StairsSteppingBody3D

CharacterBody3D that automatically controlls movement up and down the stairs

How to use

• Set PLAYER_COLLIDER to whichever collider you want your body to use.
• Set velocity every physical frame to whatever value you wish to move;
• Don't forget to call super(delta) at the start of _physics_process if you are overriding it.
• Don't call move_and_slide() in your character controller, as the class calls it on it's own when calculating stair stepping.

Credits

Most of the code in this addon has been forked from other projects. Check out full list for more:

• Special thanks to Majikayo Games
  for original solution to stair_step_down!
• Special thanks to Myria666
  for paper on Quake movement mechanics
  (used for stair_step_up)!
• Special thanks to Andicraft
  for help with implementation of stair_step_up!
• Special thanks to JheKWall for
  original character controller demo
  this is based on!
• Vissa refactored previous code
  so that it could be used with Entity Component System or with Node Inheritance

Notes:

0. All shape colliders are supported. But Capsule colliders are recommended for enemies
   due to its compatibility with the Navigation Meshes. Its up to you what shape you want to use
   for players.

1. To adjust the step-up/down height, just change the MAX_STEP_UP/MAX_STEP_DOWN.

2. This uses Jolt Physics as the default Godot Physics has a few bugs:

   • Small gaps that you should be able to fit through both ways will block you in Godot Physics.
     You can see this demonstrated with the floating boxes in front of the big stairs.
   • Walking into some objects may push the player downward by a small amount which causes
     jittering and causes the floor to be detected as a step.

TLDR: This still works with default Godot Physics, although it feels a lot better in Jolt Physics.
