Transform Path

A world transform path is a succession of transformations based on an arbitrary path. The objects that are made children of the WorldTransformPath can move along with these transformations.

Adding Transform Path

To add a transform path to the scene via UnigineEditor, do the following:

  1. Run the project with UnigineEditor.
  2. On the Menu bar, click Create -> World -> Transform Path.

  3. Choose the path to the .path file.
    Notice
    The path can be changed afterwards in the World Transform Path tab -> Path field.
  4. Place the object somewhere in the world.

Adding Objects Moving along the Pass

To make objects move along the pass, do the following:

  1. Make the object the child of the path.
  2. Set the same initial positions of the object and of the path.
    Notice
    If the object has coordinates different from the path, it will have the corresponding offset relatively to the path.
  3. To put the object in motion, click Play in theTransform tab of the WorldTransformPath.
  4. Adjust the playback parameters.

Parameters

In the World Transform Path tab of the Parameters window you can adjust the following parameters of the transformation path:

Path Sets a path to the new .path file.
Orientation Indicates whether the object should be oriented along the path or keep its initial position.

Playback Parameters

The WorldTransformPath has the following playback parameters:

Loop Loops the transformation defined by the path.
Orientation Indicates whether the object should be oriented along the path or keep its initial position.
Radius Sets the radius for the WorldTransformPath applying (valid only outside the viewing frustum). If the child object transformed according to the path gets outside the viewing frustum, but stays in the radius range, the playback of the transformation sequence does not stop.
Time Sets the time, from which the playback of the transformation defined by the path starts.
Notice
If the object is oriented along the path, its transformation will correspond to the path transformation at the specified time. Otherwise, only position of the object will be changed.
Speed Sets the speed of playback of the transformation defined by the path.
Notice
Negative values provide the reverse playback.
Play Continues playback of the transformation defined by the path, if it is paused, or starts the playback, if it is stopped.
Speed Stops the playback of the transformation defined by the path. This function saves the playback position so that playing of the transformation defined by the path can be resumed from the same point.
