Check if a block is near blocks...?

Hi, so I have a problem.

I need to check if the block TnT is near four iron blocks, and then do something if it is. I have no idea at all, but I'm almost certain someone here would. This is what I mean, in a picture.



Any help would be amazing, thanks!

 

@maxxb123 Use World#getBlockAt with coordinates relative to the tnt.

 

If you know that the TNT block will be placed last - or you only need to check when the TNT is lighted, then this is trivial. If you don't know either of those things, it's slightly more annoying, but still quite doable.

 

Code:

if (tnt.getRelative(BlockFace.SOUTH).getType() == Material.IRON_BLOCK &&
tnt.getRelative(BlockFace.EAST).getType() == Material.IRON_BLOCK &&  tnt.getRelative(BlockFace.NORTH).getType() == Material.IRON_BLOCK &&
tnt.getRelative(BlockFace.WEST).getType() == Material.IRON_BLOCK){
//do stuff
}
