Problem: Phaser 2.5.0 physics.p2.setBoundsToWorld not working [SOLVED]

[erest0r]

Hello again, i'm having a problem with my p2.body, it always goes off screen even setting world bounds, besides i'm using a tilemap (my p2.body isn't part of the tilemap), here is my code:

 

module Ark_Annoying {
	export class Game extends Phaser.State {
		cursors: Phaser.CursorKeys;
		player: Phaser.Sprite;
		map: Phaser.Tilemap;
		level1: Phaser.TilemapLayer;

		create() {
			this.map = this.game.add.tilemap("level1");
			this.map.addTilesetImage("blocks_tileset", "blocks");

			this.level1 = this.map.createLayer("layer1");
			this.level1.resizeWorld();

			this.player = this.game.add.sprite(this.game.world.centerX, this.game.world.height - 24, "player");
			this.player.anchor.setTo(0.5, 0.5);
			this.game.physics.p2.enable(this.player);

			this.game.physics.p2.setBoundsToWorld(true, true);

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

		update() {
			this.player.body.setZeroVelocity();

			if (this.cursors.left.isDown)
				this.player.body.velocity.x = -500;
			else if (this.cursors.right.isDown)
				this.player.body.velocity.x = 500;
		}
	}
}

I followed instructions in this link http://www.html5gamedevs.com/topic/5575-p2-not-colliding-with-world-bounds/  but it didn't work.

I'll appreciate your help.

 

I found this solution: I was calling  this.game.phsycis.startSystem(Phaser.Physics.P2JS) in my Boot state, and changed to Game state, and started to work.

Can somebody explain me why is this behaviour?
