-These are mostly bugs:
-
-Todo
-----
-H: high priority
-L: low priority
-
-[M] Enemies can get stuck when colliding.
-[M] When aborting a level, lives and score should remain the same as they
- were before. Solution: make more dependency between the game engine and worldmap
- or just backup those variables before starting a level.
-[M] When jumping into a brick and there is a powerup, it should change direction or not,
- depending where the collision was. It currently sucks.
-[M] Tux should fall while walking in tiles that have a space between.
-[L] time runs while being in in-game menu, at least a bit (jump, go to
- menu, wait a bit, leave menu, Tux will 'flip' to the ground,
- instead of fall, pause mode doesn't seem to have this problem, only
- menu)
-[L] Backscroll is really messed up right now :)
-[L] change lispreader to throw exceptions instead of simply assert() on
- syntax error
-[L] fadein/out for intro/extro would be nice
-[L] when bumping a special with 2 blocks at once, it won't change direction
-[L] tux get killed if he kicks a iceblock while at the same time
- bouncing on the roof
-[L] in the "Welcome to Antarctica" level, the blocks next to the first growup
- look like there are 2 blocks above each other when bumping against them as
- small tux...
-[L] Enemies should turn upside down after being hit by an kicked
- iceblock
-

-Stuff for past milestone1:
---------------------------
-Note that this list is far from complete, but lists some bugs that we don't want
-to touch before milestone1 at the moment.
-- You shouldn't be able to stand on invisible blocks, before you bumped them
-- bombs should explode directly when hit by another bomb or a mr.iceblock
-- we only have a global counter for multiple coin blocks. This should be handled
- per block.
-- We should reduced the width of tux collision rectangle so that he falls easier
- between 1 tile wide holes.
-- The enabled/disabled icon in the options shouldn't be a cross. Some people
- think the options are disabled because they're crossed. Better use a green
- check mark.
+This is a list of tasks and issues that might be worth to implement or
+fix. This list is however not an authorative list of things that must
+be done, its a collection of random things that pop up during
+development, therefore not everything in here might be well thought
+out or worth to implement. Use your brain before implementing anything
+on this list and always think about how useful a new feature would be
+in the context of the whole game or if a potential performance
+enhanchment, actually enhanchmes anything at all.
+Coding Standard Stuff
+=====================
+
+* make code clean: "-O2", "-g3",
+ "-ansi",
+ "-pedantic",
+ "-Wall",
+ "-Wextra",
+ "-Wnon-virtual-dtor",
+ "-Weffc++",
+ "-Wconversion",
+ "-Werror",
+ "-Wshadow",
+ "-Wcast-qual",
+ "-Winit-self", # only works with >= -O1
+ "-Wno-unused-parameter",
+
+* remove overuse of multi-inheritance
+
+* remove overuse of friend'ship
+
+* maybe mark interfaces as interfaces (ISerializable or SerializableInterface)
+
+* split files with multiple classes into multiple files with one class each
+
+* Decide what to do with magic constants of objects (static vs anonymous namespace vs lisp property)
+
+* check the code with Valgrind and profilers
+
+* use Vector in Physics for 'a' and 'v'
+
+* replace random generator with mersenne twister and/or move to external/ (maybe use boost's random stuff)
+
+* md5.hpp and random_generator.hpp could go to external/
+
+* write/finish scripts to automatically:
+
+ - make all includes relative to top level dir
+
+ - sort includes (.hpp file, then system includes, then other project files)
+
+ - include guards proper and of the form HEADER_SUPERTUX_${PATH_TO_FILE}_HPP
+
+TODO
+====
+
+* implement a system that allows to attach comments to specific regions in a level
+
+* implement a tool to "screenshot" a complete level
+
+* GameObject::RemoveListenerListEntry: Ughs, somebody trying to
+ implement a list class within in the GameObject?!
+
+* add --datadir DIR (data/) and --userdir DIR (~/.supertux/), allow multiple --datadir's
+
+* make gravity constant
+
+* rename Vector -> Vector2f
+
+* get rid of global SDL_Screen* screen variable
+
+* get rid of SCREEN_WIDTH/SCREEN_HEIGHT overuse, give them a proper name at least
+
+* resolution menu entry moves the wrong way around
+
+* having dictionary_manager in Lisp is extremely ugly
+
+* enforce proper naming of files to match their class (SomeClass -> some_class.?pp or so)
+
+* file naming is inconsistent: some times we use '_' to separate
+ words, sometimes we don't
+
+* collect all manager classes into globals.hpp
+
+* more moving directories around?
+
+addon/

+video/
+squirrel/
+ for generic squirrel code
+supertux/
+ worldmap/
+ trigger/
+ scripting/
+ for scripting wrapper code
+ badguy/
+ object/
+
+* implement PNG screenshot
+
+* having hitbox in Sprite is fugly
+
+* write decal object that doesn't have hitbox
+
+* implement surface and/or sprite scaling (MipMaps?)
