Bedrock walls

I am trying to make a border plugin that generates bedrock walls. Before you comment. It is for 1.7 so I will not use WorldBorder. Any ideas how to do this?

I have a working code, it does generate the walls but the walls height is up to Y 256, I want it to be world.getHighestBlockYAt() + 5. So 5 blocks above surface.

I want it to be like it is on the right side and not the left side.





CODE:

Code:

    public void buildBorderWalls(Material m, int border, World w) {
        Location l = new Location(w, 0, 60, 0);
        for(int x = l.getBlockX() - border; x <= l.getBlockX() + border; x++) {
            for(int z = l.getBlockZ() - border; z <= l.getBlockZ() + border; z++) {
                for(int y = 0; y < w.getHighestBlockYAt(x, z) + 5; y++) {
                     if ((x == l.getBlockX() - border) || (x == l.getBlockX() + border) || (z == l.getBlockZ() - border) || (z == l.getBlockZ() + border)) {
                         Location location = new Location(w, x, y, z);
                         location.getBlock().setType(m);
                     }
                }
            }
        }
    }

 

It worked thanks. But now I ran into another problem. I'm setting the walls to be getHighestBlock + 5, but sometimes it's only 3 blocks high?

Code:

    public void buildBorderWalls(Material m, int border, World w) {
        Location l = new Location(w, 0, w.getHighestBlockYAt(0, 0), 0);
        for(int x = l.getBlockX() - border; x <= l.getBlockX() + border; x++) {
            for(int z = l.getBlockZ() - border; z <= l.getBlockZ() + border; z++) {
                int topY = w.getHighestBlockYAt(x, z) + 5;
                for(int y = 0; y < topY; y++) {
                     if ((x == l.getBlockX() - border) || (x == l.getBlockX() + border) || (z == l.getBlockZ() - border) || (z == l.getBlockZ() + border)) {
                         Location location = new Location(w, x, y, z);
                         location.getBlock().setType(m);
                     }
                }
            }
        }
    }
