there is a problem with the x position you check in bounce

  • -a- pls make a variable like:
    var platlength=100;
  • -b- make the platform with:
    line(this.x, this.y,this.x+platlength, this.y);
  • -c- check the bounce with:
    if (this.x >= platforms[i].x && this.x <= platforms[i].x+platlength && …
