Accessing Array

Well, i think you missunderstood my question. Everything up till this point works just fine. I just dont konow how to access alements in the array I created. For example I want to check the value of the “type” variable of a given ball spawned in the level.

I tried something like this: PlayingFiled[0].type

but it returned errors saying that PlayingFiled[0] has to be a class.
