i send you these photo so that you know whats the problem is
thankyou very much sir

im really stuck in here please help.

 

You assign local variable Timer = 3, then subtract Time.deltaTime from it.

That will be about 3.0f - 0.0166f roughly, so that will never be below 0, which is your next if statement.

Do you have a member variable called Timer that you are hiding with the local variable Timer?

 

im doing that script because i see someone youtube channel .
then what the solution sir ? thankyou for answering my question sir

 

even im trying changes time.deltatime to 1f its still not changed hmmmm

 

You need to initialize your timer and delay outside of your function.

Code (CSharp):

1. private float delay = 3f;
2. private float timer = delay;
3.  
4. void Update() {
5.     //Code before timer check here
6.     timer -= Time.deltaTime;
7.     if (timer <= 0)
8.     {
9.         //On timer...
10.         timer = delay;
11.     }
12.     //...
13. }

if you write "public" instead of "private" when initializing the delay you can modify your delay in the inspector.

 

im already trying somehow but i dont know why everytime i try the only work is before timer -= time.deltatime.
the only panel show the sprites is helmimg , its never change to handphoneimg2 and its not error T.T
hmm help me please

 

Code (CSharp):

1.  if (mTrackableBehaviour.TrackableName == "HELM")
2.         {
3.             playSound("sound/gabungan");
4.             uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "helmimg") as Sprite;
5.             timer -= Time.deltaTime;
6.             if (timer <= 0)
7.             {
8.                 if(uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "helmimg") as Sprite)
9.                 {
10.                     uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "handphoneimg2") as Sprite;
11.                     timer = delay;
12.                     return;
13.  
14.                 }
15.                 if (uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "handphoneimg2") as Sprite)
16.                 {
17.                     uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "helmimg") as Sprite;
18.                     timer = delay;
19.                     return;
20.  
21.                 }
22.  
23.  
24.             }
25.
