Setting the gravity of an object

Hi guys!

How can I set the gravity of an object in an event that gets called when you touch/click at the screen?

Thanks

 

Get the Rigidbody from the object, and set "useGravity" to true.

If you want to change object mass in runtime use Rigidbody.mass with the object you want interact:

The OP wants to change the gravity experienced by the object, not the mass. Changing the mass of an object would not affect the acceleration experienced by it.

I find it strange that there is no 3D equivalent of Physics2D.gravity (or maybe I just haven't worked with 3D enough!). I think the solution to the OP's problem is using Rigidbody.Addforce with Forcemode.Acceleration.

 

There are two ways to add gravity to an object. The method mentioned by @Jaimi is the way to apply gravity on a global scale. If you want a different gravity setting for one or more objects though, you can add a Constant Force at runtime and adjust accordingly.

Code (csharp):

1. public ConstantForce gravity;

Code (csharp):

1. gravity = gameObject.AddComponent<ConstantForce>();
2. gravity.force = new Vector3(0.0f, -9.81f, 0.0f);

Keep in mind if you use the local method without disabling the global method for your object (through useGravity), you'll have both effects at once.

Code (csharp):

1. gameObject.GetComponent<Rigidbody>().useGravity = false;

 

Just add an exponential down force ...

Code (CSharp):

1.    
2. public float GravityMultipler;
3. float AddGravity;

Code (CSharp):

1.     void Update()
2.     {
3.             AddGravity += GravityMultipler;
4.             _rigidbody.AddForce((Vector3.down * AddGravity), ForceMode.Acceleration);
5.  
6. ......

So you can maintain normal gravity to everything else.
