Why are you developing it for API 12/ 1.3.12? PocketMine 1.4 is coming soon!

Mr. Doctor, my leg hurts. But I won't tell you which part of my leg hurts, nor am I going to let you touch my leg.

• Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

This refers to nobody i just like this quote by Albert Einstein

Einstein believes that the universe is neither infinite nor with boundary.

the universe is not infinite according to big bang because it's an explosion from nothingness and it gets bigger and bigger but its not infinite and after about 2*10 billion by the 6 billion power times 100000000 gooogol light years the universe well run out of matter and eventually collapse on it self , and if you are able to watch it out side of the universe you well see it as flash back from the big bang ( i didn't get this info from google i realized that by my self and then asked google for confirmation)

I know all of this "and im not sure about the universe"

Configuration?

I remember it's kind of a 4D circle-like thing, like when you go to the "boundary" you in fact are like traveled round Earth.

With some quotes you can realise that you can get really smart these days .

confirmation sorry

thats how you help people? thanks!

How do you expect Mr. Doctor to help you if you don't tell him what hurts and don't let him even look at you?

This plugin, obviously, is generated through a plugin generator. Also, you handle the event when a player changes his gamemode, and you didn't register the command at all. Moreover, the handler of the gamemode change event does nothing except runs a void command "" as console. This forum is for those who have questions in the plugins they made, not the plugins they generated using the online plugin generator. If you want support for the online plugin generator on this website, please reply to that thread or send a private message to the creator.
