Disclaimer:
I do not normally follow users around the forums just to read and reply to them, but the fact is, you are asking for the same thing in two separate threads, and you have just proven something yourself.
Once again, TiLu640, I have to tell you that I mean you no offense, but you have just proven yourself that a video tutorial might not be as effective as you think it might have been.
Perhaps you should return to the tutorial thread and try reading the step-by-step instructions again?
Also, in response to your latest post, the fastest way for you copy and paste the scripts from the demo to your game, is to copy the entire Luna Base Engine project folder.
It would be best for you to start from the Luna Base Engine itself as your new project file, and slowly copy other scripts into it one-by-one to avoid script conflict, rather than the other way around.
