Why do i Instantiate twice?

I am developing a card game were i flip the card when the players have the same. During this process I should instantiate a new object but for some reason it is instantiated twice? ...and i am not able to understand why this is happening two times.

The code is for testing so it is not complete:

Code (csharp):

1.  
2. voidOn2TimeTap(TapGesturegesture) {
3. print ("===On2TimeTap=== xyz:" + xyz);>>> here I get "Instantiate xyz: 0"
4. xyz++;
5. //Flipobject - - - Makesurethattheclickisonappropriateobject
6. if (gesture.Selection.tag != "MultipleIcon") {
7.  
8. FlipCardAndUpdatedMasterList(gesture.Selection);
9.  

And here is the actual code with the instantiate:

Code (csharp):

1.  
2. //Flipcardanddoproperupdatesaswellasdestroyselectedprefab
3. voidFlipCardAndUpdatedMasterList (GameObjectcardToFlip_GO) {
4. print (" ===FlipCardAndUpdatedMasterList===");
5. //Clonethepositionofthe "old" object
6. Vector3pos_v3 = cardToFlip_GO.transform.position;
7.  
8.  
9. //Checkifitisthebackorfrontofobject
10. if (cardToFlip_GO.tag.LastIndexOf ("B") != -1) {
11.  
12.  
13. } else { //faceisup
14. //Loadabacksideprefabandsetcorrectposition
15. newClone_GO = Resources.Load("BackSide") asGameObject;
16.  
17. //Findcorrecttagname
18. convertedCardTag = CardsAndConversions.front2Back[cardToFlip_GO.tag];
19. //Setnewnameandtag
20. newClone_GO.name = convertedCardTag;
21. newClone_GO.tag = convertedCardTag;
22. }
23.  
24. //Removeflippedcardobjectfrommasterlist
25. master_GameObject_List.Remove (cardToFlip_GO);
26. //Addnewflippedcardobject
27. master_GameObject_List.Add (newClone_GO);
28. //Putnewobjectonthecorrectposition
29. newClone_GO.transform.position = pos_v3;
30. //Destroytheselectedobject
31. Destroy(GameObject.FindWithTag(cardToFlip_GO.tag));
32.  
33. //Instantiatethenewupdatedobject
34. Instantiate(newClone_GO);
35. print ("Instantiate xyz: " + xyz); >>> here I get "Instantiate xyz: 1"
36. xyz++;
37.  
38. }
39.  

I get 2 x "newClone_GO" instantiated but want only one.

Would really appreciate some help to understand why!

 

Well your code doesn't have any cycles and Instantiate is called only once. Probably your mistake is somewhere else, outside of this code. Maybe you have this script attached to 2 objects or something...

Does it print "===On2TimeTap=== xyz:" 4 times or what is the situation with log?

 

hmm something is very strange with this code as the above is executed multiple times, i just do not understand why.

 

I didn't read through your code. Just wanted to say if you use a Debug.Log() statement instead of print, the Unity Editor console shows a stacktrace of what is calling that function.

 

Thanks Garth.

I am using FingerGestures and I use "voidOn2TimeTap(TapGesturegesture) {" setup for two taps and I do trigger this function, which trigger the Instantiation, twice. Maybe it is something with that plugin that is the reason for this.

 

I was able to solve the problem by renaming:

Code (csharp):

1.  
2. void On2TimeTap (TapGesture gesture) {
3.  

to:

Code (csharp):

1.  
2. void DoubleTap (TapGesture gesture)
3.  

It may be a bug in Fatal Frog's FingerGesture implementation as I have "On1TimeTap" for single tap and had "On2TimeTap" for double tap. The names is pretty similar but when i changed the problem is solved.
