Variable jump height not working in godot 4 c#

Question

I am very new to godot, and one of the first things I am trying to do is make a simple 2D platformer. I am using C#, as I am already familiar with Unity, and my script is acting kind of strange. My intention is to have a character that can be moved left and right, a jump with coyote time and a jump buffer, and variable jump height, but the variable jump height isnt working. Here is my script, which is attached to a CharacterBody2D, which is the parent of a sprite2D and CollisionShape2D:

using Godot;
using System;
public partial class Player : CharacterBody2D
{

	public bool CanWallJump;
	public float movementSpeed = 150f;
	public float jumpVelocity = 200f;
	public float CoyoteTime = 0.4f;
	public float CoyoteCount;
	public float Buffer = 0.2f;
	public float BufferCount;
	public float gravity = ProjectSettings.GetSetting("physics/2d/default_gravity").AsSingle();
	// Called when the node enters the scene tree for the first time.
	public override void _Ready()
	{
	}

	// Called every frame. 'delta' is the elapsed time since the previous frame.
	public override void _PhysicsProcess(double delta)
	{
		Vector2 velocity = Velocity;
		if(IsOnFloor() == false)
		{
			velocity.Y +=  gravity * (float)delta;
		}
		if(IsOnFloor())
		{
			CoyoteCount = CoyoteTime;
		}else{
			CoyoteCount -= (float)delta;
		}
		if(Input.IsActionJustPressed("Jump"))
		{
			BufferCount = Buffer;
		}else{
			BufferCount -= (float)delta;
		}

		velocity.X = 0;
		if(Input.IsActionPressed("Left"))
		{
			velocity.X = -movementSpeed;
		}else if(Input.IsActionPressed("Right"))
		{
			velocity.X = movementSpeed;
		}

		if(CoyoteCount > 0 && BufferCount > 0)
		{
			velocity.Y = -jumpVelocity;
		}
		
		if(Input.IsActionJustReleased("Jump") && !IsOnFloor())
		{
			velocity.Y = velocity.Y * 0.1f;
		}

		if(CanWallJump)
		{

		}

		Velocity = velocity;
		MoveAndSlide();
	}
}

Any help would be greatly appreciated. Thanks in advance!

I don’t know why your Jump should work here.
you use BufferCount = Buffer; on jump,

[shatteredreality]

Maybe 0.1 is too small to be noticed? What if you set velocity.y to 0 instead when releasing the jump button? (make sure to only do that if velocity.y is negative)

turns out it was something to do with the jump buffer, although I dont know what, because removing that fixed basically all my issues.

Thanks for all the help!
