horizontal movement
how can i instantly change the the direction of a force and speed aplyd to a 2D object
I am making a 2d sidescroller and i want that if the character changes its direction the speed he is traveling at in 1 direction is also used in the other direction
h = Input.GetAxis("Horizontal");
if(Input.GetKey(KeyCode.LeftArrow))
{
if(h*rigidbody2D.velocity.x < maxSpeed)
{
rigidbody2D.AddForce(new Vector2(Time.deltaTime*speed*(h*rigidbody2D.velocity),0)); }
}
if(Input.GetKey(KeyCode.RightArrow))
{
if(h*rigidbody2D.velocity.x < maxSpeed)
{
rigidbody2D.AddForce(Vector2.right*Time.deltaTime*speed+(h*rigidbody2D.velocity));
}
}
any suggestions on how to do that? thanks in acvance

In stead of imidiatley applying the force to the object you could store the value of the force and apply in which direction you require.
eg
if(Horizontal != 0 && currentSpeed < max speed){
currentSpeed += 0.1 * time.deltatime;
}
rigidbody2D.velocity = new Vector2(currentSpeed * Horizontal,0);
being that Horizontal is from -1 to 1 any value for current force will be applied appropriatley.
i hope it helps
