Phaser not able to destroy bitmap

[PhasedEvolution]

Greetings. I am trying to do something similar to this: http://codepen.io/photonstorm/pen/ogZJPP?editors=001

However I can't destroy the bmd. I don't know why.

// The bmd wall I will generate. I want to "destroy" it when the bombs hit it

this.wall_bmd = game.add.bitmapData(game_width, game_height);
this.wall_bmd.ctx.beginPath();
this.wall_bmd.ctx.rect(800, 100, 200, 300);
this.wall_bmd.ctx.fillStyle = '#FFA07A';
this.wall_bmd.ctx.fill();

this.wall = game.add.sprite(0,0,this.wall_bmd, 0,map_elements_group);
    
game.physics.arcade.enable(this.wall);
this.wall.body.immovable = true;
this.wall.body.allowGravity = false;
this.wall.body.setSize(200, 300, 800, 100);


// The way I am generating my bombs (I am also having some doughts here...*1)

this.bmd_bomb = game.add.bitmapData(10, 10);
this.bmd_bomb.ctx.beginPath();
this.bmd_bomb.ctx.rect(0, 0, 10, 10);
this.bmd_bomb.ctx.fillStyle = '#ffffff';
this.bmd_bomb.ctx.fill();

this.bombs_group = game.add.group();
this.bombs_group.enableBody = true;
this.bombs_group.physicsBodyType = Phaser.Physics.ARCADE;

for(var x = 0; x < 20; x++) {

   this.bombs_group.bomb = this.bombs_group.create(0,0,this.bmd_bomb);
   this.bombs_group.bomb.name = 'bomb' + x;
   this.bombs_group.bomb.exists = false;
   this.bombs_group.bomb.visible = false;
   this.bombs_group.bomb.checkWorldBounds = true;
   this.bombs_group.bomb.events.onOutOfBounds.add(resetbomb,this.bombs_group.bomb);

}

// My firing bomb function 

 function fireBomb(player_bombs,player_body) {

        var bomb = player_bombs.getFirstExists(false);

        if(bomb) {

            bomb.reset(player_body.x + 30,player_body.y + 20);
            bomb.body.velocity.x = 300;
            
       }

}

// In the game update function I am doing this (It makes the game REALLY slow) I need a better way to refer to each of the bombs that have been fired...

var bombs = this.player.bombs.bombs_group.children;
         for(var x = 0; x < bombs.length; x++) {
            if(bombs[x].x != 0) {
                var bomb = bombs[x];
                bombVsMap(bomb,map_elements_group);
         }
}

// And probably the biggest problem
function bombVsMap (bomb,map_elements) {

        var wall_bmd = map_elements.wall_bmd;

        var bomb_x = Math.floor(bomb.x);
        var bomb_y = Math.floor(bomb.y);
        
        var get_collision_pixel = wall_bmd.getPixel(bomb_x,bomb_y);
   
        if(get_collision_pixel.a > 255) {
    
            wall_bmd.blendDestinationOut();
            wall_bmd.circle(bomb_x, bomb_y, 100, 'rgba(0, 0, 0, 255');
            wall_bmd.blendReset();
            wall_bmd.update(); 
            bomb.kill();

        
        }            
}

. I am not sure if I can use the overlap or the collision phaser functions to handle the bitmap destruction? Or do I have to do it manually like I did to check for "collision" and if so destroy the map and the bullet.

. If I do have to check for collision manually how can I refer to each of the spawned bullets without making the game really slow?

. Also, I have no idea why the wall is not being destroyed... If I console.log(get_collision_pixel) I see always the "normal pixels".

I am with these problems for a few days already... Can someone please give me an hand?

Thank you a lot

Should this:
 

if(get_collision_pixel.a > 255) {

be a greater than? Looks like you probably want get_collision_pixel.a < 255.

Caso this:
 

if(get_collision_pixel.a > 255) {

Ser Maior do que? Parece Que rápido Você provavelmente vai get_collision_pixel.a Querer <255.

Well actually I am not sure about that. Anyway when I console.log the get_collision_pixel I alway get 0,0,0,0.... I don't even notice any change on the properties...
