STW Mobile Spawn

Turn a Game Master-placed vehicle into a friendly, moving spawn point. When the vehicle stops, it becomes a useful rally point; when it moves, the spawn quietly gets out of the way.

A player, Game Master and server-owner guide by STW (ScienceTechWorks).

What it adds

STW Mobile Spawn links one mobile spawn to one vehicle. The server owns the link, watches the vehicle, and creates the player spawn point and map marker only when the vehicle has come to rest.

Think of it as a mobile rally point. Park the vehicle, let the system settle for a moment, and your faction gets a spawn. Drive away and the spawn is removed until the vehicle stops again.

For Game Masters: create a mobile spawn

  1. Place a supported vehicle in the world and make sure it is a vehicle with a usable vehicle controller.
  2. Select the vehicle and open the Game Master context menu.
  3. Choose Assign as Mobile Spawn.
  4. If you want to place the editable representation directly, search the Entity Browser for STW Mobile Spawn and place the mobile-spawn proxy close to the vehicle.
  5. Stop the vehicle and wait for the stop debounce to finish. The faction spawn point and map marker will appear at the vehicle's origin.

The proxy is the Game Master-facing object. It follows the vehicle and can be selected for properties and removal; the player-facing spawn point is managed by the server.

One vehicle, one spawn. Assigning an already-assigned vehicle does nothing. Removing the assignment, deleting the proxy, or destroying the vehicle removes the associated spawn point and marker.

For players: using a mobile spawn

When a friendly assigned vehicle is stopped, its marker appears on your map and its spawn point becomes available. Spawn normally through the game's spawn interface.

If the marker is missing, the vehicle may still be moving, waiting for its stop timer, assigned to another faction, or no longer valid. A vehicle that is moving is never a usable spawn, even if an old client view briefly shows a marker.

Faction visibility

Mobile spawns are private to their friendly faction. The faction is normally inherited from the vehicle or its driver. If no faction can be resolved, the server uses US as the default.

How the vehicle state works

Vehicle stateWhat you seeWhat players can do
MovingMobile spawn point and marker are removed or hidden.No one can use this vehicle as a spawn.
Stopped brieflyThe server waits for the configured stop debounce.Keep waiting; the spawn is not ready yet.
StoppedA faction spawn point and tinted map marker appear at the vehicle.Friendly players can spawn there.
Destroyed, replaced or unassignedThe proxy, spawn point and marker are cleaned up.The old spawn cannot be used.

The default movement threshold is 0.05 m/s, with a 2-second debounce. This avoids flickering while a vehicle settles or rocks slightly.

Server configuration

On first start, the server creates:

$profile:/STW/MobileSpawn/STWMobileSpawnConfig.json

Stop the server before editing the file, keep a backup, and restart after making changes. The most useful settings are:

SettingWhat it controlsDefault
EnabledMaster switch for the service.true
PersistenceEnabledSaves assigned vehicles and restores them after restart.true
EnableRuntimeSpawnPointCreates the native player spawn point when a vehicle is stopped.true
MovementSpeedThresholdMaximum speed still considered stopped, in metres per second.0.05
StopDebounceSecondsHow long the vehicle must remain below the threshold before becoming active.2.0
WatchIntervalMillisecondsHow often assigned vehicles are checked.1000
DefaultFactionKeyFallback faction when the vehicle has no faction.US
Persistence details: records are stored in $profile:/STW/Persistence/STWMobileSpawn.json. The vehicle prefab, world transform and resolved faction are saved. Inventory, damage, fuel, crew and attached entities are not saved.
