Fun concept. You'll probably be better off creating your own entity and creating your own method for hit-testing, overlap, etc. The OnTakeDamage and CEntitySphereQuery are pretty limited in the fact that it'd be harder to calculate world (i.e. walls) disrupting the radio wave. You'd probably do well building a mesh pragmatically for the radio wave and manipulating it via shaders than any other method. The issue with this is that it is more time consuming but would allow for a more accurate model.

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!
