Creating water current in a bay!?

[davaeron666]

I'm creating a map in the map editor and I want an area of it to be a bay. It will be connected to the ''off the map'' ocean but I do not want any river to flow into that bay. How can I make current in that bay for the sewer to flow to the ocean. I have tried making a water cyclinder thingy that creates water and another that sink water in on opposite sides of the bay but I get no current.

The ocean is a static body of water that is filled from the outside map boundaries. It will not have a current. A river flowing into it will produce a little current and may move towards the edge of the map if it is strong enough. The water spawners you're trying to use to create an artificial push/pull effect will not be able to compete with the volume of water in the ocean. Not only that, whatever the producing spawner creates, will simple drain off the edge of the map, while the drain spawner will simply draw more water in from the edge of the map, meaning that there won't be a current between the two spawners. Or at least not one that would be observable.
You have two options:
Instead of an ocean, make it a very broad river channel. Seal the map edge at the source point and place your spawner there. You may have to create a subtle sloping gradient of the sea floor from the source end to the exit point. Then gravity will assist you.
Or, seal all sides of the 'ocean' making it in effect a huge lake. Now that it is a closed body of water, your strategy of using a system of push/pull spawners is likely to work. That would also mean though that you would not be allowed to use that body of water for shipping lanes.
Hope that helps ;)

Just been experimenting and managed to get a water flow by doing exactly as you described !!
I put a water source one side and another the other side. Flow was set to 0.74, left side was at water height and right side was below water height (though not even massively below water height). The distance between the water sources was basically 1 tile. I got very strong current arrows.

Just seen grapplehoeker's reply. He may well be right about the ocean being too large a volume to affect. My experiments rather match what was described in the second paragraph of his post as can be seen from the screen shot below:

But I would expect to create a shipping lane as long as the water goes to the edge of the map.

Ok so because I wanted this bay to be a port, it had to have connection for boats. Thanks for your advices. I made a narrow but deep river with a slight slope toward the bay and I made a water spawner upstream. It separates the farming area and it will add some eye candy. I removed the other water spwaner that was was ''despawning water'' because like you said it was also bringing some of the ocean water in the bay. Now I have a minimal but present current that flow towards the border of the map. The poop will flow ! Thanks!
