Rotating object to match Physics2D angle

[Michael71 59 Likes (Contributor)]

Hello,

 

I would be interested to know if there is a way to dynamically know the rotation that is applied with Physics2D accelerationAngle, or angle in order to rotate the object and seem like its pointing along the animation path.

 

e.x if we have a rocket and we want it to be pointed towards the end of the animation point each each (second/frame) 

 

I have set an example here: 

See the Pen nfdBJ by netgfx (@netgfx) on CodePen

 

What I want to achieve is to be able to rotate the rocket depending on the angle of the animation path.

 

Thanks in advance.

I think you'd need to use an onUpdate and track the previous and current x/y or top/left and then adjust the rotation accordingly with Math.atan2(). Not exactly simple, but doable.

Ok I got that, but how can I reset the rotation angle on each update? Or do I have to set a new tween each time?

You can use a TweenLite.set() like:

TweenLite.set(element, {rotation:YOUR_ROTATION});
