checkSrcEveryFrame and updateWorldTransform

[bizzell]

Hi. Not so much of an issue but more of a question...

At the URL below: https://github.com/blairmacintyre/aframe-look-at-billboard-component

the following attribute values are listed: checkSrcEveryFrame and updateWorldTransform. I notice they are no longer listed as look-at component attributes here. Are they no longer valid?

I'm using a combination of Look-At, Orbit Controls and Check Points components to create an interface that allows the camera to be animated towards a entity when a user interacts with it. I'd like the object to be 'square on' to the camera 'lens' when the camera stops in front of it. But this rarely seem to be the case. I was hoping to try out out these attributes in case they might help solve this problem.

Prior to using Look-At I've tried getting the position and rotation of the camera in order to have an entity mirror the camera's rotation. But this seems problematic, due to the entity's position being calculated relative to a parent entity having being rotated using Orbit-Controls?

checkSrcEveryFrame and updateWorldTransform, sound like they may be useful for solving this problem?

Any advice or thoughts would be welcome. Thanks.
