Sm213 Low Gravity

Make a single player, low gravity map with the latest version of the SMP mod. You can set your level's gravity amount in the worldspawn. "Ziggurat Vertigo" (e1m8) was set to 100 but your map can be anything below 800 as long as it's bouncy, floaty and gib-filled! Make Sir Isaac Newton proud, GO MAP!


i enjoyed playing the E1M8 map with the low gravity and it is something i want to add to a map as well

i have tried to add a gravity key to the world spawn using "sv_gravity" and setting it to lower than 800 but it does not work (this only works from the console).

i used "gravity" as the key as well and that doesn't work.

can this be done by adding a key to the world spawn or does it rely on a mod or change in code?

how about maybe my key is not properly named/set up?

gravity for me needs to just be there without having to type in the console (like in E1M8).

i am running dark places as my engine
i am using trenchbroom v 2021.1
i am not running any mods
inside worldspawn i set sv_gravity to 100

EARP 

If you look at the sources of original game's E1M8.MAP or look at the extracted entities from E1M8.BSP, the worldspawn does not have anything related to gravity at all:

{
"sounds" "10"
"worldtype" "1"
"classname" "worldspawn"
"wad" "gfx/metal.wad"
"message" "Ziggurat Vertigo"
{...

The explanation is that in original game the low gravity for that level is set by the QuakeC code - https://quakewiki.org/wiki/Sv_gravity

I'm not sure if there's some sneaky workaround for that. 

@gila

yes, i know that it was done modifying the quake c code - no one put inside worldspawn a gavity key to get the results of e1m8.


with my set up gravity is not a feature that i have found using trenchbroom so it cannot be added from the worldspawn.

nothing pops up when typing in gravity or even the letter g (something should pop up if it is actually coded into it).

all i can do is type in the console to get gravity and that isn't good enough.

i have ran across info that says gravity can be turned on and off using a trigger but there are no trigger functionality within trenchbroom to do this. in my search i found a trigger called trigger_gravity but it doesn't exist for me.

the only way to get it done the right way is to copy what was done for e1m8 using quake c apparently.

the gravity thing is neat and would like to add it to a map in the future 

Low gravity needs a mod.

"Sm213 Low Gravity" announcement said that you should use the "SMP progs" which is dumptruck's mod intended for speedmapping. That progs has the gravity feature and you specify it in the worldspawn.

Link to that announcement: https://www.celephais.net/board/view_thread.php?id=10196&start=4313&end=4313#4313

There are probably other mods that also support gravity in the worldspawn, but I don't know off the top of my head which ones. 

regarding glass:

create a brush for the glass
make it a func_wall
set the "alpha" on that func_wall to a number less than 1, greater than 0

that should work -- in some engines. You say in another post that you are using darkplaces. I can't say whether this will work in that engine. Fitzquake and its variants will support alpha without a mod. There may be some engines that will only support it if running a mod that also supports it. 

@metlslime @dumptruck_ds, @gila

i appreciate the feedback,

quake is one of my favorite games, have played it a long time with my 2 brothers, one reason why i am working on building some maps (will be fun to play something that i created).

@metlslime

yes, i am using dark places

i tried to use quakespasam and when i tried to run it i received a message saying i had to buy a copy of something to run it (i already have quake so i have no idea why it gave me that message).

i have not used fitzquake i do not believe.

i see that it is referencing a mod, seems like i over looked that important piece of info my bad 

I'm not sure whats going on here. I've been playing with my lights then all of a sudden my map compiles fully lit despite having no leaks.

Here is my lighting log:

Did you delete the earlier *.lit file from your directory? 

So, I've been trying to get into some Quake mapping with TrenchBroom lately(I'm new to this entirely). However, I can't seem to get textures to work; They show up perfectly fine in the editor, but in-game I just get a checkerboard pattern. I've been trying this with the QUAKE101.WAD file.

