var wrapMode : WrapMode

Description

How should time beyond the playback range of the clip be treated?

WrapMode.Default: Read's the wrap mode from the clip (default for a clip is Once).
WrapMode.Once: Stops the animation when time reaches the end.
WrapMode.Loop: Starts at the beginning when time reaches the end.
WrapMode.PingPong: Ping Pong's back and forth between beginning and end.
WrapMode.ClampForever: Plays back the animation. When it reaches the end, it will keep sampling the last frame.

    // Make the animation loop
    animation.wrapMode = WrapMode.Loop;

using System.Collections;

    void Example() {
        animation.wrapMode = WrapMode.Loop;
