Hello,

Thanks a lot for getting Slate and for your feedback!
Considering I have understood correctly, I created a new action clip for easily attaching objects (props) to a child transform of the actor.
Bellow is the code of that new action clip which will also be included in the next version 🙂

I’ve also tested this along with an animation playing and it works as expected here.
Please let me know if that is what you were indeed after.
Thanks!

AttachObject.cs

using UnityEngine;

using System.Collections.Generic;

namespace Slate.ActionClips{

[Category("Transform")]

[Description("Attach an object to a child transform of the actor (or the actor itself) either permantentely or temporary if length is greater than zero.")]

public class AttachObject : ActorActionClip {

[SerializeField] [HideInInspector]

private float _length;

public Transform targetObject;

public string childTransformName;

public Vector3 localPosition;

public Vector3 localRotation;

public Vector3 localScale = Vector3.one;

private TransformSnapshot snapshot;

private bool temporary;

public override bool isValid{

get {return targetObject != null;}

}

public override float length{

get {return _length;}

set {_length = value;}

}

protected override void OnEnter(){ temporary = length > 0; Do(); }

protected override void OnReverseEnter(){ if (temporary){ Do(); } }

protected override void OnExit(){ if (temporary){ UnDo(); } }

protected override void OnReverse(){ UnDo(); }

void Do(){

snapshot = new TransformSnapshot(targetObject.gameObject);

var actorTransform = ResolveTransform(childTransformName);

if (actorTransform == null){

Debug.LogError(string.Format("Child Transform with name '{0}', can't be found on actor '{1}' hierarchy", childTransformName, actor.name), actor.gameObject);

return;

}

targetObject.SetParent(actorTransform);

targetObject.localPosition = localPosition;

targetObject.localEulerAngles = localRotation;

targetObject.localScale = localScale;

}

void UnDo(){

snapshot.Restore();

}

Transform ResolveTransform(string name){

if (string.IsNullOrEmpty(name)){

return actor.transform;

}

foreach (var t in actor.GetComponentsInChildren<Transform>()){

if (t.name == childTransformName){

return t;

}

return null;

}
