MVVM and Databinding for Unity3d(C# & XLua & ILRuntime)
Developed by Clark
Requires Unity 2018.4 or higher.
LoxodonFramework is a lightweight MVVM (Model-View-ViewModel) framework specifically crafted for Unity3D. It includes data binding and various useful components. The framework's performance is meticulously optimized, avoiding value type boxing and unboxing, minimizing garbage collection overhead. It utilizes dynamic delegates/static code weaving techniques to ensure comparable performance between data binding and direct invocation, zero garbage collection during UI view updates, and more. Additionally, it has been validated in projects, demonstrating superior performance, stability, and reliability with a clear, extensible architecture. We hope it can contribute to making your game development faster and more effortless.
For tutorials,examples and support,please see the project.You can also discuss the project in the Unity Forums.
The plugin is compatible with MacOSX,Windows,Linux,UWP,WebGL,IOS and Android,and provides all the source code of the project.
If you like this framework or think it is useful, please write a review on AssetStore or give me a STAR or FORK it on Github, thank you!

Loxodon Framework TextFormatting
This is a text formatting plugin modified based on the official C# library. By extending the AppendFormat function of StringBuilder, it aims to avoid garbage collection (GC) when concatenating strings or converting numbers to strings. This optimization is particularly beneficial in scenarios with high-performance requirements.
Furthermore, the plugin extends Unity's Unity GUI (UGUI) by introducing two new text controls: TemplateText and FormattableText. These controls support the data binding features of MVVM, allowing the binding of ViewModel or value-type objects to the controls. This approach eliminates the need for boxing and unboxing of value-type objects, thus maximizing the optimization of garbage collection (GC).
It's worth noting that using the controls TemplateTextMeshPro or FormattableTextMeshProUGUI from Loxodon.Framework.TextMeshPro can further reduce garbage collection (GC), achieving a completely GC-free update of the game view.
-
This plugin primarily serves to enhance AlertDialog and Toast views by providing TextMeshPro support, replacing UnityEngine.UI.Text with TextMeshProUGUI for optimized UI views.
Additionally, the plugin depends on the Loxodon.Framework.TextFormatting plugin, further optimizing garbage collection. By utilizing FormattableTextMeshProUGUI and TemplateTextMeshProUGUI controls, updating UI views results in absolutely no garbage collection (GC), achieving a fully GC-free view update.

This plugin supports exporting data from Excel files to Json files, Lua files, or LiteDB databases. Additionally, it enables converting data to C# objects using Json.Net. It is recommended to use LiteDB for storing configuration data, as it is a lightweight NoSQL embedded database that supports ORM functionality, BSON format, and data indexing, making it highly convenient to use.
-
This is a plugin for static code weaving, comprising multiple sub-plugins. It supports static weaving for objects, including the addition of the ToString function, integration of the PropertyChanged event, incorporation of the BindingProxy class, and more. This not only optimizes performance but also enhances development efficiency.
-
This plugin integrates UIToolkit into the Loxodon.Framework, introducing the UIToolkitWindow class. It supports data binding and allows for a mix of UIToolkit and UGUI.
-
Loxodon Framework Localization For CSV
It supports localization files in csv format, requires Unity2018.4 or higher.
-
It supports making games with lua scripts.
-
Loxodon Framework Bundle is an AssetBundle manager.It provides a functionality that can automatically manage/load an AssetBundle and its dependencies from local or remote location.Asset Dependency Management including BundleManifest that keep track of every AssetBundle and all of their dependencies. An AssetBundle Simulation Mode which allows for iterative testing of AssetBundles in a the Unity editor without ever building an AssetBundle.
The asset redundancy analyzer can help you find the redundant assets included in the AssetsBundles.Create a fingerprint for the asset by collecting the characteristic data of the asset. Find out the redundant assets in all AssetBundles by fingerprint comparison.it only supports the AssetBundle of Unity 5.6 or higher.
-
This plug-in integrates NLog into Loxodon.Framework. It is recommended to use this plug-in instead of the Log4Net plug-in. It allocates less heap memory during the log printing process.
-
This is a log plugin.It helps you to use Log4Net in the Unity3d.

The plugin is a data type memory obfuscation tool that supports ObfuscatedByte, ObfuscatedShort, ObfuscatedInt, ObfuscatedLong, ObfuscatedFloat, and ObfuscatedDouble types. Its purpose is to prevent memory modification of game values by memory editors. The plugin supports all arithmetic operators for numerical types and can automatically convert between them and their standard counterparts (byte, short, int, long, float, double).
During the obfuscation of Float and Double types, the plugin converts them to int and long types for bitwise AND and OR operations to ensure that precision is not lost. Unsafe code is used for type conversion to balance conversion performance. The plugin aims to provide a comprehensive solution for protecting game values against memory modification, allowing for seamless integration with different numerical types and maintaining performance through careful type conversion.
Example:
ObfuscatedInt length = 200; ObfuscatedFloat scale = 20.5f; int offset = 30; float value = (length * scale) + offset; -
This is a network connection component, implemented using TcpClient, supports IPV6 and IPV4, automatically recognizes the current network when connecting with a domain name, and preferentially connects to the IPV4 network.

DotNetty is a port of Netty, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.
This version is modified based on DotNetty's 0.7.5 version and is a customized version for the Unity development platform. It includes the removal of certain dependency libraries, bug fixes, performance optimizations, and enhancements to cater to game development on the Unity platform. Additionally, it has undergone testing under IL2CPP for compatibility and reliability.

private bool enabled;
private float value;
public ProgressBarViewModel()
{

public string Tip
{
get { return this.tip; }
set { this.Set<string>(ref this.tip, value, nameof(Tip)); }
}
public bool Enabled
{
get { return this.enabled; }
set { this.Set<bool>(ref this.enabled, value, nameof(Enabled)); }
}
public float Value
{
get { return this.value; }
set { this.Set<float>(ref this.value, value, nameof(Value)); }
}
}
public class ProgressBarView : UIView

public GameObject progressBar;
public Text progressTip;
public Text progressText;
public Slider progressSlider;
protected override void Awake()
{
var bindingSet = this.CreateBindingSet<ProgressBar, ProgressBarViewModel>();
bindingSet.Bind(this.progressBar).For(v => v.activeSelf).To(vm => vm.Enabled).OneWay();
bindingSet.Bind(this.progressTip).For(v => v.text).To(vm => vm.Tip).OneWay();
bindingSet.Bind(this.progressText).For(v => v.text)
.ToExpression(vm => string.Format("{0:0.00}%", vm.Value * 100)).OneWay();
bindingSet.Bind(this.progressSlider).For(v => v.value).To(vm => vm.Value).OneWay();
bindingSet.Build();
}
}
IEnumerator Unzip(ProgressBarViewModel progressBar)
{
progressBar.Tip = "Unziping";
progressBar.Enabled = true;//Display the progress bar
for(int i=0;i<30;i++)
{
//TODO:Add unzip code here.
progressBar.Value = (i/(float)30);
yield return null;
}
progressBar.Enabled = false;//Hide the progress bar
progressBar.Tip = "";
