How do I resolve this problem?

how can I create a loop that allows you to spin endlessly by replacing 3 objects?

(example: 3 objects: Red, Yellow and Blue arranged in a kind of triangle. I want to make the Red go into the position of the Yellow of the Yellow in the Blue and the Blue in the Red. but if I use "set position to" the last, the Blue, goes to the place of the Red, but the Red is already in the place of the Yellow and so from three colors they become two because the Blue rests on the Red)

I'd recommend an invisible helper object(s) as a reference to keep track of locations. Either a single object with 3 image points or 3 separate instances. They are position 0,1, and 2. On trigger move the visible objects from position 0 to 1, 1 to 2, and 2 to 0.

Or pin the objects to the helper object, and rotate the entire helper object 120 degrees.

There are many options to approach this.
