Ok next question, tried to find the answer to this but couldn't find it. But I'm looking for a way to clean up this bit of code:
var bScene1 = new TimelineMax()
bScene1
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=2')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
.set('#flex-head', {backgroundPositionY:'-=210px'}, '+=0.05')
...
and this goes on for another 80 something times. Surely there is a more effecient way to write this.
