Question Rigidbody.MovePosition

Hello, I have a question regarding Rigidbody.MovePosition:

Example from UnityDocumentation - Version 2022.3:
void FixedUpdate()
{
//Apply the movement vector to the current position, which is
//multiplied by deltaTime and speed for a smooth MovePosition
m_Rigidbody.MovePosition(transform.position + m_Input * Time.deltaTime * m_Speed);
}

Question: what would be more appropriate, Time.deltaTime, as in the example above, or Time.fixedDeltaTime, as in UnityDocumentation 2019.4?
Another question: would be correct, instead of "transform.position + m_Input", to use "m_Rigidbody.position + m_Input"?

Thank you for your attention, any comments are welcome.

 

Time.deltaTime is more appropriate. When used inside a FixedUpdate method, it returns Time.fixedDeltaTime.

About the second question, using Rigidbody.position is more correct than Transform.position. For example, if rigidbody interpolation is enabled, the physical position (Rigidbody.position) will differ from the visual position (Transform.position).

 

Hi @Edy and @MelvMay
It's more clear to me now.
Thanks for the help!

 

Thank you, I appreciate you.
