Posts from The StartAdvMapDialog script is not working.

Dear friends! I had some free time and decided to delve into the world of Mapmaking. Before, I dabbled in it occasionally, but without scripts or anything too complicated. But now that day has come.
I watched guides, read discussions, studied the standard manual, and gradually started creating a map line by line.
And then, when I already felt like a scripting guru, I encountered a problem that I tried to solve for about 5 hours, but couldn't figure it out. I am asking for help from those who know more!

The essence of the problem:
Here is my script:


Just so you know, I tried putting it in a separate function and not using `ifthen`, all to no avail. At the same time, the script for giving quests works!

Here’s what it looks like in the editor:


I also tried setting the camera settings manually and through the plus sign – nothing helps.

I don't quite understand what the problem is; is the video not playing?

And video number 0 was created (unlikely to be the cause, but just in case).

Yes, the video doesn't play. I've already tried deleting the first frame and making it the first, second – it doesn't help.
No errors are displayed in the console either.

I just created another completely blank map and... it worked...
But this time I created a single-player map, and before that, it was a multiplayer map. Could this be the problem?

Now everything is clear. In multiplayer, most of the scripts don't work (or rather, they have their own scripts).
