Having the camera follow a path

While Torque 3D has the camera under user control most of the time, there are times when we want the camera to follow a defined path through the scene. This can be useful during an in-game cinematic, or as part of a shooter-on-rails game. In this recipe, we will set up a path using the World Editor and have the camera follow it.

Getting ready

We will be making TorqueScript changes in a project based on the Torque 3D Full template, and try them out using the Empty Terrain level. If you haven't already, use the Torque Project Manager (Project Manager.exe) to create a new project from the Full template. It will be found under the My Projects directory.

How to do it...

In the following steps we will add a path to a level and have the camera follow it:

We will begin by adding an object to the level that we can click on. Start up the Full template-based game with the Empty Terrain level.
Press F11 to open the World Editor.
Make sure the Object Editor is active by pressing...
