globe textue negative id?

[robin]

I don't understand the logic of the negative id texture.

Positive id is straightforward:
 - each id corresponds to a texture, in sequence as they appear in the graphic file.
 - each texture is linked to one or more terrains (which make sense).

But in case of negative id:
 - each id corresponds to what? Is it arbitrary?
 - each "texture" is linked to one or more alienDeployment instead of a terrain. However the deployment can define the terrain itself so: can I skip defining negative id textures altogether?

Likely I'm losing myself in a glass of water.
Thanks.

Pretty much yes, that's the thing about negative textures; that they are not bound to a specific global texture. That's because missions using negative textures are never UFO landings or otherwise taking the global texture to determine mission terrain. Instead, you define a specific region for this mission and link it to the texture.

For a simple example, taken from X-Com Files. There's a mission where you must find and arrest/kill one guy. This is a one-time mission, always spawned in a specific place, so no need to involve global textures. Instead, I did this:

Code: [Select]

globe:
  textures:
    - id: -458
      deployments:
        STR_LO_WO_REFUGE: 100 ### this mission's alienDeployment name

regions:
  - type: REGION_LO_WO_REFUGE
    missionZones:
      -
        - [108, 108, -13.5, -13.5, -458] ### only one location; you can have many if you want. Note the -458 value


alienMissions:
  - type: STR_LO_WO_REFUGE
    despawnEvenIfTargeted: true
    objective: 3
    spawnZone: 0
    raceWeights:
      0:
          STR_BLACK_LOTUS: 100
    waves:
      - ufo: dummy
        count: 1
        trajectory: CA_SPAWN
        timer: 9000
        objective: true


missionScripts:
  - type: loWoRefuge
    firstMonth: 0
    missionWeights:
      0:
        STR_LO_WO_REFUGE: 100
    regionWeights:
      0:
        REGION_LO_WO_REFUGE: 100 ### the region which specifies texture
    useTable: false
    maxRuns: 1
    varName: LO_WO
    researchTriggers:
      STR_BLACK_LOTUS: true
      STR_DOSSIER_LO_WO: true
    startDelay: 20
    randomDelay: 43500

Now I understand, I was missing that fact the texture was linked to the region.
Thank you!
