Unreachable Code Detected (Why?)

Question

So, why is it that there is unreachable code detected in this code:

      public bool GetKeyPressed(KeyCode key)
    {
        for (int i = 0; i < keys.Count; i++)
            if (keys[i].key == key && keys[i].pressed)
                return true;
            else
                return false;

        return false;
    }

The index (i) is apparently unreachable ... why?

Answer 1

Your code has a loop that evaluates once, therefore the first iteration will always return.

If that's what you want, just say that,

return keys[0].key == key && keys[0].pressed;

If however (which is what I suspect here), you want to return true if any in the array meets your test, then use LINQ's Any(),

return keys.Any(k => k.key == key && k.pressed);
