Holding a keydown...

When a keydown() is used in a timeout it can just be held and it will do the action for you. How do I eliminate this? Just in case I'm not clear since I'm half-delusional from sleep and am not even reading while I type, here's an example:

PHP Code:


		
			
//#CLIENTSIDE



function onTimeOut() {

  if ( keyDown( 5 ) ) {

    foobar;

  }

  setTimer( 0.05 );

}

So, yeah. I just want to know how to make so the player must tap the key to get repeated use out of it.

You need to initiate the timeout first. The only setTimer you have is in the timeout itself, so nothing is telling it to actually start looping. Throw a setTimer in an onCreated.

I know this, I'm just saying the context of it. Obviously, the script is much more than an uninitiated timeout with a keydown() in it :p

Oh, sorry I just read the script.

Anyways the only way to break the repeating function is to keep a flag on the key being hit. You can use onKeyPressed() but that has a repeat function based on default keyboard(after a second or so it'll start repeating).

PHP Code:


		
			
function onTimeout() {
  if (keydown(5)) {
    if (this.keydown5 == true) dostuff();
    this.keydown5 = true;
  } else this.keydown5 = false;
}

I tried this and it didn't work... Although, when I did I combined the two line like this:

PHP Code:


		
			
if ( keyDown( 5 ) && this.keydown5 == false ) {

Would that have anything to do with it?

I also noticed every flag is set to true. Am I missing something there?

No you have to do it exactly as my post says because of the way the nested code works. If you do it like (keydown(5) && this.keydown5 == false) then it won't revert the this.keydown5 back to false since it requires not pressing S AND it being false.

Now it doesn't work at all o_o

PHP Code:


		
			
function GraalControl.onKeyDown(code, key, scan) {
  // if you care about matching default controls, use if (keydown) here
  if (key == "a" && ! this.keyA) {
    player.chat = "tap!";
    this.keyA = true;
  }
}

function GraalControl.onKeyUp(code, key, scan) {
  if (key == "a") {
    this.keyA = false;
  }
}

It's certainly possible to do via timeout, as Dusty instructed, but there's no reason to do so when it can be done using events.

Ah, thanks to all of you. I knew there was a different way aside from timeouts.
Dusty, I got yours to work, I just entered it wrong. Although I had to change a few things around to make it work.
Chris, thank you for this method... Probably a bit more efficient and much cleaner than what I did.

I like the..

PHP Code:


		
			
//#CLIENTSIDE

function onKeyPressed() {

  setTimer(0.05);

}



function onTimeout() {

  if (keydown(5)) {

    doStuff();

    setTimer(0.05);

  }

}

way personally. Depends what you're doing in the end really.
