Question

ButtonAction is a function of a script..

LinkedObj.GetComponent("Int_" + LinkedObj.name).ButtonAction(); //Calls Int_Object's ButtonAction function

As you see.. I MUST use the string parameter of GetComponent but I need to make it work on Android. All the loop-holes were using the Type parameter instead of String. I need a way to get it work as a string or convert ("Int_" + LinkedObj.name) into a component type.

Unity doesn't support dynamic typing when porting to Android. If you're planning to go mobile, you should always include #pragma strict at the top of your JS files. I'd personally recommend doing this, anyway.

Quick and dirty solution: SendMessage():

LinkedObj.SendMessage("ButtonAction");

If you're interested in object-oriented programming, it offers a simple and performant solution: create an abstract "button" class with a virtual ButtonAction() method, so that you can create a variety of buttons which each do different things but can all be activated in the same way:

LinkedObj.GetComponent(MyButtonParentClass).ButtonAction();

Thank you. What is the reason for using #pragma strict? Also, I do know a good amount on OOP. I learned a lot about it when I created an RPG in MS Visual Studio's Visual Basic when I was younger. Also the button isn't like a gui button, its a activation button in-game like a swtch or lever. But that clas idea should still work but its not what I'm aiming for, I read more into that SendMessage method and it will work fine for using any linkedobj ill be using. Again thank you.

#pragma strict forces the compiler to treat your code more carefully -- for example, you'll get more warnings and errors when you access variables or functions that don't exist. Sometimes this can slow down your development a bit, but it can also catch problems that would prevent you from deploying to other platforms.

In particular, dynamic typing is disabled when you're in strict mode.
