minetest/src/content_cao.cpp
MirceaKitsune 948b5a8be7 Complete the attachment framework.
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.

// be attached to its parent. If a bone is set we attach it to that skeletal
// bone, otherwise just to the object's origin. Attachments should not copy parent
// position as that's laggy... instead the Irrlicht function(s) to attach should
// be used. If the parent object is NULL that means this object should be detached.
// This function is only called whenever a GENERIC_CMD_SET_ATTACHMENT message is received.
// We already attach our entity on the server too (copy position). Reason we attach
// to the client as well is first of all lag. The server sends the position
// of the child separately than that of the parent, so even on localhost
// you'd see the child lagging behind. Models are also client-side, so this is
// needed to read bone data and attach to joints.
// Functions:
// - m_attachment_parent is ClientActiveObject* for the parent entity.
// - m_attachment_bone is std::string of the bone, "" means none.
// - m_attachment_position is v3f and represents the position offset of the attachment.
// - m_attachment_rotation is v3f and represents the rotation offset of the attachment.
// Implementation information:
// From what I know, we need to get the AnimatedMeshSceneNode of m_attachment_parent then
// use parent_node->addChild(m_animated_meshnode) for position attachment. For skeletal
// attachment I don't know yet. Same must be used to detach when a NULL parent is received.
