replacing blood splatters

[Hidden Hands]

The doom games obviously spawn spurts of blood when you shoot monsters. How would I go about replacing these with my own? I cannot seem to find definitions or any way to replace them. Can it be done with DECORATE or ZSCRIPT and if so, how would I do this?

Thanks in advance.

This is what i do:

Code: Select all

ACTOR LOSBloodSplatter : BloodSplatter replaces BloodSplatter
{...

In this case:

Code: Select all

ACTOR YourBloodSplatter : BloodSplatter replaces BloodSplatter
{...

This is what i do:

While BloodSplatter is a valid replaceable class, I don't think that's what the OP was asking for.

Hidden Hands, were you asking how to replace decals that show up on walls when you hit monsters, or the blood sprites that fly out?
For decals, you should look how Nash did it.
For sprites, replace the Blood class. BloodSplatter also works, but that one only shows up if hit by a +BLOODSPLATTER projectile.

If I replace the BLOOD class, I'm a little confused about it. Where are the sprites for the blood actually stored? They certainly aren't in the doom WAD right? I also can't find em in GZDOOM either?

[Jarewill]

The blood sprites are indeed in the Doom wads.
They are named BLUDA0, BLUDB0 and BLUDC0.

If you don't need to specify custom behavior, you can just replace the sprites and leave the class alone.

Ah ok, so one last question. In the DECORATE code for BLUD it has this:

Code: Select all

  Spray:
    SPRY ABCDEF 3
    SPRY G 2

What is SPRY? That's a sprite? Because the BLUD sprites are all thats needed I thought but I'm trying to understand it is all.

[Jarewill]

Those are Strife-specific sprites and state, as the wiki says:

If the game is Strife, and damage is greater then 13, it shifts to the Spray state (if it exists), otherwise it adds 2 to the damage check for the previous checks.

If you don't include those sprites, then it won't jump to this state.

Ah ok cool. Thank you for all your help .
