Cela fait longtemps que je n'ai pas utilisé Flash, alors je pense qu'il est préférable d'apprendre ActionScript 3. Cependant, j'ai travaillé sur un [tutoriel vidéo Flash] [1] et j'ai vraiment du mal à cusomise la mise en page pour mes propres besoins. J'ai déplacé la barre de progression de 13,9px vers la droite et de 55,8px vers la droite. J'ai également réduit la barre de progression à 176.9px. Le problème est quand je clique sur le scrubber il saute vers la droite par le 55.8px. Je sais que je dois écrire quelque part que l'épurateur devrait commencer à 55.8px mais chaque fois que j'essaye je finis par causer d'autres issues. Est-ce que quelqu'un pourrait jeter un coup d'oeil à mon code et suggérer ce que je dois changer.Flash Actionscript 3.0 Aide sur le lecteur vidéo
