13:14:43 raptor sam686: do you happen to have those old forum attachments laying around somewhere still?  The ones you had a backup copy of that let us restore some from the latest server loss
13:15:01 raptor maybe they're on the bitfighter server, but i can't find them

22:32:28 Watusimoto has joined
22:35:25 Watusimoto hi
22:38:43 raptor hi
22:39:46 Watusimoto I found a crash in the editor I don't know how to fix (yet)
22:40:10 Watusimoto inside idEntryCallback(), we do this:
22:40:10 Watusimoto ClientGame *clientGame = static_cast<ClientGame *>(object->getGame());
22:40:11 Watusimoto UIManager *uiManager = clientGame->getUIManager();
22:40:23 Watusimoto but objects don't really belong to a game in the editor any more
22:40:39 Watusimoto so I need to figure out a static method to get the UI manager
22:41:48 raptor Settings.get()->
22:42:05 Watusimoto btw, I think my brain is broken, at least as far as Lua is concerned
22:42:11 raptor oh goodie!
22:42:18 raptor my turn then?  :)
22:42:32 Watusimoto yes
22:42:34 Watusimoto I think so
22:42:44 Watusimoto I left the function with my latest attempt commented out
22:42:54 Watusimoto look in my last night's checkin
22:43:03 Watusimoto I updated all the comments, documentation, and tests
22:43:08 raptor I wasn't sure where you were, but I was going to try and test C API clearing of a table, then try calling our table.clear() Lua method from the C API.  then comparing
22:43:22 raptor there was a checkin?
22:43:34 Watusimoto I spent like 2 hours trying to make it work; I couldn;t make either of those approaches work
22:43:37 Watusimoto let me see
22:43:55 raptor doesn't look like you pushed anything
22:44:03 BFLogBot Commit: 2acdbc1ee7 | Author: watusimoto | Message: Update with placeholder for lua_clearTable(), which still needs to be written; tests should pass when that function works
22:44:10 raptor and are you working on 020 or 019 branch?
22:44:11 Watusimoto I think I did :-)
22:44:12 raptor ah ha
22:44:14 raptor heh
22:44:16 raptor thanks
22:44:40 Watusimoto I hope this is the 020 branch...
22:45:39 raptor yes
22:45:41 raptor good
22:45:58 Watusimoto I'm thinking about adding a static method to get the editorUI
22:46:13 raptor i thought you could already get any UI statically
22:46:18 Watusimoto I can imagine having two gameUIs going at once, but not two editorUIs
22:46:32 Watusimoto i don't think so
22:46:47 Watusimoto because we've always imagined having multiple game clients running at once
22:46:54 Watusimoto so there would be multiple gameUIs
22:47:03 raptor why would you need a static call again?
22:47:17 Watusimoto idEntryCallback() is a static method
22:47:20 raptor ahhh
22:47:24 raptor so make it not static
22:47:35 Watusimoto it references the code above only on its way to getting the editorUI
22:47:46 Watusimoto can you pass a non-static method as a callback?
22:47:56 Watusimoto I think you can, but I remember it causing heaps o' trouble
22:47:57 raptor not really sure, honestly - it was a wild guess
22:54:10 Watusimoto we only use this callback in two places... maybe I could pass a UI along with the other stuff
22:54:24 Watusimoto though that seems kind of icky
22:55:23 raptor the more I read about 'static' in c++, the more I find it icky...
22:55:37 Watusimoto this is crazy
22:56:21 Watusimoto we use an object to get a client game, to get a ui manager, to get the editor UI, to do a search for objects to make sure there are no duplicate ids
22:56:33 raptor ah yes... i think callbacks need to be static functions
22:56:41 raptor because otherwise you need to pass an object
23:00:26 raptor i'd say pass in a pointer
23:00:36 raptor we pass in ClientGame* to a lot of callbacks
23:01:46 amgine123 if yu ever need testing call me!
23:42:32 raptor lua stack for dummies
23:48:23 raptor Watusimoto: i'm not sure I can use the C API to clear the table and to leave it on the stack...
23:48:44 Watusimoto no?
23:48:52 raptor calling a method with an element on the stack pops that element from the stack
23:49:06 Watusimoto you mean calling a lua function?
23:49:12 raptor yes
23:49:23 raptor so calling table.clear(filltable)
23:49:28 Watusimoto true; I figured the function you'd call would push the table back on the stack
23:49:33 raptor would pop filltable from the stack
23:49:39 Watusimoto you can see what I was trying to do
23:49:42 raptor oh so it would return the table again
23:49:45 Watusimoto and that was my solution
23:49:51 raptor hmmm
23:50:00 Watusimoto because you are right
23:50:28 Watusimoto I figure a push is cheap
23:50:38 raptor yeah, compared to a copy
23:50:42 raptor ok...  i have an idea
23:50:49 raptor let me see if this works..
23:50:52 Watusimoto but I couldn't figure out how to do an anonymous function that did clear then push
23:51:21 raptor i just added 'return tab' to our table.clear() method
23:56:03 Watusimoto ha, ok
23:56:08 Watusimoto is that weird?
23:56:23 raptor it seems really weird but the more i think about it.. it is elegant
23:58:06 Watusimoto it allows you to make sure the table is really clear
23:58:21 Watusimoto table.clear().clear().clear().clear()
23:58:41 Watusimoto oh wait, I blew that one
23:58:46 raptor hahaha
23:58:56 Watusimoto table.clear(table.clear(table.clear(filltable))))
23:59:01 raptor ok, tell me if looks off before I run it:  http://pastie.org/pastes/9779395/text
23:59:08 raptor *if this
23:59:33 Watusimoto that made my brain melt
23:59:39 Watusimoto I have a lua allergy, I think
23:59:43 raptor ok, i'll just run it :)
23:59:50 Watusimoto run the tests... you'll find out!
