Find block in radius

Hello,

I'm trying to search for blocks similar to a block that was placed. I'm using the below code:

Code:

   for (int x = -5; x <= 5; x++) {
      for (int y = -5; y <= 5; y++) {
         for (int z = -5; z <= 5; z++) {
    if(b.getRelative(x, y, z).getType() == Material.STONE_PLATE) {
       event.setCancelled(true);
       p.sendMessage(ChatColor.RED + "You cannot place a plate trap within five blocks of other plate traps!");
    }
}
   }
}

The issue I'm having is whenever I place down the initial block, it's removed. My goal is to check for the similar blocks around that block, and if that block isn't detected, the block can be placed.

 

Code:

 
        int radius = 5;//or whatever you want it to be   
        final Block block = new Location(b.getWorld(), b.getLocation().getX(), b.getLocation().getY(), b.getLocation().getZ()).getBlock();
        final int x = block.getX();
        final int y = block.getY();
        final int z = block.getZ();
        final int minX = x - radius;
        final int minY = y - radius;
        final int minZ = z - radius;
        final int maxX = x + radius;
        final int maxY = y + radius;
        final int maxZ = z + radius;
        for (int counterX = minX; counterX <= maxX; counterX++) {
            for (int counterY = minY; counterY <= maxY; counterY++) {
                for (int counterZ = minZ; counterZ <= maxZ; counterZ++) {
                    final Block blockName = world.getBlockAt(counterX, counterY, counterZ);
                    //do what you want
                    }
                }
            }

That can be simplified to:

Code:

int radius = 5;
final Block block = event.getBlock(); //placed block
for (int x = -(radius); x <= radius; x ++)
{
  for (int y = -(radius); y <= radius; y ++)
  {
    for (int z = -(radius); z <= radius; z ++)
    {
      if (block.getRelative(x,y,z).getType() == Material.STONE_PLATE)
      {
          event.setCancelled(true);
          p.sendMessage(ChatColor.RED + "You cannot place a plate trap within five blocks of other plate traps!");
       }
     }
   }
}

 

I'm still unable to initially place a block. Below is what I have:

Code:

int radius = 5;
final Block block = new Location(b.getWorld(), b.getLocation().getX(), b.getLocation().getY(), b.getLocation().getZ()).getBlock();
        final int x = block.getX();
        final int y = block.getY();
        final int z = block.getZ();
        final int minX = x - radius;
        final int minY = y - radius;
        final int minZ = z - radius;
        final int maxX = x + radius;
        final int maxY = y + radius;
        final int maxZ = z + radius;
        
        for (int counterX = minX; counterX <= maxX; counterX++) {
       for (int counterY = minY; counterY <= maxY; counterY++) {
       for (int counterZ = minZ; counterZ <= maxZ; counterZ++) {
       final Material plate = p.getWorld().getBlockAt(counterX, counterY, counterZ).getType();
       if(plate == Material.STONE_PLATE) {
       // Should only be fired if placing a plate within a radius of an already placed plate
       p.sendMessage("Stone plate detected!");
       }
       }
       }
        }

This doesn't work neither.

Just use your original code, and add a clause to your inner if:

if(b.getRelative(x, y, z).getType() == Material.STONE_PLATE && (x != 0 || y != 0 || z != 0)) {
Then it will skip over the case where x,y,z are all zero (the block you just placed)

 

That worked perfectly! Thank you and the others who provided code.
