3.如何正确放置贸易站(英文)
5. How do I place a Trading Post (in the editor)? If I place a Socket, I cannot place the Post on top.
There're different kinds of Sockets (you can access a whole list of them in the Place Object menu). In order to make them work you have to distinguish between the two basic types:
A Socket as a Native American village:
Firstly, go to the Native American Manager. Tick the boxes to determine which tribes can be used on your map. Then place a Socket of that tribe and you can put a Trading Post on top.
A Socket next to a trade route is even easier:
Position the specific Socket for trade routes next to a trade route (use the Trade Route Tool to create one) and you can place a Trading Post on top. If there's no trade route next to it won't work.
