Changelog

implemented locales. (almost) every text can be translated to other languages (game messages, error messages, dialogs, names of items and characters). this makes creating dialogs a little bit more complex, but I hope it's worth the effort

implemented toggle delay also for fullscreen toggling. otherwise faster computers would switch more than once on a single key press

quit dialog: any other key than ESC resumes game

improved quest system. available player dialogs may depend on completed quests

quadratic font maps. this saves about 94% of texture memory for each font map, because we had to resize them to power of two dimensions

special objects can be marked as non passable with the solid keyword

event system to trigger special events like teleporting the player, changing the map through a dialog or changing the player image

theme support for maps. no more butterflies in the desert :/

switch to cmake for makefile generation

start coordinates for world and player editable through config file

several code improvements

the „damn the machine“ release

implemented skill level. visibility of characters, items and objects depends now on player progress

characters may give items to player or take them away

improvements get randomly (horizontally) mirrored on level load

moved improvements code from world.cpp to own file world_improvments.cpp

more flexible parser of map items, characters and objects

fixed bug in font drawing where fontmaps with different character widths weren't drawn properly

added additional larger font used to inform player about special events

fonts use antialiasing

added delay between toggling of auto pickup / auto talk and graphical messages to show the current state of them

game no longer refuses to start if there is no audio device

sound can be disabled via config

added shadows to player, characters, items and improvements

several small code reworks

the „no silly name this time“ release

disabled auto pickup of items and auto talks to characters by default, can be toggled ingame and through the config file

almost every key is now configurable through the config file

some minor tweaks

the „all hail to Rock'n'Rolf“ release

more flexible dialog system implementation. you can declare multiple items required or forbidden for a specific dialog message to appear

implemented object system where you can put simple objects (just images) on the map

added some quests for testing purposes

thanks to Emat0r's magnificent ideas, we now have a quit dialog

item dependend dialog system. dialogs appear whether you picked up a specified item or not (needs further improvements)

message system added. player is informed about picked up items, talks to characters and level changes

support for alpha channel images. now we can handle images with real transparency (e.g. with PNG)

some minor code enhancements

the „with lots of cool bonus stuff for people who like cool bonus stuff“ release

implemented simple item system

fixed memory leaks (forgot to delete special character texture on level change and accidently loaded new texture every dialog call). now this program should finally be free of any memory leaks. wheee.

several code cleanups/reworks

icon for windows executable

the „nothing new for you“ release

converted code indention from tab to 4 spaces

the „new year, new feature“ release

dialogs have sound

the „free as an eagle“ release

added random occurring events (at the moment flying butterflies/birds)

skipping to last dialog choice possible

changed key mapping for quitting dialog choice

reduced player speed

map file names now have “.txt“ ending

new forest texture

switching between window and fullscreen now also under MS Windows possible

copy of GPL gets shipped with source code tarball

added copyright notice to source files

each level has now it's own title

keypress during dialog skips to next message

dialogs can be left at any time

ship README

some changes to the code layout

additional font config options

now all texture sizes get converted to power of two. strangely drawing nonpower of two textures didn't create any problems unter GNU/Linux, and MS Windows with very old detonator graphics drivers (= my test box)

clear screen and depth buffer on startup

some changes to the code layout

new character and new map

rescaled some textures to power of two size

now we mostly use OpenGL for drawing, thus allowing real hardware acceleration

player now produces silly footprints

dialog system:

new character

the „beware of the litchen“ release

forgot to use config values in World::improve_terrain()

improvements aren't drawn above each other any more

changed resolution from 800×600 to 1024×768

thus, increased texture size (tex_size) from 40 to 64 pixels

thus, decreased level width from 20 to 16 and level height from 15 to 12 tiles

thus, created new textures from scratch and reworked some old ones

minor code improvements

additional config options

added config (config.cfg), most values are now editable through this file

added additional checks to prevent crashes

implemented dialog choices

improved dialog system

some minor graphics improvements, new title logo and new gui panel

fixed bad memory leak (~+4MB per level change), existed probably since v0.2.6

the „this project is not dead“ release

game now exitable inside intro screen

intro screen does not use full CPU anymore

(very) simple dialog system

fixed typo in collision detection, should now be accurate

special characters are not passable anymore (due to dialog system), unfortunately collision detection of these characters is really bad

now we use SDL_image, thus we can also load other image formats than BMP

improvements are now drawn on 2×2 field with at least three same textures (not four, as in the past)

fixed bug #0003 (see http://www.choerbaert.org/wiki/bert:bugs)

increased compatibility by using SDL_ANYFORMAT on video surface

smooth texture transition by drawing single pixels around the border (through direct pixel access)

fixed bugs #0001 and #0002 (see http://www.choerbaert.org/wiki/bert:bugs)

now we use SDL_GetKeyState instead of SDL events, which are simpler and make the code easier redable

improvements and special characters are now drawn above player if player is behind (north of) these objects

terrain textures are now drawn randomly if there are more than one (see tex_grass.bmp and tex_forest.bmp for examples)

fixed logical error (or maybe typo?) in calculation of framerate

special characters are now animated

improvements are now animated

increased number of animation frames from three to four

fixed memory leak in LoadBitmap() (exists since last version)

reduced texture loadings through storing surfaces of textures and improvements rather than source of the texture

changed FPS from 30 to 20 and APS from 5 to 3

now LoadBitmap() converts surface to the pixel format and colors of the video framebuffer, thus enabling faster blitting, which results in a significantly reduced cpu usage

replaced SDL_UpdateRect() by SDL_Flip in Intro() (forgotten in 0.2.1)

added window title

pressing 'f' now toggles fullscreen ingame

made source code doxygen friendly and include Doxyfile (configuration file for doxygen)

note: this release doesn't include any game play relevant changes, thus it is only attractive to developers

srand was called several times (after Intro() and on each level load), removed the latter

implemented fixed number of frames per second (later, it may be possible to set FPS through config file), but i have doubts that this isn't really working as wanted

thus, we could also significantly reduce cpu usage

adjustable animations per second (maybe later also through config file), because this depends on the FPS-code, it may also be buggy

fixed logical error in Player::draw() whereby the wrong (opposite) level was loaded when moving to the north/south, therefore we ship also an additional map to have an example of vertical level changes

additional code comments

reworked movement system: now supports moving diagonal, additionally all hangs should be eliminated

now we use double buffering if the graphics card supports it

made code fit on terminals with 80 columns

print errors to stderr instead of stdout

commented out all debug messages since they aren't interesting for non-developers

included SDL/SDL.h instead of SDL.h for compatibility reasons

maybe i should have made this to 0.2, damn versioning system :)

now you can place so called „special characters“ on each map (currently they have no role), see example in maps/world5050

World::draw() reworked, path now needs to be passed as first argument instead of the tile, allows more flexibility

minor code improvements

additional code comments

print more debug messages

terrain will now be improved by searching for 2×2 fields with the same texture and placing an „improvement texture“ in the center of them

old textures replaced by more realistic textures (maybe you can choose between realistic and comic-style textures in the future)

every class has now it's own header- and implementation-file

smoother movement, player now moves only 1 field instead of 40 if a cursor is pressed

easier movement, now you can leave the cursor pressed to move the player

collision detection, player can't move on fields which tileset identifier is uppercase (collision detection is a little bit buggy at the moment)

bitmap fonts

fixed very bad memory leak (level background wasn't freed when new background was loaded)

very simple gui-panel
