How to add more gravity to the object?

Hi All, I know how to increase the gravity in editor , its in Edit>Project Settings>Physics.
By code also i know
Physics.gravity = new Vector3 (0,-15,0);

But How I give more gravity to the specific object that i want?

The Above two are effected all the object.
Thanks

 

If you have a rigidbody on it, just edit the gravity from the rigidbody.

 

@Ansity Can you really edit gravity for rigidbody? I didnt know that.. well if it doesnt work, you can always addForce(0,-15,0)

 

If you want "realistic" force, remember that gravity is not affected by mass, so you should use Forcemode.Acceleration. Putting one cube with gravity on next to a cube with gravity off and this code on it:

Code (CSharp):

1. public void FixedUpdate() {
2.     GetComponent<Rigidbody>().AddForce(Physics.gravity, ForceMode.Acceleration);
3. }

makes them fall exactly in lockstep, meaning that it's a good way to do gravity manually. So if you want something to fall twice as fast as "normal" things, you just do AddForce(Physics.gravity * 2f, ForceMode.Acceleration);

 

"If you have a rigidbody on it, just edit the gravity from the rigidbody."

U cant edit the gravity in rigidbody..

Baste
"AddForce(Physics.gravity * 2f, ForceMode.Acceleration);"

Its not taking exact gravity ,its pulling down force.
U check By editing the gravity in editor and writing this code , both are not same.
Is their any other way??

 

not being too funny but gravity is just a downward force...

they brought in http://docs.unity3d.com/ScriptReference/Rigidbody2D-gravityScale.html recently when the 2D engine got the effectors and things... don't think there is anything like that for 3D though.

 

Yes you can.

 

Oh, that is rigidbody 2d. Newer used those. It use different physics engine, perhaps there is some differences with settings.

edit: op was talking about 3d

 

ya am talking about 3d objects not for 2d. Thanks

 

oh I thought it was pretty much the same for 2D and 3D, fair enough.
