Why isn`t this working?

Hi, I`m trying to spawn an Item at a specific location, the item is spawning, but the location is a bit "random", it always spawn 1 or 2 blocks away from where it has to spawn.

Code:

double x = p.getLocation().getBlock().getLocation().getX()+0.5;
                    double z = p.getLocation().getBlock().getLocation().getZ()+2.5;
                    double y = p.getLocation().getBlock().getLocation().getY()+3;
                    Location loc = new Location(p.getWorld(), x, y, z);
                    Item i = p.getWorld().dropItem(loc, Rewards.reward(p, InventoryClick.cpchest.get(p)));
                    i.teleport(loc.getBlock().getLocation());

I want it to spawn at the top of the block that is Z +2 from the player.

There aren`t any crashes, Thanks ^^

 

Change from Next Key to Next Keys

 

haha, that's funny..., I told you that

use getBlockZ() etc iustead of just getZ(). Additionally for the key thing just check if they're waiting on another key before giving them one in the command.
