how to set the direction of world.playeffect smoke

i need to set the direction. i have world.playeffect(location, Effect.SMOKE, 0) and i have a couple others. i was wondering if the zero is degrees or something. help?

Something to do with intensity or time from what I gather. I think @r0306 knows because he had a thread a while back about effects

To set the direction, you need to define the data value as one of the parameters. It was:

world.playEffect (Location location, Effect effect, int data, int radius);

where data is one of the following:

ID Direction
0 South - East
1 South
2 South - West
3 East
4 (Up or middle)
5 West
6 North - East
7 North
8 North - West

How would you set it up like that? For example"
Player player = (Player) sender;
which makes the "player."

What would I have to right for the
"world.playEffect(location, Effect.MOBSPAWNER_FLAMES, 8);"

I use player.getWorld().playEffect(location, Effect.MOBSPAWNER_FLAMES, 8);
Am I doing it right?
