How to change the variables via Get and set?

I'm trying to understand how do I change the get and set because I'm in trouble.

First Script:

and:

I created the button and have I put the component.
When I click on the object you're the first script it changes to true, but in another class nothing happens.
Why? What should I do?

 

should probably start by looking at the console

This line will be generating a warning for a start

Code (csharp):

1.  
2. private BotaoIniciar construtorBotao = new BotaoIniciar();
3.  

you don't create components like that.

c# is case sensitive
Start
not
start

can you expand on that, "another class"? as in another instance? (think something got lost in the translation here...)


oh and http://forum.unity3d.com/threads/using-code-tags-properly.143875/ not quotations for code please

 

Sorry my quotations =s

There are two different class, I just wanted access to the other var. Because the method OnMouseDown change the var, but, in other class the var not change.
