my second "if" statements doenst works help me

hi , im currently have a problem with my second if statement , im trying using if when changing the pict . but whenever after first if statement works , my second statement if will not working . im trying several solution and not working at all please help

here my code
thanks in advanced

Code (CSharp):

1.  timer -= Time.deltaTime;
2.                     if (timer <= 0)
3.                     {
4.                         if (uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "helmimg") as Sprite)
5.                         {
6.                             uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "handphoneimg2") as Sprite;
7.                             timer = delay;
8.                             return;
9.  
10.                         }
11.  
12.                         if (uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "handphoneimg2") as Sprite)
13.                         {
14.                             uploadimage.sprite = (Sprite)Resources.Load<Sprite>(filepath + "helmimg") as Sprite;
15.                             timer = delay;
16.                             return;
17.  
18.  
19.                         }

 

If you want the second if statement to work after the first one you need to remove the "return" statement. A return statement doesn't cause execution to leave the "if" statement. It causes it to leave the function.

 

hi sir , thankyou for responding ,
im removing return statement . but its makes even worse , even my first statement not working at all

Please post any errors you are getting.
You appear to have syntax errors in both of your if-statements:

Code (CSharp):

1. if (uploadimage.sprite = (Sprite) Resources.Load<Sprite> (filepath + "helmimg") as Sprite)
2.  
3. if (uploadimage.sprite = (Sprite) Resources.Load<Sprite> (filepath + "handphoneimg2") as Sprite)

You are using a single equals sign (which sets values) instead of a double equal sign (which compares values).

Also, just a fair warning that this code looks very inefficient. You should avoid loading resources and GetComponent calls every frame, as these are heavy processes. Instead, you should cache these values from the Start() or Awake() methods.
