RigidBody2D movement script

paste the code in update function
you need to add 2 variables
RigidBody2D call it rb
and
Float call it speed


here you can copy this code


if (Input.GetKey(KeyCode.W))
{
rb.velocity = Vector3.up * speedmove;
}
if (Input.GetKey(KeyCode.A))
{
rb.velocity = Vector3.left * speedmove;
}
if (Input.GetKey(KeyCode.S))
{
rb.velocity = Vector3.down * speedmove;
}
if (Input.GetKey(KeyCode.D))
{
rb.velocity = Vector3.right * speedmove;
}




if (Input.GetKeyUp(KeyCode.W))
{
rb.velocity = Vector3.up * 0;
}
if (Input.GetKeyUp(KeyCode.A))
{
rb.velocity = Vector3.left * 0;
}
if (Input.GetKeyUp(KeyCode.S))
{
rb.velocity = Vector3.down * 0;
}
if (Input.GetKeyUp(KeyCode.D))
{
rb.velocity = Vector3.right * 0;
}
