how to check wheter placed block is a sign?

hi, how can i check wheter a placed block is sign?
so does it need to be in blocklistener with the blockplace event and if, how to code it?

 

Yes, it would be in your block listener with the block place event
My guess would be this

Code:java

public void onBlockPlace(BlockPlaceEvent e){
      Block block = e.getBlock();
      if(block.getType().equals(Material.SIGN)){
            //Do stuff here
   }
}

 

ill try it

okay i did this now, but i still cant do what i want with it.
may you wanna check the code blockListener

I'm not an expert on sign, but my guess is it's not working because you are looking for the lines when the block is place, in which case there wont be any lines. You could do a SignChangeEvent if there is one. http://jd.bukkit.org/doxygen/dc/d8f/SignChangeEvent_8java_source.html

 

I always use a SignChangeEvent... mainly because it works with events in the future and plays well if the sign is ever changed in a way after placing. You can also get text from a SignChangeEvent... because the event is executed after a sign is placed, So you can get right into your stuff.

Code:

public void onSignChange(SignChangeEvent event) {
        if (event.getLine(0).equalsIgnoreCase("[heal]") {
               event.setLine(0, "[HEAL]");
        }

    }

And so on and so forth...

 

thanks man
