Adding a pause game function

programming
1

Hey guys! well, basically the title says it all. I need help in creating a pause game button in my snake game. Ive attempted it myself, but it was just an epic fail.

heres the code on the frame:

stop();
_root.options._visible = false;
//Variables and peice width and height
var unit = 15;
var uwh = 20;
var canMove = false;
var dir = 2;
var score = 0;

//add the keydown listener for when you press space to start
//addpeicelist stores how long your tail is
aPieceList = new Array();
keydown = new Object();

//If the space key is pressed, start the game
keydown.onKeyDown = function(){
if(!canMove) {
if(Key.isDown(Key.SPACE)){
canMove = true;
startGame();
}
}
}
key.addListener(keydown);

//this gets the arrow keys when their pressed, and moves your snake accordingly
k = new Object();
k.onKeyDown = function() {
var k = Key.getCode();
if (k == Key.UP && dir != 2 && canMove) {
dir = 0;
canMove = false;
} else if (k == Key.LEFT && dir != 3 && canMove) {
dir = 1;
canMove = false;
} else if (k == Key.DOWN && dir != 0 && canMove) {
dir = 2;
canMove = false;
} else if (k == Key.RIGHT && dir != 1 && canMove) {
dir = 3;
canMove = false;
}
};

//This adds a peice to the end of your character
Key.addListener(k);
function addPiece() {
var p = this.attachMovie(“piece”, “piece”+aPieceList.length, aPieceList.length);
p._x = aPieceList[aPieceList.length-1]._x;
p._y = aPieceList[aPieceList.length-1]._y;
aPieceList.push(p);
}

//This spawns the food peices in different locations
function moveFood() {
var moveIt = true;
while (moveIt) {
food._x = Math.floor(Math.random()*uwh)*unit;
food._y = Math.floor(Math.random()uwh)unit;
moveIt = false;
for (var i = 0; i<aPieceList.length; i++) {
if (aPieceList._x == food._x && aPieceList._y == food._y) {
moveIt = true;
}
}
}
}

//when you die, this ends the game and deletes everything on the stage
function gameOver() {
delete this.onEnterFrame;
canMove = false;
}

//This function starts th game, sets up your snake, the score, etc
function startGame() {
for (var i = aPieceList.length-1; i>=0; i–) {
aPieceList*.removeMovieClip();
aPieceList.pop();
}
score = 0;
var p = this.attachMovie(“piece”, “piece”+aPieceList.length, aPieceList.length);
aPieceList.push(p);
p._x = 10unit;
p._y = 10unit;
var food = this.attachMovie(“food”, “food”, -1);
var c = 0;
moveFood();
var startingLength = 3;
for (var i = 1; i<startingLength; i++) {
addPiece();
}
this.onEnterFrame = function() {
canMove = true;
tScore.text = score;
for (var i = aPieceList.length-1; i>0; i–) {
aPieceList*._x = aPieceList[i-1]._x;
aPieceList*._y = aPieceList[i-1]._y;
}
if (dir == 0) {
aPieceList[0]._y -= unit;
} else if (dir == 1) {
aPieceList[0]._x -= unit;
} else if (dir == 2) {
aPieceList[0]._y += unit;
} else if (dir == 3) {
aPieceList[0]._x += unit;
}
if (aPieceList[0]._y/unit == 20) {
aPieceList[0]._y = 0;
} else if (aPieceList[0]._y/unit == -1) {
aPieceList[0]._y = 19unit;
} else if (aPieceList[0]._x/unit == -1) {
aPieceList[0]._x = 19unit;
} else if (aPieceList[0]._x/unit == 20) {
aPieceList[0]._x = 0;
}
if (aPieceList[0]._x == food._x && aPieceList[0]._y == food._y) {
score += 1;
moveFood();
addPiece();
}
for (var i = 1; i<aPieceList.length; i++) {
if (aPieceList[0]._x == aPieceList*._x && aPieceList[0]._y == aPieceList*._y) {
gameOver();
}
}
};
}

//This is my attemot at making the game pause. it is an epic phail.
function pausegame (){
canMove = false;
};

and heres the code on the botton:

on(press){
pausegame ();
}

Thanks for your time,
Joseph
