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”.
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. 🙂
