Shooter Example Project - need explanation

Thanks for releasing a good project but I find it confusing to understand.

  1. There is no character blueprint, only pawn blueprint.
  2. In the pawn blueprint, there is no camera. How it is being added and where, and why it is not in the pawn blueprint? Isn’t it more logical to have it inside pawn blueprint?
  3. In the player pawn bp the weapon comes out of nowhere: there is no static/skeletash mesh component for the weapon and it can’t be selected, however, it is there! Why to do like this? And how?
  4. Why name “pawn” is being used instead of “character”?
