error CS0161: not all code paths return a value

Question

Idk what I did wrong. I've got code with "sNumber". If sNumber is equal to 1 something happens, if 2/3/4/5/6 something different. If my sNumber option is finished it change snumber to 0 what starts xWP. Check this code:

     IEnumerator xWP()
     {
         int i;
         i = Random.Range (1, 6);
         sNumber = i;
     }

There's something wrong. Whats wrong?

IEnumerator is the return type for a coroutine. Because of the nature of their implementation coroutines must be implemented over multiple frames. You can fake this like so.

 IEnumerator xWP(){
     int i;
     i = Random.Range (1, 6);
     sNumber = i;
     yield return null;
 }

Alternatively if you did not intend to write a coroutine then change the return type to void

 void xWP() {
     int i;
     i = Random.Range (1, 6);
     sNumber = i;
 }

try this

   IEnumerator xWP()
     {
         int i;
         i = Random.Range (1, 6);
         sNumber = i;
         yield return null;
     }

if you specify a type in the function declaration, unity(or any other complier) will require a return value of that type (or null)

so

 int onePlusOne()
 {
 int answer;
 answer = 1+1;
 }
 
 would generate your error, but
 
 int onePlusOne()
 {
 int answer;
 answer = 1+1;
 return answer;
 }
 
 would work correctly
