How do I use the PlayAnim function in SpriteManager 2?

I am using Sprite manager 2 and I have managed to make it the sprites playing the default animation. Now, I wanna make my character play the Jump animation or walk animation by calling the PlayAnim function from a Java script attached to the character. Sorry, I am new to this & I am c# illiterate :(

SM2 comes with a set of documentation to help you get started take a look in the SM2 Docs folder, and open up index.html.

Here's some example code from the documentation, which assumes you've set up a PackedSprite object called sprite:

// Play "walk" animation:
sprite.PlayAnim("walk");

// Play "walk" animation if it isn't playing already:
sprite.DoAnim("walk");

// Play the animation at index 3:
sprite.PlayAnim(3);

// Play the animation referenced in the variable walkAnim:
sprite.DoAnim(walkAnim);
