Thank you so much for your response. I followed your suggestions, and this is the result (which seems to work correctly):
If you have any suggestions to improve this code, please tell me. :)
I understand, that if I create an instance in an event, and then I want to assign a value to that instance with an action (within that event), Construct automatically selects that instance, and not all instances of the same object. Is this correct?
If in the same event I have to create more instances of the same object, how can I manage the situation if I want to assign a specific value to each specific instance? Is it possible to loop through all newly created instances within an event? Or do I have to create a specific function?
Sorry for the thousand questions, but I am very determined to learn how to use this program.
