02:13.28Packmanwould you leak memory for using "bz_getPlayerByIndex(playerID)->spawned" without creating a bz_PlayerRecord?

02:27.22BulletCatcherPackman: Are you planning to modify bz_getPlayerByIndex() to *not* create the bz_PlayerRecord?
02:29.26PackmanI'm not modifying anything, but yes I am trying to avoid creating the player record
02:29.40Packmanand deleting it at all
02:30.11BulletCatcherA call to bz_getPlayerByIndex() will create a new bz_PlayerRecord instance.
02:30.35BulletCatcherc++ garbage collection should recover the space when you no longer have a reference to it.
02:31.22trepanc++ GC?
02:31.56BulletCatcherIs that a null function?
02:32.00trepanwhat reference?
02:32.50BulletCatcherbz_getPlayerByIndex() creates a new bz_PlayerRecord, and returns a pointer to it.
02:33.17trepanc++ does no GC magic on pointers
02:33.27BulletCatcherThen one must call free() to release the space.
02:33.50Packmanso it is necessary to create the record and delete it?
02:34.14trepanbz_getPlayerByIndex() / bz_freePlayerRecord()
02:34.33trepanit's awkward, but it's what you have to work with

19:04.44blast007shrugs
19:04.51blast007I'm not familiar with that code
19:04.52Packmanlol
19:04.58blast007dt is difference in time
19:05.24Packmanmaybe. bz wiki says dt = delay time :/
19:05.32blast007wiki is wrong
19:06.17blast007it probably shouldn't even be exposed
19:08.07blast007bzfs seems to just put a 0 there for dt
19:08.33blast007so it might not even be all that useful of a parameter ;)

19:14.06blast007Packman: the one thing it might do is let you have world weapons that expire sooner
19:14.18blast007say, if you set it to 10, it might expire 10 seconds earlier
19:14.30blast007you'd have to test that though :)
19:15.47Packmanthat sounds very strange :P
19:17.12blast007well, dt is used for calculating motion and distance
19:18.28blast007if dt is 5 seconds, and we have the position, forward vector, and velocity of an object from before that 5 seconds of time, we can calculate where that object is (or might be) now
19:18.55blast0075 seconds is an extreme example though, as the dt in the game is usually much less
19:19.35blast007if you're running the game at 60FPS the dt might be something like 0.01666667
19:20.13blast007(iirc, we have some code in 2.0.x or 2.99.x that ensures dt is large enough before running the simulation code, otherwise high FPS caused issues)
19:20.29blast007floating point issues from such a small dt
19:20.55Packmanyeah i think 1000+ fps acts the same as 1000
19:21.08Packmanfor motion at least
19:21.58blast007well, at that point yeah :P
19:22.06blast007more than 200 FPS is a problem
19:23.08Packmanin 2.0.x the effect of gravity and jumping vary with fps
19:24.01blast007yup
19:24.22blast0072.99.x might be better, because I think it will segment the simulation if the dt is too large
19:24.35blast007but still not gonna be perfect
19:25.15Packmanmaybe a bit of calculus will help; always useful for getting things perfect ;)
19:25.38blast007or a bit of rewriting the game from scratch with proper code ;)
19:25.52blast007some games have their simulation run at a constant "FPS"
19:26.03Packmanisn't yassen trying to do that? :P
19:26.26blast007so, say, they might always run their simulation code at 60FPS even if their graphics runs at 25 or 250 FPS
19:26.46blast007then they don't have to mess around with FPS causing simluation differences
19:27.05blast007and their server is also likely authoritative
19:27.21blast007so if they get out of sync, the server will correct it for them ;)
19:27.31Packmanis 3.0 release currently "expected", or on hold?
19:27.39blast007dead
19:27.48blast007It's dead, Jim.
19:27.53Packmanlol
19:28.01joevanodoor nail dead
19:28.21Packmanis 2.99 usable?
19:28.31blast007depends on your definition of usable
19:28.32alezakosonly 2 public servers
19:28.39blast007it's not "good enough" for a release
19:28.47blast007there are some critical bugs in yet that affect gameplay
19:29.01blast007but hey, at least everyone gets the same random world now!
19:29.07Packman:D
19:29.25blast007(there was a bug for a while that would regenerate the random maps when a certain player rejoined)
19:29.40Packmanso the devs are not working on anything? Will there even be 2.0 releases or just NOTHING
19:29.46blast007probably just nothing
19:29.57alezakossomeone said there is time, but no wil
19:30.06blast007there's always time
19:30.09blast007time is unending
19:30.18blast007well, at least until December 21st, 2012
19:30.24Packmangiven infinite time and no motivation, 3.0 will thus one day be complete :P
19:30.33blast007offer not valid in CA
19:30.48blast007some restrictions apply
19:31.42Packmanare there discussions of whether all bzflag servers will close? E.g. list server taken down, everythign else
19:31.56blast007I don't see that happening any time soon

20:40.05Packmanit sometimes happens when trying to spawn after a pause or death
