Question by SeabearStudios · Sep 14, 2016 at 12:50 AM · c#variable

Variables.

So I'm trying to make a power up that gives two times the speed for 10 seconds, but my variables or WaitRealTimeSeconds are wrong.(I don't know which one, but the log says the variable lines are causing the error) I try to call the variables but I get the error:

Assets/Scripts/PlayerController.cs(46,42): error CS0201: Only assignment, call, increment, decrement, and new object expressions can be used as a statement

Here is the script, also, it says the error for both variables.

     if (other.gameObject.CompareTag ("Speed")) {
         other.gameObject.SetActive (false);
         (float.speed * 2);
         yield return WaitForSecondsRealtime (10);
         (float.speed / 2);
     }

I also tried (speed * 2) but it didn't work so I looked at tutorials and they were in JavaScript and I need C#. Any help?

Lines 3 and 5 make no sense to me, what are you trying to do there?

This is assuming that you have a variable named speed somewhere.

  if (other.gameObject.CompareTag ("Speed")) {
      other.gameObject.SetActive (false);
      speed *= 2; // Can also be written as speed = speed * 2;
      yield return WaitForSecondsRealtime (10);
      speed /= 2; // Can also be written as speed = speed / 2;
  }

You should post the whole code or at least more of it next time, so people can see where the speed variable is declared, etc.
