Thanks @Rostam24 Ü That doesn't throw any errors or warnings, but the list still remains unsorted. This is puzzling.

Can you post some code? Is there a reason why you are not just using an if statement to check the current value of car speed and increase it only if its less than 30? Something like this:

if(speed < 30.0f) {
         // keep increasing the speed
}

Could you do a debug.log on the name property of each item in audioClips? Maybe x.name is the wrong property to use for orderby...

 –

hi @Rostam24 Debug.Log(audioClips[0].name); and Debug.Log(audioClips[19].name); both print the names of the audio clips successfully onto console. It is unusual though, that after that, the following error is thrown on the first Debug.Log > ArgumentOutOfRangeException: Argument is out of range. Parameter name: index

Hmm given the trouble you are running into, perhaps it makes more sense to load the files via code as well? Put the files in a Resources folder, then load them into the array or list using Resources.LoadAll

for some reason that didn't work for me, but I'll keep in mind what worked for you so I know my mistake is probably elsewhere. Thanks for all your help @Rostam24 ! Ü

You can use Mathf.Clamp to clamp the speed :]

float clampedSpeed = Mathf.Clamp(yourSpeedValue, minSpeedLimit, maxSpeedLimit);

@boogie77: http://docs.unity3d.com/Manual/LoadingResourcesatRuntime.html Create a folder called 'Resources' and put it anywhere in the assets folder. Now place the files in the Resources folder you just created. Now you can access it via resources.load

You Can set the speed limit to 30 when the key press down

void Update()
 {
        if (Input.GetKeyDown (KeyCode.DownArrow)) {
            			speed = Mathf.Clamp( speed, 0f, 30f);
         }    
  }
