that is really cool. unfortunately, in order for mods to be truly modular in a way that would work for that, you'd really need to code with that modularity in mind. :( 

 

That was my conclusion as well.

I did a bit of work with these (having them visible and used for other things as well) and decided that the hack is just what it appears to be. The position is never updated just out of laziness rather than for a specific need.

I tested resetting their position to see if it changed something in the map but couldn't notice any difference. But my knowledge is more limited than yours on these matters. 

setting force_relink (eg, triggering a teleporter) or reloading a game will force those entities to be relinked in whatever position that they're currently in.
if they're then moved back then they'll be non-solid in their original location.
if neither of those two events happen, then the entity's pvsbits and areanodes won't change, so as long as its reset to the original position it was setmodeled in, it'll be fine.

additionally, fte can trigger relinks from vid_restarts (worldmodel is reloaded, so the old pvs is possibly no longer be valid). I assume other engines might do the same. 

setting force_relink (eg, triggering a teleporter) or reloading a game will force those entities to be relinked in whatever position that they're currently in.

I can understand the concern with save games, it seems to me that the hack should fall down there. I tried the following to test it:

1) trigger a togglewall to "become non-solid" i.e. leave the map
2) make a save file
3) load the save file
4) trigger the togglewall again to bring it back into the map

This doesn't exhibit a bug, the wall worked fine - it collided with me, even though it shouldn't be in the correct areanode. Is there a chance that areanodes are calculated with the coordinates "wrapping round", so that the precise distance displaced is saving the day?

The position is never updated just out of laziness rather than for a specific need.

I wondered if the intent might be to avoid "trigger in clipping list" type errors, the kind caused by changing things during a physics update. Potentially a togglewall can be triggered during a touch function. 

that's interesting because the func_laser in rubicon2 calls setorigin in its use function, and i don't think it causes any problems. 

I'm mostly backing this up with a comment from client.qc

// we can't move people right now, because touch functions are called
// in the middle of C movement code, so set a think time to do it

But I guess I must be misinterpreting it if I'm banning setorigin during a touch function, or else how would a trigger_teleport hope to function?

Is it changing the solid status of an entity which is forbidden then? Is it particular to messing around with a trigger? 

i remember having problems with doing setorigin in touch... but i think it only happened with triggers of some kind. sorry, really long ago, forget all the details. :S 

SV_TouchLinks walks through the various triggers in a fairly lazy way. you can relink non-triggers inside trigger touch events, but if you relink any solid_trigger entity there then the loop can end up referring to the wrong entity, potentially resulting in references to null or infinite loops. sometimes you might be lucky and get away with it, it really depends on the ordering.

this can be seen on e2m2 - shoot one button then jump across and you'll touch a trigger that killtargets another trigger, resulting in a crash.

non-triggers touching non-triggers should be safe, as the node-walking is separated from the qc callback, limiting movements to touch only one other solid entity.

because triggers and non-triggers use separate node lists, relinking the player won't hurt the trigger lists, which is how come teleporters never cause any problems.

by relinking, I mean calling setmodel/setsize/setorigin, or alternatively removing an entity.

bug-fixed engines will probably just build a list of the triggers that need touching and *then* trigger the events if the triggers were not removed by a different trigger, thereby avoiding the crash at the risk of dropped touches (if its a player then it'll just get touched next frame anyway, although monsters might not re-trigger it any time soon if they stop walking at that point). 

Ok, Im needing something that can remotely rcon Quake engines, mainly pq for now. Turns out if you have a server on 2 ports, the rcon commands always wind up heading to port 2600 by default. SO you can use rcon_address and rcon password fine, and even status will show up ok on the non std port but any command telling it to change a setting winds up going to port 26000. SO I found this small app that claims to be able to rcon to Quake servers: [ http://www.codeproject.com/Articles/21885/Send-RCON-Commands-to-Quake-Based-Games ]

They want an email address sand pw so the dl is accessable, so I think any email address will work, it dont seem to send out a verify, then you can just dl the code.

So its C language, and I have had such rotten luck using Visual Studio trying to compile a Quake engine, but since this one was small , decided to try. Turns out I have Visual Studio 10, and it said it needed to convert, which it did, and seemed that it was successful, so I clicked on the proj file, and did a build, and to my amazement, it built an exe in bin/release and also in obj/release. However my excietment was short lived, as the app does run, when you enter a server address and pw and command, it locks up indefinately and has to be shut down in task manager.

Anyone here have some advice on what Im doing wrong or is the code itself just crappy? 

Is this possible? I notice an entity member idealpitch but changing it doesn't make a difference.

I'm trying to add gun climb, where firing a weapon makes the player look up. 

yup, totally possible. set .fixangle to 1. the player's view will snap to whatever is in .angles. 

nnnnnoooooo!
you can spam fixangles as much as you want. each time will cause the player's view to snap to something that they were not aiming at at the time.
this is especially bad over a network. you simply cannot use it for only pitch or only yaw.

it can be kinda rough even in single player, even a single frame's delay will snap you back to your yaw angle from the previous frame. repeat and your angles are now locked.

there is a .punchangle field that you can use to bias the pitch angle, however, it tends back towards 0 and there's not really anything you can do about that. It WILL judder regardless, especially in QW where you'll probably overcompensate and cause it to go completely haywire.

if you want full control over the camera angles, or the client->server angles, the only place you can reliably do that is clientside. Ie, in csqc. Doing it serverside will just result in fighting with the client, and the lag (even in single player) will prevent you from reconciling. 

