TimeWarp.fixedDeltaTime vs Time.fixedDeltaTime

[AaronLS]

Is there a reason one would use TimeWarp.fixedDeltaTime in their fixedUpdate for physics?

I would hope if someone were doing a physics warp, then Time.fixedDeltaTime would reflect the appropriate delta so that it can be used regardless of warp.

My understanding is that Time.fixedDeltaTime is the basic deltaTime that comes as part of the Unity Engine defaults.

Then Squad, when they added Time Warp for KSP, added the TimeWarp class, so the difference is that Time.fixedDeltaTime is "realtime" since last fixedUpdate and ignores TimeWarp, while TimeWarp.fixedDeltaTime is the time since last frame, including compensation for Time Warp.

Fair warning that I have not actually used either, so please test if you are going to use either value.

Timewarp.(fixed)deltatime is AFAIK the KSP implementation of Time.(fixed)deltatime. You don't have to be in timewarp for the timewarp class to return correct values (but I can't comment on the reverse). I use the Timewarp versions exclusively reasoning that the KSP specific version is more likely to be correct in any given situation

[AaronLS]

That sounds like a good best practice.

I did some test and it appears with physics warp, both values are identical, I.e. 1x .02, 4x .08

With regualr warp though, x5 has Time.fixedDelta .02, and TimeWarp.fixedDelta .10

So you are right about using TimeWarp.
