01:10:00raptorgood evening


01:12:42raptorWatusimoto: what do you make of this crash report from sky_lark?:  http://pastie.org/pastes/9639143/text


01:15:40Nothing_Much has joined


01:17:08Watusimotohmmmm


01:17:14Watusimotocould ship somehow be null?


01:17:27raptorthat's what it looks like...


01:17:29raptorbut...


01:17:32Watusimotoor one of the ship's move states?


01:18:18raptorcan MoveStates ever be null?


01:19:20raptorit looks like it's created on the MoveObject at construction (if that's what declaring the struct in the header does), so it would be on the Ship object


01:30:23Watusimotoyes, I agree... moveStates can never be NULL


01:30:35Watusimotoso ship must be NULL... but... ???


01:30:47raptorso something happened to Ship...  in the middle of evaluating a movestate


01:31:32raptorfindDeployPoint uses:  const Ship *ship


01:34:06raptormaybe we need to use smart pointers...


01:35:22raptorthat 'const' isn't doing something tricky is it?


01:36:05raptorhmm...  too many layers for changing it to a smart pointer without a lot of refactoring


01:36:51Watusimotowell, it's all in the middle of a render loop


01:37:09WatusimotorenderGameNormal has this:


01:37:19WatusimotoShip *ship = getGame()->getLocalPlayerShip();


01:37:19Watusimotoif(!ship)     // If we don't know where the ship is, we can't render in this mode


01:37:19Watusimotoreturn;


01:37:30WatusimotoI doubt ship is getting set to null after that


01:37:49raptorwait wait


01:37:55Watusimotoso maybe ship pointer is coming from a different source later on that is in an inconsistent state


01:37:55raptorthat check is *not* in 019c


01:38:06raptormaybe that's the problem right there


01:38:09Watusimotono?


01:38:15Watusimotoit's been around forever


01:38:17raptornope, no check in renderNormal


01:38:51Watusimotohttp://hastebin.com/oreserezik.txt


01:38:55Watusimotonot like this?


01:39:22raptorthose pastie names always get me to read them twice


01:39:29Watusimotoha


01:39:36raptornope, not like that


01:39:39Watusimotothey have a good name generator


01:39:47raptori will add that, then, and hope for the best


01:40:21Watusimotomaybe the ship got killed while engineering


01:40:30raptorhuh - you added that here:  https://code.google.com/p/bitfighter/source/detail?r=b9b383471a72


01:40:43raptorthat was before 019c


01:41:13raptorbut not in 019c...


01:41:14raptoroh


01:41:16raptoroh right


01:41:28raptoryou were already doing *lots* of refactoring when I started the 019c branch


01:41:30Watusimotohmmm.... no recollection of that at all


01:41:45Watusimotothere must have been a reason


01:41:53Watusimotobut that might fix it


01:42:09raptoryes, I will do that


01:42:16raptorthanks!


01:46:03Watusimotook, I'm heading to bed... time to pay the piper for last night


01:46:11raptornight!

13:52:25fordcarsraptor: in Bitfighter, when drawing ships, does it rotate the Context?

14:00:53Invisible Quit (Client Quit)


14:06:08fordcarsOh never mind


14:06:17fordcarsI got it


14:16:27raptorfordcars: hi


14:16:34fordcarsHi


14:16:38raptorI, uh...  don't remember, but i doubt it


14:16:51fordcarsAre you good at math?


14:17:00raptoronce upon a time, yes


14:17:09fordcarsI am trying to draw a triangle with a certain angle to draw ships in the web app


14:17:11fordcarsHaha :P


14:17:31raptoroh


14:17:32fordcarsI don't want to translate the context since it would be a hassle


14:17:36fordcars*rotate


14:17:47fordcarsI already scale and translate the context


14:17:56raptori wrote some lua functions that do rotation like that for bobdaduck once


14:18:03raptoris this in c++?


14:18:06fordcarsIn js


14:18:08fordcars:)


14:18:15raptoroh boy


14:19:02fordcarsI wish I could just get three points and draw those


14:19:09raptorjust make 3 points


14:19:37raptori think the ships use a static triangle and jsut rotate it based on the angle it's facing


14:19:56fordcarsI checked out the code, all it does is draw the ships coords


14:20:07fordcarsSo I guess that's it


14:20:11fordcars*draw ship points


14:20:26fordcarsship->getPoitns or something


14:22:02fordcarsrenderVertexArray(shipShapeInfo->innerHullPieces[i].points


14:22:38raptoroh yeah, i forgot I abstracted that...


14:23:09raptordo it does a glRotate call first


14:23:16fordcars:(


14:23:17raptorthen just draws the triangle


14:23:30fordcarsOk


14:23:30raptorbut you probably don't have an API like that in JS


14:24:01fordcarsYes, but I already translated and scaled to fit the level, so I would need to translate to the ship's pos, and draw with scaling and blah


14:24:23fordcarsThere is an api for that though


14:24:40fordcarscontext.rotate()/context.transform()


14:24:51fordcarsIn html5

21:34:57raptorI'm not sure it's possible to implement sky_lark's /map change requests without a major refactor and possible protocol change


21:35:03raptormaybe i can get 2 of them..
