By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

It can be played with either + a mouse or a joystick. + + SDL + --- + "Super Tux" was programed using the "Simple Direct Media" layer + libraries by Sam Lantinga. This means that the game can + theoretically run under any environment that the SDL libraries support. + + (As of this program's release, this includes: Linux X11/DGA, + Win32 WinDIB/DirectX, BeOS BWindow, and Solaris X11, as well + as unofficually supported: Linux SVGAlib, IRIX 6.x X11, + FreeBSD 3.x X11, and MacOS.) + + The Simple DirectMedia Layer is required to compile this game. + + You can download the SDL libraries from: + http://www.libsdl.org/ + + SDL_image + --------- + SDL_image is also required. (It is used to load the PNG format images + that come with Super Tux!) + + SDL_mixer + --------- + Sound and music are available, but are not required (see below). + You will need the "SDL_mixer" library compiled and installed if + you want sound. + + +INSTALLING UNDER LINUX/UNIX +--------------------------- + ----------------------------------------------------------------- + Note: Read this entire section before you start issuing commands! + ----------------------------------------------------------------- + + First make sure SDL, SDL_image and, optionally, SDL_mixer, are + installed on your system. + + The "Makefile" that comes with "Super Tux" assumes a number + of defaults about your system. You can edit their values in + the "Makefile" itself, or specify their values when you run + the "make" command (ie, "make VARIABLE=value"). + + The things you will wish to edit are: + + SDL_PREFIX=/usr/local + + This defines the base location where the "include/SDL/" + and "lib/SDL/" directories will be found. (They contain + the C header files and compiled object files for SDL, + respectively.) + + + DATA_PREFIX=$(PWD)/data/ + + This defines where "Super Tux"'s "data/" directory is + to be found. The default assumes that you wish to leave + it where it is right now ("$(PWD)" expands to become the + current direcotry. + + This variable is useful if you plan on moving the "data/" + directory elsewhere, say a globally-accessible + "/usr/local/games/supertux-data/". + + JOY=YES + + This causes "Super Tux" to be compiled with joystick + support. If you don't have a version of SDL that supports + joystick, or just don't want joystick support, set this to "NO". + + + To compile the game, type the command: + + make [ with whatever variable changes you want, if any ] + + If you decided that you wanted the data somewhere else, make sure + to move it there. If you wanted it to be accessible to others + (ie, you're an administrator installing a new game for your users), + make sure to set the permissions for the files! (You'll also want + to move the "supertux" binary to somewhere globally accessible, + and set its permissions, as well, of course!) + + Note: If you do not have the SDL_mixer library, or wish to not + compile sound support into the game, you can compile it like this: + + make nosound [ with whatever variable changes you want, if any ] + + If you wish to return the directory to its distribution state, + (remove the ".o" object files, and the "supertux" executable program + file), you can run: + + make clean + + +ICON FILE +--------- + A 32x32, XPM-format icon file (using the standard 23-color "cmap.xpm" + color palette) is available if you wish to use an icon for this game. + + The file is "supertux-icon.xpm", and installed in Super Tux's + "data/images/" directory. + + +The End! diff --git a/Makefile b/Makefile new file mode 100644 index 000000000..05dd31942 --- /dev/null +++ b/Makefile @@ -0,0 +1,101 @@ +# Makefile for supertux + +# by Bill Kendrick +# bill@newbreedsoftware.com +# http://www.newbreedsoftware.com/ + +# Version 0.0.0 + +# April 11, 2000 - December 26, 2000 + + +# User-definable stuff: + +DATA_PREFIX=$(PWD)/data +JOY=YES + + +# Defaults for Linux: + +TARGET=supertux +TARGET_DEF=LINUX + + +CFLAGS=-Wall -O2 $(SDL_CFLAGS) -DDATA_PREFIX=\"$(DATA_PREFIX)\" \ + -D$(NOSOUNDFLAG) -D$(TARGET_DEF) -DJOY_$(JOY) + + +# Other definitions: + +SDL_MIXER=-lSDL_mixer +SDL_IMAGE=-lSDL_image +NOSOUNDFLAG=__SOUND +SDL_LIB=$(SDL_LDFLAGS) $(SDL_MIXER) $(SDL_IMAGE) +SDL_CFLAGS := $(shell sdl-config --cflags) +SDL_LDFLAGS := $(shell sdl-config --libs) +installbin = install -g root -o root -m 755 +installdat = install -g root -o root -m 644 + + +OBJECTS=obj/supertux.o obj/setup.o obj/intro.o obj/title.o obj/gameloop.o \ + obj/screen.o obj/sound.o + +# Make commands: + +all: $(TARGET) + +#install: $(TARGET) +# -$(installdat) data $(DESTDIR)/usr/share/games/$(TARGET)/data +# -$(installbin) $(TARGET) $(DESTDIR)/usr/games/ + + +nosound: + make supertux SDL_MIXER= NOSOUNDFLAG=NOSOUND + +win32: + make TARGET_DEF=WIN32 TARGET=supertux.exe \ + DATA_PREFIX=data + cp /usr/local/cross-tools/i386-mingw32/lib/SDL*.dll . + chmod 644 SDL*.dll + +clean: + -rm supertux supertux.exe + -rm obj/*.o + -rm SDL*.dll + + +# Main executable: + +$(TARGET): $(OBJECTS) + $(CC) $(CFLAGS) $(OBJECTS) -o $(TARGET) $(SDL_LIB) + + +# Objects: + +obj/supertux.o: src/supertux.c src/defines.h src/globals.h \ + src/setup.h src/intro.h src/title.h src/gameloop.h \ + src/screen.h src/sound.h + $(CC) $(CFLAGS) src/supertux.c -c -o obj/supertux.o + +obj/setup.o: src/setup.c src/setup.h \ + src/defines.h src/globals.h src/screen.h + $(CC) $(CFLAGS) src/setup.c -c -o obj/setup.o + +obj/intro.o: src/intro.c src/intro.h \ + src/defines.h src/globals.h src/screen.h + $(CC) $(CFLAGS) src/intro.c -c -o obj/intro.o + +obj/title.o: src/title.c src/title.h \ + src/defines.h src/globals.h src/screen.h + $(CC) $(CFLAGS) src/title.c -c -o obj/title.o + +obj/gameloop.o: src/gameloop.c src/gameloop.h \ + src/defines.h src/globals.h src/screen.h src/sound.h \ + src/setup.h + $(CC) $(CFLAGS) src/gameloop.c -c -o obj/gameloop.o + +obj/screen.o: src/screen.c src/defines.h src/globals.h src/screen.h + $(CC) $(CFLAGS) src/screen.c -c -o obj/screen.o + +obj/sound.o: src/sound.c src/defines.h src/globals.h src/sound.h + $(CC) $(CFLAGS) src/sound.c -c -o obj/sound.o diff --git a/README.txt b/README.txt new file mode 100644 index 000000000..ed4321b4e --- /dev/null +++ b/README.txt @@ -0,0 +1,181 @@ +README.txt for Super Tux + +by Bill Kendrick +bill@newbreedsoftware.com +http://www.newbreedsoftware.com/supertux/ + +Version 0.0.3 + +November 14, 2001 + + +NOTICE!
