Character Step
This static class helps CharacterBody3D objects ascend and descend ledges such as stairs or obstacles. PhysicsServer3D.body_test_motion() is used to project the character as if they were moving up the ledge to test for collision. Then either a clear position is returned or the CharacterBody3D’s original position, where the body was before the projection, is returned to indicate the ledge can not be ascended or descended. This is a demo level that also includes a bare bones third person contro...
Character Step
These files are for a playable demo that include the main script that handles the step up/down functionality, as well as a basic third person controller and the demo level.
Go to Scripts/character_step.gd if you just want the file without the demo level and player controller.

Purpose:
This static class helps CharacterBody3D objects ascend and descend ledges such as stairs.
Usage:
Be sure to utilize these methods within the CharacterBody3D’s _physics_process() and to limit step_down and step_up calls when possible. For example they don't need to be called if not moving. step_down() does not need to be called unless the CharacterBody3D is falling. step_up() does not need to be called unless there is a wall/unwalkable surface in front of CharacterBody3D.
step_up should come BEFORE move_and_slide
It is designed to look ahead be used before applying movement to the character.
step_down should come AFTER move_and_slide
It is designed to fix character position after movement has been applied.

It did not quite work for me for my third person controller so I built my own, taking some techniques from it, but remaking it to work as a static class so it can easily be added to any character scripts.
