I was wondering if there were a way to make it so multiple objects would act almost like one. I have created a character that is basically a lot of flat objects on top of each other to give a 2D impression but I don't want to have to move each individual item every single time the character moves. Would it be possible to just have them all move together? So if I moved one 2 units over, the rest would as well?
why not parent them CTRL+P (keep offset) under an "Empty" (to use it as a control object) which will be also nested under the main object that you want to inherit the movement from ?
Another method would be to use constraints (like copy location) but I wouldn't suggest you to do it for such simple task.
PS : You may also parent them directly to the main object that you want to inherit the movement of course.
