Using Progress on a Bezier Curve

Warning: Please note

I have a problem tweening and using progress on a bezier curve

 

See the Pen pxdgF by DuncanBudapest (@DuncanBudapest) on CodePen

 

I hope the codepen makes the situation clear.

 

In the code the object 'steps' around the curve. As I understand progress represents the complete tween so any position can be represented by 0 to 1. In my example my total progress is 0.5 but the object tweens to 75% of the track.

 

In the complete code there are multiple objects and there is some degree of control using the timeline. I've stripped the code down to make it easier to understand.

Hi and welcome to the GreenSock forums.

 

Thanks for the CodePen demo.

 

You need to add ease:Linear.easeNone to your config object:

 

var config = {bezier:{type:"cubic",curviness:1, values:track_1, autoRotate:true},  paused: true, ease:Linear.easeNone};
