Problem converting procedural script to a class file

Hello,

I’ve unsuccessfully tried to convert a procedural script into a class file, there’s no (no more ) errors but the desired effect you can see in the original file doesn’t work ! I don’t see where I’ve been wrong so I hope someone can guide me through in my first attempt to create a class… I really want to learn to use classes instead of procedural scripts but I’m actually quite confused about the way to do it!

Thanks in advance for your help!
