Regarding a loop and drawing in console mode (etc.)

[User137]

you might get some ideas from. I didn't test any of this:

velocityX:=0;
velocityY:=0;
repeat
  StartTime:=GetTickCount;
  Key:=SomeGetKeyFunction(); // Some function that doesn't stop waiting for press
  // return 0 or something if nothing was pressed.

  case Key of
    VK_LEFT: velocityX:=-1;
    VK_RIGHT: velocityX:=1;
  end;

  ballX:=ballX+velocityX;
  ballY:=ballY+velocityY;
  DrawScene;

  // If drawing and moving would take different amount of time each frame
  // then you may need to control the delay length.
  // So that it runs same speed on all computers.
  DelayTime:=50-(GetTickCount-StartTime);
  if DelayTime>0 then Delay(DelayTime);
until Key = #27;

This is just a quick and dirty delay solution, but it should work decently enough for some simple projects.

My reply seems to be eaten up by forum software, so I'll repeat:

Try

if keypressed then Key:= readKey;

instead of just

 Key:= readKey;

That should fix the issue!

Thanks, guys. I'm moving forward again.
