if (klicks >= 50) { upgrade1.setvisible(true); } to make button visible player hits 50 "klicks" doing button never turns visible , isnt there.
so guys, can here? appreciated
just add component when condition reached. component added visible frame visible (the property controls hierarchy).
first don't add ui, remove line, component not visible:
this.add(upgrade1); modify callback button may increase gold, 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 make frame visible until every component have been added @ start, remove first call this.setvisible(true) @ beginning of constructor.
an alternative let component being visible make enable/disable when needed.
