AddComponent Confusion

Hey Guys,

I am having some major issues with this. I have made several attempts which I will lay out. I am really looking for a deeper understanding of this.

My code originally looked like this:

Code (CSharp):

1. public EB( string str, GameObject dummy ) {
2.   Action comp = (Action)dummy.AddComponent(str);
3. }

Unity's Auto-Update changes the code to this:

Code (CSharp):

1. public EB( string str, GameObject dummy) {
2.   Action comp = (Action)UnityEngineInternal.APIUpdaterRuntimeServices.AddComponent(dummy, "Assets/EB.cs (18,27)", str);
3. }

However, this throws a warning:
warning CS0618: `UnityEngineInternal.APIUpdaterRuntimeServices.AddComponent(UnityEngine.GameObject, string, string)' is obsolete: `AddComponent(string) has been deprecated. Use GameObject.AddComponent<T>() / GameObject.AddComponent(Type) instead.

I then tried using System.Type.Gettype():

Code (CSharp):

1. public EB( string str, GameObject dummy {
2.   Action comp = (Action)dummy.AddComponent( System.Type.GetType(str) );
3. }

This makes the warning go away but when the function is actually called it throws a warning:
AddComponent asking for invalid type
Anything that tries to reference 'comp' errors out.

The other information I found was that I am supposed to be using something similar to this code:

Code (CSharp):

1. public EB( string str, GameObject dummy ){
2.   Action comp = dummy.AddComponent<[insert_type_here]>();
3. }

However, I need the type to be based off my string..

I seriously hope you can give me more insight on this so I can actually wrap my head around this issue.

Cheers,
Charlie

 

There's some info on that here:

So, it needs the assembly name, because without it it can't tell what type you are looking for.

I did a little googling and testing, and I'm still not entirely sure how to get the assembly names consistently for all types in a uniform way.. If someone wants to shed some light, that would be nice.

Code (csharp):

1.  
2.         //Unity Type
3.         System.Type AudSourceType = System.Reflection.Assembly.GetAssembly(typeof(GameObject)).GetType("UnityEngine.AudioSource");
4.  
5.         //Custom Class Type
6.         System.Type CustClassType = System.Type.GetType ("YourScriptName,Assembly-CSharp");
7.  

 

Hey Steve,

I had read through this already but was having issues with the at runtime component.

Hey NA-RA-KU,

This is very interesting. My classes that I am trying to grab the type for are all based off custom classes so it looks like maybe I would be using the 'Assembly-CSharp' version there?

Hey NA-RA-KU,

That seems to have worked pretty well. Since I knew that all of them were 'Assembly-CSharp's. Thanks! Let me know if you find a uniform version!

Cheers,
Charlie
