private Component HoverButton(String string) {

return null;

@Override

}
}
So i was trying to make the button invisible and add this:
if (klicks >= 50) {
upgrade1.setVisible(true);
}
to make the button visible as soon as the player hits 50 "klicks" But by doing that the button never turns visible and its like it isnt even there.
So guys, what can i do here? Help would be much appreciated
Just add the component when the condition is reached. Any component added to a visible frame is visible (the property controls all the hierarchy).
First don't add it to the UI, so remove line, so the component will not be visible:
this.add(upgrade1);
Modify the callback for any button that may increase the gold, for example:
klick.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae){
klicks += k;
test.setText("Gold:" + " " + klicks);
if (klicks >= 10) {
GUI.this.add(upgrade1);
}
}
});
Be careful not to make the frame visible until every component have been added at start, so remove the first call to this.setVisible(true) at the beginning of the constructor.
An alternative would be to let the component being visible but make it enable/disable when needed.
