Looping Motion Paths

Once a motion path is created, you can decide if you want the Object to travel on it just once, repeat the path multiple times, or travel forwards and backwards along the path. This is done by changing the Loop Type property. Explore these options to see the result. 

  1. Change the Loop Type to Loop and play the Scene.

    You see the Object travel along the path and when it gets to the end, it immediately jumps to the beginning of the path and repeats indefinitely. This doesn’t seem to be very realistic for the bird sound, but this type of loop would be useful for other situations like the sci-fi sound of a laser beam being shot repeatedly from a laser cannon.


    Something that’s very important to notice is that the motion of the Object continues, even though the lower timeline shows only the initial motion points. It’s normal behavior in the timeline that repeated elements are not visually presented in the timeline.

    Perhaps you want a sound to travel back and forth along a motion path, like a pacing tiger or robot sentry.

  2. Change the Loop Type to Ping Pong and play the Scene.

    You see the bird fly to the end of the path and do an immediate 180 degree turn and travel back to where it came from and so forth.

    This is again, not a very natural way for a bird to fly. It would be much more natural for the bird to fly in more of a circular path. To do this, you can add another motion point at the end of the path that is aligned with the first point.

  3. Add a Motion Point after the Motion Point positioned at  and move it to the same position as the first Motion Point (the origin, 0,0,0).

    Now you can visually see the loop of the bird's flight. To have the effect you want, you’ll need to set the Loop Type back to Loop.

  4. Change Loop Type to Loop and play the Scene.

    Now the bird is flying circles around the Scene!
