Bugzilla – Bug 537
cyberdemon and other items spawn randomly in ctf
Last modified: 2009-12-30 17:07:19 CST
(01:32:48) denis: how does one reproduce the cyberdemon ctf bug (and why is it not in bugzilla)?
(01:45:24) Ralphis: i think a lot of those tests occured during the time the bug tracker had been down
(01:45:50) Ralphis: and how to reproduce it? play a game with a bunch of connections
(01:46:07) denis: cyberdemon appears serverside?
(01:47:06) Ralphis: more than cyberdemons
(01:47:14) Ralphis: but cyberdemon is the most consistent and always spawns at 0,0
(01:47:19) Ralphis: other items appear at other coordinates
(01:50:36) denis: interesting, is it difficult to reproduce?
(01:52:47) denis: i imagine it's not difficult to breakpoint it once the thing happens
(01:53:35) denis: any particular wad/map?
(01:54:23) Ralphis: we had it happen on the zdctf boom conversion, 2cctg-2 or something other
(01:54:44) Ralphis: if you get a game going you can reproduce it easily, it's going to happen eventually
(01:55:10) Ralphis: ghostlydeath ran a debugger when it happened but either he didn't find anything or, what I think might be more likely, didn't actually know what he was looking for
(01:55:24) Ralphis: cybs ALWAYS spawn at 0,0 though, other things spawn elsewhere
(01:55:33) Ralphis: sometimes only one cyb will spawn, sometimes about 500 will
(01:55:38) Ralphis: not at the same time
(01:55:44) Ralphis: and they actually "teleport" in, with the teleport sprite and all
(02:00:50) Ralphis: there were a few conditions we used which seemed to make it occur more frequently but who can be sure if they really did make it occur more frequently
(02:00:54) Ralphis: mostly ctf_manualreturn 1
also skill 5

Odactf1.wad map04 c/s, by the 2 boxes in the middle of the map, if you pick up a flag and score, sometimes you will get a dead body on a stake appear at 0,0 (which is next to one of the boxes)
it was on the coffeenet.org server I witnessed this, and it only happens if you score with the flag it seems

Scrub that, all you have to do is pick up the flag and watch out the window, but scoring doesn't make a difference
It also spawns like an item, with a flash and the item respawn sound
can't reproduce this locally
tried as blue and red player
CTF_CarryFlag and CTF_MoveFlags do look suspect, but that would only create clientside monsters
try: itemsrespawn 1

I made a vid a little while ago about it which shows the issue:

I was able to successfully reproduce this thanks to this description and the video. Just letting you guys know its not specific to Russell's system. Debian 5.01 here in case that info is needed.
Feel free to use my server to reproduce this bug, Ralph has the rcon but if you guys need any additional help just ask.
Nes committed a possible fix (it fixes the corpse-on-pike spawn), please test r1284
This bug has gone stale, I've tested and it works, if it occurs for anyone please respond in the next 10 days or I'm closing this
Marking fixed. If it comes up again create a new bug.
