quote from a zeta player 3 miliseconds before i left the map; "piss!"

doesent matter now. the npc spawner mod actually works on this map if you download the background npc's support
Isoternal 19 Nov, 2022 @ 9:17am 
this map doesent work with the global npc spawner mod (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2816773479)

i wish there was a map without that void, like when i play with nextbots, all of them fall into the abyss and get stuck

WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little girl called Clarissa, she was ten-years-old and she lived in a mental hospital, because she killed her mom and her dad. She got so bad she went to kill all the staff in the hospital so the More- government decided that best idea was to get rid of her so they set up a special room to kill her, as humane as possible but it went wrong the machine they were using went wrong. And she sat there in agony for hours until she died. Now every week on the day of her death she returns to the person that reads this letter, on a monday night at 12:00a.m. She creeps into your room and kills you slowly, by cutting you and watching you bleed to death. Now send this to ten other profiles on this one site, and she will haunt someone else who doesn't. This isn't fake. apparently, if u copy and paste this to ten comments in the next ten minutes u will have the best of your

Props for the optimization on this map, i was able to have some huge npc battles with just slight dips in performance.
OnTheMatter  [author] 1 Apr, 2021 @ 1:51pm 
While lighting was only improved a little bit, performance/optimization has had a much more drastic upgrade. A few hint brush faces can seriously make a world of difference. The update will be out soon.

@Flightles101 The teleportation seems to be working fine on the Chromium branch, but I have admittedly noticed oddities with teleportation on another new map I've been working on as well. If it's a problem with the normal branch of the game then it'll likely be fixed soon, since things seem to be going well on Chromium. It very well could be some rogue addon as well, perhaps itself broken by the update. I'll still go in and spruce up the map a bit with an update, since it shouldn't take long to do. There's a room outside of the map which has a button to turn off the teleportation, maybe it got turned off somehow (by a player, addon, or anything else).
OnTheMatter  [author] 1 Apr, 2021 @ 11:09am 
@Flightles101 Thanks for letting me know, I'll take a look into it. While I'm at it I'll look into baking the map with better lighting as well, and maybe optimizing it better, since the compile time is pretty short. :steamthumbsup:

I think the map teleportation thing broke bc of the most recent Gmod update, because I no longer get warped to the top of the map anymore when I fall to the bottom
OnTheMatter  [author] 6 Mar, 2021 @ 1:30pm 
@Foff That's a good idea, I've always overlooked rain. Since this has been out for a while I'll leave it as it is, but I'll keep it in mind for future maps.
Foff 4 Mar, 2021 @ 3:32pm 
judging from the screenshots it looks like the map would benefit from some rain (if that's not already in place)

@Castle I felt it was worth having one of these steep slopes, as there were a lot of areas they could be created. At least it can work fairly well as an escape route of sorts.
Castle 31 Jan, 2021 @ 2:42am 
One of the ramps is too steep and you can't climb it.
OnTheMatter  [author] 18 Jan, 2021 @ 8:10am 
@Ladon If you're talking about Background NPCs, there is a link to the addon which adds support for it to all of my maps at the bottom of the description, including this and gm_construct_bay.

If you're talking about a spawner built into the map, there are addons which can set this up for any map, such as ZINV and NPC Tools, and I believe there is even an Attack Point addon as well, those should work fine on this map. I just prefer to leave the map as an open-slate, auto NPC spawn seems like a lot of effort for something made trivial by the existence of more-adaptable and modifiable tools which accomplish the same thing, with the possibility to be of an astronomically higher degree of quality. Just my thoughts, as I've had other people mention that before.

By the way, thanks to everyone for the support, I appreciate it. This was a map I really enjoyed making, it was a fun one to put together. I plan to work on a new map with a similar concept as this soon, I've been craving it.

With auto NPC spawn on this map, this would be 10/10

@buckministerfullerene There was a prop hunt or ttt map I remember a while back which had the same mechanic set at night, but it was very small. I'm sure it is still on here, that's the only other one I've seen.

Update coming in a few minutes. Contains pathing for Combine Gunships/Helicopters/Dropships, an improved navmesh, and a secret room outside of the map which has a button to toggle the teleport pit. I hope you all enjoy!
