Scoreboard Timer Error

Hi i'm trying to make Enderpearl delay plugin with the time left in scoreboard :
I used this tutorial: http://bukkit.org/threads/tutorial-how-to-create-a-scoreboard-countdown.175234/

Error: http://pastebin.com/MQLAP6Rq
My main class : http://pastebin.com/jdb8HQ9B
My EnderpearlListener : http://pastebin.com/EzhqL2bL

Thanks in advance !

 

I wonder what caused it.....perhaps something was null....on line...54, perhaps?

What could be null here? Perhaps it was the variable you initilized to null in yoru main class?

In short, learn Java before you try to write a Bukkit plugin, and read this thread: http://bukkit.org/threads/how-to-re...ubleshoot-your-own-plugins-by-yourself.32457/

Here's where you learn Java: https://docs.oracle.com/javase/tutorial/

 

Even though straight from the source is the best you can get, sometimes I perfer visual and auditory in the form of a video: https://www.udemy.com/java-tutorial/#/lecture/135303
Although sometimes I wish the intro was dubstep instead of classic, Don't judge me.

 

I learn java by watching pogostick videos and analyse all codes on this forum...

That's not how you learn Java. You learn Java here: https://docs.oracle.com/javase/tutorial/
