How do I pin two copies of the same object together?

I'm making a drag and drop thing where if I place two blocks next to each other, they pin to each other and can be moved together when either one is picked up, but for some reason I can't figure out how to get it to work because it all wants to pin to a single block. Is there a way I can fix this or is there something I should use instead? I need them to be pinned by XYZ and angle.

You will need to use a family. Add the sprite to a family, move Pin behavior to the family level.

Then you will be able to pick one instance of the sprite and another instance of the family in the same event and pin them together. For example:

Sprite On Collision with Family : Sprite Pin to Family

I just tried the families trick, it didn't make a difference, they still all seem to be pinning to a singular instance of the object. Would I still be able to create hierarchies if they're not being created at or before runtime?

The family trick should definitely work. But either you are using Pin or hierarchy, one instance is always a "parent" and another a "child". You can only control the parent instance.

If you want to combine two instances and control them as a single object, you might need to think of some other approach. Maybe use an invisible sprite as a parent object, and pin both instances to it. Or paste them on a DrawingCanvas and destroy the original instances afterwards.

I'll have to try that, thank you!

Here is one possible idea:

I linked them by instance variable but you can use any other method as long as you can pick the whole group at once to create the container.
