Quake 2 model origins

[Neoptolemus]

Hi everyone,

I've been working on a new Quake 2 bot quite successfully so far, he's running around maps happily and even strafes around corners and looks ahead in the path like a human does.

However, I'm having a bit of trouble getting him to pick up certain items. It looks as though there's something a bit screwy with the origin point of certain entities. For example, if I ask him to run to the origin of the rocket launcher in Q2DM1 that overlooks the outdoors area, he instead runs to the super shotgun just by the open arena section. However, if I stand by the rocket launcher and tell him to run to my origin, he'll run up there with no problem at all. I've also noticed that when given free reign, he only chooses to run to a small selection of items, and I can't help but wonder if its because the other items have odd origins that he can't find a path to.

Has anyone come across a similar issue in Half-life where an entity's origin may be elsewhere from its actual location? Or is it more likely that it's a bug in the bot code that interprets this data?
