Age of Empires 3 Set AI tutorial [High Quality]

You're welcome.

Take care.

but i have a question, how can you put the "scenario" i made, in the skirmish maps ??
( use my maps i made and use them to play online )

You can't use your map to play online. Because the map you have on your computer, other players won't. So, if you make friends playing online then you can have them use your map, that way you both are playing on a same map.

Once you set the "AI Standard" option, fights, construction, etc come automatically.

Watch the video from 0:45.

Do you see when I selected the AI start from the list? You simply scroll your mouse to select different units and once you click on their name, click on the map to paste them at that location.

You are asking for the scenario editor right? If you go in to object menu there will be a link that says "wall" click on it and you will see a small button appearing at the bottom of your screen. Using that you can build walls and gates when needed. Let me know if you can't find. What others thing you do not know?
