C# runtime inquiries

I want to know how to do the following things in C# unity runtime by code.

Change animation draw order in run time.

Notify when a animation has complete.

Running animation backwards (if possible)

Thanks

In Start() cache the SkeletonAnimation component:
sk = GetComponent(SkeletonAnimation);

Then in code for playback speed and playback direction, use:
sk.timeScale = speed;

And for notification if it's complete use:
if (sk.state.IsComplete())

I haven't messed with draw order yet.

Oh cool. I didn't think using a negative number for the skeleton timeScale would reverse the animation. Is that supported (and stable)?

Nate

Passing a negative timeScale should be a fine way to reverse the animation.

You can change the draw order by changing "sk.skeleton.DrawOrder" which is a List<Slot>. Change the order of the list to change the draw order.

So if says I need to change the draw order for a specific action or frame, how do I get the current action or frame? I guess I need to change it back to original state after that frame/action as well.

Also, this list seemed to contain Slot object and has all sorts of complications, do I just simply swap the Slot object in the list? If yes do I use the standard

a = temp b = a b = temp

procedure?

Nate

Yes, you can swap the order of objects in the list.

You can use the time of the animation to change the order. Multiply the time by 30 to get the frame. You can get the time from AnimationState Time.

Okay... but why not just make animation frame a variable in the skeleton itself?

Nate

Because that would be storing the same information twice.

I tried the negative number a few days ago and it didn't work. But I didn't look into it too thoroughly.

Do you know how to set playback time for a single animation? I saw on the skeleton there is a playback time and I assume that's for all animations.

Nate

Skeleton has a time but it is unrelated to animations. It is used so slots can track how long an attachment has been set. This enables attachments to animate themselves based on the attachment time (eg, to show sprite animation).

Animation time is managed by AnimationState. Eg "animationState.time = 1.2". The time is in seconds.
