colobot / colobot

Source code of open-source Colobot: Gold Edition project developed by Epsitec and TerranovaTeam

This is the main repository for the open-source Colobot: Gold Edition project developed by TerranovaTeam and community contributors, based on the original game by Epsitec.

This repository contains only the source code of the project. The game also requires data files which are provided as a git submodule and are hosted in a separate repository.

Features

• Multiplatform - play the game on any modern OS.
• New game modes - challenge yourself in Missions+ or challenge your friends in CodeBattles.
• Mod support - download custom levels and assets from our ModDB page.
• Improved visuals, QoL additions, bug fixes, and other improvements.

Download

Stable releases

Official builds for Windows, Linux, MacOS are available here:

Linux packages:

Development builds

Development builds are compiled every push to the repository by GitHub Actions:

Compiling from source

Instructions on how to build the game from sources are available for the following environments:

• Linux
• Windows (MSYS2)
• Windows (MSVC)
• MacOS

colobot's Issues

Classes inheriting from CAuto have doubled constructor calls and explicitly called destructors

"Effects" clasess in graphics engine need to be rewritten

CParticle, CLighting and CPyro.
For now implemented as stubs, as not essential to core graphics engine.

CEdit is buggy

Deleting characters works, but entering text doesn't. This makes entering cheat codes impossible.

CBOT - Method overloading is buggy

Needs more exploration, seems to depend on the order of declaration of the functions

CBOT - not returning a value in a function that expects one crashes the game

A function that sometimes returns a value and sometimes doesn't will crash the game. It should display a compile or runtime error instead.

string test(int i) {
if (i == 0) {
return "works"
} else {
//no return, crashes colobot.exe
}

Comparing vector to float in autoegg.cpp

GCC error (with libwine headers):
autoegg.cpp: In member function ‘virtual void CAutoEgg::DeleteObject(BOOL)’: autoegg.cpp:79:30: error: no match for ‘operator==’ in ‘alien->CObject::RetZoom(0) == 1.0e+0f'

Direct operations on file paths and the use of _prgname

in sound.cpp, function GetCurrentDir() and probably other places

Broken graphics when compiling under different compiler

Graphics are broken when compiling with any compiler other than MSVC6. Probably a bug in loading textures of graphical effects. Example: http://s7.postimage.org/521zhu9zv/colobot_win7.png

DAT file reader/writer makes invalid assumptions

The CMetaFile class (metafile.cpp), which reads and writes the DAT files used to store models and textures, reads and writes entire structs instead of writing field-by-field. The code will break if it is compiled for anything other than IA-32 hardware or if the compiler rearranges fields or inserts padding between fields.

To fix, either (a) specify an endianness, field order, and padding and change the code to obey or (b) unpack the models and textures into individual files and remove the DAT file code entirely.

Main graphics engine needs to be rewritten

Main graphics engine (src/graphics/engine) needs to be rewritten to use abstract graphics device.

Bugged in-game CBot editor.

Bugged saving/reading (wrong folder). Bugged editor.

Event processing doesn't work properly

This needs further investigation, looks like smoething is broken after code rewriting/rafactoring.

Clean all warnings generated by gcc (except those from gtest)

Sound engine needs to be rewritten

Work in progress by erihel in his own fork. What library to use is still to be decided.

Comments are written in French

We need to translate it into English

WinAPI framework needs to be rewritten to SDL

Work in progress in dev-opengl branch.

"invradar" cheat code doesn't work

Entering "invradar" doesn't change anything. It should cause minimap to show aliens etc. as if RadarStation existed.

New graphics code needs to be tested

New code in src/engine needs through testing & verification against the original code

Missing includes, case of letters in file names

Comments are written in French

We need to translate it into English

Objects are blue

Objects have the default blue color instead of color given in mission file (VehicleColor instruction).

Invalid copy constructor

in example
CBotTypResult::CBotTypResult(CBotTypResult& typ)
needs to be changed to
CBotTypResult::CBotTypResult(const CBotTypResult& typ)

Distracting objects should be semi-transparent

When some object is selected and other object covers it, the latter should be semi-transparent and untextured.

A logging system needs to be written

Instead of using WinAPI's OutputDebugString(), we need a proper logger. Perhaps in the future integrated with an in-game console.

Declaration of two CImage classes

src/ui/image.h
common/image.h

My suggestion - put every class from src/ui into ui namespace

2D interface needs to be rewritten

2D user interface in src/ui needs to be rewritten to use the new graphics code.
Work in dev-ui branch

Game relies on DirectX

We should port it to OpenGL or some graphics engine (such as Irrlicht).

PowerStation does not charge PowerCells

When astronaut stays on PowerStation platform with battery in hand, nothing happens.

Graphics: fix light

For now, ground is usually too dark and objects too bright.

CBOT - using static initializers in classes crashes the game

This code:

public class exchange
{
static private bool global = null;
}

Causes immediate game crash at hitting "OK" button in program editor.

Copie de taskgoto.cpp, restext-old.cpp and winmain.cpp can be deleted

We should convert project to CMake

Changing keys in Options doesn't work

Changing controls keys in "Controls" tab of "Options" window doesn't work.

Destroying objects doesn't work

When shieldLevel goes down to 0, object is deselected but not destroyed. It applies to aliens, too.

Crash when saving the mission state

"extern inline" functions

in math3d.h and math3d.cpp

Non-standard usage of DirectX structures

for example in object.cpp

NEEDS_VERIFICATION: SpaceShip collisions aren't working

You can't enter the SpaceShip

Comments are written in French

We need to translate it into English

Selecting objects doesn't work

Clicking on object doesn't select it, but the yellow frame is shown correctly when moving cursor onto the object.

Remove old #ifdef code

Old code based on #ifdefs for _FULL, _TEEN, etc. needs to be removed or flagged as possible for use in alternate version. Each occurence should be marked with TODO comment in the code.

Remove passing temporary object as pointer

Remove passing temporary object as pointer so it will be possible to compile code without fpermissive flag.

in-game CBot editor is buggy

• It gives random characters at line begin and end
• font isn't monospace after changing something in program code
• When viewing program while it's working, currently running function isn't highlighted
• Moving editor window doesn't move controls inside it

Flags don't show in 3D view

After setting up a flag by Astronaut, it is visible on map but invisible in 3D view.

License info doesn't have link to GNU GPL license

This is bug in original text from Epsitec, "If not, see ." should be replaced with: "If not, see http://www.gnu.org/licenses/."

Crash when loading mission if compiled with MinGW

Graphics engine needs to be rewritten to OpenGL

Work in progress in dev-opengl branch.

Implement listing directories

There is no available download for a fully compiled game

This would have include music, as well as all available languages, and their patches. Any hostings which would be nice enough to provide space for us, which wouldn't involve limits, or looking shady?

Including a cpp file in robotmain.cpp
