Animate Code

Hi again, Diego!

I think there's no need to start over.

Would you mind sharing your file?

Hi JC,

Thank you very much for your quick response. I got all the document class issue solved correctly (just as you laid out previously). The problem is that when I reproduce/publish the project I keep getting the same errors:

Multiple errors 1046: Type was not found or was not a compile-time constant: MouseEvent.

When the Main.as class is incorporated come of the previous actions (buttons for navigation between scenes) added to the project no longer seem to work. Is there something I am doing wrong?

Any help will be valuable.

Best regards

Diego

Here is the code from Main.as and actions inserted previously in the project:

Main.as:

package {

import flash.display.MovieClip;

import flash.events.KeyboardEvent;

import flash.ui.Keyboard;

import flash.events.Event; //used for ENTER_FRAME event

public class Main extends MovieClip {

const speed: int = 20; //speed of the snake

var score: int;

var vx: int;

var vy: int;

var gFood: Food;

var head: SnakePart;

var SnakeDirection: String;

var snake: Array;

public function Main() {

init();

}

function init(): void {

//Initialize everything!

vx = 1;

vy = 0;

score = 0;

snake = new Array();

SnakeDirection = "";

//add food to the stage

addFood();

//add snakes head to the stage

head = new SnakePart();

head.x = stage.stageWidth / 2;

head.y = stage.stageHeight / 2;

snake.push(head);

addChild(head);

stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);

stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);

addEventListener(Event.ENTER_FRAME, onEnterFrame);

//ENTER_FRAME listener is attached to main class and not to the stage directly

}

//This function will add food to the stage

function addFood(): void {

gFood = new Food();

gFood.x = 50 + Math.random() * (stage.stageWidth - 100);

gFood.y = 50 + Math.random() * (stage.stageHeight - 100);

addChild(gFood);

}

//this function will reset the game

function reset(): void {

removeChild(gFood);

addFood();

head.x = stage.stageWidth / 2;

head.y = stage.stageHeight / 2;

vx = 1;

vy = 0;

for (var i = snake.length - 1; i > 0; --i) {

snake.splice(i, 1);

}

}

function onKeyDown(event: KeyboardEvent): void {

vy = 1;

}

//collison with stage

if (head.x - head.width / 2 <= 0) {

score = 0;

reset();

}

if (head.x + head.width / 2 >= stage.stageWidth) {

score = 0;

reset();

}

reset();

}

}

//move body of the snake

for (var i = snake.length - 1; i > 0; --i) {

snake.x = snake[i - 1].x;

snake.y = snake[i - 1].y;

}

//changing the position of snake's head

head.x += vx * speed;

head.y += vy * speed;

//collision with tail

for (var i = snake.length - 1; i >= 1; --i) {

if (snake[0].x == snake.x && snake[0].y == snake.y) {

reset();

break;

}

}

//collision with food

if (head.hitTestObject(gFood)) {

score += 1;

removeChild(gFood);

addFood();

var bodyPart = new SnakePart();

bodyPart.x = snake[snake.length - 1].x;

}

//display scores

}

}

}

Navigation actions in the project:

Scene 1:

btn_start.addEventListener(MouseEvent.CLICK, fl_ClickToGoToScene);

function fl_ClickToGoToScene(event:MouseEvent):void

{

MovieClip(this.root).gotoAndPlay(1, "Escena 4");

}

Scene 2:

btn_inicio.addEventListener(MouseEvent.CLICK, fl_ClickToGoToScene_2);

function fl_ClickToGoToScene_2(event:MouseEvent):void

{

MovieClip(this.root).gotoAndPlay(1, "Escena 1");

}

btn_texto_omran.addEventListener(MouseEvent.CLICK, fl_ClickToGoToScene_8);

function fl_ClickToGoToScene_8(event:MouseEvent):void

{

MovieClip(this.root).gotoAndPlay(1, "Escena 4");

}
