why unity official course use Time.deltaTime inside FixedUpdate
Here in this 2d platformer course he uses
void FixedUpdate() { velocity += gravityModifier * Physics2D.gravity * Time.deltaTime; }
why he uses Time.deltaTime inside FixedUpdate ?
as I read in other questions people answered no need to use Time.deltaTime inside FixedUpdate because it already has a same duration in all devices.
I think it's an error
It's used likely because you don't know the exact value Time.deltaTime holds at programming-time. Yes, documentation assures that it has the same values in all devices, but no one tells you the exact value to use in substitution, for instance "0.010 seconds", so its value is hidden. If this value would be constant, as it is, and publicly known and shown, so it would have been stored in a static const variable, like "pi greek" in Mathf. So, I suggest to use the hidden and unpredictable variable to be flexible. I hope to be usefull.
