How to create multiple timescales to different rigidbodies?

Example Scenario:
I have 3 spheres falling down via gravity. They have same rigidbody data.
I want to make a script that would control the "timeScale" of these rigidbodies. How do I do that?

Big picture: I want to create a system that could control the time of different groups of objects.
Example: Group A has 1f timeScale, Group B has 0.5f timeScale, Group C has 0f timeScale (paused).

 

you cant, that just sounds wrong in more then one ways, timescale is in respect to your scene not individual gameobjects.

 

That's why I'm asking this. I don't need to use Time.timeScale per se.

Say, if I create my own variable "timeScale", how do I make my rigidbody be affected by my timeScale?

 

You an add a force multiplied by your time scale every FixedUpdate, simulating your own gravity.

 

multiple that to deltaTime.

relativeDeltaTime=timeScale*Time.deltaTime

 

Just question regarding this, and this might help him in the long run....
How would you "slow down time" for a certain object while and after it has been on a ramp and is now airborne?
Would it just be counteracting the gravitational force and the vector 3 forward of the object respectively?

 

I don't understand. Wouldn't it be just the same as how you handle it with x1 timeScale? What you're actually doing is supplying it with deltaTimes, but you're not gonna be changing how physics is done.

 

Basically the function for time.Timescale is this:

Code (csharp):

1. public float Timescale (float timefloat) {
2.    game.everythingRunsAt = timefloat;
3.    return timefloat;
4. }

So essentially you cannot use timescale to change each one individually.

No what they meant is that you change how physics moves your object. so e.g.
rigidbody.AddForce (Vector3.up * 10);

Try this to get you on the right track: http://unity3d.com/learn/tutorials/modules/beginner/physics/addforce

 

@djfunkey that reply was actually for you. I'm aware of what Time.timeScale and AddForce do.

Maybe my question was unclear. Let me revise it: "How can I create a system that could group object and control their time?"

 

You can't.

They're telling you that you need to multiply all of the physics inputs by that object's time differential. Per object.

 

Why are you telling me "You can't" when you're giving a solution? I'm pretty sure it's possible to do this system. Someone else has done it: https://www.assetstore.unity3d.com/en/#!/content/9603

 

Because you can't "control time" on individual objects.

Instead, what you can do is use a scale for each one and have each object apply that scale when it's doing time-sensitive things. Instead of "movement * Time.deltaTime" it's "movement * Time.deltaTime * scale".

Doing this to a "group" of objects would mean either setting each one individually or implementing some system where the object knows which scale to pull the value for and use.

You don't actually slow down time. You just slow down an object's movements.

This is especially important because physics is not affected.

 

Code (CSharp):

1. RigidBody2D rb;
2.  
3. private void FixedUpdate ()
4. {
5.     rb.gravityScale = timeScale;
6.     rb.position = (rb.position - rb.velocity * Time.fixedDeltaTime) + rb.velocity * timeScale * Time.fixedDeltaTime;
7.     rb.rotation = (rb.rotation - rb.angularVelocity * Time.fixedDeltaTime) + rb.angularVelocity * timeScale * Time.fixedDeltaTime;
8. }
