Button Only Activates When Clicked Twice?! [HELP!]

I have a button under a canvas that when clicked should setactive 5 gameobjects... However, when I run the game, I have to click the button twice for the gameobjects to finally appear... I checked as you can see with Debug.Log("CLICK CLICK"), and when I click it the first time it does detect the click, but when it Setactive's the 5 gameobjects, they don't actually appear until you click the button again. Here is the script:

Code (csharp):

1.  
2. usingUnityEngine;
3. usingUnityEngine.UI;
4. usingSystem.Collections;
5.  
6. publicclassTitleButtons : MonoBehaviour {
7. GameObjectLoadingCanvas;
8. GameObjectMainCanvas;
9. GameObjectsphere;
10. GameObjectMoreGamesWindow;
11. GameObjectEightXEightButton;
12. GameObjectEightXEightText;
13. GameObjectBackButtonGames;
14. GameObjectComingSoonText;
15. GameObjectWebsiteURLText;
16.  
17.  
18.  
19. voidAwake () {
20. MoreGamesWindow = GameObject.Find ("MoreGamesWindow");
21. EightXEightButton = GameObject.Find("8x8Button");
22. EightXEightText = GameObject.Find("8x8Text");
23. BackButtonGames = GameObject.Find("BackButtonGames");
24. ComingSoonText = GameObject.Find("ComingSoonText");
25. WebsiteURLText = GameObject.Find("WebsiteURLText");
26.  
27. LoadingCanvas = GameObject.Find ("LoadingCanvas");
28. MainCanvas = GameObject.Find ("Canvas");
29. sphere = GameObject.Find ("Sphere");
30. }
31.  
32. //Usethisforinitialization
33. voidStart () {
34. MoreGamesWindow.SetActive (false);
35. EightXEightButton.SetActive(false);
36. EightXEightText.SetActive(false);
37. BackButtonGames.SetActive(false);
38. ComingSoonText.SetActive(false);
39. WebsiteURLText.SetActive(false);
40.  
41. LoadingCanvas.SetActive (false);
42. }
43.  
44. //Updateiscalledonceperframe
45. voidUpdate () {
46.  
47. }
48.  
49. publicvoidClicked () {
50. if (gameObject.name == "PlayButton") {
51. LoadingCanvas.SetActive(true);
52. MainCanvas.SetActive(false);
53. sphere.SetActive(false);
54. Application.LoadLevel("Game");
55. }
56. if (gameObject.name == "MoreGamesButton") {
57. MoreGamesWindow.SetActive(true);
58. EightXEightButton.SetActive(true);
59. EightXEightText.SetActive(true);
60. BackButtonGames.SetActive(true);
61. ComingSoonText.SetActive(true);
62. WebsiteURLText.SetActive(true);
63. Debug.Log("CLICK CLICK");
64. }
65. if (gameObject.name == "ShareButton") {
66. Application.CaptureScreenshot("Screenshot_Swervy.png");
67. }
68. if (gameObject.name == "TwitterButton") {
69. Application.OpenURL("https://twitter.com/PurifiGames");
70. }
71. if (gameObject.name == "FacebookButton") {
72. Application.OpenURL("https://www.facebook.com/Purifi-950120728411407/timeline/");
73. }
74. if (gameObject.name == "InstagramButton") {
75. Application.OpenURL("https://instagram.com/purifigames/?hl=en");
76. }
77. if (gameObject.name == "8x8Button") {
78. Application.OpenURL("https://itunes.apple.com/us/app/8x8/id1049171469?ls=1&mt=8");
79. }
80. }
81. }
82.  

 

Your code is too long. I advice you to put only necessary block of code.

 

I don't think that the problem is here, you have to look if there are is someone else who is making your object inactive. I suggest to Debug.Log the activeness of one of the objects and see if there is something strange.

 

or do you have a UI component "over the top" which is blocking the button and reacting to the first click itself?

 

Well, my "MoreGamesButton"'s parent is a Canvas. There are other buttons that are also "siblings" of "MoreGamesButton", and they all work... More Games Button is the only one that doesn't for some very strange reason.

 

I just found if an UI object is set to inactive before running the game in unity editor, then you need to setActive twice to actually show it. Not sure why.

 

Make sure that any scripts attached to the UI object doesn't have a gameObject.SetActive(false) in its Start function. I ran into this issue before, and was beating my head on why I had to call it twice, then remembered that everytime an object changes states from inactive to active, the start function is called!

 

Thanks for your info, but mine is different. If the objects are set as active when click the Play button, all works fine including using code repeatedly changing the active state(only call once works)

 

Thank you! I didn't know - but I should have known - that the Start function is called whenever an object is made active. This was driving me mad.

 

This is an old thread, but that is not true! Start is only called once for the lifetime of the script. It's called the first time it's enabled, and that's it. If you disable and re-enable the script (or game object), it's never called again.

 

True. Perhaps he meant "OnEable()"

 

I ran into the issue myself that Sun-Pengfei reported, is this a known bug?
(UI objects disabled in the editor need to have SetActive called twice (even just in direct succession) to apply the passed state the first time)

 

Please do not reanimate old threads. Open a new thread for your questions. Most likely it's not a Unity bug. Please give us more information, code, how do you do what you do (in CODE tags!) and screenshots about your inspector (the subject game object selected of course).

 

Here's a repro project. After Play, click a button, a subobject will be visible (expected), but no label above (unexpected), click it again, see the label appear above.
Now restart playmode, tick the toggle at the top (checked=true) and click a button once, see the label appear above.
Two places disable the label in question at awake and even though that shouldn't matter it seems as though the deactivations did stack.

 

Thanks!

 

Button is not invoking OnClick event on first click when previously you clicked something in editor window (inspector for example)
