Mapping

The TL;DR

Here is a quick rundown of the steps you need to go through to make a new map, in case you need a refresher or you're already familiar with the mapping process. Otherwise, scroll down to the tutorial.

1. When you're ingame, spawn as an observer. Open the console using \ and type mapping 10 Maps/civ/template.yml. This will open the template map, which has some presets predefined.

2. Expand the map if you need to, first select a floor tile and hold CTRL and drag it to expand. Remember to enclose the new area in indestructible walls, normally WallRockIndestructible. If you do so, remember to run fixgridatmos in the console.

3. Map to your heart's content. Don't forget to add:

   • Spawns for all factions
   • An observer spawn somewhere
   • Capturable area(s), if applicable
   • Grace walls

4. Save the map using savemap 10 mapname.yml. The file will be created in bin/Content.Server/Data. Move it to the map folder in Resources/ afterwards.

5. Create a new map metadata in Resources/Prototypes/Maps and edit it accordingly. Don't forget to define an ID, the preset and the jobs.

6. Edit the map file and add the ID you defined above to the station section.

7. Test it!!

Tutorial - Your First Map

Let’s create a simple WW2-themed King of the Hill (KotH) map called River, set in a European theater with two factions (Germans and Soviets) fighting to control a central river crossing.

Step 1: Setup and Template

Ensure the Civ14 codebase is compiled (see the note on the top of this page). Copy the template map file Resources/Maps/basic.yml.template and rename it river.yml. This template includes basic presets like weather and global lights.

Launch the game using RunAll.bat, spawn as an observer, and open the console (\). Type: mapping 10 Maps/civ/river.yml

This loads the river.yml map in the editor and spawns you as an observer, where you can edit the map.

Step 2: Expand the Map

The template map is a small grid, so let’s expand it for a KotH layout:

1. Expand the Grid: Select a floor tile (e.g., FloorPlanetGrass), hold CTRL, and drag to expand the map to a reasonable size (e.g., 100x100 tiles for a medium map). Ensure the terrain reflects a WW2 battlefield—use grass, dirt, and river tiles (FloorWaterEntity and FloorWaterDeepEntity).
2. Enclose the Area: Surround the map with indestructible walls (WallRockIndestructible, using the entity spawner) to prevent players from falling into space.
3. Fix Atmosphere: Run fixgridatmos in the console to stabilize the map’s atmosphere, ensuring no air leaks or physics issues.

Step 3: Design the Terrain

Shape the River map to fit its WW2 KotH theme:

• Central Objective: Place a capturable marker in the map’s center using MarkerKOTHOpushka. This is from the Opushka map, but it will work just fine and is already preconfigured for the German and Soviet factions, and to have a radius of 5. You can have a look at it in `Resources/Prototypes/Civ14/Entities/Markers/capturable_areas.yml.
• River: Add a winding river (FloorWaterDeep) splitting the map, with the bridge as the only crossing point. Use shallow water tiles (FloorWaterShallow) for fording. Note that water is an object, not a tile! You will need to make sure you do not accidentally double the ammount of water entities in a tile.
• Terrain Features: Scatter trees (TreeTemperate, for example), Rocks (WallRock) and bushes (found under decals) to give the map some cover and flavour.

Step 4: Add Key Elements

Include essential entities for gameplay:

• Faction Spawns:
  • Germans: Place 10 or so SpawnPointGerman in the left side of the map near the wall.
  • Soviets: Place 10 or so SpawnPointSoviet in the right side of the map.
• Observer Spawn: Add a single SpawnPointObserver in a neutral corner (e.g., map edge) or in the middle of the map for spectators.
• Grace Walls: Place temporary GraceWall entities around each faction’s base to prevent early rushes. Add GraceWallGerman around the Soviet base and GraceWallSoviet around the Soviet base. Also add GraceWall on the inside of the previous grace walls. Press Toggle BB on the sandbox menu to see its boundaries and make sure there are no holes.

Step 5: Save the Map

Save your work by typing in the console: savemap 10 river.yml

The file will save to bin/Content.Server/Data. Move it to Resources/Maps/civ/tdm/ afterward.

Step 6: Create Map Metadata

Create a new file in Resources/Prototypes/Maps/river.yml to define the map’s metadata, specifying its ID, name, path, jobs, factions, and gamemode. Based on Civ14’s structure (similar to the Camp map metadata), here’s the metadata for the River map:

- type: gameMap
  id: River
  mapName: "River (WW2)"
  mapPath: /Maps/civ/tdm/river.yml
  minPlayers: 0
  maxPlayers: 50
  maxRandomOffset: 0
  randomRotation: false
  fixedPreset: TDM
  stations:
      River:
          stationProto: StandardStationTDM
          components:
              - type: StationNameSetup
                mapNameTemplate: "River (WW2)"
              - type: StationJobs
                availableJobs:
                    # German
                    GermanCaptain: [1, 1]
                    GermanSergeant: [4, 4]
                    GermanSubmachineGunner: [10, 10]
                    GermanRifleman: [40, 40]
                    GermanMachinegunner: [5, 5]
                    GermanMedic: [3, 3]

                    # Soviet
                    SovietCaptain: [1, 1]
                    SovietSergeant: [4, 4]
                    SovietSubmachineGunner: [10, 10]
                    SovietRifleman: [40, 40]
                    SovietMachinegunner: [5, 5]
                    SovietMedic: [3, 3]

Metadata Notes:

• id and mapName: Set to River and River (WW2) for clarity.
• mapPath: Points to /Maps/civ/tdm/river.yml, or wherever your map is.
• minPlayers and maxPlayers: Set to 0 and 50 to support small-to-medium KotH matches, adjustable based on map size.
• availableJobs: Includes WW2-appropriate roles with counts similar to Opushka (e.g., 1 commander, 15 soldiers per faction). fixedPreset: Specifies KotH victory conditions (4-minute capture) of a common point.
• Checking Metadata: Ensure job IDs (e.g., SovietMachinegunner) exist in Resources/Prototypes/Civ14/Roles/Jobs/TDM/.
• Common Issues: Incorrect mapPath or undefined job IDs can prevent loading. If the map crashes, check logs in bin/Content.Server/Data/logs or validate YAML syntax.

Step 7: Update the Map File

Open river.yml in a text editor and add the map ID to the metadata and station sections, use CTRL-F to find them:

entities:
    - proto: ""
      entities:
          - uid: 1
            components:
                - type: MetaData
                  name: River (WW2)

and

- uid: 2
  components:
      - type: MetaData
        name: River (WW2)

and

- type: BecomesStation
  id: River

Ensure the id matches the metadata’s id field (River) and the name aligns with mapNameTemplate.

Step 8: Test the Map

Open Resources/ConfigPresets/Build/development.toml and change the value of map to River and the value of defaultpreset to tdm. This will make the game load the map automatically. Run the game.

Test the following:

• Spawns: Ensure Allies and Axis spawn correctly in their bases.
• Capture Point: Verify the bridge's capture point object tracks control times.
• Grace Walls: Confirm they have no holes in them.
• Terrain: Check pathfinding (e.g., no blocked routes) and atmosphere stability (no air leaks).
• Metadata: Confirm jobs load correctly and the KotH gamemode activates with the 4-minute capture condition.
• Balance: Playtest with bots or players to ensure the bridge isn’t too easy/hard to hold.Fix issues by tweaking the map in the editor or editing the metadata file, then resave.
