How to change the position for gravity?

Questions & Answers
1

I am creating a 3D game where the player can push a button, and “position” of gravity will be shifted. To make it any clearer, if I press T in the game, all objects and including the character will move upwards because gravity has been re-positioned so that the ceiling is now the new floor or the level. Same thing with the walls. This is what I have been using so far but it isn’t workng:

private void Start()
{
      ...
     Physics.gravity = new Vector3(0, -1.0f, 0);
}

private void InputManager()
{
     if (Input.GetKeyDown("T"))
     {
           Physics.gravity = new Vector3(0, 1.0f, 0);
     }
}

Is there another function I should be using or is the solution more complicated than this? The camera isn’t an issue by the way.

Try this sample code :

using UnityEngine;
using System.Collections;

public class ChangeGravity : MonoBehaviour {

	// Use this for initialization
	void Start () {
		Physics.gravity = new Vector3(0, -1, 0);
		GetComponent<Rigidbody> ().drag = .5f;
	}
	
	// Update is called once per frame
	void Update () {
	
		if(Input.GetKeyUp(KeyCode.UpArrow)) {
			Physics.gravity = Vector3.up * 5;
		}
		else if(Input.GetKeyUp(KeyCode.DownArrow)) {
			Physics.gravity = Vector3.down * 5;
		}


	}
