Projectile's Target

[DBThanatos]

Is there a way to make a projectile recognize as the target for A_JumpIfCloser, the monster's target? Because right now, if a projectile has this funcion, it checks the distance with the shooter (a monsters calling the projectile with A_CustomMissile).

Quick example:

Code: Select all

Actor NewDoomImpBall : DoomImpBall replaces DoomImpBall 
{
	States
	{
	Spawn:
		BAL1 A 0
		BAL1 A 0 A_JumpIfCloser(128,"Death")
		BAL1 A 4 Bright
		Loop
	Death:
		TNT1 A 0 A_Stop
		BAL1 CDE 6 BRIGHT
		Stop
	}
}

And as soon as an imp fires, the projectile will go to the death state. So, it's checking for how close/far is the caller, instead of the real target.
It makes no sense, for example, with a seeker missile, that in theory, it has a real target, and still, it checks for the caller.

In the wiki, I saw about firemode 4, and even though it says that is for projectiles fired by other, I wanted to give it a shot. Not even like that worked.

So, is there a way to do this? And also, could this be considered a bug?

Not as far as I know.

Definitely not. A missile's target is its shooter, this is a non-intuitive, but fundamental, quirk of Doom. A_JIC measures the distance between an actor and its target, so if used by a missile, between the missile and its shooter. Working as intended.*

We could imagine a flag parameter to allow to specify closer to whom -- target, tracer, or master. This would be useful; though keep in mind that a projectile is normally dumb and has no idea what it's fired at, unless it's a homing missile, then it uses its tracer field. So even then, it wouldn't help in your example since this fireball is not homing.

Well, not in this example, but in what Im using it, it's indeed a seeker missile

So, yeah, maybe is time for a feature suggestion
