Using java bufferstrategy and swing elements at the same time -

i program simple rts game now, , first experience in game design. problem when use createbufferstrategy(2) swing elements (buttons etc...) not displayed after bufferstrategy.show(); method invoked. game full of buttons, tables , other crap, , don't want code own. java's layouts, , want make gui on this. so, here little code example, not game, demonstration of problem. thanks. btw, understand source of problem. know swing draw mechanic event-based, while using bufferstrategy not event-based. don't know how solve this. thank you. , final - don't want use default swing event-based approach becouse slow games, , far know bufferstratgey approach games. thx.

you're running infinite loop on swings edt, blocking swing doing anything.

i don't see need bufferstrategy when want display swing elements. combine custom rendering swing components create component renders stuff , add normal layout.

your component overwrites paintcomponent() , draws whatever needs to. can trigger update of component calling repaint() on it. performs enough. note swing components double buffered default, there no need work bufferstrategy there.

if want stick active rendering, call swings rendering chain selectively, example frame's contentpane , call paint() in rendering loop. hacking way may cause unwanted side effects.
