public static var gravity: Vector2;
public static Vector2 gravity;

Description

Acceleration due to gravity.

Set this vector to change all 2D gravity in your Scene. The default is (0, -9.8).

no example available in JavaScript
//Attach this script to a 2D GameObject (for example a Sprite).
//Attach a Rigidbody component to the GameObject (Click the Add Component button and go to Physics 2D>Rigidbody 2D)

//This script allows you to change the direction of gravity in your Scene by pressing the space key in Play Mode.

using UnityEngine;

public class Example : MonoBehaviour { enum GravityDirection { Down, Left, Up, Right }; GravityDirection m_GravityDirection;

void Start() { m_GravityDirection = GravityDirection.Down; }

void FixedUpdate() { switch (m_GravityDirection) { case GravityDirection.Down: //Change the gravity to be in a downward direction (default) Physics2D.gravity = new Vector2(0, -9.8f); //Press the space key to switch to the left direction if (Input.GetKeyDown(KeyCode.Space)) { m_GravityDirection = GravityDirection.Left; Debug.Log("Left"); } break;

case GravityDirection.Left: //Change the gravity to go to the left Physics2D.gravity = new Vector2(-9.8f, 0); //Press the space key to change the direction of gravity if (Input.GetKeyDown(KeyCode.Space)) { m_GravityDirection = GravityDirection.Up; Debug.Log("Up"); } break;

case GravityDirection.Up: //Change the gravity to be in a upward direction Physics2D.gravity = new Vector2(0, 9.8f); //Press the space key to change the direction if (Input.GetKeyDown(KeyCode.Space)) { m_GravityDirection = GravityDirection.Right; Debug.Log("Right"); } break;

case GravityDirection.Right: //Change the gravity to go in the right direction Physics2D.gravity = new Vector2(9.8f, 0); //Press the space key to change the direction if (Input.GetKeyDown(KeyCode.Space)) { m_GravityDirection = GravityDirection.Down; Debug.Log("Down"); }

break; } } }
