Hey and welcome!

Compile logs are for the most part humanly readable and will contain a lot of useful information about the compilation process.
Near the end of the log you have the message:

There was a problem compiling the map.
Check the file C:\Program Files (x86)\Steam\steamapps\common\Half-Life\valve\maps\Q3.log for the cause.

which means you had one or more problems in the map which will be described further up in the log.

The quickest way to find problems in the log is to open it in a text editor and search for "error" (serious problems preventing compilation) and then for "warning" (less serious problems that doesn't prevent compilation but can cause issues in the compiled map).
The messages you find tend to be very self-explanatory and often tell you how to fix them. In other cases when it's more unclear you can look up the error message at Tommy14's compile error page.

In your case you'll find the warning message: "Warning: === LEAK in hull 0 ==="
That means there's a leak in your map and you can use this guide to find and fix it: Tutorial: How to fix those leaks

---

As for why the map turns out fullbright when there's a leak, it's because leaks prevents VIS and RAD from running, and RAD is the compile tool that generates lightmaps. Without lightmaps, the map becomes fullbright.

i am new to mapping, (J.A.C.K) and My map is stuck in fulbright no mater what i do. here is the log:

thank you

It does exist in GoldSrc, it's used to halt execution of the following commands until the next frame (often used complex binds to prevent multiple commands happening on the same frame).
I don't think the GoldSrc version takes any arguments though, only ever waiting a single frame.

I believe the wait command doesnt exist in GoldSrc if I remember correctly

Console command "wait" not working properly in Half-Life 1 (not source version). For example, in line "speak black; wait 100; speak mesa" only last command executing (other parts just skipped). In source version all works perfectly

Thank you! It'd still be interesting to figure out scenes.image some day, but for the time being, the SDK sources have helped me already (it's an env_microphone at Breen's mouth and an info_target at the screen).

In the SDK sample content there's a copy of d1_trainstation01, which has the breencast setup in it; It's a prefab Valve used so it ought to be consistent across all the different choreo scenes.

As for actually extracting stuff from scenes.image, I have no idea if it's possible. You might have to track down an older build of the game from before that system existed when the vcds were all loose files (Or it might be in one of the SDK bases? I can't recall)

I'm trying to get a choreographed scene from HL2 working in my own map, but I have no idea what target entity is which. So I figured, fire up faceposer real quick and look at the scene. No such luck, it's all packaged into the scenes.image, which I have no idea how to get the scenes out of to inspect them with faceposer.

The faceposer documentation on the Valve wiki is nonexistent (it literally redirects to Category:Choreography), so I'm all out of ideas. Any advice would be much appreciated.

(More specifically, I'm trying to get Breencasts working; I can make Breen read the lines (he's target 1), but I can't get the audio output with the reverb that's loud enough to be heard across the map working)

P.S: I've tried decompiling some HL2 maps to find out, but bspsrc crashes with an index out of bounds error IMMEDIATELY.

Put a trigger close to the zombie instead of trying to have it when taking damage. I'm guessing it's because no interruptions disables taking damage, and the zombie didn't realise it was even supposed to have been hit.

Just go into source and put it there or jsut put it into general

Well, source 1 and goldsrc tutorials are there too, and I dont wanna keep switching sites, just if I want to see different tutorials, and I have looked on there and habent understood a single thing, I learnt it all by myself, which I think should be self explanatory ( aka tutorials should be made simpler)

To be more specific, I wanted to make a thread about combat and arena design in the Half-Life games, both GoldSrc and Source, and I have no idea what forum that would go into. It doesn't seem misc enough to into General Discussion, not engine-specific enough for the Source/GoldSrc forums, and Maps and Mods forbids mapping questions... what's a gal to do? Flip a coin and pick an engine subforum?

The Valve Developer Community already has articles on Source 2 development: https://developer.valvesoftware.com/wiki/Source_2/Docs

That's the place to be for that engine.

