[hlcoders] Detecting point is outside world
Hey all, very simple question that I can't seem to find the answer to - how to tell if a point is outside the game world or not? I've added an ability allowing players to teleport a short distance, including through walls, to our HL2MP OB mod. This is great, and the code successfully avoids getting the player stuck inside world brushes or anything else when teleporting. It is unfortunately possible for them to teleport to completely outside the world geometry, and I can't work out how to stop this. I've tried my hull traces using various likely-looking masks collision groups, and have looked at all the UTIL_PointContents flags, but I can't see how to determine if a point is outside the world or not. I've also looked through gamemovement.cpp, as players don't fall when they teleport outside the world, so something must be stopping them, as they aren't in a solid - but nothing jumps out at me. So, does anyone know how to determine if a point / trace / entity is completely outside the world geometry? The best hacky method I can come up with is testing if a several-thousand-unit-long trace can be done in any direction (up/down/n/s/e/w), and if any can, assume its outside. I'm sure there's a point contents method, but I can't work it out. Help would be appreciated.

I've only just got into the plug-in scene but I've got several years experience in C++, C# and Java. Thing that I'm confused about, is if I'm missing something. I was looking at in-game menus and saw a tutorial on sdk source wiki site. It uses the user message ShowMenu. It works fine but how did the person figure it out when there's no example of it being used in the source code. In trying to figure it out I looked up UserMessageBegin function only to find that there's no code for the function. Instead I find a interface class for a DLL. So I can't see a working example (where the functions used) and I can't see the functions code, so how on earth does anyone figure out how to use the function? I was also looking at colouring in user messages. I think UTIL_SayText2Filter does that but it uses the user message SayText2. That hasn't been declared in the source although because there's SayText it might not matter. I across a forum where they figured out you can use escape characters like \1 for yellow and \2 for green. Once again there's doesn't seem to any example of that in the source code. What I want is to be able to create in-game menus and user messages with colouring (like in mani plug-in) but from what I see, I can't see how you can figure that out. When you don't have access to the complete code (you get a bunch of interfaces with no explanation).

Re: [hlcoders] Detecting point is outside world
Andrew, You could make a custom invisible (solid) tool brush (like teleport_clip) or see if you can test against player_clip perhaps that you would use in all your maps both in areas outside (or just in outside walls) and inside where you don't want players going. Players attempting to go past that brush would be not allowed to teleport, bounced back to their starting position or just stop a certain distance from the brush. I would guess that you could also use tools/trigger on a custom brush entity like trigger_teleport that you can test against, see if any of that code might be useful. You must have some sort of testing going on already to make sure players don't teleport inside walls, solids, models (hollows inside the map structure?)and each other. This way all you have to add is a (hopefully simple) test and make very simple changes to your maps and as a result you would have pretty good control over this feature. qUiCkSiLvEr - Original Message - From: Andrew Watkins To: hlcoders@list.valvesoftware.com Sent: Thursday, September 18, 2008 12:19 AM Subject: [hlcoders] Detecting point is outside world Hey all, very simple question that I can't seem to find the answer to - how to tell if a point is outside the game world or not?

Re: [hlcoders] Detecting point is outside world
You only need to do 2 traces on one axis. Since a map is supposed to be completely enclosed. Aslong as the trace hits a brush in both directions, then they are inside the world. You could also assume that aslong as a player is not nocliping and their Z velocity is under like 1000 they are in the world. If both are false, then you do the trace check, if the trace doesn't hit twice then kill the player. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Watkins Sent: Thursday, 18 September 2008 5:20 PM To: hlcoders@list.valvesoftware.com Subject: [hlcoders] Detecting point is outside world Hey all, very simple question that I can't seem to find the answer to - how to tell if a point is outside the game world or not?

The only possible solution valve could do for such a thing is a version system.

Re: [hlcoders] Detecting point is outside world
Pointcontents should return CONTENTS_SOLID if you're in the void.
Part of the map compilation process is to 'fill the outside' with
contents_solid.
So a simple
If ( UTIL_PointContents( position ) CONTENTS_SOLID ) )
{
In a solid, or the void
}
Should work.
Noclip around and test it with this command:
CON_COMMAND_F( dbg_contents, dbg contents, FCVAR_CHEAT )
{
CBasePlayer *pPlayer = UTIL_GetCommandClient();
if ( !pPlayer )
return;
int contents = UTIL_PointContents( pPlayer-GetAbsOrigin() );
if ( contents CONTENTS_SOLID )
DevMsg(in solid\n);
DevMsg( Contents: %i\n, contents );
}

Re: [hlcoders] Old recorded demos
Wouldn't you also need the appropriate client/server libraries that match up with the version you recorded the demos in?

Re: [hlcoders] Old recorded demos
I dunno. I'm guessing it could be even simpler than that. For the demo's you've only got to really record what things looked and sounded like. So things like models, angles, positions, gestures. You don't need to know all the internal data like reload timings etc.. with the exceptions of data for HUD stuff, like health and ammo counts. garry On Thu, Sep 18, 2008 at 4:24 PM, Nick [EMAIL PROTECTED] wrote: The only possible solution valve could do for such a thing is a version system.

Re: [hlcoders] Old recorded demos
Yeah, exactly. HUD wise all it's gotta do is poll for changes (Likewise for other networkvars). Find some way of storing all their values in a structure that wont depend on game version.

Re: [hlcoders] Old recorded demos
Yes, every new update to the demo system would mean including a new DLL as well as keeping all of the previous DLL versions in existence. It is a small price to pay to keep all of the Demoversion(insertversionshere).dll on the hard drive. Hard drives are getting half as expensive every 2 years. I would gladly have even 500mb of demoversion(1-84).dll if I knew that demos would last forever. I should have made my previous email clear about keeping all previous DLL. Sorry.

Re: [hlcoders] Detecting point is outside world
I don't think you can use traces because the map enclosure isn't necessarily a convex shape. So you could imagine a point where a trace in any direction would hit brushes which is still not a valid position for the player.
