Got some updates on this.
I was able to solve my problem of not being able to configure the particle
system when dispatched from the server like this:
1. Created a temporary entity on Server and Client (CSynaesthesiaEntity
and C_SynaesthesiaEntity).
- On the server, it just transmits some info of the sound to the
client version (some EmitSount_t members).
- On the client, it spawns a client-side only entity
(C_SynaesthesiaProcessor) to configure, dispatch and control a particle
effect.
2. Created a client-side only entity (C_SynaesthesiaProcessor) that
creates and maintains the particle effect based on information from the
sound metadata and audio features extraction.
I'm almost sure that that's not the most efficient way to do it, but I
believe the performance loss won't be a problem for a prototype.
Now, the next task is to use an audio feature extraction library to read
some information from the game sounds. I have already integrated the
library (http://marsyas.info) to the source code using the FMOD tutorial on
the wiki as guide.
However, as I am using the sounds from HL2 (my sounds folder does not exist)
* I still haven't figured out how to access the game sound files - that are
inside the GCF*. A really simple but ugly approach is to extract the game
sounds from the GCF to the mod's sound folder, but I would like to avoid
that. Can someone shed some light on this matter?
Thanks!!
