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

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! ^^)

Code:

---

    // 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:
http://www.marmotte.levillage.org/ga...r_fighter.html
1,2,3,4 are the punches/kicks

That's what i'm talking about! Thank you very very much man!

:) :) :)

what does MP and MK stand for? How do you hit?

sorry...
1 = MP (medium punch)
2 = SP (strong punch)
3 = MK (medium kick)
4 = SK (strong kick)
throw: forward+MP when you hit the opponent

that looks awesome man...

Couldn't you replace all of those "SortKeyPressed();" functions from the if statements in ComboHandler_enterFrame() to just one line at the end of them all?

Great game marmotte, can't believe how smooth that is!

Marmotte - How would the function be called from the variable??

Code:

---

if (ComboCheckerThree == updownleftright) {
        _root.test = works;
}

---

??????

RipX

it can be something like:

Code:

---

if (ComboCheckerThree == "down"+"down+right"+"right") {
gotoAndPlay("hadoken");
} else {
gotoAndPlay("normal punch");
 }

---

i know, it's not the best code :-(
maybe i'll end up with something better when i'll re-work on my fighting game, or maybe if someone else's helping...

jonmack
mmmmyes... ^^ but in that case, it will be calculated on each frame even if i don't press any attack key, no? or maybe i missed something ^^

I like:D

Hmmm, Is something wrong with my code?

This is on the main timeline:

Code:

---

// Set variables
speed = 5;
// Set array for cheats
LastKey = new Array();
function SortKey() {
        if (LastKey.length<8) {
                if (CurrentKey != LastKey[(LastKey.length)-1]) {
                        LastKey.push(CurrentKey);
                }
        } else {
                LastKey.shift();
        }
}
// Get current key
var CurrentKey;
// Key Functions
function moveUp() {
        if (hero._y>=5) {
                hero._y -= speed;
        }
        CurrentKey = "up";
        SortKey();
}
function moveDown() {
        if (hero._y<=140) {
                hero._y += speed;
        }
        CurrentKey = "down";
        SortKey();
}
function moveLeft() {
        if (hero._x>=5) {
                hero._x -= speed;
                shaddow._x = hero._x;
        }
        CurrentKey = "left";
        SortKey();
}
function moveRight() {
        if (hero._x<=227) {
                hero._x += speed;
                shaddow._x = hero._x;
        }
        CurrentKey = "right";
        SortKey();
}
 timer = 0;
    if (LastKey.length>0) {
            timer++;
        } else {
            timer = 0;
        }
        if (timer>=9000) {
            timer = 0;
            LastKey.shift();
        }
_root.cheatOne = LastKey[LastKey.length-4]+LastKey[LastKey.length-3]+LastKey[LastKey.length-2]+LastKey[LastKey.length-1];

stop();

This is in a movieclip called actions:

Code:

---

onClipEvent (enterFrame) {
        if (Key.isDown(Key.UP)) {
                _parent.moveUp();
        }
        if (Key.isDown(Key.DOWN)) {
                _parent.moveDown();
        }
        if (Key.isDown(Key.LEFT)) {
                _parent.moveLeft();
        }
        if (Key.isDown(Key.RIGHT)) {
                _parent.moveRight();
        }
        if (_root.cheatOne == "up"+"down"+"left"+"right") {
                _parent.gotoAndStop(2);
        }
}

---

aah, yes. i see. that's probably why your game is smooth running :D Suppose you could put it in some sort of if(keypressed) statement - only one more little check without actually calling function if not needed. Anyway... your code. I like to keep things as compact as i can.

Still can't get over how sweet this game is. I started making a one-on-on fighting game like this a while ago, but gave up very quickly, bit over my league. You've inspired me to at least re-think my plans ;)

ahhhh, these are words i like to hear ^^
what kind of fighting game do you want to create? custom graphics, ripped graphics...?

RipX
mmmh, i suppose your code isn't working? did you trace your array to see the results?

in my case, the code was more like:

Code:

---


onClipEvent (enterFrame) {
        if (Key.isDown(Key.UP)) {
                _parent.moveUp();
        }
        if (Key.isDown(Key.DOWN)) {
                _parent.moveDown();
        }
        if (Key.isDown(Key.LEFT)) {
                _parent.moveLeft();
        }
        if (Key.isDown(Key.RIGHT)) {
if (_root.cheatOne == "up"+"down"+"left") {
                _parent.gotoAndStop(2);
        } else {
        _parent.moveRight();
        }
}

have u people been using any tutorials for your fighting games?

no.

(it's possible i'll prepare an open source though ^^)

mmmhhh... just to let you know, i'm not very motivated for my work today, so...
i'm actively working on an open source! yes!

i already have the basic movments done (directions, jumps, attacks).
the things missing now is a dumb opponent and combos (i'll surely improve the above code)

anyway, i'll put a basic version first i think. stay tuned ^^
