[unity] the new eventsystem

Is there a good way to use spine animations with Unitys new Event System?

If i just have an object with a spine animation it doesn't receive events. I can work around it by adding an Image component (with a transparent image attached). But I don't know which size i should have it in to have the same since as the animation.

Is there anyway to get the spine object to receive animation natively?
Is there any major drawback to adding a Image component? How do i know which size to use?

The new UI and event system in Unity is open source, but that doesn't help me much, way over my head

Solved it for now by making my animation a child of an object with just a Image component attached (that is transparent). Letting the parent receive all the events.

It's a bit unclear how exactly you want to use Spine "with Unity's new Event System".

Do you want it to generate/fire events like OnPointerEnter or OnDrag? (http://docs.unity3d.com/460/Documentati ... igger.html)
Or do you want to be able to play Spine Animations with event handlers?
Are you using SkeletonRederer as part of a game UI?

Sorry for being unclear, I'm still new to this. I'm trying to recive events like:

void OnBeginDrag(PointerEventData eventData)

So I just attach the EventTrigger to my spine object then?

Thanks you! I'll try this tomorrow.

I don't know if that will work.
4.6 is brand new and I'm not too familiar with how the new UI components work yet.

I think the Image component way is fine as long as there's not too many of them.

From the looks of the script, it doesn't seem like it's optimized to not draw fully transparent images, though this is the recommended way of setting it up in the new UI, according to official Unity tutorials (which don't always give the best advice for some reason).

But even if you can't see it, it's still telling the GPU to draw a transparent box. And if you have lots and lots of these things, it can add up to slow down your game.
