Cool little Vanilla Doom trick for particle fields

[holaareola]

Comes with limitations: it breaks the IOS (unnecessarily, actually, but I stripped it out of a larger project) and the sectors the particles will spawn in need to have a floor below 0 and a ceiling above 640. This is because the particles use the IOS death explosions codepointer which spawns explosions within a fixed height range. The two teleporters on the left are based at 0, whereas the one background right is lower, and you can see the particles are only spawning halfway up which looks a bit shit.

 

With some custom particle sprites could make for some cool energy fields, steam or hellish rising damned souls.

Do you mean a floor above 0/ceiling below 640?

 

Nice trick!

Hmm, this trick could have an use in some kind of Heretic/Hexen themed vanilla Doom megawad

Intuitively that'd make sense, but because the codepointer works by spawning a rocket (but with P_SpawnMobj instead of P_SpawnMissile) and then setting its state to an unrelated frame, if it's spawned inside the floor or inside the ceiling it immediately explodes.

Hah, was playing a bit of Heretic the other day and that was exactly what made me think of this :)

I had an idea for creating fake rain by having falling objects spawned from invisible things on the ceiling.

Hmm, I think this trick could do that by modifying rockets to have gravity and adding a splash as the death anim. Horrible thought to sacrifice the rocket launcher and cyber though. Unless you also turned the rocket launcher into a water cannon!

This is ingenious! I guess you have to design around it pretty carefully, but it's still a cool way to get a ZDoom-particles-type effect in vanilla with surprisingly little jank.

That's tremendously cool, great work!

Now that looks awesome. I can't wait to see this effect appear in people's maps!

Couldn't help myself! Worth sacrificing a projectile weapon for though? Probably not, unless for perhaps a single mood-heavy vanilla map.

 

//Goddamnit in the edit:  why didn't I do one little sky recolour and some purple rain?

Would like to see something similar to Super Castlevania IV's block 9 with the rising ghosts.

holaareola,

 

Thank you for sharing this feature. I assume since you've provided a link for download, and posted it here on a public forum, I would be permitted to use this effect in my own levels, if in fact the design warrants such a feature, provided that I give credit to you through my TXT file?

Go for it, absolutely. Would love to see what you did with the effect, drop a message in here if you publish the level :)
