[hlcoders] Sending data from client to server
Hi guys, I'm trying to get NPCs to work with the player's lightlevel. As far as I can tell, the WorldGetLightForPoint() function can only be called from the client, so I figured it'd be easier to catch it client-side and send it back than try and hack the engine calls. Now I can't figure out where to store it so it'll get passed back to the server DLL (this is SP only, by the way)... anybody know how to do this? Thanks in advance, James -- James Freedman [EMAIL PROTECTED] http://www.seascape.uk.net ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
Re: [hlcoders] Weapon ballastics
Well, you could make it go any speed you like if you're coding it, but real bullets travel at something like that speed. r00t 3:16 wrote: I was looking at where the tracelines happen.

So there's not tons of error there, but if you need more precision just subdivide dt and iterate. If you use vphysics it will do it's own approximation for the motion which you cannot configure.

This is a multi-part message in MIME format. -- [ Picked text/plain from multipart/alternative ] At the moment, they don't have a speed - they're instant hit. If you wanted to modify their speeds, you'd have to make an entity like crossbow_bolt and make the weapons create an instance of that for every bullet instead.

RE: [hlcoders] Possible to not use weapon script files?
Well, you're looking at overriding the ReadEncryptedKVFile() function in weapon_parse.cpp - or at least commenting it out. Of course, you'd then have to manually set all those variables in the weapon's constructor function, which sounds to me like a fairly time-consuming and mundane task.

RE: [hlcoders] Possible to not use weapon script files?
Sure, if you're paranoid it's nice to hide things in the DLL... But I'd say that at release-time, packing them into a GCF is good enough. A large proportion of your user base either doesn't know how to change those script files, or quite frankly doesn't care...

Re: [hlcoders] Steam: Technology failure
That's all very well, but I hardly think filling up *our* inboxes with complaints is going to help your cause. Post on anti-steam sites, start a petition, e-mail Valve - these are all valid ways of getting your point across. Diluting this mailing list with off-topic, in my opinion, isn't.
