Setting Up Your Project for Exporting to Linux/BSD

Before exporting your game to Linux and BSD, you need to set up your project correctly. This involves configuring the export presets within the Godot editor. Here’s how you can begin that process:

var export_preset = EditorExportPreset.new()
export_preset.set_platform(EditorExportPlatformLinuxBSD.new())
export_preset.set_name("Linux/BSD")
EditorExport.get_singleton().add_export_preset(export_preset)

This snippet creates a new export preset, specifies the platform as Linux/BSD using EditorExportPlatformLinuxBSD, sets a name for the preset, and adds it to the EditorExport singleton.

Configuring Export Settings

After creating an export preset for Linux/BSD, you’ll need to configure various settings to ensure your game exports correctly. This involves setting properties such as export mode, architecture, and binary export path.

export_preset.set("export_mode", "packed")
export_preset.set("architecture", "x86_64")
export_preset.set("custom_template/release", "path/to/linux_release_template.64")
export_preset.set("custom_template/debug", "path/to/linux_debug_template.64")

These lines of code instruct your game to be packed into a single executable, target the x86_64 architecture, and define where the custom template for the release and debug binaries are located.

Exporting the Project from Code

With your presets configured, you can initiate the export directly from code. This process will generate the executable file for Linux/BSD systems.

var export_path = "path/to/game_executable"
var result = EditorExport.get_singleton().export_project(export_preset, false, export_path, false)
if result == OK:
    print("Export successful!")
else:
    print("Export failed with error code: " + str(result))

Executing this code will export the project to the defined path with the given preset. The second parameter in `export_project` indicates whether to export for debug, and the last parameter, set to false, decides whether to export all files or only the modified ones.

Handling Post-Export Operations

After exporting your game, it’s common to perform post-export operations such as moving files to a specific directory or renaming the final executable.

var file = Directory.new()
if file.rename(export_path, "path/to/final_directory/game_executable"):
    print("File move successful!")
else:
    print("Failed to move the file")

This snippet renames (effectively moving) the exported game to a desired directory. It’s essential to check if the operation succeeds to avoid any deployment issues.

Remember to replace example paths with the actual paths you’re working with and ensure you have the necessary permissions to read from/write to those directories.

By completing these steps, you will have tackled the core elements of configuring and exporting your game for Linux and BSD systems. In the next part of our tutorial, we’ll delve into more advanced export options and best practices to optimize your game’s deployment process. Stay tuned for more valuable insights and code examples that will make your Godot project export-ready for all your players!Continuing from where we left off, exporting your game to Linux and BSD systems requires consideration of various aspects such as optimizations, handling different architectures, and including additional files. Let’s jump into more complex configurations and code examples that will fine-tune your exporting process.

Optimizing Exported Files

Optimization is key to a smooth gaming experience. You can specify optimization flags directly in your export preset:

export_preset.set("binary/strip", true)
export_preset.set("binary/compress", true)

These lines enable stripping symbols from the binary, reducing file size, and compressing the binary, potentially enabling faster load times.

Handling Different Architectures

If you’re targeting systems with different architectures, it’s essential to configure your export presets to handle them correctly:

export_preset.set("architecture", "x86")  # For 32-bit systems
# Execute this code block to export for 32-bit architecture

export_preset.set("architecture", "x86_64")  # For 64-bit systems
# Execute this code block to export for 64-bit architecture

You would export the game once for each architecture and use corresponding Linux/BSD templates for each to ensure compatibility.

Including Additional Resources

Sometimes your game might rely on resources outside the main executable, such as configuration files, additional binaries, or assets:

export_preset.add_export_file("res://config/game_config.cfg", "game_config.cfg", false)
export_preset.add_export_file("res://mods/*", "mods/", true)

The first line exports a single configuration file, while the second line exports all files within the “mods” directory, preserving the folder structure.

Exporting Different Features for Different Versions

You may have certain features or content that should only be available in specific versions of your game:

export_preset.set("features/x11", true)
export_preset.set("features/bsd", false)

This configuration enables features exclusive to X11 (commonly associated with Unix-like systems like Linux) and disables features that are specific to BSD.

Post-Export Script Execution

After exporting, you might want to run a script to perform tasks like packaging or custom checks. You can automate this by integrating script execution into your export workflow:

OS.execute("path/to/script.sh", [], false)

This line runs a shell script located at the specified path. Ensure this script is executable and contains all necessary operations for your game’s deployment.

Automatic Versioning

Having proper versioning is crucial for managing releases. You can automate the versioning of your executable by modifying the export preset with your versioning system:

export_preset.set("application/config/version", "1.0.0")

This sets the game version within the export preset. You would automate this to increment with each build according to your versioning scheme.

