Demos and military parades

It's a bit complicated.
You will need some knowledge in programming to do that.
First, you need to place the demonstration\parade in your map. Change the object's name to something you will remember (like "demo01a", "demo01b", "demo01c", "demo01d"...).
To activate a demonstration, use the line:
demo01a, demo01b, etc. are the names of the demonstration objects.
MAIN.$strings.$newsticker_demonstration_text is a reference to the string file, it will add a news ticker announcing the demonstration.

To end the demonstration use the line:
Again, the function takes the same input.

We used those in Walden campaign. Actually Gilad did. You can check the code: http://www.cimexchange.com/files/file/565-walden-campaign/

If you use demonstrations without the timeline they appear randomly or never appear.
