Change Speed (vuo.time.changeSpeed)

Makes time run faster, slower, or backwards.

This node is useful for dynamically changing how fast an animation happens. Unlike using the Multiply node (which will cause time to jump if you change the speed multiplier), this node ensures time is continuous when changing the speed.

• Time — A time, such as the output from the Refreshed at Time port of a Fire on Display Refresh node. Each time value should be greater than the previous one.
• Speed — How fast time should move. Speed 1 means the output time will move at the same speed as the input time. Speed 2 is twice as fast. Speed 0 is stopped. Speed -1 is backwards at the same speed as the input time.
• Reset — When this port receives an event, the node resets its time to 0 and continues running.

Thanks to vjsatoshi for developing the node this is based on.

Example composition:

• Change Speed with Mouse: Changes the speed and direction of a checkerboard sliding across the window as the mouse is moved left or right.
