I made a sphere revolving around the center, in a timer. I multiplied a sphere with a center (3) All three spheres are attached to one center. Although they have other centers. I have already done using object groups. Nothing helps.
It’s impossible to make this moment more operational. You just want to propagate the objects and that they would carry out the same logic but with those objects that were copied. It will greatly simplify life.
I think each object should be assigned an ID number-automatically.
In the program code, when the condition is met, execute the object ID in turn for each new group - the same action. That is, to distinguish between objects for events.