+
+* add code that compares the last Log line with the current, if they
+ are the same reject them and just output something like:
+
+ * last line has been repeated X times
+
+* implement: http://standards.freedesktop.org/basedir-spec/basedir-spec-0.6.html
+
+* workaround for Ubuntu pulseaudio/OpenAL brokeness:
+
+$ cat ~/.alsoftrc
+drivers = oss
+
+* peaking up/down doesn't work properly
+
+* peaking left/right should make Tux look into that direction (up/down to, needs new sprites)
+
+* keep possible future SDL1.3 upgrade in mind (what has changed?)
+
+* cleanup scripting interface
+
+* replace cloud tiles with decals
+
+* option menu has text overlap in "aspect ratio"
+
+* jumping up from an enemy doesn't make a sound?
+
+* add support for automatic scrolling backgrounds
+
+* add direct reading of Vector2f to Reader/lisp
+
+* replace bell with 'reset block', that starts to glow once bumped
+ into (or something different)
+
+* refactor Camera code, break ugly long functions into pieces and such
+
+* allow fully custom magnification levels from command line (maybe GUI
+ to if there is a proper/easy way to let the user enter numbers)
+ (--magnification or -g WIDTHxHEIGHT:ASPECTX:ASPECTY@MAGNIFICATION)
+
+* use AnchorPoint in Background instead of Alignment
+
+* allow gradients to parallax scroll like Background (make it optional)
+
+* add multicolored gradients (see Windstille source code, which can deal with Gimp gradients)
+
+* fix alpha blending in the SDL renderer, currently all sprites (Tux,
+ etc.) appear transparent
+
+* position of statistics text on the worldmap doesn't scale properly with resolution it seems
+
+* gluBuild2DMipmaps leads to blurriness, maybe lack of magic offset
+ (0.375f, 0.375f, 0.0f) or something else
+
+* font system has blending artifacts at non-1x magnifications, need to
+ have an transparent pixel between letters
+
+* add a (border #t) flag to fonts, that allows to use fonts which have
+ a 1px transparent border around glyphs, which is needed to get rid
+ of blending artifacts in OpenGL
+
+* mouse cursor has blend artifact on high magnification
+
+* shadow font glyphs bleed into other glyphs
+
+* in DrawingRequest "void* request_data;" is only free'ed, but the
+ destructor never gets called
+
+* sprite/sprite.cpp: frame should never get out of range:
+
+ if((int)frame >= get_frames() || (int)frame < 0)
+ log_warning << "frame out of range: " << (int)frame << "/" << get_frames() << " at " << get_name() << "/" << get_action() << std::endl;
+
+* Surface::hflip() is used exactly once, should probally be part of the constructor
+\f
+Scenegraph and Physics Engine Restructuring
+===========================================
+
+* random idea to restructure engine stuff (might lead to nicer code
+ and easier scriptability (and a need to rewrite lots of stuff...):
+
+class SomeBadGuy : public PhysicsCallbackListener // or use boost::function
+{
+private:
+ PhysicsPtr box;
+ SpritePtr sprite;
+
+public:
+ SomeBadGuy(Engine& engine)
+ {
+ box = engine.physics().create_box(Rectf(0,0,32,32));
+ box->register_listener(this);
+ sprite = engine.graphics().create_and_add_sprite("Foobar");
+ }
+
+ void update(float delta)
+ {
+ // not much to do, as most stuff is done internally in the engine
+ if (dead)
+ {
+ sprite->replace_with("Foobar_dead");
+ }
+ else
+ {
+ sprite->hide();
+ sprite->set_pos(box->get_pos());
+ }
+ }
+
+ // no more draw(), done by the scene graph
+
+ void on_collision(CollisionData data)
+ {
+ // respond
+ }
+};
+
+Random Notes
+============
+
+* calculate the size of an background image that should fill the screen:
+
+ image_size = (1 - parallax_speed) * screen_size + level_size * parallax_speed
+
+def calc(parallax, screen, tiles):
+ return (1 - parallax) * screen + parallax * tiles * 32
+
+\f
+Supported Resolutions
+=====================
+
+SuperTux shall support resolutions from 640x480 to 1280x800 at a magnification of 1x.
+For resolutions higher, such as 2560x1600, upscaling will be used.
+For resolutions smaller, like 320x240 downscaling will be used.
+
+Higher resolution graphics for 2x maginification might be provided.
+Lower res graphics for 0.5x maginification might be provided as well.
+
+Resolution and magnification can be freely configured by the user within the given limits.
+
+In tiles this means we have 40x25 (=1280x800px) tiles per screen.
+\f
+Graphic Tasks
+=============
+
+* animate cave background torch: data/images/tiles/background/backgroundtile3.png
+
+* do parallax tiles
+
+* remove lightmap tiles
+
+* redraw/replace data/images/tiles/waterfall/
+\f
+Music Recode
+============
+
+Currently the music makes up a large chunk of the total tarball
+size. Compression could fix this:
+
+ ,-- Size of data/music/*.ogg
+ V
+40MB - Current quality in SVN
+24MB - Default oggenc quality (3)
+14MB - oggenc at 0 quality
+10MB - oggenc at -1 quality
+
+No audible difference on my sound setup. -- grumbel
