160:Sector_Set3dFloor (tag, type, flags, alpha, hi-tag/line ID)
The ceiling of the control sector will be the floor of the 3D floor and the floor of the control sector will be the bottom of the 3d floor. The texture used on this line type will be the texture used for the sides of the 3D floor. The height of the 3D floor will be that of the distance between floor and ceiling.
Normally the lighting (including light color) of the control sector is transferred to the volume of the 3D floor (if transparent) and the space below it down to the next lower 3D floor.
- tag: Tag of affected sectors.
- type: The type of 3D floor to create.
- flags: The flags to apply to the 3D floor.
- alpha: Specifies the translucency of the 3D-floor: 0 = invisible, 255 = opaque.
- hi-tag/line ID: If type has the value 8 added to it this will give the control linedef a line ID. Otherwise this parameter serves as a high-byte for the sector tag in order to allow more than 256 3D floor definitions. This parameter is completely unnecessary in UDMF and should not be used in that format.
- 0: Defines a Vavoom-style 3D-floor. See the Vavoom Wiki for further information.
- 1: Defines a solid 3D floor.
- 2: Defines a swimmable 3D “floor”.
- 3: Defines a non-solid 3D-floor.
- 4: If you add 4 to the type the inside will also be rendered. Normally this is only done for liquids. This does not work for the Vavoom type. Using 4 alone is an "undocumented hack type that can be used to patch some missing texture hacks the engine can't detect".
- 16: If you add 16 to the type the visibility rules will be inverted. Monsters can see through solid 3D floors but not through non-solid ones. This does not work for the Vavoom type.
- 32: If you add 32 to the type the shootability rules will be inverted. You can shoot through solid 3D floors but not through non-solid ones. This does not work for the Vavoom type.
- 1: Disables any lighting effects created by this 3D floor.
- 2: Restricts the lighting properties into the area between the 3D floor's top and bottom. Logically this is only useful if the 3D floor is not solid.
- 4: GZDoom only: 'Fog' effect. Fills all 3D floor surfaces with solid color using control sector's fade color. Also tints the view when inside and below this 3D floor, depending on the lighting settings for the 3D floor. This flag is not implemented in the software renderer and currently produces undefined results!
- 8: Ignores the bottom height of the model sector and draws top and bottom of the 3D floor at the model sector's ceiling height.
- 16: Uses a sidedef's upper texture to draw the sides of the 3D floor instead of the transfer linedef's mid texture.
- 32: Uses a sidedef's lower texture to draw the sides of the 3D floor instead of the transfer linedef's mid texture.
- 64: Renders the 3D floor using additive translucency.
- 512: 'Fade' effect. Applies control sector's fade color to the area below this 3D floor.
- 1024: Resets lighting effects created by 3D floors above this 3D floor.
- Sloped 3D floors are not available in the software renderer.
- Sloped translucent 3D floors cannot be defined. They can be either sloped or translucent, not both.
- When making a sloped 3D sector make sure that the control sectors are aligned with the in-game sectors on the editing grid. Odd results may happen if they are not aligned.
- Translucent 3D floors may create glitches in the display of XY-billboarded sprites.
- A same sector cannot have both a 3D floor and a Transfer_Heights effect.
- 3D floors can move up and down by moving the model sector's floor and ceiling. But due to the way the Doom engine is doing this, it does not work for the Vavoom-type!
- Sector damage on the control sector is transferred to the target sectors. TERRAIN-based damage and friction are transferred as well (New from ).
- If the control sector has a fade color, it will be used as the palette blend within and underneath the 3D floor.
