Several Issues

[BrokenSkyDev]

I am generally quite new to Phaser and Javascript as a whole and have some issues i need clarifying.

 

Issue 1:

 

Audio in my game, my Ship sound is created and started like this in the create function.

 

shipsound = this.game.add.audio('shipsound');

shipsound.play();

 

and should be stopped when the player collides with the finish.

 

nextLevel: function()

 {

   shipsound.stop();

   powerupCollision = false;

   powerdownCollision = false;

   this.game.state.start("MainMenu");

 

 },

 

But it does not stop and carrys on through to the next state, thoughts?

 

 

 

Issue 2:

 

 

I am currently using multiple states for levels, my first level works fine, not sure if its worth mentioning but i am currently applying velocity to my player in all states in the update function.

 

update: function ()

  {

    //Player velocity

    player.body.velocity.x = 250;

 

When loading into my second state where the player should start at -

 

player = new Player(this.game, 20,50);

 

 

With debug the player starts at around 1461 x position, I have no idea what is causing this issue or how to fix it.

 

If anyone can help in any way it would be appreciated, Thank You!

I don't know for sure, but maybe you're not destroying the player from the previous state before transitioning to the new one? According to the docs, the StateManager will look for a shutDown method for the previous state before starting the next one. Maybe you need to kill the previous player?

 

No idea about the sound one, though, sorry!

Tried adding a shutdown function which i  believe is done like so.

 

shutdown: function()

  {

    player.destroy();

    shipsound.destroy();

    mainText.destroy();

    enemy.destroy();

    speedpowerup.destroy();

    speedpowerdown.destroy();

}

 

 

Still no luck however still spawn about quarter through the next level.

Is this forum dead?

[valueerror]

you don't need to shut down your state..  phaser is doing that for you and clears everything..

 

 

concerning your player position problem it's hard to say without seeing the whole code..   you obviously defined some sort of player class somewhere ??

 

 

@sound..    in the next level there should be NO shipsound or another shipsound or should it just restart the same shipsound? if so you must set forceRestart to true so the next play() call restarts the shipsound

1) Okay, i will fix this.

 

 

My first level seems to be fine so i will just post level 2's code, i stripped it of most functionality to see if something else was causing it , but no.

 

Level 2 Code:

 

BasicGame.level2.prototype =

{

 

create: function ()

  {

    gameStart = true;

 

    //Start Game world Physics

    this.game.physics.startSystem(Phaser.Physics.ARCADE);

    this.music = this.game.add.audio('music');

    shipcrash = this.game.add.audio('crashsound');

    shipsound = this.game.add.audio('shipsound');

    shipsound.play();

 

    //Loading Sprites

    map = this.add.sprite(0,0,'level');

    landingstrip = this.add.sprite(5050,375,'landingstrip');

 

    //Creating a group for the buildings enabling

    buildingGroup = this.game.add.group();

    buildingGroup.enableBody = true;

    buildingGroup.physicsBodyType = Phaser.Physics.ARCADE;

    this.game.physics.arcade.enable(landingstrip);

 

    //Defining the landing strip to be imovable and setting the body size

    landingstrip.body.immovable = true;

    landingstrip.body.setSize(200, 150, 110, 50);

 

    //Generation of Buildings

    var left = 0

    var right = 350;

    for(var i = 1; i < 11; i++)

    {

      left += 400

      right -= 7;

      var Building = buildingGroup.create(left,right,'levelbuilding');

      Building.body.immovable = true;

    }

 

    player1 = new Player(this.game,30,50);

 

    speedpowerup = new SpeedPowerUp(this.game, 900 , 75);

  

    this.game.camera.follow(player1);

    this.world.setBounds(0, 0,5333,800);

    cursors = this.input.keyboard.createCursorKeys();

 

 

 

 

},

 

update: function ()

  {

    //Player velocity

    //player.body.velocity.x = 250;

    console.log("Player" + player1.body.x);

    console.log("Powerup" + speedpowerup.body.x);

 

 

 

    //All of my collisions that are currently possible

    this.game.physics.arcade.collide(player1, buildingGroup, this.collisionHandler, null, this);

 

    this.game.physics.arcade.collide(player1, speedpowerdown, this.powerDownHandler,null,this);

    this.game.physics.arcade.collide(player1, speedpowerup, this.powerUpHandler,null,this);

    this.game.physics.arcade.collide(player1, landingstrip, this.nextLevel,null,this);

