Installation du cadre SLua
1. Téléchargez la dernière version depuis https://github.com/pangweiwei/slua/wiki et copiez tout le contenu du répertoire Assets dans le projet. Pour le produit final, vous pouvez supprimer des exemples, des documents et d'autres contenus. Si cela est en phase de développement, cela n’a pas d’importance.
2. Attendez que l'unité soit compilée. Si tout se passe bien, le menu SLua apparaîtra. Cliquez sur la commande All->Make dans le menu SLua pour générer manuellement le fichier d'interface U3d pour la version actuelle.
3. Chaque fois que vous mettez à jour la version SLua, n'oubliez pas All->Clear, puis All->Make, sinon il risque de ne pas fonctionner correctement.
