Listener Plugin Not Doing Anything

I am making a plugin that will give players effects if they stand on certain blocks. My code is below. It is loading with no errors, and shows in /plugins, but the events are not working, as standing on the specified blocks give me no effect.

I am indeed in a world with the specified name, and I am Op, so I have sufficient permissions.

Any idea what I am doing wrong? I'm somewhat new to Bukkit.

Update! Found an error, fixed it. Code still not working, but I am finding no stacktraces.

Update! It was because I was doing == instead of .equals()! Thanks for the replies.

Code:java

Check that your plugin is being enabled successfully when the server starts.

 

Shadowwolf97 There are no errors, it simply says it was enabled.

 

Strings should never be checked with == in Java. Use equals();

 

Didn't even catch that! Good find. You could also use equalsIgnorCase(); too.

 

Thanks! I knew it was related to that world line, as it worked when I removed it. I'll re-add it, in the proper format!
