Having a way to add new meshes to a Melee entity (not attached to the melee, but to the character) would be convenient.
This would allow to have one melee in each hand, akimbo style, and more cool stuff!
About the API design I'm not sure what could be the best:
  1. Having a new method that you'd call on a Melee instance
  2. Making a Character being able to carry multiple Melee (sounds a bit messy regarding how Pickables are handled)
