Player Position 1.7.10

[UrsOsprey]

EntityPlayer player = (EntityPlayer) event.entity;

 

int posX = (int) Math.floor(player.posX);

int posY = (int) Math.floor(player.posY);

int posZ = (int) Math.floor(player.posZ);

 

if (player.inventory.getCurrentItem() != null) {

     if (player.inventory.getCurrentItem().getItem() instanceof Item) {

          player.worldObj.setBlock(posX, posY + 5, posZ, block);

     }

}

 

When I use this code, it places 2 blocks above my head when I'm grounded, but when I fly, it places 2 blocks above my head with a block of air in between. Is there any way I can get the coords of my feet or something to return a more stable Y value? Thank you!
