Add Gravity to Player

Physics Based Character Controller part 2

In this article we will add gravity to our player controller.

When player is NOT touching the ground we apply gravity. This is a float number we set at the top of our script. We can simply subtract gravity from the y value of our velocity.

void Update()
{
    Vector3 direction = new Vector3(Input.GetAxis(“Horizontal”), 0);
    Vector3 velocity = direction * _speed;
    if (_controller.isGrounded == true)
    {
         //do nothing
    }
    else
    {
         velocity.y -= _gravity;
    }
    _controller.Move(velocity * Time.deltaTime);
}
