[SOLVED] Death.Sky won't work?

	Death:
		TNT1 A 0 A_RemoveChildren(1,RMVF_EVERYTHING)
		PEXP ABCDEFGHIJKLM 2 bright A_FadeOut(0.07)
		stop
	}
}

This projectile won't enter its Death.Sky state. I know because the flare it spawns doesn't disappear, so A_RemoveChildren is never executed.
If I give it +SKYEXPLODE, it'll enter its regular Death state.
What am I missing?

SKYEXPLODE flag needs to be set on the projectile for it to enter Death.Sky.

I know because the flare it spawns doesn't disappear, so A_RemoveChildren is never executed.

With the above flag set, in the Death.Sky state sequence, temporarily replace (or just add) A_RemoveChildren with A_PrintBold("Test") and give it a try. Do you see "Test" printed on the screen when the projectile hits the sky?

There's really no need for that because when I put +SKYEXPLODE I can absolutely clearly see that the regular Death sequence is executed: it shows the Death state animations (which simply aren't present in Death.Sky, so it'd just disapper). Which, according to you, is not what should happen.

Code: Select all

if (onsky || (line != NULL && line->special == Line_Horizon))
	{
		if (!(mo->flags3 & MF3_SKYEXPLODE))
		{
			// [RH] Don't explode missiles on horizon lines.
			mo->Destroy();
			return;
		}
		nextstate = mo->FindState(NAME_Death, NAME_Sky);
	}

This snippet of code from GZDoom's source shows you need SKYEXPLODE set or the missile will just disappear.
You're either doing something wrong, or the version you're using is too old to have this. The "Death.Sky" state seems to have been added at around GZDoom 3.0.

Okay, I see what the problem is. The version I was shooting was actually not the one that I posted but a similar version which inherits from FastProjectile instead (to make use of its MissileType feature). And FastProjectile won't recognize Death.Sky state, invariably going into regular Death instead (if +SKYEXPLODE is present).

I don't quite understand this behavior though. Isn't FastProjectile built on regular projectiles? Why wouldn't it use Death.Sky?

[Blue Shadow]

FastProjectile has its own movement code. It looks like when the Death.Sky feature was added, FastProjectile was left out.

All right, I guess I'll have to go for a workaround. Thanks.
