Ever wanted to link certain region ID’s to have certain effects applied when you encounter a battle on them? Now you can! This Tips & Tricks will show you just how to do that!

You can grab the copy/paste code here: 

Insert the following code into your map effect. Change the values in red to fit the settings of your game.

<Custom Passive Condition>
// Set the initial condition setting to true.
var condition = true;
// Check if it is a battle playtest...
if (BattleManager.isBattleTest()) {
  // ...set it to false.
  condition = false;
// Check if a map exists and the party is in battle.
} else if ($gameMap && $gameParty.inBattle()) {
  // Make a list of the active maps to automatically enable the effect.
  var activeMaps = [];
  // Insert the ID's of the maps you want this state to be active on.
  activeMaps.push(123, 124, 125, 126, 75);
  activeMaps.push(127, 128, 129, 130); 
  // Make a list of the terrain tags to automatically enable the effect.
  var terrainTags = [];
  // Insert the terrain tags you want this state to be active on.
  terrainTags.push(0, 1, 2, 3);
  // Make a list of the region ID's to enable the effect.
  var regionIds = [];
  // Insert the region ID's you want this state to be active on.
  regionIds.push(10, 11, 12, 13);
  regionIds.push(14, 15, 16, 17);
  // Check if the list of active maps has any items.
  if (activeMaps.length > 0) {
    // Check if the active maps do not contain the current map.
    if (!activeMaps.contains($gameMap.mapId())) {
      // If it doesn't, disable the effect.
      condition = false;
    }
  }
  // Check if the list of terrain tags has any items.
  if (terrainTags.length > 0) {
    // Check if the terrain tags do not contain the current terrain tag.
    if (!terrainTags.contains($gamePlayer.terrainTag())) {
      // If it doesn't, disable the effect.
      condition = false;
    }
  }
  // Check if the list of region ID's has any items.
  if (regionIds.length > 0) {
    // Check if the region ID's do not contain the current region ID.
    if (!regionIds.contains($gamePlayer.regionId())) {
      // If it doesn't, disable the effect.
      condition = false;
    }
  }
// If the player isn't in battle...
} else {
  // ...then disable the effect.
  condition = false;
}
</Custom Passive Condition>