 

    //Controls

    if (cursors.up.isDown)

    {

       player1.body.velocity.y = -50;

    }

    else if (cursors.down.isDown)

    {

        player1.body.velocity.y = 50;

    }

    else

    {

        player1.body.velocity.y = 0

    }

 

 

    //If the player has colided with a power up for speeding up

    if(powerupCollision == true)

    {

      powerdownCollision = false;

      player1.body.velocity.x = 300;

 

    }

    //If the player has colided with a power down for slowing down

    if(powerdownCollision == true)

    {

      powerupCollision = false;

      player1.body.velocity.x = 75;

    }

 

},

 

//Handles collisions that would restart the level

 collisionHandler: function()

 {

    shipcrash.play();

    var explosion = this.explosions.getFirstExists(false);

    explosion.reset(player.body.x + player.body.halfWidth, player.body.y + player.body.halfHeight);

    explosion.body.velocity.y = enemy.body.velocity.y;

    explosion.alpha = 0.7;

    explosion.play('explosion', 30, false, true);

 

 

   //These bools are set to this so the speed is reset

   powerupCollision = false;

   powerdownCollision = false;

 

   this.game.state.start("level2");

 

 },

 

//Handles collision with the Speed power up and its cooldown

 powerUpHandler: function()

 {

   powerdownCollision = false;

   speedpowerup.destroy();

   powerupCollision = true;

   this.game.time.events.add(Phaser.Timer.SECOND * 2, this.powerDown, this);

 

 },

//Handles collision with the power down.

 powerDownHandler: function()

 {

   powerupCollision = false;

   speedpowerdown.destroy();

   powerdownCollision = true;

   this.game.time.events.add(Phaser.Timer.SECOND * 3, this.powerDown, this);

 

 },

 

 

//When a powerup is finished (i think this may need to be cut into two functions)

 powerDown: function()

 {

   powerupCollision = false;

   powerdownCollision = false;

 

 },

 

//When landing on the strip Main menu

 nextLevel: function()

 {

   shipsound.destroy();

   powerupCollision = false;

   powerdownCollision = false;

   this.state.start("MainMenu");

 

 },

 

 

quitGame: function (pointer)

  {

this.state.start('MainMenu');

 

}

 

 

};

 

 

I am currently using this Player class:

 

Player = function(_game, _x, _y)

{

  console.log("Creating Player!");

 

  this.game = _game;

 

  Phaser.Sprite.call(this, this.game, _x, _y, 'ship');

 

  this.game.add.existing(this);

 

  this.game.physics.arcade.enable(this);

 

  this.body.collideWorldBounds = true;

 

  this.body.setSize(50, 50, 1, 0);

 

  this.anchor.setTo(0.5, 1);

 

 

 

 

  return this;

};

Player.prototype = Object.create(Phaser.Sprite.prototype);

Player.prototype.constructor = Player;

My game is also hosted here : http://jbwakeham.bitbucket.org/ 

If it makes it easier to understand the issue.

[valueerror]

oh.. first adivse..  upgrade your phaser version to 2.3  --  yours is outdated....

 

do you have a link to your repository on bitbucket..   its much easier to find a bug by just running the code on your own machine

With debug the player starts at around 1461 x position,

what do you mean by   "with debug"  

do you mean it is positioned wrong when you turn on the physics debug body or what?

[BrokenSkyDev]

"console.log("Player" + player1.body.x);"

 

sorry meant console log, tells where the player is currently positioned along x axis.

[valueerror]

ah oke..  i see the logs..   your game is also never stopping.. even if the browser window loses focus

Turns out i needed to zero out the world bounds, before loading into the next state.

out of curiosity..  you "zeroed" out the worldbounds? how?  to get what exactly?

this.world.setBounds(0,0,0,0);

 

It fixed my issue.

[valueerror]

you mean the issue of the wrong x setting for your airplane after switching states... sorry to say that but you should -not- have to do that.. there is something completely odd going on with your setup.. i've never seen this behaviour before and never had problems with unclean state swaps..

but if you found a workaround.. good.. lets just hope that this the only one

just one last question.. did you write the game prototype definition and the rest of the basic strukture on your own or did you build upon a basic code from some tutorial ?

The Prototype definition and structure and rest of the structure was packaged in with my University template as this project is for a module at University.
