How to verify if SetAnimation found an animation in UE4?

scardario

Hi, how can I use the track entry returned by the Set Animation node to verify if Spine found the animation on the skeleton? I tried to use "isValid" but it doesn't return invalid when the animation isn't found.

I could use the "get track end" function and check if it's 0, but I'm not sure if it works or if there's a better option.

Thank you.

The isValid() method is part of the UObject API, a UE4 thing, not Spine. You can query the skeleton for the animation via one of the findAnimation() methods. If that returns null, the animation does not exist. This has to happen before you try to queue an animation.

I didn't find the findAnimation methods. I looked for them in the anim and skeleton. Is this exposed to blueprints? Is a recent addition?

You can find it here: SkeletonData findAnimation. You can get the skeleton data from Skeleton data.

I retrieved the Skeleton data from the Skeleton Animation Component and it doesn't seem to have those methods:

Am I missing something?

I'm using UE 4.20.3

Ahh, sorry, since you said mentioned isValid() I assumed you were using the API from C++, not blue prints. There's currently no way to tell if the animation was found. I've created an issue for this here: [ue4] Add blueprint methods to query for available animations · #1289

I'm planning on doing an update of the UE4 runtime this week, so I should be able to get this in as well.
