Just now learning C++ - I'm a very hands on learner https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20475#p20475 Sat, 27 Mar 2010 21:00:06 CDT SWR FUSS nobody@example.com (Keirath) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20473#p20473 Make sure you use new and delete [i]before[/i] you add constructors and/or destructors. The reason is that new will cause a constructor to be called, but malloc() and similar C functions will not. The same goes for destructor. delete will call it, but free() will not. https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20473#p20473 Sat, 27 Mar 2010 17:38:31 CDT SWR FUSS nobody@example.com (Caius) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20465#p20465 Ah perfect, that's what i needed to know. I've worked std::list into descriptor_data, time to write the constructors and destructor, and make everything new and delete. https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20465#p20465 Sat, 27 Mar 2010 08:43:39 CDT SWR FUSS nobody@example.com (Keirath) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20462#p20462 You can add any member functions to a struct, including constructors and a destructor. The [i]only[/i] difference between a class and a struct is that in a class all the members are private by default while in a struct all members are public by default. https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20462#p20462 Fri, 26 Mar 2010 21:57:10 CDT SWR FUSS nobody@example.com (Caius) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20460#p20460 Blah, bump I know, but I've been working on this a bit lately. Can I drop a constructor and a destructor right into a struct? Or do I need to convert the struct to a class? https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20460#p20460 Fri, 26 Mar 2010 13:39:31 CDT SWR FUSS nobody@example.com (Keirath) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20142#p20142 [quote=Andril]There's nothing to stop you from accidentally calling something like "Socket mySock = new Socket;" right now, other than knowing in your head not to do it. That would probably also lead to Bad Things(tm) based on my, admittedly limited, knowledge because I didn't see anything to initialize stuff except inside the constructor you have that takes an int. [/quote] It would be "bad" but not really as bad. Consider what would happen if you have a Socket object that you pass [i]as a https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20142#p20142 Sun, 14 Feb 2010 20:40:06 CST SWR FUSS nobody@example.com (David Haley) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20141#p20141 I understand about the copy constructor. I can just see all sorts of fun stuff happening if you accidentally give something a copy of another Socket object. :) And you have a constructor that takes an int to initialize the m_Control member and set up the net stuff and I totally understand why that's public and not private. I was referring specifically to the default Socket::Socket() constructor that [b]doesn't[/b] take any arguments.

But if you look at the code, the copy constructor is defined, but never implemented. It's defined and private so that I get an error on compile if something is trying to call it. Because the way I've done the work so far, copying a Socket would lead to Bad Things(tm). https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20140#p20140 Sun, 14 Feb 2010 11:30:09 CST SWR FUSS nobody@example.com (InfiniteAxis) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20139#p20139 [quote=Andril]Was just looking over your Socket class stuff and I noticed that you don't have the default constructor, Socket::Socket(), tucked away in the class as private like you do the copy constructor and the one for taking another instance of a Socket as a reference. Was kind of curious as to why not. [/quote] He probably wants to allow everybody to construct Sockets, but wants to prevent people from copying them. This is a generally good thing because it would be kind of weird to have se https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20139#p20139 Sat, 13 Feb 2010 21:49:08 CST SWR FUSS nobody@example.com (David Haley) https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20133#p20133 One thing I've noticed for myself is that another problem with trying to convert stuff from a struct to a class is just trying to figure out what should go into it as a member of the class, especially with functions. For instance with characters and object usage, when a character gets or losses an object, should the class for characters do something to drop the object, like ch->drop( obj ) where drop( &obj ) is a function in the character class that handles all the movement stuff, or should i https://smaugmuds.afkmods.com/topic/gameloop-4320/&p=20133#p20133 Sat, 13 Feb 2010 12:21:29 CST SWR FUSS nobody@example.com (Andril)
