A namespace can only contain types and namespace declarations

Unity Engine
1

Hey I’m trying to create a chat system with an NPC (Non playable character), but Like with my other scripts run into problems I am not qualified to solve (Not enough experience). I followed a tutorial but I get an error message saying:
‘Assets/Script/NPC.cs(1,6): error CS0116: A namespace can only contain types and namespace declarations’

‘Assets/Script/NPC.cs(3,6): error CS0116: A namespace can only contain types and namespace declarations’

and

‘Assets/Script/NPC.cs(7,6): error CS0116: A namespace can only contain types and namespace declarations’

And my Script (C#) is :

bool openChat = false;
void OnMouseClick()
{
openChat = true;
}
void OnGUI()
{
if (openChat == true)
{
//GUI Code here.
}
}

Any solutions?

wheres your class declaration?

public class TestClass: MonoBehaviour
{
      Code goes here....
}

This. We like typing out extra words in C#. If you want a less verbose language try UnityScript. Trouble is the documentation for UnityScript doesn’t have many words in it either.

just wanted to ask if class deceleration is hidden in js how to people use features like class attributes inheretence declaring non classed like structs (globally) and blabla. I feel great that I left js before getting serious :slight_smile:

It’s optionally hidden. You can declare a class in a .js, you just don’t have to.

Okay, So I did this:

public class TestClass MonoBehaviour
{
bool openChat = false;
void OnMouseClick()
{
openChat = true;
}
void OnGUI()
{
if (openChat == true)
{
//GUI Code here.
}
}

(Also Let me know if I did something wrong.)
So I did the method you provided, and I got the following error:

Assets/Script/NPC.cs(2,36): error CS8025: Parsing error

put a Colan : between TestClass and monoBheaviour. this is called inheritance. We take MonoBehaviour the base class of TestClass

Okay I was able to fix my last error! but, I’m Still having a problem with my script, I was able to get the code right by doing this:

public class TestClass : MonoBehaviour
{
bool openChat = false;
void OnMouseClick()
{
openChat = true;
}
void OnGUI()
{
if (openChat == true)
{
//GUI Code here.
}
}
}

But I got the following error:

Assets/Script/NPC.cs(1,26): error CS0246: The type or namespace name `MonoBehaviour’ could not be found. Are you missing a using directive or an assembly reference?

try replacing MonoBehaviour by UnityEngine.MonoBehavior
or put
‘using UnityEngine;’ at the top

But now how do I get my NPC to work? The script is fine, but I don’t know how to get my NPC to chat.

At this point, you should start a new post; you now have a very different question, and all these posts just clutter up the thread at this point.
