DP md3 tag origin question

[silverjoel]

It seems in DP(maybe other engines) that the setattchment function gives the entity an origin of '0 0 0'. So, as the owning model's origin moves, the attachment's origin still stays at '0 0 0'. Does anyone know a way to get the actual origin of the model attached? Or better yet, a tag on the model that is attached?

//DP_QC_GETTAGINFO
//idea: VorteX, LordHavoc
//DarkPlaces implementation: VorteX
//builtin definitions:
float(entity ent, string tagname) gettagindex = #451;
vector(entity ent, float tagindex) gettaginfo = #452;
//description:
//gettagindex returns the number of a tag on an entity, this number is the same as set by setattachment (in the .tag_index field), allowing the qc to save a little cpu time by keeping the number around if it wishes (this could already be done by calling setattachment and saving off the tag_index).
//gettaginfo returns the origin of the tag in worldspace and sets v_forward, v_right, and v_up to the current orientation of the tag in worldspace, this automatically resolves all dependencies (attachments, including viewmodelforclient), this means you could fire a shot from a tag on a gun entity attached to the view for example.

Thanks, I just found that myself. It can be a pain to read through all of dpextensions.qc.
