Making the fusetimers on items exploding at [0, 0] like the spawning items (before the battle starts on theory).

Done.

[0, 0] is already reserved for "explode after first player turn"
[-2, -2] can be used for "explode before battle"

Sequence of events:
1. first, power sources explode -- they can destroy items used in phase 2 and 3
2. then, non-spawning grenades with fuseTimers [-2, -2] explode -- they can destroy items used in phase 3; they cannot (accidentally) destroy themselves (phase 2)
3. lastly, spawning grenades with fuseTimers [0, 0] explode/trigger

Currently "before battle" means only before mission stage 1.
(If multiple mission stages support is needed, write here, and give a reasonable example.)

Ruleset sample:

Code: [Select]

ufos:
  - type: STR_MEDIUM_SCOUT
    battlescapeTerrainData:
      name: UFO_110
      mapBlocks:
        - name: UFO_110
          items:
            STR_GRENADE:
              - [5, 0, 0]
              - [5, 2, 0]
              - [6, 6, 0]
          fuseTimers:
            STR_GRENADE: [-2, -2]   # -2 = mapblock grenade to explode before battle
          width: 10
          length: 10
      mapDataSets:
        - BLANKS
        - U_EXT02
        - U_WALL02
        - U_BITS

Not tested much.
Help with testing appreciated.
