Attaching a script at runtime

Question

Hi all,

I would need to add a script to a gameobject based on its name, which is stored in a string. So, for example, if an object called "zombie" enters the field, I have to attach zombie.cs to it.

I was planning on using something like:

 gameObject.AddComponent(gameObject.name);

but I've just realized that this method has been deprecated in Unity 5. Now, the script class can only be specified as a generic class.

One possible workaround would be to create a method that explicitly calls AddComponent with the right type for each possible string, but I was wondering it there's a more elegant solution.

So far I've tried:

         Type script = Type.GetType(gameObject.name);

         gameObject.AddComponent<script>();

and:

 gameObject.AddComponent<Type.GetType(gameObject.name)>();

but they both give different compilation errors.

Any idea?

In Unity 5 There's a non generic version of AddComponent(Type tp) too

 gameObject.AddComponent(Type.GetType(gameObject.name));

Thank you, that's exactly what I needed! The following code, with a check added as a safety measure, is working as expected:

 var scriptAsset = AssetDatabase.FindAssets (cardName);
 if (scriptAsset.Length > 0)
 {
     gameObject.AddComponent(Type.GetType(cardName));
 }
 else
 {
     Debug.Log (cardName + " not supported!");
 }

It's "MonoScript" not "script" now, I don't know why.