I would love a category with Source 2 Tutorials, I would make them myself, I would just need someone to set up the page since I dont understand how to, it would follow a similar structure like the goldsource tutorials. I would also make some tutorials on the layout of hammer, whats changed and how to use it for cs2

It may seem like a trivial solution, but please do share your solution in case anyone should find this thread in future with a similar issue.

i was able to figure it out but no delete post button uh oops

actually think i might make it something other than taking damage since you could destroy the corpse but thats kinda irrelevant stop talkijg

I'm trying to trigger a scripted_sequence when a monster_zombie takes damage, and it's playing the idle animation but continues it when taking damage. For the scripted sequence apart from defaults the properties are
Target Monster: (the zombie's name)
Action Animation: eatbodystand
Idle Animation: eatbody

And the zombie has Take Damage for trigger condition if that matters, and I've tried setting both TriggerTarget and Target to the scripted sequence's name, but neither seemed to do anything.
oh yeah also no interruptions is on so it doesnt just jump to normal behaviour

me here after making this public, maybe realising the title isnt descriptive enough
oops

okay woo edit 2 since i forgot this
for some reason the zombie always faces the same direction, despite changing both the zombie's rotation and the sequence's

Hi and welcome!

First of all it sounds like you're using very old compile tools (as it doesn't automatically add CLIP to the sky), I highly recommending switching to Vluzacn's ZHLT v34.

Secondly to make invisible walls and such it's better to use CLIP texture. It creates a collision mesh in the shape of the brush it's applied to.

As for the reason why the {invisible texture didn't turn invisible, it's because the brush covered in it must be tied to a solid entity such as func_wall with the render mode set to Solid (this render mode removes the masking colour from {-prefixed textures, most of the time this is the blue colour). In most cases it's better to use NULL texture instead (removes the face completely).

Hey, this is my first post here. Hi. uh lets just start
So, I'm trying to make my first map, which starts with you outside briefly before going into black mesa or something. But it was weird to just spawn in a random place with no apparent entrance, so I'm making a hole in one of the cliffs that seems to have collapsed after you went through it, with the skybox visible through the rocks. Thing is, there's holes in the rocks. So, I'm trying to make an invisible wall because otherwise you can crawl through into the skybox which is for some reason made of water???

"Aha, I can use the invisible texture! That'll work!"
Turns out the invisible texture turns black when you try playing it.
So, could someone tell me how to make invisible walls? I tried searching around the internet but closest I found was a wall you can walk through...

What others said. Not dead, but less active than before.

I end up being alone because people are on social media. And I'm not a social media guy, quit it around 2017

Still posting my maps here, starting with example maps in 2014 and my first finished map in 2018

This is the only place, so far, that I can interact with people from around the world. The other places I interact are art websites

Oh yeah, I miss that. The last time I did a lot of mapping was when RTSL ran competitions regularly (I wasn't on TWHL then), that always helps get over writers block (mappers block?).

Hello,

How would I determine the model of a given CBasePlayerWeapon?
I'm trying to drop the models of the weapons a player had when they died.

Currently I have a switch that uses the classname and hardcodes the name of the model -- which isn't quite ideal.

Thank you.

less SCROLLIN', more MAPPIN' !!!
we need a map competition every 3 months >:D >:D >:D

When making signs you pretty much have to do it using brushes.

A common and easy technique is to make it a thin brush and tie it to func_detail and set Passable to Yes (zhlt_noclip 1). This prevents it from both chopping the walls it's placed on, as well as generating unnecessary clipnodes the player might collide with. Another technique is to actually embed it in the wall and either use the Clipping Tool to cut out a hole for the sign:

---

or, a bit more advanced technique is a sort of mix of the two. Embed the sign in the wall as with the second technique, but instead of clipping a hole in the wall leave it as it is and tie the sign to a func_detail again. This time set the Detail level (zhlt_detaillevel) to 1 and the Priority when faces overlap (zhlt_coplanarpriority) to 1 as well.

