Kill projectiles if player dead?

[DonaldDuck]

I made a custom projectile that orbits the player:

---

Code: Select all

actor flyingimpball : doomimpball
{
  speed 15
  obituary "%o came to close to %k."
  seesound ""
  states
  {
  Spawn:
      BAL1 AB 1 BRIGHT
      BAL1 A 0 BRIGHT A_CustomMissile("flyingimpball",0,0,80,CMF_TRACKOWNER,0)
      stop 
  Death:
      BAL1 A 1 A_Scream
      stop
  }
}

Now my question is:
Is it somehow possible to force the projectile to enter its deathstate once the player dies?
It should also work on a server with more then one player.

I thought i could do it with A_KillChildren but it just works on monsters.

How can i do that?

This might be a little roundabout, but perhaps give the player a token inventory during his death animation, then quickly take it away, and have the projectile look for it with A_JumpIfInTargetInventory? Something like...

Code: Select all

A_JumpIfInTargetInventory("DeathToken",1,"Death")

Does this do what you need it to?

Ok i made this now:

---

Code: Select all

actor flyingimpball : doomimpball
{
  Speed 15
  obituary "%o got too close to %k."
  states
  {
  Spawn:
    BAL1 AB 1 A_JumpIfInTargetInventory("YesIamDead",1,"Death")
	BAL1 A 0 A_CustomMissile("flyingimpball",0,0,80,CMF_TRACKOWNER,0)
	stop
  Death:
    BAL1 A 0
	stop
  }
}

actor doomplayer2 : doomplayer replaces doomplayer
{
  states
  {
  Death:
    PLAY A 0 A_GiveInventory("YesIamDead",1)
	goto Death1
  }
}

actor YesIamDead : Inventory
{
  inventory.amount 1
  inventory.maxamount 1
}

But it wont work.
I guess the problem is that the projectiles target is not the player.

Have it check the tracer field instead which would have the player targeted by default

A_JumpIfTargetInLOS ("DoomPlayer", 0, JLOSF_PROJECTILE)

This is not perfect, since it will only work with projectiles that can see the player, as well as projectiles that are shot at the player and not another monster from infighting

[Ed the Bat]

Yeah, I was a little concerned that it might not work since I didn't really know the method that spawned the projectile, so I wasn't sure if the player was their target...

A_JumpIfTargetInLOS ("DoomPlayer", 0, JLOSF_PROJECTILE)

Um, no. That's not what the "projectile" flag does at all. That's related to seeker missiles and entirely useless for tracking the firer whatsoever. (Unless by some hackery the missile is seeking its firer, but that'd require knowledge of pointers enough to make it moot.)

[FDARI]

When an actor has been spawned by a missile function, it will normally assign the firing actor (player, in this case) to its TARGET-pointer. The projectile should then be able to check for a living player like this:

Code: Select all

somestate:
MISL ABAB 2
// the next line is the one that checks target situation
MISL A 0 a_jumpIfTargetInLOS("somestate", JLOSF_NOSIGHT|JLOSF_DEADNOJUMP)
death:
(...)

Nosight: Jump even if the target is not in sight. Deadnojump: Don't jump if the target is dead. So it jumps as long as the target is alive, returning to "somestate". Make sure that some time (at least 1 tick) passes between the "somestate"-label and the jump command, since there will otherwise be a 0-tick infinite loop.

Hey thanks guys it worked!

But the only problem now:
When the projectile orbits the player, it orbits its viewheight and its annoying (can barely see something).
I tried to lower the orbit height by lowering the spawnheight of A_FireCustomMissile to -32, but it goes back to the viewheight!

Next thing i tried was to lower the pitch in A_CustomMissile, so the it would be forced to keep a certain. But it keeps going back to the viewheight AGAIN.

How do i keep the projectile on a certain height? (e.g.: always 16 below the viewheight.)

[Xtyfe]

The viewheight of the player is chest level, and by default that is where the projectile would spawn. I think thats whats happening
