Working With...Area Zones

Area zones are containers for area scenery and area events that can be shared across rooms in the zone. For instance, you might create a desert zone with sandy wastes and dry air, or a dungeon zone with crumbling stone walls. 

MyGame.createAsset({
    class: "Room",
    name: "Southern Dunes",
    zone: "Desert Zone"
  });  
    
  MyGame.createAsset({
    class: "Zone",
    name: "Desert Zone",

    area_scenery: {
      air: { enabled: true, description: "The air is searingly dry. " },
      sky: {
        enabled: true,
        description: "Even the sky is burnt to a pale sandy color. ",
      },
      sun: {
        enabled: true,
        description: "The sun burns in the sky. ",
      },
      floor: { enabled: true, description: "Nothing but endless sand. " },
      sound: { enabled: true, description: "A constant dry whisper of shifting sands. " },
    },

    area_events: {
      frequency: 0.1,
      randomize: true,
      array: [
        "Sands shift beneath your feet. ",
        "A brief dry breeze does nothing to cool you. ",
        "Heat haze shimmers over distant dunes. ",
      ],
    },
  });

String Array Function

Zone descriptions are subject to String Array Function which means that they can be set to return dynamic results. For instance, if you had a day/night cycle, you might set certain phenomena to appear differently during day and night. 

MyGame.createAsset({
    class: "Zone",
    name: "Desert Zone",

    area_scenery: {
      sun: {
        enabled: true,
        description: function () {
          if( MyGame.getVar(is_night) ) { // using a world variable
            return `The sun lies somewhere below the horizon. `;
          }
          else {
            return `The sun bakes the desert floor. `;
          }
        },
      },
      moon: { 
        enabled: true, 
        description: function () {
          if( MyGame.getVar(is_night) ) {
            return `A big red desert moon illuminates the sands. `;
          }
          else {
            return `The moon is hidden beyond the horizon. `;
          }
        },
      },
      stars: {
        enabled: true,
        description: function () {
          if( MyGame.getVar(is_night) ) {
            return `Stars in their millions dot the coal blue night sky. `;
          }
          else {
            return `The stars are hidden by the blazing sun. `;
          }
        },
      },
    },
