Spawning Falling Sand Without Rounding Coordinates

I'm trying to spawn falling sand blocks with a time of 0. I have falling sand spawning, but the problem is that it "snaps" the coordinates to the block it's in when it spawns. Everything else is working except this problem.

Code:

private FallingBlock spawnInvalidFallingBlock(Location location, Material material, byte data) {
            FallingBlock fb = plugin.getServer().getWorld(world).spawnFallingBlock(location, material, data);
            ((CraftFallingSand)fb).getHandle().b = 0;
            fb.teleport(location);
            return fb;
           
        }
public void run() {
            timer++;
            if (timer > 200) {
                this.cancel();
            }
            if (timer == 0) plugin.getServer().broadcastMessage("Showing HG ANIM");
            double entx = x+0.5;
            double enty = y-0.5+(((float)timer)*.015);
            double entz = z+0.5;
            World w = plugin.getServer().getWorld(world);
            spawnInvalidFallingBlock(new Location(w,entx  ,enty,entz  ), Material.GLOWSTONE, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx-1,enty,entz-1),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx-1,enty,entz  ),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx-1,enty,entz+1),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx  ,enty,entz+1),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx+1,enty,entz+1),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx+1,enty,entz  ),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx+1,enty,entz-1),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
            spawnInvalidFallingBlock(new Location(w,entx  ,enty,entz-1),  Material.OBSIDIAN, (byte)0).setVelocity(new Vector(0d,0.415d,0d));
           
        }
