public float gravityScale;

Description

The degree to which this object is affected by gravity.

In 2D physics, the gravity is a global setting in the Physics2D class but you can also control the proportion of that gravity applied to each object individually using gravityScale. For example, it may be easier to implement a flying character by turning off its gravity rather than simulating the forces that keep it aloft.

As the title says when player jumps the gravity scale of the rigidbody2d changes. I want to set it back to its default value after player lands to the ground. How to do it? Here is my code without all the solutions I tried, so you can see everything that does work.

private Rigidbody2D rb; private BoxCollider2D boxCollider2d; public float JumpSpeed; // Player's jump speed public float downScaler; // gravity to change [SerializeField] private LayerMask platformLayerMask; void Start() { rb = gameObject.GetComponent<Rigidbody2D>(); boxCollider2d = gameObject.GetComponent<BoxCollider2D>(); } private void FixedUpdate() { Jump(); } private void Jump() { if (IsGround() && Input.GetKey(KeyCode.Space)) { rb.gravityScale = downScaler; rb.AddForce(new Vector2(0, jumpSpeed), ForceMode2D.Impulse); } } private bool IsGround() { RaycastHit2D rayCastHit2D = Physics2D.BoxCast(boxCollider2d.bounds.center, boxCollider2d.bounds.size, 0f, Vector2.down, .18f, platformLayerMask); Debug.Log(rayCastHit2D.collider); return rayCastHit2D.collider != null; }

Once you touch the ground you set the gravity scale back to 1, that is the default value.

I am trying to change the gravity scale of my player object only in 3D mode, but there is no gravity scale in 3D rigidbodies.

How can you manipulate the gravity scale (or whatever it is called) for 3D rigidbodies? of the player?

I'm fairly new to unity and C# and I'm trying to understand how to change the gravity scale of my character when I press the space bar. When I debug it, it says that Rigidbody2D.gravityScale cannot be used as a method. Can someone explain why it brings this error and how to fix it?

public class PlayerMovement : MonoBehaviour { public float moveSpeed; private Rigidbody2D rb2d; public float addGrav; // Use this for initialization void Start () { rb2d = GetComponent<Rigidbody2D> (); } // Update is called once per frame void Update () { //Understanding::: If key pressed down, //Transform - method that manipulates position of object //Translate moves transform in direction/distance of translation. //transform.Translate(translation); if (Input.GetKey (KeyCode.UpArrow)) { transform.Translate (Vector2.up * moveSpeed * Time.deltaTime); } if (Input.GetKey (KeyCode.DownArrow)) { transform.Translate (Vector2.down * moveSpeed * Time.deltaTime); } if (Input.GetKey (KeyCode.LeftArrow)) { transform.Translate (Vector2.left * moveSpeed * Time.deltaTime); } if (Input.GetKey (KeyCode.RightArrow)) { transform.Translate (Vector2.right * moveSpeed * Time.deltaTime); } if(Input.GetKey (KeyCode.Space)) { rb2d.gravityScale (addGrav); } } }

rb2d.gravityScale is not a method, it's a field that you can assign value to.

use this

rb2d.gravityScale = addGrav; //to asign //other example rb2d.gravityScale += addGrav; //to add rb2d.gravityScale -= addGrav; //to substract

It's because the compiler were reading it as a method since you used parentheses instead of equal sign. it should be like so.

rb2d.gravityScale = addGrav;
