New actor property: BloodSprite

[Nash]

This idea has been discussed a few times before this so I thought I'd make a thread for this feature request.

I propose a new actor property that's used to tell the engine what actor to spawn when it bleeds (shot by a hitscan weapon, crushed by ceiling, etc).

Code: Select all

BloodSprite "Gibs"

... would spawn the pool of gibs when you shoot a monster.

This is definitely necessary if you want to make a fiery monster drop chunks of flames, a stone golem dropping chunks of rock or the Revenant and Lost Soul to drop bone chips when you shoot them with hitscan weapons.

Another reason why I think this would be useful would apply for GZDoom use:

I have replaced the Blood actor with a 3-d model in GZDoom. I think it would be impossible to have the model's texture to be colourized the same as the actor's BloodColor. So if you have a Cacodemon that bleeds blue; the blood particles are blue in colour, but the 3-d model that comes out will be coloured red.

Using BloodSprite, I would be able to easily assign different blood actors and therefore different coloured textured models. In the above example's case, I can use BloodSprite "BlueBlood" for the Cacodemon, and in the MODELDEF, define a different model for BlueBlood.

EDIT:

If the above feature does get implemented, the following flag proposal would also be an ideal companion to the feature.

Code: Select all

+DONTTRANSLATEBLOODSPRITE

This flag will tell the engine to NOT translate the custom blood sprite using the actor's BloodColor property.

Here's some advice: Use models where it makes sense. This doesn't.

[sirjuddington]

Yeah I don't see the point in a bloodsplat model The feature itself would be useful though.

[Nash]

Of course it does make sense.

The model is really in shape of flat blood splats since (G)ZDoom does not support floor decals.

[Ryan Cordell]

Ooh. Nice.

[Wills]

Heh, that looks good. Make sure to have monsters drop a lot of blood splats where they fall when they die.

On topic: I agree with the fact this could be a handy feature. Nash already gave good examples, so I won't continue to expound.

[Alterworldruler]

nice example of this requested feature nash

[Xaser]

Nice one there! I didn't even think about using models for that at all... backatcha Graf? Ah nevermind... that was a bit mean, I should probably chill out or something.

Anyway, this would probably come in handy or something. I've been messing around a bit with custom blood types and as it turns out, although I can use the new Replaces keyword to create entirely new blood splats, it doesn't work well when colorizing. I use a similar method to Caligari's puff objects from his Halo mod (or ww-stranger if you will) where the main splat spawns a bit of tiny ones in the air (literally a blood *splat*), however these small ones don't change color when using the BloodColor property (they stay red). I've made custom variants for the Cacos and Barons but I currently have no means of implementing them. So therefore, I strongly support this suggestion.

Added an optional second parameter to A_SpawnDebris and an optional fifth parameter to A_SpawnItem that both do the same thing: If you set it to 1, then the spawned actor will be assigned the same translation table as the actor that called the function.

[Ryan Cordell]

It was even added in the wiki by mself, after reading that added feature, just FYI.

[Nash]

That still doesn't solve the problem of assigning differet blood sprites per actor.

[Grubber]

Adding future features into the wiki is nonsense. They can be changed and the info only confuse people.

That's why there's a lil' note in the page, saying it is for the SVN version only.

[Grubber]

So what's the point of having it there when people can't use it?

[Ryan Cordell]

They can wait until the new ZDoom comes out, or just compile the SVN version.