It will do a lot of Z-fighting in the editor (flickering) but in-game it's the sign that will be visible without any Z-fighting (because of the zhlt_coplanarpriority keyvalue).

I've uploaded the new archive with fixed skill.cfg.

I also added user.scr, so Advanced tab in player settings has some configurable options.

for some reason the sprite its really big, like x3-x4 scale of a normal grenade.

Do you mean the HUD sprite? There's a HUD autoscaling feature, but it's turned off by default, so it shouldn't scale unless you change hud_scale client cvar.

Thanks for reporting. Yeah, that's weird. I'll look at it and make a fixing release when I find out what causes the problem.

For now the fix is to replace all tab characters in skill.cfg with spaces.

In the past decade phones have practically enslaved us. It is now impossible not to check your phone several times per day. People mindlessly scroll through stories, reels and other forms of short form media shit.

This. I used to laugh it up a long time ago, but at some point I realized I easily end up spending 5-6 hours on average just staring at the phone reading any unread public chat messages, or checking out the memes. Even when everything's been read, I end up re-reading old stuff instead of doing something more interesting.

ohh that makes sense. Just gotta use an actual decal and not just any texture. Thanks!

The problem has nothing to do with the compilers (you'll likely find the infodecal entities in the entity lump of the compiled BSP).

What is actually happening here is that decals only work with the special textures from the game/mod's decals.wad file, and you've used normal textures from halflife.wad

I put some infodecals on the wall and they show up in JACK but not ingame.
I tried using SDHLT and ZHLT and nothing has worked.
Bullet holes appear ingame but not the infodecal entities created in Hammer.
Is there any way to fix this? Compiler log:
https://pastebin.com/raw/CM1p7mXM

Seems like efs didn't post an update here so I'll do it.
The problem was the landmark. I assume that particular issue was fixed then.

just put your questions in the forum here

I got your DM.

So you're having trouble with level changes where the player spawns at map origin in the second level.
In that case you should check that

• There is an info_landmark in both levels and named the same (without any special symbols or non-latin letters)
• Both levels have a trigger_changelevel pointing to the corresponding map of the level change (i.e. the first level pointing to the second, and the second pointing to the first). It must do this even for one-way level transitions (in this case the second level's trigger_changelevel can be placed outside the playable area to keep the player from going back).

If you haven't already, check out Tutorial: Changing Levels guide as it's very helpful for learning about level transitions.

There are plenty of people here that can help, depending on the problem/issue.

Start by telling us what problems you've been having, one at a time.
Tell us what you wanted to do, what you expected to happen, what you've tried, and what actually happened instead.

Can someone help me in making a mod? There's some problems or issues that I could not solve.

Hey! i really love your work, this level of easy customization its awesome, i downloaded this recent version (yesterday's) and i found a bug, the grande of the mp5/m4 grenade launcher doesn't do any damage (player itself and/or monsters) and for some reason the sprite its really big, like x3-x4 scale of a normal grenade.

EDIT: And i don't know if its just me, but in the sample mod, no matter what i try like executing the skill.cfg, or skillopfor.cfg, or whatever, all monsters health and parameters are 0 in every map. In the console it shows all the overriden values:

"sk_agrunt_health1" is "0"
"sk_agrunt_health2" is "0"
"sk_agrunt_health3" is "0"
"sk_agrunt_dmg_punch1" is "0"
"sk_agrunt_dmg_punch2" is "0"
"sk_agrunt_dmg_punch3" is "0"
"sk_apache_health1" is "0"
"sk_apache_health2" is "0"

etc.

Changelog

Half-Life Anniversary changes

Some Half-Life Anniversary changes were merged from https://github.com/FWGS/hlsdk-portable. Thanks @nekonomicon

• Improved handgrenade throw physics.
• Improved spawn spot randomization in multiplayer.
• Fix gauss sound on level transition.
• Added HL anniversary fix for pushable acceleration
• func_vehicle implementation
• Fixed snark throwing when player is on the edge.
• Applied new satchel controls.

