Trying to understand how iTween.FadeTo works

The following code is NOT working:

Code (CSharp):

1. ExecuteMe(){
2. ChangeGameObjectTextMeshAlphaColor(0f);
3. iTween.FadeTo(gameObject, iTween.Hash ("alpha", 1f, "time", 2f,
4. "oncomplete", "ReturnToOriginalAlphaTransparencyTweenOnComplete", "oncompletetarget", gameObject));
5. }

However, the following code is working:

Code (CSharp):

1. ExecuteMe(){
2. ChangeGameObjectTextMeshAlphaColor(1f);
3. iTween.FadeFrom(gameObject, iTween.Hash ("alpha", 0f, "time", 0.2f,
4. "oncomplete", "ReturnToOriginalAlphaTransparencyTweenOnComplete", "oncompletetarget", gameObject));

Unfortunately when the above code is executed a second time (or third, forth...), it does not work anymore. I mean, the game object keep being transparent.

The text I'm fading from transparent to opaque is a Text Mesh. The rest of the functions are next:

Code (CSharp):

1. private void ReturnToOriginalAlphaTransparencyTweenOnComplete () {
2. //iTween.MoveTo(gameObject,iTween.Hash("position",startingPosition,"time",0.5f,"delay",3f));
3. iTween.FadeTo(gameObject, iTween.Hash ("alpha", 0f, "time", 2f, "delay", 1f));
4.  
5. }
6.  
7. ///<summary>
8. /// Changes the alpha color of the text mesh of this game object.
9. ///</summary>
10. ///<returns>The game object text mesh alpha color.</returns>
11. ///<paramname="alphaColor">0 would set the color to transparent. 1 without any transparency</param>
12. private void ChangeGameObjectTextMeshAlphaColor (float alphaColor){
13. Color scoreMultiplierColorInSceneView = GetComponent<TextMesh> ().color;
14. scoreMultiplierColorInSceneView.a = alphaColor;
15. GetComponent<TextMesh> ().color = scoreMultiplierColorInSceneView;
16. }

Why is happening that weird behaviour?

 

I believe the solution to the second issue could be related to the following function:

• Stop(GameObject target, bool includechildren) Stop and destroy all iTweens on a GameObject including its children.
