Why I can't access stuffs more directly?

Code (CSharp):

1. //files have .bytes extension already
2. //example 1: errors in runtime only
3. var s = (TextAsset[])Resources.LoadAll("midi");        //InvalidCastException
4. var s = Resources.LoadAll("midi") as TextAsset[];    //NullReferenceException
5.  
6. //OK
7. var songs = Resources.LoadAll("midi");
8. var s = (TextAsset)songs [i];
9.  
10. //example 2
11. var txtText = GameObject.Find("TxtText").GetComponent<Text>().text;
12. txtText = "abc";    //no error messages but the UI text string didn't change
13.  
14. var txtText = GameObject.Find("TxtText").GetComponent<Text>();
15. txtText.text = "abc";    //OK

 

Yup that's language features, not bugs.

Your second example is an issue with value versus reference types. Google it.

For the first example you should use the generic method. Faster and avoids casting issues.

 

You can use the generic version of LoadAll

Code (csharp):

1. Resources.LoadAll<TextAsset>("midi");

and BoredMormon beat me to it.
Text.text is probably a property aswell, which also means you may or may not have assignment rights to it.

 

Thanks I will learn about these subjects
