java - Convert class implements ActionListener into thread -


i have simple 2d game class looks like:

public class game extends jpanel implements actionlistener {     private timer timr;      public game(){         //other stuff         timr = new timer(10, this);         timr.start();      }     //other methods including actionlistener-related ones }

and instead of using timer() timing want run game thread, how can , keep actionlistener functions?

don't tie ui other game components. need have separation of concerns. consider having class holds representation of things in game, game state. ui should concern drawing current game state. game should run in loop updates game state, renders ui.

class game() {    world world; //holds state of things in game   ui ui;   long time;   long elapsed; //number of ms since last update    maingameloop() {      time = system.currenttimeinmillis();      while (gamerunning()) {       elapsed = system.currenttimeinmillis() - time;       time = system.currenttimeinmillis();       world.update(elapsed); //updates game state       ui.render(world);      //draws game state screen     }    } }

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