Okay, so I tried fixangles and the behavior is very unexpected. Spike (is that you, Spoike?) is correct, I've tried it in Quakespasm, Darkplaces, FTEQW and it does snap to something i wasn't aiming at (even after using angles/v_angle = angles/v_angle + 'x y z') in all of them.

punchangle is also cosmetic and doesn't effect gameplay. I'm messing around WriteEntity() now... will let you know how that goes... 

Got it i think. After I calculate the new angles, I use WriteByte ( MSG_ONE, 10 ); Now, I dont know if this adjusts v_angle or angle, but hey... it works for now. Here is the code chunk for anyone interested;

ang_x = -8 - random() * 2;
ang_y = random() * 2 - 1;
ang_z = 0;
ang = ang + self.v_angle;

msg_entity = self;
WriteByte ( MSG_ONE, 10 );
WriteAngle( MSG_ONE, ang_x );
WriteAngle( MSG_ONE, ang_y );
WriteAngle( MSG_ONE, ang_z );

I'll throw together a tut soon (hopefully) 

I'm wondering why is the W_WeaponFrame() function called in the PlayerPostThink() and not in the PlayerPreThink(), moving it doesn't appear to make a difference. Is it arbitrary? Or, did the developers intend to queue command processing for next frame after all entities had been processed?

I know pre and post run before and after player physics processing (or is it before and after all entities have had their physics processed?), when does the animation tie in to the flow of a single game step? In my own WIP game engine, the flow at every step is:

1) Capture events
2) Process logic/AI for all 'actors'(entities)
3) Animate all actors
4) Run physics on all actors
5) Render everything 

For my mod, I made sure that each weapon pickups have their own sounds. Same thing for armors and ammo boxes.
It works without a problem on darkplaces, but picking a weapon in quakespasm stops the current game and displays this:

Here's my code for armors:
http://pastebin.com/7DywCzPm
My code for ammo boxes:
http://pastebin.com/eKKZUVqu
And finally, my code for weapon pickups:
http://pastebin.com/Mwr4NtnG

As you can see, I used for all of them that "self.noise" trick that allows me to add different sounds for each items.
I find it wierd because picking up ammo boxes with that method in quakespasm doesn't crash it, even though they use the same technique. At first I thought that was because the whole "self.noise" root declaration was put after all the individual weapon pickup lines, while it was put before for the ammo boxes. So I tried to do that for the weapons, but while testing in darkplaces the weapon pickup sounds don't play. 

you need to precache sounds in the spawn functions, not the touch functions. Your armor and ammo code are doing it correctly. Your weapon code is doing it wrong. 

 

I had someone test my first schlossherr map, and he picked-up the MegaHealth item in my map, and because they share the same itemslot, he got the BFG as well.

With this, coupled with the fact that I want 2 extra-items after being done with the BFG, I remembered that mission pack #2 had an items_2 thing that lets you store more items. Thing is, my google-fu is weak and I can't find its sourcecode, even in ModDB. Would anyone be kind enough to link me to it?
Another thing, since I'm adding additional weapons, how can I add extra HUD icons?

One last thing, Back when I was asking questions about my BFG problems regarding the projectile penetrating enemies, I recall someone saying something like "destroy the projectile which makes a new one with the same trajectory as the original projectile", but what's the way to pick up those coordinates and use them? 

I can't seem to find a regular download for the rogue QC either, but I did find a github account with it

https://github.com/bazilio-ua/q1.progs/tree/master/original/rogue/progs

It looks like some modifications have taken place since, but if you track back to the initial commit it's probably how the original files looked. Hopefully...

Another thing, since I'm adding additional weapons, how can I add extra HUD icons?

You only have three options as to how the HUD works. You can have the HUD like it is in vanilla, or the HUD from mission pack one, or the HUD from mission pack two. You can customise the icons themselves, but there is no way of rearranging them or adding more than what the mission packs have. The mission packs got special customisations to the engine code before the source was released, it's not something the QC gives you any ability to change.

Incidentally, items2 was actually introduced in hipnotic, not in rogue, so you want the mission pack 1 source code really! 

Re-looking at it, and I have items2 defined in hip_def.qc (included in progs.def), which begs the question: if it was, then how come I have trouble adding items then? Or should I put my new weapons and items declaration from defs.qc to hip_defs.qc? Or is there something else that I'm missing? 

Two minor ideas. Firstly, make sure that it's being included in the compilation. Take a look at the progs.src file and check that hip_def.qc is in there.

The other think to think about is that you select between the three HUDs on the command line, not in the QC. So make sure you're using -hipnotic or -rogue on your command line when you launch Quake. Also keep in mind that you need the end users of your mod to remember to do that too! I expect lots of people forget with Quoth and don't see the plasma gun icon... 

I'm asking what it is so I could properly made the BFG orb for my mod not to target them/make the orb explode on impact on them, and also so I can get around bleeding brushes when you hit them.
