here's the source code of the combos used in my fighting game

[marmotte]

ok, here's the code i used for the combos in my fighting game... too bad it's not a .fla file, but in the last version of super crossover fighter (not online) i had a very strange "bug" (not with the combo system though)...

so here it is, and i hope some expert coders will improve it, why not, mmmhh? ^^
(sure it can be simpler or shorter! ^^)

    // array that will check and record the last key pressed
    LastKeyPressed = new Array();
// function that handle the LastKeyPressed array
    function SortKeyPressed() {
// only the last 8 keys are recorded
        if (LastKeyPressed.length<8) {
// there cannot be two same keys recorded consecutively
            if (CurrentKeyPressed != LastKeyPressed[(LastKeyPressed.length)-1]) {
                LastKeyPressed.push(CurrentKeyPressed);
            }
        } else {
            LastKeyPressed.shift();
        }
    }
    // which key is pressed right now?
    var CurrentKeyPressed;
// function that give a name to the keys pressed
    function ComboHandler_enterFrame() {
        if (key.isdown(UpArrow)) {
            if (key.isdown(RightDirection)) {
                CurrentKeyPressed = "up+right";
                SortKeyPressed();
            } else if (key.isdown(LeftDirection)) {
                CurrentKeyPressed = "up+left";
                SortKeyPressed();
            } else {
                CurrentKeyPressed = "up";
                SortKeyPressed();
            }
        } else if (key.isdown(DownArrow)) {
            if (key.isdown(RightDirection)) {
                CurrentKeyPressed = "down+right";
                SortKeyPressed();
            } else if (key.isdown(LeftDirection)) {
                CurrentKeyPressed = "down+left";
                SortKeyPressed();
            } else {
                CurrentKeyPressed = "down";
                SortKeyPressed();
            }
        } else if (key.isdown(RightDirection)) {
            if (key.isdown(UpArrow)) {
                CurrentKeyPressed = "up+right";
                SortKeyPressed();
            } else if (key.isdown(DownArrow)) {
                CurrentKeyPressed = "down+right";
                SortKeyPressed();
            } else {
                CurrentKeyPressed = "right";
                SortKeyPressed();
            }
        } else if (key.isdown(LeftDirection)) {
            if (key.isdown(UpArrow)) {
                CurrentKeyPressed = "up+left";
                SortKeyPressed();
            } else if (key.isdown(DownArrow)) {
                CurrentKeyPressed = "down+left";
                SortKeyPressed();
            } else {
                CurrentKeyPressed = "left";
                SortKeyPressed();
           }
        }
        // combo's timer
          timer = 0;
     if (LastKeyPressed.length>0) {
            timer++;
        } else {
            timer = 0;
        }
        if (timer>=34) {
            timer = 0;
            LastKeyPressed.shift();
        }
// variable that involve three keys combos (down, down+forward, forward)
        ComboCheckerThree = LastKeyPressed[LastKeyPressed.length-3]+LastKeyPressed[LastKeyPressed.length-2]+LastKeyPressed[LastKeyPressed.length-1];
        }

then, each time you hit a punch or kick key (under key.Down event), the combo combination is checked. if it's corresponding to a combination you specified, then the special attack is launched. if not, normal action.

sure, it can really be simpler. but it works very well for me, try it here:

1,2,3,4 are the punches/kicks
