Therefore, the lua script no longer needs to run every X seconds either, just once per entity. Finish fixing the material color code. But it won't work until MineTest has dynamic lighting... another day another feature. Extra checks for the bone positioning / rotation code Many checks and consistency improvements to the client attachment code Make a separate function for checking if a client object is attached. A more in-depth change will be needed here to fix reading of invalid pointers Use a different method of fetching the parent. Fixes the mass segmentation faults when rendering an attachment (some still happen though) Major change to how attachments are handled. Fix the last segmentaton fault, which was due to the parent becoming invalid while being refreshed / removed which would bause the child to remain attached to nothing. Parents remove their children when being deleted themselves and add them back when re-added. Attachments are stored inside a 2D a vector which easily allows both a child to find their parent and a parent to find its children. Remove attachment list entry when an object is being permanently removed. Also avoid duplicate entries in this list when re-attaching the same object The "big code comments" can now go away. Client attachments almost work properly, and I know what else needs to be done
*	Complete the attachment framework.	MirceaKitsune	2012-11-25
\| \| \| \| \| \| \| \| \| \| \| \|	The child ID can now be checked against the parent ID in content_cao.cpp so the parent can be detected. Actual attachment code to come Divide attachment system between server attachments and client attachments, neither coded right now. As explained in the code comment: // Attachments need to be handled on both the server and client. // If we attach only on the server, models (which are client-side) // can't be read so we don't know the origin and orientation of bones. // If we attach only on the client, the real position of attachments is // not updated and you can't click them for example.

Due to the current lighting systems it doesn't work yet, but the full implementation is there Framework for the attachment system, with no actual functionality yet Send bone and player object to the setAttachment function in content_sao.cpp, but we need a way to translate it there and send it to the client I will also want position and rotation offsets to be possible to apply to attachments Network object ID from server to client. This will be used to identify the parent client-side and know what to attach to
