hi guys who can help me?(i am a persian boy so ... Readable plzz)

I want a click of a button : enabled a button= true
and a second click : enabled the button = false

i dont know english and i need to help u guys.

What i understand is you want to enable and disable button on mouse click. for that you can do something like this

public Button myButton; // assign this button in the inspector
    void Update ()
            myButton .enabled = !myButton .enabled;

you will need to drag the button from the hierarchy to the inspector. Hope it helps
