Dashing/Running

[[email protected]]

I've been trying to make a running/dashing for the player, I've managed to do it by holding down a key (which is easy) but I found it difficult if you had to press the two keys in a sequence (pushing right x 2 would make the player sprint), has anyone found a way around this?
thanks

I suppose you could add a timer for when the player presses a directional button and give them X amount of time to press it again to be considered a double-tap sprint (would need some type of counter that reads if the player has pressed that button before and then run your checks to see if they pressed it fast enough).

Suggest you record the number of keystrokes for a certain key in a certain time (using a procedure in onTimeout() perhaps?), and clear it when the time is up. In my coding, I have an array of 256 keystrokes, all set to 0. When a user presses the key, the corresponding keystroke in the array is increased by one. Repeat, until the reset time is reached (usually, I go for about 500 ms). To detect if the user pressed the key twice, simply do if (this.keyStrokes[KeyIdentifier] >= 2) { ... }.

Note, this is probably a more complex explanation than Gambet's. Good luck

I'm a bit rusty in my GraalScript, but I created this. It'll give you an idea. Don't critique me on it, I didn't even test it. It should give you an idea though.

PHP Code:

function onCreated()
{
  // The array of keystrokes, of course.
  this.keyStrokes = new[0xFF];
  // How long before the array resets itself.
  this.keyStrokeTime = 500;
  // Don't touch.
  this.keyStrokeLastTime = 0;
}

function onTimeout()
{
  // Yadda yadda
  
  // Check if 500 milliseconds have passed since the last reset.
  if ((timevar2 - this.keyStrokeTime) > this.keyStrokeLastTime)
  {
    // Reset!
    for (temp.i = 0; temp.i < this.keyStrokes.size(); temp.i++) this.keyStrokes[temp.i] = 0;
    this.keyStrokeLastTime = timevar2;
  }
  
  // Check for any keystroke you need for values equal to or above 2.
  if (this.keyStrokes[/* whatever key code you want to check here */] >= 2)
  {
    // Dash code here
  }
  
  // Yadda yadda
}

function GraalControl.onKeyDown(temp.keyCode, temp.keyString, temp.scanCode)
{
  // Adds one keystroke to the array.
  this.keyStrokes[temp.keyCode]++;
}

Zone uses this, right?

function onKeyPressed() {
  for (temp.k = 0; temp.k < 4; temp.k++;) {
    if (!keydown(temp.k)) continue;

    this.("dash_" @ temp.k)++;
    if (this.("dash_" @ temp.k) => 2) {
      player.chat = "Doing Dash!" SPC this.("dash_" @ temp.k);
    }
      //Clear the attempt... this.("dash_" @ temp.k) = null;
    scheduleevent(0.1, "onResetDash", temp.k);
    break;
  }
}

Should work, but the onKeyPressed is being sent about 30 times during this procedure.... x-x

hmm- I mean the keys not mouse. =O

Oh sorry, I have no idea why I posted that o.o

Anyways, onKeyPressed() goes into a loop if you hold down the key if I'm not wrong.

I was thinking of these btw


function GraalControl.

NPC Code:

---

onKeyDown(keycode,keystring,scancode) - a key has been pressed while the control had the input focus (makeFirstResponder())

onKeyUp(keycode,keystring,scancode) - the key has been released 

---

function GraalControl.onKeyDown(keycode) {
  if (timevar2 < this.keydash) {
    if (player.olddir == player.dir) {
      player.movemode = WALKDASH;
    }
  }
}

function GraalControl.onKeyUp() { 
  this.keydash = timevar2 + 0.1;
}

With the movement system I am using, it works a charm. Thanks Chompy =D