Deploying to Online Platforms

If you plan to distribute your game on online platforms, you’ll want to automate as much of the process as possible. Integrating API calls to platform SDKs or using command-line tools provided by the platforms can help:

var platform_tool_executable = "path/to/platform_tool"
var export_args = ["--upload", "path/to/game_executable", "--user", "your_username"]
OS.execute(platform_tool_executable, export_args, false)

This code might represent executing a command-line tool for an online game distribution platform, where it uploads the exported game under your developer account.

By implementing these extended configurations and scripts, your game exportation process becomes streamlined and adaptable to various deployment scenarios. Your Linux and BSD users will enjoy a game that’s optimally packaged and versioned, ensuring a quality gaming experience. We at Zenva are committed to helping you elevate your game development skills, and mastering export configurations is an integral aspect of that journey. Keep an eye out for our upcoming articles for more tips and tricks to refine your game development process.The export process is quite akin to packaging tangible goods; attention to detail can make the difference between a seamless user experience and one fraught with complications. In our ongoing exploration of using Godot 4’s `EditorExportPlatformLinuxBSD`, it’s time to delve deeper into scripting out some essential improvements and adjustments that lend your game that professional edge.

Customizing the Export Template
Firstly, customizing your export template can inject specific functionality or optimizations. Here’s how you can specify a custom template for your Linux/BSD export:

export_preset.set("custom_template/release", "path/to/your_custom_release_template.64")
export_preset.set("custom_template/debug", "path/to/your_custom_debug_template.64")

Assigning tailored templates ensures that the exported build aligns closely with your specific needs and the expectations of your end-users on Linux/BSD platforms.

Internationlization Support
If your game supports multiple languages, it’s crucial to include internationalization (i18n) files in the export:

export_preset.add_export_file("res://localization/*.mo", "localization/", true)

This line ensures all compiled localization files are bundled with the game, allowing for dynamic language switching based on player preferences.

Handling Plugins and Dependencies
Games often depend on plugins or third-party libraries. You must ensure these are correctly packaged:

export_preset.add_export_file("res://bin/x64/libawesomeplugin.so", "libawesomeplugin.so", false)

Now, the required shared library for `libawesomeplugin` will be included in the root of the game’s export directory for easy access by the game’s executable.

Batch Processing Exports
If you plan to distribute your game across different Linux distributions, you might want to batch process exports for different configurations:

func batch_export_to_linux(export_presets):
    for preset in export_presets:
        var export_path = "builds/" + preset.get("application/config/name") + "/"
        var result = EditorExport.get_singleton().export_project(preset, false, export_path, false)
        if result == OK:
            print("Export successful for preset: "+preset.get("application/config/name"))
        else:
            print("Export failed for preset: "+preset.get("application/config/name")+" with error code: " + str(result))

By iterating through different export presets, this script allows for building multiple distributions with their respective configurations all at once.

Verifying Export Integrity
To ensure exported files are not corrupted, you can integrate checksum verification post-export:

import hashlib

def file_sha256(filename):
    sha256_hash = hashlib.sha256()
    with open(filename,"rb") as f:
        # Read and update hash in chunks of 4K
        for byte_block in iter(lambda: f.read(4096),b""):
            sha256_hash.update(byte_block)
    return sha256_hash.hexdigest()

export_path = "path/to/game_executable"
print(f"SHA-256 Checksum: {file_sha256(export_path)}")

This Python snippet generates a SHA-256 checksum for the resulting export. Using such a snippet post-export ensures the integrity of your game files before distribution.

Automating Export Workflow
Lastly, creating an automated workflow is pivotal for repeatable and efficient game exporting. Consider this example bash script for a Linux export process:

“`bash
#!/bin/bash

# Set Godot Headless Path
GODOT_HEADLESS=”/usr/local/bin/godot-headless”

# Define build paths
BUILD_PATH=”./builds”
EXPORT_NAME=”MyGameExecutable”

# Run Godot export command for Linux/BSD
$GODOT_HEADLESS –export “Linux/BSD” “${BUILD_PATH}/${EXPORT_NAME}”

# Check for success
if [ $? -eq 0 ]; then
echo “Export completed successfully.”
else
echo “Export failed. Error code: $?”
fi
“`

In this script, replace the placeholder paths and names with your actual game’s details. Running such a script in your environment can automate the entire export process end-to-end, freeing up valuable time for other development activities.

With these advanced exporting techniques, you will have greater control over your game release’s success on Linux and BSD platforms. We at Zenva strive to arm you with the knowledge to navigate these technical challenges, paving the way for your projects to shine across all user landscapes.

Remember to tailor each script and setting to align with your game’s unique needs and structure. By embracing automation and custom configurations, you streamline your workflow and reinforce the reliability of your game exports. Keep experimenting and fine-tuning – the mastery of these skills defines the expertise of a seasoned game developer.
