Why would you use pressure waves as packet emitters? It'd be far, far more reasonable (and easier) to use sound. Source already has the capability to have sound refract off of buildings, be blocked, etc. You'd just need to modify it. It'd work much better - especially since wireless communication *is* sound - in the 2.4ghz spectrum.

Hi, I'm new to the list, so please bear with me :) I am currently in a fairly unusual project: For a my master's studies at Hanover University, I and a partner have been given the task of evaluating MANET (Mobile AdHoc Networks) simulation possibilities using the Half-Life 2 engine. That means we're supposed to create some kind of a radio wave model, ad-hoc connections and (ideally) IP networking. The result would then be a realtime 3D simulation of a WiFi or Bluetooth ad-hoc network. Luckily, the OSI layer model allows us to break the task down into smaller subtasks, ranging from the physical to the application layer. Probably, everything above Layer 3 or 4 is not interesting for our purposes. So far, we are still thinking about how to implement the physical layer in HL². What we need is a free-space propagation model including packet travel through air and if possible re- and deflection as well as materials support. Our idea was to hook into an NPC's OnTakeDamage function and use explosions (which seem to be circular or spherical in their pressure wave) as "packet emitters". The RadiusDamage stuff seems to be ideal for simulating a free-space propagation for radio signales. We would then have to put some kind of payload data into the explosion event... or something like that. Does anyone on the list have any insight if this approach is feasible at all? Do you have better ideas for us? Thanks for your input, --ck -- http://www.de-punkt.de [ [EMAIL PROTECTED] ] http://www.stormix.de PHP-Anwendungen sind gefährdet!
