Chat Plugin help??

I was wondering if anyone knows how to make it where a person types a certain command and it spams the chat and spams noise... Like in this video



The Sounds/Noise (Ghast and trapdoor) could also be heard by other players..Anyone know how?
I wanted to make it just like that.. If someone knows how to do this please help?

-Thanks!

 

Create a shedule task (about ~4 ticks), then check if someone types the command, if yes, then do stuff

EDIT:
To play the sound to everyone simply do for loop of all players on the server and play them the sound

 

Create a void in it a schedule, The scheduler should be 4 ticks, Create another scheduler to stop it. Run both voids when the player sends the command and has sugar in his hand.

 

How would i go about adding ticks? and a scheduler? Also anyone know the sound for the Ghast and trap door opening? I cant seem to find them . I am a little new to making Plugins.. Thanks for your reply and please help?

 

Please take a look at Scheduler programming for the scheduler , Type in

Code:

Effect.

And if you're using Eclipse or Inteli It should tell you all the sound effects.

 

Can you guide me through on how to do this? Im new to Plugin making and need some help.
