The ability to modify the instance variables of multiple instances of an object at once in the Editor

As written above

Having the ability to modify multiple instances’ variables in the editor would make it significantly easier to create formations of enemies with shared variables.

What you’re describing here is both what the For Each event type is for AND what the “pick all” conditions are for.

Either should accomplish your goal.

Do you mean in the editor rather than events? Eg Select 6 of the objects and change a variable.

You can’t do that in the editor, unfortunately. Hopefully that will be possible eventually.

I meant moreso in the editor. Currently, editing instances of an object in mass is not functional.

Can you edit the title and description to make it clear that’s what you mean. I think it would be useful to be able to do it!

I cannot. The title edit is locked.

I’ve gone ahead and updated the title.
