How to make slippery/smooth movement in Unity 2D?
Hi, I would like to make a slippery 2D movement for my game i'm trying to make. I've got the movement for my player character, how do I make it slippery?
Here is my movement code.
private const float MOVE_SPEED = 15f;
private Rigidbody2D rigidbody2d;
private Vector3 moveDir;
private void Awake()
{
rigidbody2d = GetComponent<Rigidbody2D>();
}
private void Update()
{
// Basic Movement for the player
float moveX = 0f;
float moveY = 0f;
if (Input.GetKey(KeyCode.W))
{
moveY = +1f;
}
if (Input.GetKey(KeyCode.S))
{
moveY = -1f;
}
if (Input.GetKey(KeyCode.A))
{
moveX = -1f;
}
if (Input.GetKey(KeyCode.D))
{
moveX = +1f;
}
moveDir = new Vector3(moveX, moveY).normalized;
}
private void FixedUpdate()
{
rigidbody2d.velocity = moveDir * MOVE_SPEED;
}
}
Hi! Try to use SmoothDamp (https://docs.unity3d.com/ScriptReference/Vector3.SmoothDamp.html) with the smoothTime at a high value.
For example:
float smoothTime = .1f;
float velocitySmoothing;
private void FixedUpdate()
{
targetVelocity = moveDir * MOVE_SPEED;
rigidbody2d.velocity = Time.deltaTime * Mathf.SmoothDamp(velocity, targetVelocity, ref velocitySmoothing, smoothTime);
}
Hi agian, this script works thank you so much @guubebra!
But how do you get that targetVelocity?
Cheers!
just define it somewhere, it's only used in fixed update
you can make it really slippery by just adding force to the rigidbody
// For moving right, simplified version though, add whatever you please
rigidbody2d.AddForce(Vector2.right);
