Thanks for the quick reply.
In my use case I have a side element that fades in as the draggable element gets closer to the target or basically as the hitTest gets closer to 100%.
Right now I solved it with a REALLY UGLY if statement.
NOT my proudest moment, it's crunch time. REALLY thanks of the reply. Love the draggable plugin. SAVED MY BACON.
if(this.hitTest("#hit-test", "90%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.1});
}else if(this.hitTest("#hit-test", "80%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.2});
}else if (this.hitTest("#hit-test", "70%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.3});
}else if (this.hitTest("#hit-test", "60%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.4});
}else if (this.hitTest("#hit-test", "50%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.5});
}else if (this.hitTest("#hit-test", "40%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.6});
}else if (this.hitTest("#hit-test", "30%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.7});
}else if (this.hitTest("#hit-test", "20%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.8});
}else if (this.hitTest("#hit-test", "10%")) {
TweenMax.to("#photo--missing", tt, {autoAlpha:.9});
}else{
TweenMax.to("#photo--missing", tt, {autoAlpha:1});
}
