Confused about timing systems in Phaser

[Cola_Colin]

So I am building a game where I for some parts use tweens that interact with gameplay. Other parts of the gameplay are based on time.physicsElapsed.

I believe using time.physicsElapsedfor every frame (call to update) should cause the gameplay to slow down together with the fps, which is what I'd like to have as I have decided that is the most graceful way to deal with weak devices.

What I am confused about is how tweens are timed. 

http://phaser.io/docs/2.6.2/Phaser.TweenManager.html#frameBased makes it look like only frameBased Tweens are using the physics time and that isn't the default setting.

http://phaser.io/docs/2.6.2/Phaser.Time.html explains that Physics Time is used for tweens. Which seems to contradict the above finding.

So if I combine tweens with other timings that work on counting time.physicsElapsedin each update() call will that work consistently or not? I am worried that fps drops will slow down some parts of the gameplay, but not others. Do I need to switch the tween manager to use frameBased tweens if I want it to stay in sync with the rest of the physics time in low fps situations or not?

Tweens use Game Time unless set otherwise. You can use

game.tweens.frameBased = true;

Okay, thanks I'll do that then.

EDIT:

Turns out the documentation of http://phaser.io/docs/2.6.2/Phaser.Tween.html#to isn't fully correct. It states this about the duration:

" Duration of this tween in ms. Or if Tween.frameBased is true this represents the number of frames that should elapse. "

Even if Tween.frameBased is true the duration still has to be passed as a ms value, not as a number of frames. That's nice and makes handling this easier, the documentation appears to be misleading here. The only difference due to frameBased is here I think: https://github.com/photonstorm/phaser/blob/v2.6.2/src/tween/TweenData.js#L370 and that's the difference I want.

That's good since I was dreading converting all my tweens to frame-based.
