DG - Domini Games test task

Overview

This project is a small game engine developed using SDL and OpenGL. It features basic movement controls with the WASD keys, allowing players to navigate the environment. The left shift key enables sprinting for faster movement. The left, right move light source along x axis, up, bottom - along y and z, x along z axis. The camera can be rotated using the mouse, providing an immersive experience. Additionally, the engine includes a lighting system, though it may have some inaccuracies. Overall, this test assignment showcases fundamental game mechanics and graphics rendering capabilities.

BUILD

Linux

install dependencies:

pacman -S cmake mesa ninja clang

NOTE: you need C++ compiler which support C++20

from root project folder:

cmake -S orbi/ -B build -G Ninja
ninja -C build/

additional options: -DDG_ENGINE_TEST=ON/OFF, -DDG_ENGINE_SANITIZER=ON/OFF, -DDG_ORBI_SANITIZER=ON/OFF, -DDG_ENGINE_PEDANTIC=ON/OFF, -DDG_ORBI_PEDANTIC=ON/OFF

run with:

./build/orbi

Android

move to android-project:

cd orbi/android-project

firstly you need to install NDK. I recommend to install cmdline-tools and gradle will do the rest for us. Here is official documentation

Also add local.properties file in android-project with path to android-sdk. Something like that for my pc.

sdk.dir=/home/missed/code/dg/orbi/android-project/android-sdk

Carefully read and accept licenses.. Or just yes | ./android-sdk/cmdline-tools/latest/bin/sdkmanager --licenses if you dont like all this lawyer nonsense.

After connect your phone and just run:

./gradlew installDebug

Windows

Isn't tested, but also should work with minor fixes. How to configure environment on I will leave to Windows lovers :)

UPD: ok, I test this)

cross-build with:

cmake -S orbi/ -B build-win -G Ninja -DCMAKE_TOOLCHAIN_FILE=(realpath cmake/cmake-toolchain-mingw64-x86_64.cmake) -DDG_ENGINE_SANITIZER=OFF -DDG_ORBI_SANITIZER=OFF
ninja -C build-win/

Unfortunately wine a little drunk and it refuse all my tries to launch this... But all should work on real Windows

If you feel the power, try:

WINEPATH="/usr/x86_64-w64-mingw32/bin/;$(pwd)/build-win/_deps/sdl3-build/;$(pwd)/build-win/engine" ./build-win/orbi.exe

or call wine manually, if your haven't properly configured xdg-open

Known issues

• ambient and diffuse lightning implemented, but works with glitches in orbi due to incorrect loading of normals from .obj file
• memory leak
  on my machine this is always 3730 bytes. It reproduces even on simple example with SDL_Init and SDL_Quit. So, maybe SDL just leave memory unfreed, because app althrough will exit. On other SDL backend behaviour may differ.
