How do I paste entities from other projects?

I just got started making a project and I wanted to paste the FPS camera from the Physics demo into the starter project.
I couldn’t.
Help?

You can’t currently do this (although it’d be cool if you could!). Unfortunately, the route to achieve this is to manually recreate the entity.

Note that you can copy and paste entities in different scenes within the same project.

We’ll make this easier in future.
