CharacterController Question

Hello, sorry if this is a stupid question, and sorry if it's in the wrong section of the forum.
I was taking a look at this link:
https://docs.unity3d.com/ScriptReference/CharacterController.Move.html
And in the example there is this:

Code (CSharp):

1. moveDirection.y -= gravity * Time.deltaTime;
2. controller.Move(moveDirection * Time.deltaTime);

Is this some kind of mistake? Why would the gravity need to be multiplied by Time.deltaTime, when the result is multiplied by it anyway? That would make the gravity be multiplied by Time.deltaTime^2, which seems incorrect to me.

Any clarification on this would be appreciated.
Cheers.

 

Interesting. Never used it. But I think, this may suppose to be like:

Code (CSharp):

1.  
2. moveDirection *= Time.deltaTime ;
3. moveDirection.y -= gravity * Time.deltaTime;
4. controller.Move ( moveDirection );
5.  

That would make more sense to me.

Which in fact is

Code (CSharp):

1.  
2. moveDirection.y -= gravity;
3. controller.Move ( moveDirection * Time.deltaTime );
4.  

 

Yeah, it's probably a typo.

Docs are often outdated. If in doubt - test it.

 

Looks right to me; gravity's an acceleration (m/s^2) and CharacterController::Move takes absolute movement delta, not a velocity.

 

Okay, good to see some people agree with me.

Hmm, interesting... That seems correct. I was wondering if that was the case.
Would you be able to explain the term 'absolute movement delta'? Sorry, it just doesn't really make sense to me

 

I think he means simply an acceleration. as delta of velocity, is acceleration. Similar delta of position is, is velocity. Where delta is a change, or difference.

While m/s^2 makes sens indeed and I was also thinking about it, it is badly presented in documentation.
