We want to constrain the eyes to look the same way.
Add a bone between the control points with "Bone Tool".
You simply select "Add Bone" and drag a line from one control point to the other.
Select "bone1" under "Variables" at the right and change the bone type to "LESS".
Hit F7 and test. Now the eyes can't look in opposite direction because the control points can't be moved longer from each other than the bone distance.
One more thing: The control points are somes hard to find in a Stickman scene.
We are going to add some graphics that is only visible in control points tool that makes it easier to locate the control points.
Add one ellipseBorder for each eye as in the picture.
Change the "Pen" property to semi-transparent turqouise.
Set width to 10.
Use the "Put in Matrix" action on both borders.
Don't care about the names.
Then use "Attach" action on the new matrices.
Choose "Single Point" and select the respective control points.
Hit F7 and drag the control points.
The turqouise borders follow the control points.
The last thing to do is to put the matrices with ellipse borders in a design element. This will only show the borders when the control points tool is active.
You have now learned how to create eyes with Elemento.
