Check on what material you place block

Hey guys!

i'd like to know how to check on what material a block is being placed
i tried this
public void onBlockPlace(BlockPlaceEvent e){
Player player = e.getPlayer();
Location location = e.getBlock().getLocation();
if (new Location(location.getWorld(), location.getX(), location.getY() - 1, location.getZ()).getBlock().getType() == Material.GRASS);
player.sendMessage("You placed it on grass");
}
}
But it just said "You placed it on grass" wherever i place a block

Mhm
Umm please post code on [code ] brackets to help us read it,
Anyway it is a syntax error, you have an extra semicolon ( next to your if making it practically useles
Also an efficiency tip: don't create a second location object in every block place instead use location.add(0,-1,0) and that will do exay the same without creating the object.

 

You could use this:

Code:

@EventHandler
public void onBlockPlace(BlockPlaceEvent e){
       Block b = e.getBlock().getWorld().getBlockAt(e.getBlock().getX(), e.getBlock().getY()-1, e.getBlock().getZ());
       if(b.getType().equals(Material.WHATEVER)){
               // Do whatever
       }
}

 

wow thanks for the quick response!
And sorry i'm new here didnt know to you could use

Code:

 

@HerobrineHunterH You don't always place a block above another block, you can place them under, or to one side, use BlockPlaceEvent#getBlockAgainst instead

 

Yes but i only want to check for when a block is placed above another
