Question about JumpStart

[pixeldroid]

Quick question about the TimelineMax Jump Start at:

See the Pen ryfJu by GreenSock (@GreenSock) on CodePen.

What is the purpose of "textEffect" in

tl.staggerFrom(txt, 0.4, {alpha:0}, 0.06, "textEffect");

I don't understand the use of a string as the final param in this function call.

Thanks.

The final param is the position parameter which controls at which time the animation will be inserted.

 

What is happening there is that it is inserting that animation at a label of "textEffect" so that the next animation can be placed at the exact same time.

 

note both animations use "textEffect" as the position parameter. 

tl.staggerFrom(txt, 0.4, {alpha:0}, 0.06, "textEffect");
tl.staggerFrom(txt, 0.8, {rotationY:"-270deg", top:80, transformOrigin: "50% 50% -80", ease:Back.easeOut}, 0.06, "textEffect");

 

Definitely check out this comprehensive overview of the Position Parameter.

Thanks Carl!

To clarify, in the codePen example, you don't use "add" to insert the label.  This suggests that a label is declared upon first useage.  Is that correct?

Thanks.

yup, that's it.
