your problem comes setup of text , buttons.

the buttontextchange component on buttontext object. can see on picture object has no child. run:

void start () {     buy = transform.findchild("text").getcomponent<text>(); } 

which getting error. text object under button object pass in onclick call.

public class buttontextchange : monobehaviour  {     public void clicked(text textref)     {         debug.log("button buy clicked!");         textref.text = "i button!";     } } 

then in inspector drag text object parameter slot.

edit: user wants change button color on click:

public class buttontextchange : monobehaviour  {     public void clicked(gameobject buttonobj)     {         debug.log("button buy clicked!");         text text = buttonobj.getcomponentinchildren<text>(true);         if(text != null){             textref.text = "i button!";´         }         image image = buttonobj.getcomponent<image>();         if(image != null){             image.color = newcolor;          }     } }
