I’m not that good at making videos, and neither is my computer. 🙂
Nevertheless, I made a step by step video for you.

The first time I didn’t think about the bug myself, which ignores screenplay until the next restart of the game. But after a manual game restart it worked. I’ve left this for you in the video so you can also see how to chase a bug.
You should be able to understand with the video how to build the function. In principle, I did the same thing there, what I described here in the tutorial. Only the name of the level is still “first”.
@You:
If you think this video is not that good, you also can help.
After you understood the method, you could make a better video for the community and post its link here. 🙂
