game.rnd.pick sometimes generate wrong number

[Jirka1111]

In update function:

 

platformsCreate: function() {        // platform basic setup        this.platforms = this.add.group();        this.platforms.enableBody = true;        this.platforms.createMultiple( 10, 'pixel' );        // create the base platform, with buffer on either side so that the hero doesn't fall through//        this.platformsCreateOne( -16, this.world.height - 16, this.world.width + 16 );        // create a batch of platforms that start to move up the level        for( var i = 0; i < 9; i++ ) {            this.platformsCreateOne( this.platformsPosition(), this.world.height - 150 - 150 * i, 50 );        }    }

platformsPosition:

 

platformsPosition: function(){        return Phaser.Math.getRandom([56, 127, 198, 269, 340, 411]);            },

Other methods:

platformsCreate: function() {        // platform basic setup        this.platforms = this.add.group();        this.platforms.enableBody = true;        this.platforms.createMultiple( 10, 'pixel' );        // create the base platform, with buffer on either side so that the hero doesn't fall through//        this.platformsCreateOne( -16, this.world.height - 16, this.world.width + 16 );        // create a batch of platforms that start to move up the level        for( var i = 0; i < 9; i++ ) {            this.platformsCreateOne( this.rnd.integerInRange( 0, this.world.width - 50 ), this.world.height - 150 - 150 * i, 50 );        }    },        platformsCreateOne: function( x, y, width ) {        // this is a helper function since writing all of this out can get verbose elsewhere        var platform = this.platforms.getFirstDead();        platform.reset( x, y );        platform.scale.x = width;        platform.scale.y = 16;        platform.body.immovable = false;        return platform;    },

 

 

 

I had to generate platforms in some predefined x coordinates. But sometimes the platform just won't shows up.

Nobody?

Seems to me (in the 2.1.3. phaser version at least) that it never picks a wrong number:

You can go as high as you like with the amount of checks or run it as often as you like,

 

I could not get it to return a number that's not in the array of numbers to pick from.

Try putting a debug print (like console.log()) in platformsCreateOne() to see where all the x,y coordinates are.  Then work backwards from there.  Also, check your assumptions for this.world.width and this.world.height (with another debug print) to make sure everything is as you expect.

 

And just in case...

Try putting an assert, debug print, or similar after this line to make sure nothing surprising is happening:

var platform = this.platforms.getFirstDead();
