 bricoles (ajout d'une light sans ombre et worldshadows en additive, modification du saut pour que ce soit un peu plus réaliste) :

A propos de cette démo,
Ar-S a écrit:
Encore quelques mois et tu vas nous faire un Pure Game Maker !
non, c'est juste un simple éditeur de level
. Ca permettra de créer/charger/modifier/enregistrer des niveaux de jeux, mais on devra faire tout le reste du code quand même
(gameplay, interaction pnj/player/mob, interaction player/objet, etc..).
Citation:
Ce jour là j'apporterai moult offrandes au pied de la statue dorée que j'aurai érigé en ton honneur
fais plutôt ça pour Fred, c'est lui qu'il faut remercier (et G-rom et tmyke pour la 3D aussi grandement
).
