Error

[Hipst3rKiwi]

hello, i was making a flappy bird clone for school and i keep on getting this error whenever i try to make my pipe functions work

 

1. Uncaught TypeError: Cannot call method 'apply' of undefined phaser.js:39346
   1. Phaser.Timer.updatephaser.js:39346
   2. Phaser.Time.updatephaser.js:38796
   3. Phaser.Game.updatephaser.js:19712
   4. Phaser.RequestAnimationFrame.updateRAFphaser.js:34769
   5. _onLoopphaser.js:34755

 

code:

 

function start() {

    birdSprite.body.allowGravity = true;

    // spawn pipes

    //  Create our Timer

    pipeT = game.time.create(false);

    //  Set a TimerEvent to occur after 2 seconds

    pipeT.loop(2000, pipeS, pipeS);

    //  Start the timer

    pipeT.start();

}

 

function pipeS() {

    //pipeT.stop();

 

    var pipeY = ((game.height - 16 - OPENING / 2) / 2) + (Math.random() > 0.5 ? -1 : 1) * Math.random() * game.height / 6;

    // Bottom Pipe

    var botPipe = makePipe(pipeY);

    // Top Pipe (flipped)

    var topPipe = makePipe(pipeY, true);

 

    // Add invisible space thingy

    var inv = invs.create(topPipe.x + topPipe.width, 0);

    inv.width = 2;

    inv.height = game.world.height;

    inv.velocity = -SPEED;

 

    //pipeT.start();

    pipeT.add(1 / SPAWN_RATE);

}

 

function makePipe(pipeY, flipped) {

    var pipes = create(

        game.width,

        pipeY + (flipped ? -OPENING : OPENING) / 2,

        'pipe'

    );

 

    // Flip pipe

    pipe.scale.setTo(2, flipped ? -2 : 2);

    pipe.offset = flipped ? -pipe.body.height * 2 : 0;

 

    // Move to the left

    pipe.body.velocity.x = -SPEED;    also for some reason im getting a problem with this

 

    return pipe;

}

 

can anyone help?
