[Code] Flat Bleeding, Without the Fuss

[NeuralStunner]

(G)ZDoom emulates an old rendering glitch used by many maps, in which you leave an upper/lower texture blank, and the flat from the touching sector will be rendered over it. This is less fussy than [wiki]Transfer_Heights[/wiki], having the advantage of ignoring the affected sector's lighting effects (such as color and flicker).

The problem is, A map editor will usually display errors for every instance of a missing texture. Want an error-free flat hack?

Throw this into your [wiki]TEXTURES[/wiki]:

Code: Select all

// Allows maps to use the Flat Bleeding trick without getting editor errors. - NS

Texture FlatHack, 16, 16
{
	Patch "-NoFlat-", 0, 0
	NullTexture
}

Now you simply place FLATHACK wherever you would normally put a blank texture. (G)ZDoom will use it as a null texture, while Doom Builder and the like will accept it as a valid texture. (Although it will probably not render in DB2 either, since it doesn't understand using textures as patches!)

You can do this already without any mods: use AASHITTY as your upper/lower texture, and it'll behave as though the texture is missing entirely.

If you're mapping for Doom instead of Doom II, use AASTINKY instead. Similarly, the first texture in the list for Heretic, Hexen, and Strife will all behave as equivalent to null.

The image will never actually be drawn. This duplicates the behavior of AASHITTY and other special textures.

Did it not occur to you to just try using AASHITTY?

[NeuralStunner]

DB2 still complains that AASHITTY or AASTINKY is not a known texture. (At least it did the first time I tried. Argh.)

Although making your own NullTexture is still helpful for maps/mods not specific to one IWad. (Or making an IWad of your own.)

Similarly, the first texture in the list for Heretic, Hexen, and Strife will all behave as equivalent to null.

For reference.

Hacx has the best one. (AARDVARK!)

I'd rather have DB and GZDoom scream at me, makes me feel tougher.

This is less fussy than [wiki]Transfer_Heights[/wiki]...

Personally, I find using transfer heights less fussy, more logical, easier to remember and easier to implement. I'm not commenting on the suggested method as such, just that I prefer the apparently "fussy" method.

[printz]

I don't really like Transfer_Heights especially in Boom/Eternity where you sink like a rock... I find GZDoom 3d floors a better alternative.

[Enjay]

This is not about using transfer heights to make swimable water but, rather, to use for special effects such as hiding a monster in an invisible pit etc.
