Phaser P2 collisions not working

[robersend]

Hi, i've been working with phaser p2 collision groups and I just can't get this working properly. In my game i have the player, the map, enemies, npcs and fireballs. Well... The player collides with everything, the fireballs and enemies collide with each other but not with npcs or the map. I have an object layer for the map colisions. Here's the code:

  game.physics.startSystem(Phaser.Physics.P2JS);  game.physics.p2.setImpactEvents(true);  enemies.enableBody = true;  enemies.physicsBodyType = Phaser.Physics.P2JS;  enemies2 = game.add.group();  enemies2.enableBody = true;  enemies2.physicsBodyType = Phaser.Physics.P2JS;  enemies3 = game.add.group();  enemies3.enableBody = true;  enemies3.physicsBodyType = Phaser.Physics.P2JS;  npcs = game.add.group();  npcs.enableBody = true;  npcs.physicsBodyType = Phaser.Physics.P2JS;  var playerCG = game.physics.p2.createCollisionGroup();  wallsCG =  game.physics.p2.createCollisionGroup();  var enemyCG =  game.physics.p2.createCollisionGroup();  var npcCG = game.physics.p2.createCollisionGroup();  var fireballsCG = game.physics.p2.createCollisionGroup();  game.physics.p2.updateBoundsCollisionGroup(); walls = game.physics.p2.convertCollisionObjects(map, "colisiones");               for(var wall in walls)        {            walls[wall].setCollisionGroup(wallsCG);            walls[wall].collides(playerCG);            walls[wall].collides(npcCG);            walls[wall].collides(fireballsCG);        }                var arrayPos=[2152, 523,2042, 396,1987, 483,1330,876,1453,942,1432,1043,2352, 1323,2442, 1196,2287, 1283];        for(var i=0; i<3; i++){            var c = enemies.create(arrayPos[2*i] , arrayPos[2*i +1] , 'evilf', 7);            c.name = 'evil' + i;            c.body.immovable = true;            game.physics.p2.enable(c);            c.body.static = true;            c.body.setCollisionGroup(enemyCG);            c.body.collides(fireballsCG);

           c.name = 'evil' + i;            c.body.immovable = true;            game.physics.p2.enable(c);            c.body.static = true;            c.body.setCollisionGroup(enemyCG);            c.body.collides(enemyCG);

           c.body.collides(playerCG);                    }        /*this.npc.body.clearCollision();        varnon.sprite.body.clearCollision();*/ //Hay que descomentarlo y usar overlap                        //npc.body.static = true;

       varnon.sprite.body.collides(enemyCG);        varnon.sprite.body.fixedRotation = true;        varnon.alternar(true);

Any idea on why it isn't working?
