Lua "if...then"语句不响应

以下是代码：

function onMissionStart()
  OFP:showLetterBoxOsd(false);
  OFP:allowPlayerMovement(true);
  OFP:allowPlayerFire(true);
  OFP:setObjectiveState("Wave1","IN_PROGRESS");
  OFP:setObjectiveState("Wave2","IN_PROGRESS");
  OFP:activateEntitySet("enemy1");
end

function isAlive()
  if OFP:isAlive("enemy1") == (false) then
    OFP:activateEntitySet("enemy2");
  end

  if OFP:isAlive("enemy2") == (false) then
    OFP:setObjectiveState("Wave2","COMPLETED")
    OFP:missionCompleted()
  end
end

EventScripts =  {
    onAllPlayersDead = 0,
    onArriveAtWaypoint = 0,
    onCmdCompleted = 0,
    onDeath = 0,
    onDespawnEntitySet = 0,
    onDespawnEntity = 0,
    onDismount = 0,
    onEnter = 0,
    onEnterRVPoint = 0,
    onFirepowerKill = 0,
    onHit = 0,
    onIdentified = 0,
    onIncap = 0,
    onLand = 0,
    onLeave = 0,
    onMissionStart = 0,
    onMobilityKill = 0,
    onMount = 0,
    onMultiplayerMissionLoaded = 0,
    onNoAmmo = 0,
    onNoAmmoAll = 0,
    onObjectDamage = 0,
    onObjectiveCompleted = 0,
    onObjectiveFailed = 0,
    onObjectiveVisible = 0,
    onOffboardSupp = 0,
    onPinned = 0,
    onPlaceableKill = 0,
    onPlayEnter = 0,
    onPlayDone = 0,
    onPlayFailed = 0,
    onPlayInvalid = 0,
    onPvPMissionEnd = 0,
    onRespawn = 0,
    onSpawnedReady = 0,
    onSpeechEnd = 0,
    onSuppressed = 0,
    onSuspected = 0,
    onUnsuppressed = 0,
}

以上代码定义了两个函数。onMissionStart() 函数最可能是当任务开始时由游戏调用的函数。我没有找到任何官方参考手册，但游戏似乎具有一些基于事件的脚本系统。

您提供的剩余代码可能只在加载文件时执行，因此在游戏中没有任何效果。

编辑 根据评论：

上面的代码定义了 onMissionStart() 函数。它最有可能实现了一个函数，当任务开始时由游戏调用。

如果我没有记错，您添加了以下代码：

-- OFP:isAlive(部队名称或实体集名称)
function isAlive() -- 在为该函数命名后，一个令人恼火的 "'<name>' expected near 'if'" 错误消失了，这很好。
  if OFP:isAlive("enemy1") == (false) -- 当“enemy1”死亡时，该“if...then”语句应该生成“enemy2”。
  then
    OFP:activateEntitySet("enemy2");
  end

  if OFP:isAlive("enemy2") == (false) then
    OFP:setObjectiveState("Wave2","COMPLETED")
    OFP:missionCompleted()
  end
end

这也定义了一个函数。isAlive() 函数被谁调用以及何时调用？

我在 DROPP 中找到了一个事件列表。我假设这就是您所说的任务编辑器。在某些事件上，它会运行一些函数。例如，如果所有玩家都死了，就会调用 onAllplayersDead()。
