Letter Launcher

Letter altitude: determines the distance where the letter will come from. It admits negative values. The demo uses 10.
Letter rotation: determines the initial rotation applied to each letter. It admits negative values. The demo uses 10.
Duration
Stagger: the delay to apply between lines, words or chars. This means, when the first char starts animating, the second will fire after “x” seconds determined by the stagger and so on.

Letter Launcher animation uses ScrollTrigger Library to fire on scroll. Learn more about ScrollTrigger here.
Trigger: the element that will fire the animation on scroll. Use the keyword “this” to use the element itself as the trigger.
Start: determines the position of the Trigger to fire the animation. “top bottom” means when the top of the element hits the bottom of the viewport.
End: determines the end of the animation if needed. It is specially useful when using the Scrub property.
Delay
Scrub: to attach the animation to the scroll so that it plays when scrolling.
toggleActions: Determines how the linked animation is controlled at the 4 distinct toggle places – onEnter, onLeave, onEnterBack, onLeaveBack, in that order. “play pause resume reset” will play the animation when entering, pause it when leaving, resume it when entering again backwards, and reset (rewind back to the beginning) when scrolling all the way back past the beginning.

In case you need to fire the animation on additional events.
Trigger on: click or hover.
Element: the element that will fire the animation on the additional event selected.
