How to change the speed of current running frames at run time.

[Sohail Ahmad]

HI,

 

is there any way to control the game frame speeds at runtime ?

i need to change the speed of "Parallax" frame of the game, that was added when game object initialized.

 

Code Sample

 

this.addParallax(360, 'media/Ground.png', -400); 

 

 

in the above code, i need to change lets say -400 to -300 at runtime.

 

Any help?

 

Thanks in advance.

 

Regards,

Hi,

 

Change your addParallax function to return TilingSprite:

addParallax: function(y, path, speed) {    var parallax = new game.TilingSprite(path);    parallax.position.y = y;    parallax.speed.x = speed;    this.addObject(parallax);    this.stage.addChild(parallax);    return parallax;},

Then you can change the speed with:

var sprite = this.addParallax(360, 'media/Ground.png', -400);sprite.speed.x = -300;

You are great

one more thing i got to know.
 

Gap = game.Class.extend({

    groundTop: 800,

    width: 132,

    minY: 150,

    maxY: 550,

    height: 300,

    speed: -300,

 init: function() {

        var y = Math.round(game.Math.random(this.minY, this.maxY));

        soleGap = this;

        var topHeight = y - this.height / 2;

        this.topBody = new game.Body({

            position: {x: game.system.width + this.width / 2, y: topHeight / 2},

            velocity: {x: this.speed},

            collisionGroup: 0

        });

 

 

how to change the speed of this -300 to -400 at runtime (while playing)

Try:

 

this.topBody.velocity.x = -400;

[Sohail Ahmad]

i need to change this value at outside this .js file

like my method is
 

function UpdateLevel()

{
     this.topBody.velocity.x = -400;
}

 

how to manage this here, because its only accessible within the body of that method.

You need to have access to the instance of Gap class, example:

var gap = new Gap();gap.topBody.velocity.x = -300;

once again thanks for the hint.

i have update this method.

 

spawnGap: function () {            var gap = new Gap();            gap.topBody.velocity.x = GlobalConfig.gapSpeed;            this.addObject(gap);        }

and updating GlobalConfig.gapSpeed value in UpdateLevel() method.

working perfect for me

you are awesome.

Long live man.

Thanks alot.