More changes related to HL anniversary will be merged in the next version.

Cvar changes

• New client cvar cl_satchelcontrol to control the preferred control scheme. 0 is for legacy, 1 is for anniversary.
• Changed how pushablemode cvar works. Now 0 means anniversary mode (default), -1 means legacy mode and 1 means XashXT mode. The special value 2 (which meant the SoHL mode) has been removed.

Configurable features

• gargantua_larger_size - when enabled, make Gargantua's size equal to one from Opposing Force. This fixes the problem with some projectiles (e.g. shockroach and hornetgun ones) not properly hitting the monster.

Other changes and fixes

• Shock trooper and voltigores now have a 'hate' relationship to the player instead of just 'dislike'.
• Picking up items by +use (when the pickup_policy value is not 0) is no longer allowed through the walls.
• Fixed a bug when colorable crosshair didn't restore properly after using a func_tank.

I remember running into this a few times before, years ago, but I just ran into it again, recently and today, and it's been driving me nuts.

There's a bunch of props which are supposedly suitable for prop_static (as in, the model browser lists them as such), that apparently aren't. When I place them in the world as prop_static, they straight up don't appear in the game. Neither the compile log nor the in-game console show any errors, they prop simply doesn't show up.

Affected models are, among others:

• models/props_wasteland/controlroom_filecabinet002a.mdl
• models/props_c17/lockers001a.mdl
• models/props_junk/trashdumpster01a.mdl
• models/props_wasteland/kitchen_shelf001a.mdl

So far, all models I've seen this happen with are models that are listed as physics and static props in the model browser, and they're all official Valve models shipped with and used in the games.

For each of them, I have to use prop_physics with all the flags that make it as static as possible, or prop_dynamic_override, both of which are computationally less efficient than prop_static and just irritating workarounds. Furthermore, the only thing I've found about this on the web is this Reddit post, which does suggest a solution, but a complicated one (using a different compiler from a different game), and which I'm not sure is even applicable, considering EP2 already runs the Source 2013 branch of the engine.

If anyone has an easier workaround, or can tell me why this is happening in the first place, I'd be very grateful.

Well said.

monster_urby said:
TWHL is one of the oldest Half-Life modding communities and in recent times it certainly has been quieter around the main site and forums. The site itself is not as active as it once was, but remains a useful resource with the wiki, map vault and competition dashboard.

For me it's kind of amazing that TWHL still exists. It's one of the first communities that I've joined online, less than 6 months after having an internet connection (2006/2007) with 32 kb/s speed. It brings back a bit of nostalgia after those phpbb/vbulletin forums. There are still many communities left communicating through these forum types, but a lot of them died. In my country, there were big communities around hardware/software/gaming magazine forums. In the early 2010's most of the physical mediums died, and the communities slowly started to fade away. I'm guessing this is what happened in other countries too.
Then the forums slowly started being replaced with chat platforms, one of the most popular being Discord. Although highly practical in some sense, I believe it's just another symptom of the dopamine-hit-style environment the internet is today. Discussions fade into a black hole, unlike these forums where you can search, structure and have some statistics. Discord is a forum, irc and teamspeak/ventrilo server all in one. All-in-ones don't ever do one thing well.

People also grow up and there's very little time to devote to niche online communities if you have multiple interests.

Then the social media garbage started and really took off in the 2010's, sucking people's time. Nobody is immune from these trends, I myself joined Facebook because high school friends pushed me to do it. Then Instagram because a college girlfriend told me to. Now I reluctantly joined Threads because some people I know post there. I never joined TikTok and I hope I never will.
In the past decade phones have practically enslaved us. It is now impossible not to check your phone several times per day. People mindlessly scroll through stories, reels and other forms of short form media shit. I do it too, and I've done it against my better judgment until I had enough humility to recognize that I am addicted to my phone, not unlike others. What slowly got me into the addiction were a few tough mental months where social validation from online forms provided me the feel-good emotions I needed to push through the days. When I work, the only solution for focusing is to close the internet connection on my phone and put it away from my field of view.

