Spine DropDownBoxes

BinaryCats

Hello,

Maybe this is more of a unity question, or maybe I should parse and change the names. But currently we have animations like Movement_Walk Movement_Run. In unity when a combo/Dropdown box is made, if names contain a / it will break it into a child. i.e. Movement/Walk would, in the dropdown box be Movement>Walk.

I know you do some magic to create these dropdown boxes. But is it possible to use a _ instead of a / as a break?

This is Mitch's code. I'm sure we can dig it up somewhere.

Yeah ive had a look, he just adds strings to a context box. but mitch magic is too strong

Mitch and his code:

I could just intercept the string it passes through, but then it would store the wrong value in the data. as it wouldn't 'decode it'

I can probably fix this. Which line/file is it?

SpineAttributeDrawers.cs

line 152:

[CustomPropertyDrawer(typeof(SpineAnimation))]
public class SpineAnimationDrawer : SpineTreeItemDrawerBase<SpineAnimation> {
   protected override void PopulateMenu (GenericMenu menu, SerializedProperty property, SpineAnimation targetAttribute, SkeletonData data) {
      var animations = skeletonDataAsset.GetAnimationStateData().SkeletonData.Animations;

  // <None> item
  menu.AddItem(new GUIContent(NoneLabel), string.IsNullOrEmpty(property.stringValue), HandleSelect, new SpineDrawerValuePair("", property));

  for (int i = 0; i < animations.Count; i++) {
     string name = animations.Items[i].Name;
     if (name.StartsWith(targetAttribute.startsWith, StringComparison.Ordinal))
        menu.AddItem(new GUIContent(name), name == property.stringValue, HandleSelect, new SpineDrawerValuePair(name, property));
  }
   }

}

Looks like it wasn't Mitch stuff after all:
https://docs.unity3d.com/ScriptReference/GenericMenu.html

Note the sample code:

menu.AddItem(new GUIContent("SubMenu/MenuItem3"), false, Callback, "item 3");

... is automatically parsed as a submenu.

What you could do is replace whatever character you want into "/" and use that modified string in new GUIContent.
Like in the code you cited above, you can change it to:

menu.AddItem(new GUIContent(name.Replace('_', '/'), name == property.stringValue, HandleSelect, new SpineDrawerValuePair(name, property));

Binary Cats, do you still need my help here? If so, I can tackle this. If not, might be faster for you to do it yourself.

its pretty magicall adding strings to dropdowns to me 🙂

But would that not Save the string Movement_Walk as Movement\Walk. And thus would not be able to used to play animations? (as the name is incorrect)

huh, I guess not. Thanks, this works. Maybe it would be nice to allow you to replace the separator?

Something like:

public class SpineAnimation : SpineAttributeBase {
     /// <summary>
     /// Smart popup menu for Spine Animations
     /// </summary>
     /// <param name="startsWith">Filters popup results to elements that begin with supplied string.</param>
     /// <param name="dataField">If specified, a locally scoped field with the name supplied by in dataField will be used to fill the popup results.
     /// Valid types are SkeletonDataAsset and SkeletonRenderer (and derivatives)
     /// If left empty and the script the attribute is applied to is derived from Component, GetComponent<SkeletonRenderer>() will be called as a fallback.
     /// </param>
     /// 
     public char m_Separator = '/';
     public SpineAnimation(string startsWith = "", string dataField = "") {
      this.startsWith = startsWith;
      this.dataField = dataField;
   }
     public SpineAnimation(string startsWith = "", string dataField = "", char Separator = '/')
     {
      this.startsWith = startsWith;
      this.dataField = dataField;
         m_Separator = Separator;
     }

 }

     }
