I also want to ask there is a [SerializeField] private float maxFallingSpeed in the code but in the past video I don’t see this code

There’s a few possibilities.

1) Your wallLayer on your PlayerController.cs and wall object’s Layer is not set.

Check the gameobject you are using as your wall in the scene, and check that it’s layer is set to the same layer you put for the wallLayer variable on your Player.

—

2) Your “Wall Check” object is not far enough from your player to reach the wall before the Player’s BoxCollider2D.

Check the position of your Player’s BoxCollider2D and the position of your “Wall Check” object. Ensure that the object is outside the BoxCollider of your Player.

—

3) Your wall jump works but your sliding isn’t affecting the your fall speed against a wall

Your wallSlidingSpeed is, despite being set when created, not at a high enough value to have a significant change in speed.

Someone else had also experienced a seperate bug with the working walljump, i’ve provided an improved code in it too if you want to improve the code as well.
