Detect collision between StaticBody2D and CharacterBody2D

And, is_on_wall() is kind of inconsistent, sometimes it goes false for a frame after starting the slide.

This issue may be caused by the order in which you handle the simulation. Here is another post I wrote:

Help collision state when slope

You might get some chaos in the player CharacterBody2D, like func _physics_process(delta: float) -> void: # You wrote your code here, which is not cool move_and_slide() velocity.y += gravity # You wrote your code here, which is not cool too To make physics as smoothest as possible, the order of the move_and_slide() method and the velocity.y += gravity statement is func _physics_process(delta: float) -> void: # You wrote your code here, which is awesome velocity.y +=…

I noticed this issue while working on physics simulations with the state machine, where a slight change in the order impacted the simulation quality.
