[1.1.5] Sprite vs Group collision

[psychotron]

Hi folks,

 

I'm new to Phaser, seems like a nice framework so I decided to try it for recent Flappy Jam.

 

However I cannot wrap my head around sprite vs group collision.

 

I'm creating a rotated group (let's say 45 degrees) which consist of 2 sprites (lower/higher pipe parts).

But that rotation of group cause player to collide directly with AABB bounding boxes generated around rotated sprites.

 

How can I achieve desired collision directly on sprite within group? How can I switch from AABB to SAT based collisions?

 

Please see attached image for better description of a problem.
