Set Position to...

So, I have this large, spinning wheel. (Imagine a Ferris wheel.)
I set the Hot spot in the center, to make it turn around a single point.
Then, I created 7 actives to rotate (At the same time) around the wheel, each on their own point.
At this point, nothing happened.
I tried to create it so that the actives would be set on the Action Point instead, and ended up confusing myself more.
I then tried to fix it by using the ellipse motion tool, which failed as well.

How can I make it so that the actives will move on time with the rotating wheel?

Action Points Example

Genre: Example
Extensions Needed: None
Description:
Did you ever need multiple action points? Such an unusaul example, and one of a kind, I just had to include this.
Instructions:
Run the mfa.

Give each an Angele_ and a Radius_
Use Sin and Cos to position the Actives relative to the Ferris Wheels Hot Spot

Nivram, the download doesn't work for me.

If you just have evenly spaced objects moving in a circle, it's probably easier to use maths.

eg.
+ Whenever...
-> Object: Spread value "0" in ID

+ Always
-> Object: Set X position to X("Wheel") + (Cos( Angle("Wheel") + ID("Object") * 360 / 7 ) * Wheel_Radius)
-> Object: Set Y position to Y("Wheel") - (Sin( Angle("Wheel") + ID("Object") * 360 / 7 ) * Wheel_Radius)

If you want to download the other example, you can find it here: http://www.sketchy.co.nf (the file called "Multiple Action Points"; also take a look at the file called "Orbiters").

Thank you! I think I can finally get it working now.

And I don't know why the example will not download from my site. Now we are both frustrated, because it works for me.

You can futureproof that equation by replacing the 7 at the end with Number of Objects ("Object"), so that if you decide to add or remove objects they will still orient themselves nicely around it :-)
