Linecount - the total number of linedefs associated with the sector.

Sectors are stored in WAD files in the following format:Īt level load time, several additional variables are generated for each sector and stored in the internal sector data structure. This is used to give the sector a damaging floor (for things like lava and slime), have the sector's light level change constantly, enable wind or currents or even push the player in a certain direction. Sector type - Special properties of the sector. Used, for example, to alter the sector's ceiling and/or floor height, lighting level or flats. Sector tag - A number that makes the sector a target of the action specified by any linedef with the same tag number. For instance, two squares can be separate and non-contiguous, but still be part of the same sector.Ĭeiling flat - Name of the flat (texture) used on the ceiling of the sector.įloor flat - Name of the flat used on the floor. Unclosed sectors can be used for a few special effects, but under some circumstances they can lead to undesirable results (including crashes).Ī sector does not have to be a single polygon. Sectors should be closed areas, meaning that all the sidedefs that reference a particular sector should make up a closed shape. I've done that and now it's ok.A sector is an area referenced by sidedefs on the linedefs, with variable height determined by its floor and ceiling values. Better off just deleting the offending textures. I think this bug begins when you load a saved file. Hopefully that'll work.Ģnd Update: For anyone who encounters this problem, renaming the textures actually DOESN'T solve it because the bug came back somehow. So now there's no blinking random texture changes, I guess a better solution would be to rename the offending textures something that's still in numerical sequence eg. So i went and erased some of them and renamed a few others to fix this problem which worked initially but after a while my map went nuts. This was happening even though I'd separated all the flats / textures into their separate folders in the pk3. Eg: WFall1 (Jimmytex) kept getting automatically replaced by WFall1 (ultratex). Different textures with the same name but different texture packs were getting mismatched in GZDB. This issue is basically my fault as it's connected to an different problem i had with textures changing colour. And vanilla animations affect all textures that are between the start and end of the animation, so again to use our comparison, if you look at W or F, these letters are 'between' M and O because of the mistaken order (but N isn't).Īfter reading your post I messed around trying this and that for a while but with no luck so eventually i started from scratch and re-extracted all the flats / textures in Slade now it's all back to normal. So instead of MNO, or of ONM given the jumble, you get MOPQRSTUVWXYZABCDEFGHIJKLO. You'll need to wrap around to A once you reach Z. So you start at M, which is incorrectly located, and keep adding letters until you reach O. But our alphabet has been jumbled a bit and is not in the regular order: Suppose you want the substring that starts with M and ends with O.

Here's an illustration using the alphabet. So if you put the last before the first, then the animation cycle will include every single texture in the game except the one in between the last and first, because it'll cycle the long way around, wrapping around once it reaches the end of the texture list. Now, the animation is defined as being 'every texture between FIREWALL (last) and FIREWALA (first)', but the direction in which they cycle is always the same. Suppose you have FIREWALL, FIREWALA, FIREWALB. If the textures aren't in this order, then they will cycle using the long way around. Think also about the default animations! For example, in vanilla, you have the animation FIREWALA, FIREWALB, FIREWALL.
