Everything looks good!

There is only one Nullpointer Exception happening in All / 1 / Instrumented Unit Tests / org.catrobat.catroid.test.physics.look.PhysicsLookPositionAndAngleTest.testCloneValues (See Jenkins report) that is NOT RELATED to the implementation of this PR:

In PhysicsLookPositionAndAngleTest.testClonesValues, the Nullpointer Exception happens because the mocked PhysicsObject used in the test doesn't handle currently a call to its body field, which is null. I have attached below an image that shows where the null object reference happens. This could maybe be fixed in a separate ticket.
