Summary0000497: FastProjectiles MissileType Trails not spawning at +/- 90 degree pitch.
DescriptionRemember this bug from a while back? It was fixed before... but now it's back...

Missile actors that inherit from FastProjectile and travel at a 90 degree pitch will not spawn their MissileType trails

I'm using GZDoom 2.4.
Steps To ReproduceAim straight up or straight down, and fire a missile that inherits from FastProjectile. This will be most visible in mods like Guncaster or Trailblazer.

- In Guncaster, use the Cauterizer or the Old Dreadful. Aiming completely up or down will just show some smoke trail, but not the ball in the middle (which is the actual MissileType trail).
- In Trailblazer, use the Bitchmaker's STANDARD FIRE MODE. Alt-Fire will fire the projectiles at random angles, which will mean that they will not travel at a 90 degree pitch, so their MissileType trails will spawn. If done properly, you will see nothing but the projectile's impact at the end.
Additional InformationI must reiterate that this issue was an engine bug when it was first brought up.

I cannot remember what it was - but it got broken again by trying to fix the flame strike weapon in the wrong place.

 (Flame strike weapon???)

I see it now says it's resolved... but I keep looking through the recent Git activity, and I don't see anything on a change to the FastProjectile code...

Is it fixed? Does this mean that I can download the latest version and this one will be fixed?

EDIT: Actually... I can probably answer that by just trying it out myself... XD

EDIT 2: No, it's not fixed. Why is this marked as fixed?

I'm guessing it's got something to do with the squiggly thing here?
				if (!(frac.xy ~== (0, 0)) && ripcount <= 0) 
                {
                    ripcount = count >> 3;

                    // call the 'Effect' method.
                    Effect();
                }

It is marked fixed because when I shoot up with the Mage's wand straight up in the air I can see the trail.

Has the fix been added to the newer SVN releases yet?

There are no SVN releases, but the fix should have been in a few devbuilds by now.

I confused the name. I always search "GZDoom SVN" whenever looking for the devbuilds, and it brings up the page of devbuilds.

Anyway, the devbuild I got was from March 29, and it didn't work there. And even as I type this, I can say that I still haven't seen any logs in GitHub announcing that this issue was fixed. I've looked through many, many pages, but I haven't seen anything concerning FastProjectiles.

Thanks for showing me that. I'm going to need to test and see if the newer version doesn't have this issue. If it does, I'll try and post a video.
