DodgeR (gdext evaluation project)

This is part of a project to evaluate the godot-rust bindings gdext.

It is derived from the Dodge-the-creeps example game: gdext dodge-the-creeps, which is a finished Rust version of the game featured in the "Your first 2D game" tutorial in the godot documentation.

Language: Rust

Renderer: Vulkan Mobile

The evaluation project consists of four Repositories:

• overview repository (contains raw data, results and a description of the evaluation process)
• this
• GDScript Version
• process-logger
• python-pandas-plotter

Setup

• Installing Support for the Vulkan Renderer might be required.

If the prebuild executables should not work for you, you can build the project from source with the following steps:

1. Install Rust
2. Download Godot 4.2
3. Setup gdext by making the Godot executable available. Either way by:
   • putting it in your PATH as godot4
   • or as an environment variable called GODOT4_BIN, containing the path to the Godot executable.
4. Clone this repository by opening a shell and entering:
   • git clone git@github.com:franziskusz/dodge-r.git (requires having a ssh key setup)
   • or git clone https://github.com/franziskusz/dodge-r.git
5. Change to the just cloned repository directory with cd dodge-r (Unix)
6. Run cargo build and cargo build --release (this project is configured for performance. A full release build is expected to take over 10 minutes)
7. Open the dodge-the-creeps/godot/project.godot file by double clicking it.
8. With entering command b or clicking the triangle on the top right you can run the project within the editor in debug mode
9. In the menu select Project -> Export... to export the release build
10. Select Add.. at the top/center to add a Preset for your Operating System (This might require an additional autmatic download)
11. Select Export Project at the bottom and chose a name and target directory, deselect Export With Debug and click on Save

Notes

• To dodge breaking changes of the gdext bindings I included a local version within this repository (/gdext/). It is an unmodified Version from early January 2024.
• I am new to Godot and Rust. This whole project is also a learning experience for me. If the way some things are implemented gives you headaches, I apologize. I am open for any kind of criticism.
• .csv logging is based on the Rust crate csv
• The additional calculation workload is based on godot-rust-benchmark
• This applications writes performance logs to timestamped .csv files within the /app_userdata/DodgeR/stats/ directory. See godot file paths for details. This directory will never get cleared automatically!
