Keyboard input delay
Jul 11th, 2009, 2:05am  
Hello everyone, i'm Sengir and i'm new of this forum...I'm going to ask you something about processing...I'm programming an old style videogame, a bidimensional ships shooter, but there is a problem. When I move the ship from left to right or from down to up, pressing two buttons in the same moment, the ship stops itself for a while, and then it continues to move...for movements I use this code:

Code:
if (keyPressed)
    {

      if(keyCode==LEFT)
        foo.moveLeft();
      else if(keyCode==RIGHT)
        foo.moveRight();
      else if(keyCode==UP)
        foo.moveUp();
      else if(keyCode==DOWN)
        foo.moveDown();

    }


where for example foo.moveDown(); is:

Code:
 void moveDown()
  {
    
      ypos +=5;   

  }


there's a way to eliminate that horrible delay from a change direction to another? if someone need the entire code ask me...thank you!

There are several examples on the forum to handle multiple key input, for example at http://processing.org/discourse/yabb2/num_1243835922.html#2 (blindfish's code).
