Okey... Dejame checar eso....

Ok, gracias

No tienes alguna cuenta de github? Es mas facil que te ayuden de esa manera

si, espera

un momento que suvo el código

stop ripping off others plugins! thats the result of being such a pirate. learn php and make ur own! im getting pissed to see people like you.

Take it easy... He is just learning xD if he tries to make something more, I'm sure that everyone will act against him

Joshua, I have 14 years and try to learn from tutorials php programming plugins. I'm not going to throw, but if I jump mistakes, ask to learn from those mistakes

kill the fire while its still small.

I started like you xD but I already had 15 and I learned directly from PocketMine's new API (At that time, the API was still taking form )

That sounds like @PEMapModder xD

@Edgar_SM Ya publique los cambios en Github, cree una solicitud de modificacion para que la veas, aceptala:

iJoshuaHD, sorry for having published an error in your plugin. But I'm not a pirate, and do not want to be a pirate
