I want to make a new type of doors which are opening like in Joints 2 tutorial and I have 2 questions:

- is it good idea to base on Game::Item or better is to create new struct based on Game::Obj?

- how can I get actor direction/rotation to set properly joint direction? actor.matrix().x ?

1. Game::Obj
2. joint axis in door case should always be Vec(0,1,0)

How can I properly draw mesh with obj.scale and all rotations when I extend Game::Obj Class?
