Ceci est mon premier jeu / projet Phaser 3 et je « suis encore assez nouveau dans Javascript, donc je suis sûr quil y a beaucoup de choses que je pourrais faire mieux. La première chose que je voudrais améliorer dans mon code est la performance. Ensuite, lefficacité et la lisibilité du code, mais les performances sont la priorité absolue.

Vos commentaires sont précieux même si vous navez aucune expérience avec PhaserJS. , car beaucoup de choses que je pourrais probablement faire mieux nont à voir quavec du Javascript pur.

Mon code JS:
