Question by Wenon · Jun 15, 2018 at 09:29 AM · arrayindexout of range

Array index out of range after build

Hello, In editor works good but after build there is error IndexOutOfRangeException: Index was outside the bounds of the array.

                 int rand = Random.Range(0, (cars.Length));
                 vehicle = Instantiate(cars[rand]);

I tried with cars.length-1 too but not working. There is only one element in cars array but will be more but at this time I want to make it works with one element in the array. Why in editor it works but not after build?

Are you sure cars.Length is greater than 0 in the build? How do you populate the array? Can you:

  1. Add a Debug.LogError(cars.Length); before calling Random.Range

  2. Open your build settings

  3. Check the Development build option

  4. Build your game

  5. See what the console outputs

outputs 0, but why, arrays have prefabs, they do not reset when the game is turned on in editor, why do they reset after build?

Try to move your prefabs into the "Assets/Prefabs" folder. Maybe they are located in some unexpected folder and as result they do not included into the final build.

Can it happen, that the array is not existing at all? I run into same problems like, you create the variable like this: 'GameObject[] cars', and then the program goes a way where it gets no value at all. since its an array it will let you use the [] call, but throws an exception even for the 0 value.
