Arrow Key Controls are JUMPY!
Mar 3rd, 2009, 4:39am  
I'm using arrow key controls and they are very jumpy because the operating system only recognizes the key as being pressed continually after a few seconds, so I cannot get smooth movement on the screen via the arrow keys.  Is there a special command to achieve this?  I remember from AS2 it was something like if( key.isDown(key.UP)){ etc...

I'd really appreciate the help!

Here is a snippet of code that I have so far:

void keyPressed(){
 if(key == CODED){
   if(keyCode == RIGHT){
     //move sprite to the right, or something of the sort
   }
 }
}

Thanks for reading,

boolen _right = false;
void keyPressed(){
 if(key == CODED){
   if(keyCode == RIGHT){
     _right = true;
   }
 }
}
void keyReleased(){
 if(key == CODED){
   if(keyCode == RIGHT){
     _right = false;
   }
 }
}

void draw()
{
if(_right){
//move sprite to the right, or something of the sort
}
}