I've been also following AI trends for a few years. The hot shit right now are LLMs and diffusion models (a.k.a chatgpt/llama/mistral, stable diffusion/ midjourney/dalle a.k.a generative ai models). The internet is slowly becoming now a cesspool of generated robot regurgitated data deluge and fake art. Where once the internet was a source of good information and radical sincerity, filled with mostly tech or trade-inclined people, it's now... I don't even know how to describe it anymore. My feeling about it is how Mark Hanna in Wolf of Wallstreet describes the stock market:

Fugayzi, fugazi. It's a whazy. It's a woozie. It's fairy dust. It doesn't exist. It's never landed. It is no matter. It's not on the elemental chart. It's not fucking real.

Whoever is able to still ignore all of this and focus on their or these little community gardens, they can consider themselves trully blessed.

Technology robs us more time than the government and other necessary human chores ever will.

So considering all of this - it's a damn miracle people still come to TWHL to discuss and create stuff around an engine that's 25 years old.

trigger_changelevel's 'Change Target' attribute can be used to trigger an entity on the next map.

20 years of Half-Life mapping, and still learning something new

Contrary to what it suggests, trigger_changelevel's 'Change Target' attribute can be used to trigger an entity on the next map.

Edit: Here is an example map with Archie's suggestion of using func_wall_toggle.

Hey, just wanted to say that i find my solution months ago.
What i wanted is to show the amount of grenades without select them, so here's my code writed in SendAmmoUpdate in player.cpp :

void CBasePlayer::SendAmmoUpdate(void)
{
for (int i=0; i < MAX_AMMO_SLOTS;i++)
{
if (m_rgAmmo[i] != m_rgAmmoLast[i])
{
m_rgAmmoLast[i] = m_rgAmmo[i];

ASSERT( m_rgAmmo[i] >= 0 );
ASSERT( m_rgAmmo[i] < 255 );

MESSAGE_BEGIN(MSG_ONE, gmsgGrenades, NULL, pev);//send message with the hitgroup they were just hit
WRITE_BYTE(0); //For some reason, there is some weapon ammo that is impossible to get his index, so instead of writing the grenade index, we just put a 0
`WRITE_BYTE(V_max(V_min(m_rgAmmo[GetAmmoIndex("Hand Grenade)"], 254), 0));`
MESSAGE_END();

// send "Ammo" update message
MESSAGE_BEGIN( MSG_ONE, gmsgAmmoX, NULL, pev );
WRITE_BYTE( i );
WRITE_BYTE( V_max( V_min( m_rgAmmo[i], 254 ), 0 ) ); // clamp the value to one byte
MESSAGE_END();
}
}
}

The gmsgGrenades can be replaced whit gmsgAmmoX , but i created a separated code just in case.

So there has to be a config file already in the game to do that?

You can use an env_global. It's an entity that acts as a switch, whose state is shared between level transitions. There's a tutorial, too: Tutorial: Globals.

Using that, a multisource, and the "Master" property on the trigger_multiple, you can disable it after the player activates it by entering the area, and reenable it once the player leaves it and enters the other area.

I'm hazy on the specifics, but after some experimentation with entities you should be able to engineer a solution on your own.

Sounds pretty complicated though: hard to set up and utilizing a lot of entities per one such transition. Use such setups sparingly.

The logic_auto entity has an "OnMapTransition" output that you can fire to trigger an entity every time the map is entered, I think that should do the trick.

I Will try!

Could you provide a screenshot of the error?

Hammertime is like normal hammer, although a bit more modern, I would if you want ofcourse, include some articles for some Stuff about Hammertime
