Ok so I want to make it, such that when the block I have is placed, Spawn fireworks(With random variables as lifetime height etc) in a circle(if possible) in a 5 block radius around the block. At the bare minimum, I want the block, when placed, to spawn a bunch of fireworks(random variables if possible).

 

So In order of importance:

Spawn fireworks

--> 5 block radius around the center of the block

----->Fireworks are randomly generated

--------->They spawn in a circle, like spinning. So like 1 spawns in the center, left center, left left center, left, left behind, left left behind, behind etc...

 

Hopefully that made sense, if not, please say why and i will clarify it as best I can.

In onBlockPlacedBy(World,int,int,int,EntityLivingBase), spawn an EntityFireworkRocket.

Find in Entity the methods to set position and such.
