Occlusion culling with a tilemap

[devx123x]

I have a tilemap with two layers. How can I make sure only the tiles that are visible are being rendered? If a tile on the first layer is covered completely by a tile of the second layer, I don't want to render it. But some tiles on the second layer do not completely cover the tile below them. Anyone have some code samples?

I use multiple layers to do that, All you need to do is just hide it using layer1.visible = false;
My code:

if(player.body.x > 5500 && player.body.y < 6720) {
    world_Map_2_layer.visible = true;
    if(player.body.x > 6900) {
      world_Map_1_layer.visible = false;
    }
}

if(player.body.x < 6900) {
  world_Map_1_layer.visible = true;
  if(player.body.x < 5650) {
    world_Map_2_layer.visible = false;
  }
}
