I have a view attachment attached to a hand anchor. When the attachment is facing away I don't want it to render.
I might be missing something obvious, but I've made a System that runs on every render loop. In the update call I'm getting a reference to the Attachment using components.
And this is as long as I got. I can't figure out how to get the normal of an Entity I receive in the update function.
My plan was to take the head anchor normal and compare it to the entity normal. If they are facing each other I render the viewAttachment, otherwise not.
Is there a simpler way? And if not, how do I get the normal of an entity?