I've been trying to find info on how to fix this but can't find anything. Here's the compile log if it helps: https://pastebin.com/6GtEByYu 

Okay well, this message from your compile log is a good clue:

*** WARNING 01: No valid WAD filenames in worldmodel

In Trenchbroom, can you look at the worldspawn entity and see if it has a "wad" property? That should point to the filename and path to your intended wad file.

If that seems correct, maybe it has to do with how you're compiling. Does Trenchbroom handle compiling for you, or are you manually running a batch file? If a batch file, perhaps it can't find the relative path to the wad based on the batch file's working directory. 

The worldspawn seems to be correct, and I've been using TrenchBroom itself for compiling.

Here's the parameters, I wouldn't be too surprised if something's off there. 

Okay, it seems to have started working once I moved the .map file to the base folder that I'm using, rather than in id1/maps 

Hey guys, just "finished" my first multiplayer map for Quake 1 and thought I'd post it here for some feedback.

Had a couple questions:
1. How do define my map as a multiplayer map? Its loading as single player map despite me placing multiple deathmatch start entities in the map.

2. How do I get my map to show up in the multiplayer map selector on Quake Remastered?

#1 - You must be in multiplayer/deathmatch mode. Can do this by setting "deathmatch 1" ( or 2, 3, 4, see https://quakewiki.org/wiki/deathmatch ) and then loading your map. If you start multiplayer game through the menu, that's what the game basically does, setting deathmatch no non-zero (or coop 1 for cooperative play).

#2 - Maps showing in the level select menu I think are configured in a special file you can find in \Steam\steamapps\common\Quake\rerelease\id1\pak0.pak\mapdb.json though I don't know if editing it is a good idea. In case you want to experiment, don't put the edited mapdb.json back into pak0.pak (although you can always verify installation in Steam and redownload 'wrong' files), but rather pack it into pak2.pak file 

Did you happen to add bot waypoints to this map? If not you might consider it. I haven't tried this but eventually I hope to do a tutorial on it.

Is there a hacky way (in vanilla or copper) to make a timed power-up (Quad, Biosuit etc.) last for the duration of the map after picking it up? 

Probably not - the code for powerups doesn't leave many loopholes. to set powerup state on a player, the code requires an entity with the classname of the actual powerup to touch that player. Only thing I could possibly see working is some kind of trick that teleports a powerup onto the player every 30 seconds, but not clear how to hit that moving target.

As an alternative, consider repeatedly respawning the powerup (using a simple hack), so the player can have the effect continuously, if only they go to pick it up every time. 

Ah-well, thanks anyway Preach. Back to the drawing board! 

I've got a setup in a map (for copper mod), whereby the player has to hit three buttons within a short timeframe in order to open a door that also only remains open for a limited amount of time. If the player doesn't make it through the door in time, they have to hit the three buttons again.

I've got a little black room outside the playable area with three doors (each with a wait of 5), a shooter and a shootable button. Each of the three buttons in the playable area target a trigger_relay. Each of these relays fires the spike shooter and opens one of the doors in the black room. Once all three doors are open at the same time, the shooter will be able to hit the shootable button, which targets the door in the playable area.

So far so functional, but I wanted to display a nice "2 buttons remaining" sort of message as is standard practice, so I also pointed all of the relays to a trigger_counter flagged to repeat. The problem is, the counter won't reset if the player does not complete the sequence in the limited time given them, so if they have another go without completing the three counts, the count goes out of sync.

I hope my description makes sense, because I hope somebody knows how I can fix this or rebuild it more effectively!

Thanks. 

You could instead have some physical representation of "button presses remaining" visible in the map, controlled by your logic (e.g. glowing rune plaques that change/disappear) ... it's not as clear of a message, but on the other hand some folks might even be happier with that sort of thing than with a centerprint. 

That's a really good idea and could also nicely convey the connection between the buttons and the door! 

Bit of self-promotion here: These map hacks should enable you to put the centerprint messages into your map. You really want to use the hack from the second article, but give the first article a skim because the second one builds on it.
