Question by digitaldebonaire · Apr 13, 2014 at 02:06 AM · javascriptfor-loopsyntax

Can someone explain the js syntax of for(;;) to me?

I'm reading the Unity documentation on using coroutines and I found this

 function ProximityCheck() {
     for (int i = 0; i < enemies.Length; i++) {
         if (Vector3.Distance(transform.position, enemies[i].transform.position) < dangerDistance) {
                 return true;
         }
     }
 
     return false;
 }
 
 IEnumerator DoCheck() {
     for(;;) {
         ProximityCheck;
         yield return new WaitForSeconds(.1f);
     }
 }

After IEnumerator DoCheck() it says for(;;)

What does that mean? I tried googling "javascript" + "for(;;)" + "syntax" and all I get is tutorials on loops and javascript syntax.

So what does it mean to test for(;;) ?

for(;;)

is essentially an Infinite loop. The same as doing while(true), true will always be true so the loop will never end.

for(;;) is a for loop without an Initialiser, a Condition or an Increment.
