[Solved] Godot 4 Inconsistent Slope Movement

I’m having trouble with the movement speed of my 2d platformer controller. The movement speed slows/gains speed on slopes. Here is a video showing the problem.

I haven’t really changed the default code that much, except using custom keys, adding gravity scale, and moving the input handling at process

Here is the code:

  public const float Speed = 300.0f;
public const float JumpVelocity = -600.0f;

public float defaultGravity = ProjectSettings.GetSetting("physics/2d/default_gravity").AsSingle();
private float gravityScales = 1;

public float Gravity => gravityScales * defaultGravity;

private Vector2 prevPosition;

public override void _Process(double delta)
    var velocity = Velocity;

    var direction = Input.GetVector("move_left", "move_right", "ui_up", "ui_down");
    if (direction != Vector2.Zero)
        velocity.X = direction.X * Speed;
        velocity.X = Mathf.MoveToward(Velocity.X, 0, Speed);
    if (Input.IsActionJustPressed("ui_accept") && IsOnFloor())
        velocity.Y = JumpVelocity;
    Velocity = velocity;

public override void _PhysicsProcess(double delta)
    var velocity = Velocity;
    if (!IsOnFloor())
        velocity.Y += Gravity * (float)delta;
    FloorSnapLength = 32;
    Velocity = velocity;

Fixed it by setting FloorConstantSpeed to true
