2005-10-29Applied my own patch #1341495, in an attempt to fix alignment issuesTorbjörn Andersson
reported by Crilith. To elaborate a bit, the engine no longer accesses resource data through packed structs. Instead it uses memory streams and the READ/WRITE functions. If data is mainly read, not written, I have replaced the old struct with a new one with a read() function to read the whole thing from memory into the struct's variables, and a write() function to dump the struct's variables to memory. In fact, most of these write() functions remain unused. If data is both read and written, I have replaced the struct with a class with individual get/set functions to replace the old variables. This manipulates memory directly. Since I'm fairly sure that these structs are frequently stored as local variables for a script, all script variables (both local and global) are stored as little-endian and accessed through the READ/WRITE functions, rather than being treated as arrays of 32-bit integers. On a positive note, the functions for doing endian conversion of resources and save games have been removed, and some general cleanups have been made to assist in the rewrite. Initial reports indicate that this patch indeed fixes alignment issues, and that I have not - surprisingly - broken the game on big-endian platforms. At least not in any immediately obvious way. And there's still plenty of time to fix regressions before 0.9.0, too. svn-id: r19366

2005-02-19This is the second part of the BS2 restructuring. There are two newTorbjörn Andersson
classes: Screen and Mouse. Screen handles most of the drawing, except the mouse cursor and in-game menus. The old Graphics class is no more. I've also fixed some "reverse stereo" regressions from the first part of the restructuring. I'm not sure what the next step will be, but hopefully it will be smaller than this one was. svn-id: r16812
2005-01-28Began what I hope is the final major restructuring of the BS2 engine.Torbjörn Andersson
In this first step, I have moved all opcode functions into functions.cpp, instead of having them scattered all over the place. To get things to compile again, I had to rewrite the overly complicated sound effects handling. It's much simpler now. The next step will be to move any non-trivial code out of the opcode functions and into the appropriate object. This, I hope, will make it easier to create well-separated objects, instead of the current mess. I also want to tear down the artificial boundary between the main directory and the "driver" directory. We already have a cross-platform layer; there's no need to have yet another one. (Actually, the rewriting of the sound effects code took one first step in this direction.) At the final stage, I'd like to get rid of the "drivers" directory completely, but I'll probably need some help with that if I want to preserve the CVS history of the code. Things will probably be a bit bumpy along the way, but I seem to have reached a point of relative stability again, which is why I'm commiting this now. svn-id: r16668

svn-id: r15297
2004-09-08Fixed evil regression #2. Restarting the game, or using the "start" debugTorbjörn Andersson
command, would close the global script variables and player object resources, without reopening them again. This made them fair game for the resource expiration mechanism. The player object is probably referenced often enough to stay alive, but the variables died on me pretty quickly, causing ScummVM to crash. I've also added a "reslist" debug command to make this sort of things easier to spot. By default it only lists resources with refCount > 0. Use "reslist 0" to see all the cached resources as well. svn-id: r14958

2004-03-17Use the same syntax for accessing script variables as BS1 does, i.e. nowTorbjörn Andersson
it's Logic::_scriptVars[ID] instead of just ID. Apart from looking cool, it makes it much easier to tell the difference between variables and constants when looking at the code. Of course, this sort of sweeping changes is jolly good for introducing truly weird regressions, which is why I waited until after 0.6.0. svn-id: r13331

2004-01-05Fixed some debugging messages so they refer to the correct function.Torbjörn Andersson

2003-12-28Hopefully the last big renaming. Now the datatypes have names likeTorbjörn Andersson
"StandardHeader" instead of "_standardHeader". svn-id: r11997
2003-11-27Mostly whitespace changes, but also a few modifications to the stillTorbjörn Andersson
experimental resource dumping code. svn-id: r11382
2003-11-23Added experimental (i.e. not tested) resource dumping code.Torbjörn Andersson
Added tentative workaround for the bug (a script bug, I think) that causes the game to hang when examining the lift at the top of the pyramid. And, of course, some misc. cleanup. svn-id: r11359
2003-11-19Eliminated some more references to g_sword2. I think the only thing thatTorbjörn Andersson
still uses it are the engine's global variables which, on the other hand, are used *everywhere*. I'll have to think some more about those. I guess I should take a closer look at how the other engines handle them. (That goes for a lot of things by the way.) svn-id: r11349
2003-11-16More cleanup. I've eliminated all the temporary global variables I've addedTorbjörn Andersson
over the past few weeks, except for g_sword2. (Of course, this doesn't necessarily make the code any prettier, but we can work on that later.) svn-id: r11309
2003-11-15Mostly cleanup. Also prevented what would probably have been an infiniteTorbjörn Andersson
loop if ScummVM failed to find a file in the demo. (Now it should error out instead, which is marginally preferable.) svn-id: r11298
2003-11-11Moved low-level keyboard and mouse handling to a new Input class, andTorbjörn Andersson
renamed the Display class Graphics for no better reason than me liking the phrase "sound and graphics" better than "sound and display". svn-id: r11258
2003-11-08Removed some now redundant header files.Torbjörn Andersson
svn-id: r11209
2003-11-08Moved more stuff into classes, changed some static allocation to dynamic,Torbjörn Andersson
and removed some of the references to global variables. At this point I believe everything in the main game engine has been moved into classes - not necessarily the correct ones, but still... However, there is some stuff in the driver directory that need to be taken care of as well. svn-id: r11207
2003-11-04Create g_logic dynamically. More moving of stuff into classes.Torbjörn Andersson
svn-id: r11129
2003-11-03The resource and memory managers are now created dynamically.Torbjörn Andersson
Renamed the resource manager's open/close methods openResource() and closeResource() to avoid confusion. (It was I who originally shortened their names to open() and close(), but I've changed my mind now.) Moved more stuff into Sword2Engine. svn-id: r11088

2003-10-26Enable the debug console. Actually, what I've done is to adapt the debugTorbjörn Andersson
console from the SCUMM engine. I decided that would be easier than to clean up the original console code. Unfortunately there's a bunch of code that I just copied - a pretty lousy form of code-reusal. It'd be nice if the console could be made part of the Engine class, or something like that. Most of the debug commands seem to be working. Some aren't relevant for ScummVM, and some are a bit obscure so I'm not quite sure what they're supposed to be doing. svn-id: r10978
2003-10-22Moved a few remaining pieces of the script interpreter into the Logic classTorbjörn Andersson

svn-id: r10885
2003-10-15Dumped most of the remaining "driver" code into a new "Display" class. ThisTorbjörn Andersson
touches a lot of the code, of course, and adds yet another global variable (temporarily, I hope), but everything still seems to work. Knock on wood. svn-id: r10806
2003-10-12Moved the "router" code into a new Router class. I'm hoping this isTorbjörn Andersson
analogous to the SkyAutoRoute class. svn-id: r10754
2003-10-04Changed to use #include "bs2/..." and removed the inclusion of standard CTorbjörn Andersson
headers. Most (all?) of the ones we need should probably come from stdafx.h instead. svn-id: r10588

2003-09-27More cleanup, and I've replaced most - not quite all - of BS2's debugTorbjörn Andersson
message functions with our own. We still need to go through them and assign sensible debug levels to them. svn-id: r10422
2003-09-26Some more reformatting / cleanup, and removal of comments that did nothingTorbjörn Andersson
but say who added what when. (No disrespect intended, but this information means very little to us.) svn-id: r10413
2003-09-23Changed the keyboard handling to store "keyboard events", rather than justTorbjörn Andersson
characters. Hopefully this will make things work smoother on the Mac, but I have no way of testing that. svn-id: r10376
