Exploding fireworks

How to make smoke particles that go up into the sky 1 block each second and when it goes up 30 blocks it explodes lots of different color ink? Sorry, I would do it but I'm really bad at calculating the math xD

You don't even help at all...

Tell me what i did wrong

Everything.

This isn't helping you neither me.

My way: Create a custom object (Entity) for example:

PHP:

class FireWorks extends Arrow {
}


I did this once when creating Bazooka

I am not trying to create a projectile firework.

It's easier tho. Creating FireWork projectile is easier to calculate colisions, easier manage multi fireworks at once etc.

PHP:

public function onRun($tick) {
  if(alive){ // Don't bother about this
     if($this->y - $this->startY > 30){
        $this->explode();
    } else {
       // Add smoke particle
       $this->y++;
    }
  }
  $this->updateMovement();
}


Is there anyone that can explain good?

Kinda like that but instead I want colorful ink.

Then tune it... -_-

You do it.

What the f*ck was that? He is trying to help you. It's you who need it not he. You just act like an #ass -.-

Profanity. Please remove the f-word.

DUde, I come here because I need help to do it, if I could do it myself, why would I even aks. #Y-U-SO-DUM

It seems that dust particle is the only one with changeable colours and suits your need.

OMG!!!!! I know how to spawn particles. PEOPLE DON'T READ THAT I want to spawn LOTS OF DIFFERENT COLOR DYE/INK when particles reach 30 BLOCKS HIGH!

WTF is dye/ink? You mean those ones that dye wool?

So, look in my initial post i explained you how to make an particle go up 30 blocks. Now if the 30 blocks are reached, you just spawn particles with mt_rand again my (improved) ROUGH DRAFT:
Make repeating task (1 tick) //or all 2 ticks
__construct accepts x y z (start position)
make var (CurrentStartOffset = 0)
onRun:
spawn Particle(x ,y + CurrentStartOffset ,z)
CurrentStartOffset = CurrentStartOffset + 0.1;
if(CurrentStartOffset == 30)
for(100){
spawn Particle(mt_rand(x-2, x+2),mt_rand(y+CurrentStartOffset-2, y+CurrentStartOffset+2)mt_rand(y-2, y+2))
}
