need help with gzdoom DECORATE

What you need is something more like this:

Actor "Rocketflying" : Rocket 9001
{
  States
  {
  Death:
    MISL B 8 Bright A_Explode
    MISL C 6 Bright
    MISL D 4 Bright A_DropItem ("RocketBall", 1, 255)
    Stop
  }
}

I copied-and-pasted the actual rocket's death state and corrected and added your DropItem line to it.

You need to spawn the item you want to drop in the projectile's death state I believe.

You might be right. I didn't test the code. Maybe A_DropItem doesn't work for projectiles. @Garbage, If it doesn't work, try A_SpawnItemEX, instead.

@Empyre Tested the code, worked great

A_SpawnItemEx will offer more options, but DropItem works fine.
