In Haxe/Flambe, how do I go about rotating or scaling an Entity, so that its children are rotated at scaled proportionally

I'm basically trying to emulate what you see in many other frameworks like Flash, XNA, etc. If I create a hierarchy of nested entities on stage, how do I rotate, scale, or translate a parent entity and have its children rotate, scale, and translate relative to the parent's origin point?

Lets say you have this setup:

Entity (called enemy)  
> Sprite  
 -- Entity (called leg)  
  > ImageSprite  
 -- Entity (called arm)  
  > ImageSprite
 -- Entity
  > ImageSprite

If you want to rotate the enemy, you should do enemy.get(Sprite).rotation._ = 35; Then the whole character should rotate.

If you want to rotate a part of it, use leg.get(Sprite).rotation.animateTo(35, 0.5, Ease.sineOut);

You can nest entities using addChild, and components (like Sprite) using add(). The displaylist is build using entities that contain Sprites, but not plain nested Sprites like Flash.

I suggest you could take a look at my Flambe guide, some basic concepts (that can be confusing at start) are explained in it https://github.com/markknol/flambe-guide/wiki/

Have fun, please let know if you have questions.
