Question by AmasterAmaster · Jul 08, 2015 at 08:51 AM · unity 5scripting problemgameobjectcomponentdynamic

Is there a way to dynamically attach a script to a GameObject during runtime?

What I am looking for is a way to find a script/MonoBehaviour during runtime that can attach to a GameObject as a component dynamically. There could be thousands of these scripts (that is the extreme case), and is noted by an underscore followed by a number (depending on the GameObject used, called "serialNumber" for now). Here is what I have:

 //someObject.AddComponent<"_" + serialNummber>();
 //someObject.AddComponent(typeof("_" + serialNummber));


I get an error saying that this does not work, but is there another way to do this (and I hope I don't have to hard code this by typing in every single serial number through a switch statement, that would be the worst case scenario). Any help is appreciated.

     gameObject.AddComponent(Type.GetType("ScriptName"));

should do the magic.

Alright, I will try that now.

Oh, and it is System.Type. So either put "using System;" or write System.Type

I am getting an error that reads: "error CS1501: No overload for method GetType' takes 1' arguments"

It wants an assembly name, do I pass in the same serial number to both strings? or is that not advised? (So far when I put the same input into both the type name and the assembly name, it seems to work fine, should I worry about any concerns on both names?)

Ok, I changed it to System.Type (sorry if i am a little slow, I need to reload the page more). But I am getting this warning here: "AddComponent asking for invalid type". I am trying to see why it is doing that right now...

Yep, it is solved, thank you very much for the help. The warning was a problem on my side dealing with the scripts being not found, but it is working as expected.
