Droplets - Updated 11/10/2018!

[Josh771]

Droplets: Simulated Blood

Droplets is not a mod intended to simply make your game gorier or to add flashy effects. It's a procedural blood mod that tries to mimic sprays and blood splatters using very basic particles, and it can be adjusted anywhere from Mild drips and squirts to Excessive, gushing sprays. Blood drips from ceilings and makes liquid surfaces, like water, foggy. This is the blood mod for the Doom player that appreciates attention to detail and added visual complexity.

Droplets works with Doom 1 & 2, Heretic, Hexen, and Strife. It's not only for Doom!

On Load Order:
Make sure you load Droplets after any content that replaces monsters or blood effects. If you want to use Droplets but it isn't compatible with your favorite mods, you can always request compatibility here or send me a PM, but I am only likely to make compatibility for largely popular mods and large demands.

That's really good for an addon so small

[Caligari87]

I like this. Ironically, it's actually pretty realistic in the amount of blood spawned, as compared to something like Brutal Doom or Ketchup Mod. Would you consider making it GZDoom-enhanced with the flat-3D floor blood like those other mods? After seeing the possibilities, blood-pool sprites are a bit jarring

[leileilol]

Droplets too vertical in aspect, and also they're very, VERY shiny (don't use pure white!). This feels a lot like Revolution X blood.


also the excess splat sprites on the floor is very reminiscent of Amulets & Armor.

I'd love to do this, and would have in the first place. I might have to look into ways to make those myself (I'd rather not just steal them from ketchup).

Yes, I did make the blood very shiny. It's almost cartoony (ever play Conker's Bad Fur Day?) so I might tone it down a little. And by "vertical in aspect" I assume you mean they fly up too much? I mostly did that so that they would produce the neat spatters on the walls even at some distance. I guess I should maybe have some ranged hitscans that produce directional, high-velocity spatters in addition to the droplets.

plz post video demo too

Aww, I thought it's a mod for Blood.

Anyways, I like this! I like how blood turns into decals on walls! In next version, you should add blood colors (like, blue for Cacodemon, green for Baron...).

That was also my original intention. I know the decals use alpha maps... is there something I'm missing about defining the blood so that it will dynamically change colors? Or do I have to manually redefine the Baron and Caco actors to use a new blood actor?

[TheMightyHeracross]

You have to redefine, but not make a new blood actor. Add Bloodcolor Green or Bloodcolor Blue to the new Hell Knight/Baron and Cacodemon, respectively.

Should that automatically recolor the droplets (.png)? Also, can anyone tell me what kind of software I would use to create the floor decals -- would Blender work? I don't know that it's capable of saving .md3 models... I'm pretty clueless with model formats.

[Caligari87]

There's Blender tutorials for GZDoom models around the forums somewhere, I know several of our folks here use it.

I'll look into it. I'm already quite familiar with the basics of Blender itself, so all I need to know is how to get it into GZDoom.

EDIT: Looks like the Blender scripts for exporting .md3's are obsolete, at least the ones I found. Also the BloodColor property doesn't seem to apply to my blood:

---

Code: Select all

ACTOR BloodSquirt replaces Blood
{
	+NOBLOCKMAP
	+NOTELEPORT
	+ALLOWPARTICLES
	Scale 0.5
	var int user_angle;
	States
	{
	Spawn:
		TNT1 AAA 0
	Spray:
		TNT1 A 0 A_SetUserVar("user_angle", random(0,314))
		TNT1 AA 0 A_CustomMissile("BloodDroplet", random(0,4.0), random(-2,2), random(user_angle,user_angle+45), 2, random(20, 40))
		TNT1 AAAA 0 A_CustomMissile("BloodDrop2", random(0,8.0), random(-4,4), random(user_angle,user_angle+45), 2, random(40, 80))
		TNT1 AAAAAAAA 0 A_CustomMissile("BloodDrop3", random(0,16.0), random(-8,8), random(user_angle,user_angle+45), 2, random(80, 160))
		Stop
	}
}

The above code demonstrates that the actual blood actor itself is an invisible actor that exists for 0 tics and sprays my blood droplet actors in a random direction. I think I may have to create two additional types of blood that use recolored blood if there is no way to make the droplet actors inherit the blood color (and I would be surprised if that were possible).

plz post video demo too

If someone would like to make a video demonstrating the effect of the mod, I'll gladly (learn how to) link it in the OP. I don't have any familiarity with recording gameplay and I may just put up some screenshots of some bloody aftermath.

EDIT: Looks like the Blender scripts for exporting .md3's are obsolete, at least the ones I found.

My modified Blender to GZDoom script works perfectly. It was initially made and tested for 2.66 but it works in every iteration of Blender thereafter. I export models to GZDoom everyday for an on-going project of mine and I have been upgrading Blender everytime a new version comes out. Script remains to work perfectly in every Blender release (I'm at Blender 2.71 at the moment).

If you are having problems exporting something, it's usually one of the several common problems - no object selected, object has no UV coordinates, etc. I can help you figure out what your problem is if you post the .blend file.

You have to redefine, but not make a new blood actor. Add Bloodcolor Green or Bloodcolor Blue to the new Hell Knight/Baron and Cacodemon, respectively.

If you are using projectiles to generate the wall splats, you'll probably be disappointed to find out that at this current moment, there is no way to colourize the generated decals because the projectile does not inherit the actor's blood colour. So you'll always end up having red splats even if you're shooting monsters with coloured blood. I have a similar effect for the new Nashgore rewrite and I wound up with this problem. I have made a feature suggestion though so hopefully it should be possible soon.

If you absolutely need to work around this right now, you can define separate blood actors for the Cacos and Barons and define them as separate BloodTypes... but this is not an efficient way to do it and it won't universally support any blood colour (for every new blood colour that's defined, a new actor has to be made... and there's no way you could anticipate what colours of blood anyone in future is going to make. Too much maintenance needed)

The script I was using I believe is much more out-of-date than this. I'll give it another shot, and then if I have an issue I'll let you take a look at the .blend file.

That's a shame. I hope your suggestion gets some more attention and we see some new translation functionality. Also, can I translate true-color .png sprites in DECORATE? I experimented with it but it didn't turn out correctly at all.

[Nash]

I've never done any translating in ZDoom before (a miracle how I've managed to avoid the feature after all this time heh) but I don't think you can translate true colour PNGs. Only paletted images can be translated. Someone correct me if I'm wrong.
