Help - Bulletholes in ceilings and floors

[Niphura]

I saw that this is possible in Brutal Doom, i know that it works with 3d models and some actors like "DetectFloorBullet" or "DetectCeilBullet" but i don´t know what to do with this stuff, someone can help me?

Crack open brutal doom pk3 and take a look yourself. But I dont recommend you doing it in brutal dooms way, since its incredibly hacky...

Is there any other way? i already checked the pk3 but i have no clue on how to make the bulletholes appears in ceilings and floors

[Caligari87]

Very simply: Since we can't have real decals on floors/ceilings, a way to fake it is to use flatsprites or 3D models that look like bullet holes. When the bullet hits a floor or ceiling instead of a wall, it spawns the fake bullethole actor.

I don't know how it is implemented in Brutal Doom, but this is how it's done in Complex Doom:

---

1. First, a gun fires bullets with custom puff:
Weapons.dec:

Code: Select all

SHTF A 2 Bright A_FireBullets(3.8,2.4,7,Random(5,7),"ModdedBulletPuff")

2. Then the puff spawns two actors that check for floor and ceiling (DetectFloorPuff, DetectCeilingPuff).
SFX.dec:

Code: Select all

...
ACTOR ModdedBulletPuff replaces BulletPuff
{
Radius 0
Height 0
Scale 0.75
RenderStyle Translucent
Alpha 0.5
+NOBLOCKMAP
+NOGRAVITY
+ALLOWPARTICLES
States
{
Spawn:
	TNT1 A 0
	TNT1 A 0 A_SpawnItemEx("DetectFloorPuff",0,0,0,0,0,0,0,SXF_NOCHECKPOSITION|SXF_CLIENTSIDE)
	TNT1 A 0 A_SpawnItemEx("DetectCeilingPuff",0,0,0,0,0,0,0,SXF_NOCHECKPOSITION|SXF_CLIENTSIDE)
...

3. Then DetectFloorPuff checks floor, and if it is on floor, spawns an actor that looks like a decal (FloorPuffDecal).
DetectCeilingPuff does the same thing, but for ceiling.

Code: Select all

ACTOR DetectFloorPuff
{
Radius 1
Height 4
+MISSILE
+NOTELEPORT
+NOBLOCKMAP
+THRUACTORS
+MOVEWITHSECTOR
+NODAMAGETHRUST
-DONTSPLASH
States
{
Spawn:
	TNT1 A 4
	Stop
Death:
	TNT1 A 0 A_CheckFloor("FloorPuff")
	Stop
FloorPuff:
	TNT1 A 0 A_SpawnItemEx("FloorPuffDecal",0,0,0,0,0,0,0,SXF_NOCHECKPOSITION|SXF_CLIENTSIDE)
	Stop
	}
}

m8f: Yeah, you have more cleaner way. BrutalDoom uses ACS to furtherly detect what surface is being hit and spawns according puff/effect. Originally I wanted to use something like that, but when I found out how it's done, I dumped it completely - it looks too resource-heavy.

Can you do it on this weapon as a quick example? i tried to do it and now it does not even show the bulletholes in the walls

[m8f]

Can you do it on this weapon as a quick example?

What weapon?

Edit: also, Complex Doom doesn't allow reusing its code. So we can take the idea, but not the code.

}

What does this line mean? SXF_NOCHECKPOSITION|SXF_CLIENTSIDE, it´s necessary to put it if i define a different Actor decal?
Also...how would the Decal actor look like?
