I'm no longer using C++ for personal projects, thus this project's development has been discontinued. Check my GitHub or my website for projects coming in the future.
Before compiling on linux, make sure you have the clang compiler, with C++17 supported. GalaEngine should compile with g++, however it has not been tested.
To compile, simply execute the build_demo_linux64.sh file. Please note that build_engine_linux64.sh will produce a standalone library in the future, however this is not supported at the moment.
GalaEngine does not have an official Windows build script yet, but feel free to check out the linux build scripts to create your own build.
FOR USERS OF THE LATEST RELEASE: Documentation is hosted here.
Documentation for GalaEngine exists within each header, formatted with Doxygen comments, and within the Docs/ folder. Although these can be read manually, it is recommended you check out the hosted documentation online, or build the documentation using Doxygen.
If you do not have Doxygen installed, you may download and install it here. If you are on Ubuntu, you can simply install it by running sudo apt-get install doxygen.
To build the documentation, open the directory you have cloned GalaEngine to, and run the following command:
doxygen Doxyfile. This will generate the appropriate HTML in the Docs/html/ directory. To view the documentation, simply locate and open the Docs/html/index.html file in your web browser of choice.
If you'd like to contribute to GalaEngine (firstly, thank you!), there are a few guidelines expected to be followed. Following these guidelines makes managing and maintaining GalaEngine cooperatively much easier.
If you've found a bug while using GalaEngine, creating a report in the "Issues" section of this GitHub repository is recommended. Creating a well-structured bug report is appreciated, as it makes the process of communicating and fixing the bug as easy as possible. A good bug report should:
- Be well-titled. A good title structure is as follows:
<Subject|Object>: ([<Issue> "when"] <Action>) | (<Summary>).. Examples of good titles are:Entity: Crash when changing sprites.,InputManager: Fails to recognise bluetooth controllers., andDocs: Scene.hpp has outdated TODO.. Examples of bad titles are:Entities crash the game.,Scenes are too confusing., orHow do I change the colour of a sprite?. - Have a good explanation in comment. The comment of your issue should explain the expected behaviour, the actual behaviour, how to reproduce the bug, and the platform you are using GalaEngine on (are you using Windows or macOS? what GPU do you have?). If your bug or issue does not require such details (as in the case of a documentation error), it's fine to simply suggest an edit or clarification.
- Be properly tagged. Properly tagging your issue can help maintainers and newcommers understand the current issues within GalaEngine. You can tag your issue by selecting a label when creating it.
In addition to the title, it is a good idea to supply further infromation in the comment. Here's some useful information that is appreciated to include in a pull request comment:
- Recap the problem as described in the title.
- What caused the problem?
- How did you solve the problem?
- Has this been reported before? (Include a link to an Issue if you have one!)
- Provide an example of how your solution works in practice, versus the result before the fix. (Such as a code example, or screenshots.)
If you wish to contribute to the source code of GalaEngine, you may do so by forking the repository and creating a pull request. It is recommended to commit to your fork in small steps, and properly comment your changes.
When you are ready to make a pull request, make sure to include some information about your changes. A good title for a pull request is as follows: <Verb>: <Object>: <Action>., or <Verb|Category>: <Action> for simpler changes. Examples of good pull request titles are:
Fixed: Scene: Stale-pointer deletion on RemoveLayer().Implemented: Debug::Logger class.Docs: Updated Scene.hpp.
