Jump to: navigation, search


  • World is a static class used to access various aspects of the Trainz environment.


Contents

Constants

  • These constants are used to define various values and can be used as mnenomics.
  • If accessed from scripts the values must be prefixed World., for example: 
World.SetWeather(World.WEATHER_TYPE_LIGHT_SNOW,World.WEATHER_CHANGEABILITY_PERIODIC);


Camera View Modes

  • These values can be used either to choose the current camera viewing mode through World.SetCameraMode(), or to restrict certain camera modes from being accessed through methods such as World.SetCamera().
public define int CAMERA_INTERNAL = 1 Internal cabin camera view.
public define int CAMERA_EXTERNAL = 2 External train camera view
public define int CAMERA_TRACKING = 4 External tracking camera view.
public define int CAMERA_ROAMING = 128 Roaming camera view.


Camera Flags

  • These flags are used in addition to the Camera Mode Flags to allow or disallow specific camera actions.
public define int CAMERA_SWITCH_VIEWS = 8 User permitted to swap between the camera views.
public define int CAMERA_SWITCH_VEHICLES = 16 User permitted to swap vehicles within the current train.
public define int CAMERA_SWITCH_TRAINS = 32 User permitted to swap to other trains which are in the consist menu.
public define int CAMERA_LOCKED = 64 User is NOT permitted to adjust camera (i.e. zoom, pan etc.).

   Sleep(World.PlaySound(soundAsset,"sounds/allaboard.wav",1000.0,10.0,100.0,Station,"a.loudspeaker");
Notes
  • Plays a .wav sound file from the given asset's folder.
  • If the sound is to be directional a mono sound file is required.
  • This method does not return after the sound has finished playing: it returns as soon as it is called.
  • This means your code will keep on executing while Trainz is playing the sound.
  • If you want to wait for the sound to complete playing before moving on, wrap the PlaySound() call up in a Sleep() call. Note! This works only in Trainz versions before TS12. For newer versions, TS12 and TANE, you can hard-code the duration of the sound, or store it in the extensions container of the config.txt file.
  • The sound volume will be at a maximum for a camera position at or less than the value of the near parameter and will reduce with distance until the hearing position reaches far, when the sound will be inaudible.

SetCamera

public native bool SetCamera(MapObject focus)
public native void SetCamera(Junction focus)
public native void SetCamera(Vehicle focus, int cameraMode)
public native void SetCamera(Train focus, int cameraMode)
Parameters
  • focus = Object on which the camera is to be focused.
  • cameraMode' = One of the Camera View Mode constants defining the view which should be assigned to the camera.
Returned Value
  • The first variant returns a boolean to indicate success or failure.
  • Remaining variants do not return a value
Syntax 
World.SetCamera(train.GetVehicles[0],World.CAMERA_TRACKING); // sets the camera to track the first vehicle in the train.
Notes
  • Junction alias removed in TRS19?


SetCameraAngle

public void SetCameraAngle(float yaw, float pitch, float radius)
public obsolete void SetCameraAngle(int yaw, int pitch, float radius)
Parameters
  • yaw = Camera rotation in radians (float) or degrees (int), 90 is a direct front view.
  • pitch = Camera angle relative to the horizon in radians (float), or degrees (int), 0 is horizontal, 90 points vertically upwards.
  • radius = Distance in metres to the object in focus.
Returned Value
  • None
Syntax 
World.SetCameraAngle(90,0,25); // Sets the camera to a direct frontal view at 25 metres from the currently focused object.
Notes
  • Radius is measured from the object origin point (0,0,0). If there's no target object this will be the distance to the ground.
  • Note difference in units of yaw and pitch depending in the method signature used.
  • The integer version of this method call is obsolete in TRS19.


SetCameraFlags

public native void SetCameraFlags(int flags)
Parameter
  • flags integer value defining what the user is permitted to do with the game camera.
Returned Value
  • None
Syntax 
// User is permitted to select External or Tracking views only.
   World.SetCameraFlags(World.CAMERA_EXTERNAL | World.CAMERA_TRACKING);
Notes


SetCameraMode

public void SetCameraMode(int mode)
Parameter
  • mode = Camera mode to select.
Returned Value
  • None
Syntax 
World.SetCameraMode(World.CAMERA_TRACKING);
Notes


SetEditingCamera

public void SetEditingCamera(GameObject actor, bool bIsActorEditingCamera)
Parameter
  • actor = The script who is intended to edit the camera position.
  • bIsActorEditingCamera = True to begin editing, or False to end the editing operation.
Returned Value
  • None
Syntax 
World.SetEditingCamera(myScript, true);
Notes
  • Hints to the caching systems that the camera position is in the process of being changed. This may reduce the amount of streaming that will occur until the change is complete.
  • This is intended for use-cases where the decision to move the camera happens in advance of the actual call to SetCamera() or etc., for example when the new camera target needs to be streamed in first.
  • There is no advantage in calling this unless your code then sleeps/waits before undoing the call.
  • It is not required to call this before using SetCamera() etc.
  • A boolean state is stored per actor; multiple calls to enable editing on a single actor do not need to be matched to multiple calls to disable editing.
  • It is counterproductive to call this when transitioning the camera over a short distance (ie. where the source and target locations can see each other). If jumping to a new location, followed by a visual camera transition at the new location, camera editing may be enabled around the target-selection for the jump, and the jump itself, but should be disabled before proceeding with the transition.

  • 0.0 = midday
  • 0.25 = 6 p.m.
  • 0.5 = midnight
  • 0.75 = 6 a.m.

SetSceneryDrawDistance

public obsolete native void SetSceneryDrawDistance(float distance)
Parameters
  • distance = unused.
Returned Value

SetTargetObserver

public void SetTargetObserver(GameObject observer)
Parameters
  • observer = The game object to receive targeting messages.
Returned Value
  • None
Syntax 
SetTargetObserver(self);
Notes
  • It is unlikely a script programmer would ever need to use this method.
  • Causes the specified object to receive "Track", "LeftClick" messages when a track is clicked. Causes the specified object to receive "Interface-Event", "Left-Click" messages when a targetable MapObject is clicked. May cause the functionality of a left mouse click to change from what the user is expecting, so should be used with caution. Used in modal scripts to allow the user to indicate a location for train placement, etc. As there is only a single observer at any given time, the script must take care to only call this function when entering placement mode at the user's request.


SetWeather

public native void SetWeather(int type, int changeability)
Parameters
Returned Value
  • None
Syntax 
World.SetWeather(World.WEATHER_TYPE_HEAVY_SNOW,World.WEATHER_CHANGEABILITY_EXTREME); // April in Paris.

Returned Value
  • Whether the change was completely successful
Syntax 
World.SetWorldEditModeEnabled(World.PERMIT_EDIT_TRAINS | World.PERMIT_EDIT_CONSISTS, True); // Enable player editing of trains and consists
Notes
  • This does not affect scripts which may alter the world, only the availability of the player world editing tools (i.e, the Surveyor tabs).
  • Added in TRS19?


SynchronouslyLoadGameObjectByID
