Update attachments at the ending of the addToScene function for parents. And with this... *drum roll* Client-side attachments are at last functional and stick visibly. Fix the last segmentation fault (apparently). So far attachments seem to be fully functional, although removing the parent causes children to go to origin 0,0,0 and possibly still cause such a fault (though this should already be addressed) Fix a bug in falling code where entities get stuck Also check if the parent has been removed server-side, and detach the child if so. Fixes children going to origin 0,0,0 when their parent is removed. Unset all attachment properties when permanently detaching (on both the client and server). Also store less data we don't need Create a separate function for detaching, and also update lua api documentation When a child is detached, update its position from the server to clients. This WILL cause it to get positioned slightly differently client side, as the server attachment system only copies parent origin and knows not about mesh / bone transformation. This prevents different clients seeing the object detached in different spots which is most correct Update the position of attached players to clients. An attached player will see himself move, but this is currently VERY ugly and laggy as it is done by the server (it probably must stay this way too) Use a different approach for locally attached players. This allows for smooth positio transitions to work, as well at the player turning around freely. Still buggy however
