follow-up to latest merge.

[ArokhSlade]

• combined combat mechanics
• and player animation
• and did some necessary adjustments

  • replaced player model
  • adjusted hitboxes

• plus some small addons

  • player health display
  • made player health @export, so designers can tune it
  • locked player and monster z coordinate
  • disabled player "slide on ceiling"

    • doesn't seem to make the desired diffference, though

BUG:

• enemy.gd:88: if player and is_on_floor(): var direction = (player.global_transform.origin - global_transform.origin).normalized()
  • Invalid access to property or key 'global_transform' on a base object of type 'previously freed'.
  • (happens when player and monster die at the same time. i don't understand why, since player is checked against null but we'll keep an eye on it)
