Creating a decision maker.

[ILogan001]

I want to create a movable gear or something like that for decision making. Here is how it should be like https://yesnopickerwheel.com/
Is it even possible?

Sure.
You can use physics constraint and give mesh a random impulse to rotate.

Or just rotate your mesh on the event tick for a random amount of time.
For a smooth slow down at the end, you can use interpolation.

When the mesh stops - based on its rotation, determine the answer. If the angle is from 0 to 60 - yes, if from 60 to 120 - no, etc. (remember that the rotation in unreal changes from -180 to 180).
