Local Origin vs Abs Origin

[darkcat]

I've read the post over here:

http://developer.valvesoftware.com/wiki/GetAbsOrigin%28%29

then does Local Origin set it's parent's Abs Origin as (0,0,0)?

I've grabbed the netvar offset for local origin by "m_vecOrigin".
Everything's good but except the values in the vector are way to big if my assumption above is true.

Explanation anyone?

Look at the SDK or disassemble Those getabs... functions and see what 'calculations' if any they do. I know another forum member had to look at these functions in the process of creating his projectile weapon solvers.

For client side, GetLocalOrigin() func is nothing more than return m_vecOrigin;
and on the server project of the SDK, there's not much but Set & Get functions.
I'll search around more thou.

EDIT: Still not getting it. If anyone can help me, please leave a post. I'll be very happy. :)

because m_vecOrigin isn't always updated.

GetAbsOrigin() basically checks for a 'dirty' flag and if so, recomputes the local origin by interpolating between 2 origins it received from the server. (in C_BaseEntity these are stored in m_iv_vecOrigin).

There's another interesting concept about this. GetAbsOrigin is context sensitive (similar to pGlobals->curtime).
During CreateMove etc this value is exactly as you'd expect it.

However if you're doing things async (drawing in EndScene with multi-core rendering enabled in Source Engine games or doing it external) you might want to read the value directly from m_iv_vecOrigins. Otherwise your ESP starts skipping around :(
