How to change slot or hide attachment？

pascalkk

As the picture：

I want hide this arrow in runtime，when the "bow shoot" animation half played。
And I tryed hide attachment like this:

 
this.roleAnima.GetComponent<SkeletonAnimation>().skeleton.FindSlot("arrow").Attachment = null;

And nothing happened.

Is there something I did wrong?
Or should I change the slot "arrow" to a slot "arrow_empty"? How to got this by code?

thanks for response~

That will work. Note if you are applying an animation that shows an attachment for the arrow slot, that applying the animation will set an attachment. In that case you can set the attachment to null every frame. This may seem odd, but you don't really want your game state being stored in your skeleton anyway!

Pharan

var skeletonAnimation = roleAnima.GetComponent<SkeletonAnimation>();
var slot = skeletonAnimation.Skeleton.FindSlot("arrow");
slot.Attachment = null;

That is equivalent code.
What this does is set the active attachment of your "arrow" slot to null.

If your animation keys the arrow attachment, that is also equivalent to the runtime saying slot.Attachment = arrow.
This is important to remember when you're doing stuff like this: your animations can override your changes.

So if you want something to be under the control of your code, you need to
a. not key it in your animations, or...
b. set the slot attachment every frame (and in the phase of the frame after the animations are applied). or...
c. play animations that key the attachments. (for example, a separate animation that only hides the arrow attachment in the arrow slot, played on track 1).

@Nate，@[cancellato] Thank you,This Attachment always showed cause I Key a Frame In Spine Editor。

I solved this By Nate's way, Use Spine Editor and not just try is in runtime。
Thanks again。
