TimeSensor VRML97 Helper

The TimeSensor helper lets you add time-based animation controls, such as the start and end frames for a particular object's animation, and looping. Use this helper to split up an object's animation keys over several triggers, to automatically start an animation upon loading the .wrl file, or to make animation endlessly loop.

Procedures

To assign an object to a TimeSensor helper:

  1. Add a Time Sensor object by clicking the Time Sensor button and then click-dragging in the Top viewport to create its icon.
  2. Press Pick Objects and select the (animated) geometry to control.
  3. Use the controls to adjust the start and end times of the animation, and to loop the animation.

Interface

The Time Sensor rollout contains the following options:

Loop

Repeats the animation from the start-time frame to the stop-time frame.

Start on World Load

Starts the animation so that it will be running when the file is loaded into the browser.

Note: This option is only available when Loop is turned on. Otherwise, the animation will start and stop at the specified times.
Start Time/Stop Time

Specifies the range of frames to play.

Note: If the start time is after the end time, the animation will play from the earliest frame to the last frame. It will not play the animation backward.
Pick Objects

Lets you select the objects to control with this TimeSensor.

Delete

Deletes an object from the list of picked objects.

Icon Size

Adjusts the size of the helper object in the viewports.
