The Object Manager Extension example demonstrates the following:

• How to install a new object manager

This example shows how to subclass and install your own version of the DtVrfObjectManager to extend its functionality.

How to Run the Example

This example demonstrates how to install your own derived object manager.

Usage

In the Launcher, click the Plug-ins button to bring up the Plug-ins Selection dialog. Enable the plugin. Then launch VR-Forces.

The vrfSim console will immediately begin repeatedly displaying 'MyObjectManager::tick()'. This confirms that the derived object manager is in use.
