Solved Iterate through each block in a region

Hi guys,

Say if I had two locations.

How do I interate through the both locations in a region to check to see is each block the same?

I want to select a region and check to see within that region selected are there only wall signs.


Frank.

 

Loop through two locs:

Code:java

 
Location loc1 = new Location();
Location loc2 = new Location();
int x = loc1.getBlockX();
int y = loc1.getBlockY();
int z = loc1.getBlockZ();
int maxX = loc2.getBlockX();
int maxZ = loc2.getBlockZ();
 
for(int x1 = x; x1 < maxX; x1++)
{
    for(int z1 = z; z1 < maxZ; z1++)
    {
        Location loc = new Location(x1, y, z1)
        //Do what you want
    }
}

 

Did you completely forget the Y-axis?

 

yep that would explain why it doesnt work lol

does not work.

 

You have to use your own Locations, not new Location(). In this case they are any two corners of the region. Then you have to find the minimum and maximum vectors from those, then iterate over all three axis like so:

Code:java

 
Location point1 = <yourfirstlocation>;
Location point2 = <yoursecondlocation>;
Vector max = Vector.getMaximum(point1.toVector, point2.toVector());
Vector min = Vector.getMinimum(point1.toVector(), point2.toVector());
for (int i = min.getBlockX(); i <= max.getBlockX();i++) {
  for (int j = min.getBlockY(); j <= max.getBlockY(); j++) {
    for (int k = min.getBlockZ(); k <= max.getBlockZ();k++) {
      Block block = Bukkit.getServer().getWorld(<worldname>).getBlockAt(i,j,k);
      // do what you want because a pirate is free
    }
  }
}

 

mythbusterma Yes I forgot the Y-axis because I copied this code from my project I am working on which doesn't need the Y-axis. Also I don't see why new Location() wouldn't work?

 

Because new Location() is a blank location not guarenteed to be in any particular place, you have to make it the specific points your looking for (that was more of a pointer to him, as it does work just fine for example code).

 

Thank you! here is my solution for what I want guys:

Code:java

    public boolean isWallSign(Block block) {
 
        if(block.getType().equals(Material.WALL_SIGN)) {
            return true;
        }
        return false;
    }
 
    public boolean isRegionAllWallSigns(Location pos1, Location pos2) {
        String world = pos1.getWorld().getName();
        int totalBlockCount = 0;
        int totalSignCount = 0;
 
            Vector max = Vector.getMaximum(pos1.toVector(), pos2.toVector());
            Vector min = Vector.getMinimum(pos1.toVector(), pos2.toVector());
            for (int i = min.getBlockX(); i <= max.getBlockX();i++) {
                for (int j = min.getBlockY(); j <= max.getBlockY(); j++) {
                    for (int k = min.getBlockZ(); k <= max.getBlockZ();k++) {
                        Block block = Bukkit.getServer().getWorld(world).getBlockAt(i,j,k);
                        if(isWallSign(block)) {
                            totalSignCount++;
                        }
                        totalBlockCount++;
                    }
                }
            }
 
        if(totalBlockCount == totalSignCount) {
            return true;
        }
 
        return false;
    }
