Switcher

Switcher is an object that disables or enables its child nodes at a specified distance from the camera. Possible use cases are:

  • Enabling one object and disabling another at a specified distance
  • Disabling an object while moving away
  • Enabling an object while approaching

Each object is composed of Switcher and two spheres of different colors

Adding a Switcher#

To add Switcher to the scene via UnigineEditor, do the following:

  1. Run the project with UnigineEditor.
  2. On the Menu bar, click Create -> Optimization -> Switcher.

  3. Place the node somewhere in the world.
  4. Make the node that will be controlled by Switcher a child of the latter.
  5. Specify the enabling and the disabling distance in the Switcher parameters.

Switching between Two Objects#

To switch between two object at the specified distance (like shown in the picture above), do the following:

  1. Create a Node Dummy for convenient grouping.
  2. Make the first Switcher the child of the Node Dummy.
  3. Make the first object the child of the first Switcher and specify its maximum visibility distance.
  4. Make the second Switcher the child of the Node Dummy.
  5. Make the second object the child of the second Switcher and specify its minimum visibility distance.

Notice
To make objects switch at the same point, the maximum visibility distance of the first one and minimum visibility distance of the second one should match.

Switcher Parameters#

In the Node tab of the Parameters window, you can adjust the following parameters of Switcher:

Node tab of the WorldSwitcher node
Min Distance The minimum distance of visibility, in units. If the camera is closer to a node than this minimum distance, the node is not visible.
Max distance The maximum distance of visibility, in units. If the camera is further from a node than this maximum distance, the node is not visible.
