To do a good job, one must first sharpen their tools! AIGC tools represented by ChatGPT and Stable Diffusion have emerged, and the AI wave is sweeping across various industries. As developers, how to leverage AI capabilities to improve efficiency in tasks is a question worth studying.

It is crucial to note that the content generated by GPT may not be entirely accurate and can contain inaccuracies. However, its potential lies in the possibility of achieving a general-purpose AI assistant. No one can possess expert-level knowledge in all fields, but effectively utilizing GPT in unfamiliar domains can significantly lower the entry costs.

In this article, I will introduce some cases of using GPT to assist in work, life, and learning, as well as explore application scenarios for secondary development using the GPT API. At the end of the article, I will share some Prompts I use and recommend some useful GPT tools, as well as a solution for encapsulating Azure OpenAI services using Cloudflare Worker.

DevOps is a philosophy based on automation for Continuous Integration (CI) and Continuous Deployment (CD), optimizing all aspects of development, testing, and operations. It emphasizes the integration of software development, testing, and operations, reducing communication costs between departments or processes to achieve rapid and high-quality releases and iterations.

Although the development situation in the gaming field differs significantly from traditional internet development, leveraging the concept of DevOps to integrate all production elements of a project into automation can greatly enhance efficiency.

This article will introduce the basic concepts of automation in UE and share some of my attempts and actual engineering practices regarding automation builds in Unreal Engine.

Recently, there is often a strange sense of anxiety. After a period of self-observation and reflection, I believe it is necessary to confront these issues and attempt to provide answers.

This article is a thought experiment that examines and analyzes the current state of life and its problems, summarizing the ideological tools for guiding life and work. As a personal methodology, it contains a large amount of subjective content.

In game project development, a large number of developers from various aspects such as development, art, planning, and outsourcing will be involved. For reasons of resource security and information confidentiality, complex permission controls and synchronization logic are usually implemented.

However, leaving aside permission control and focusing on the resources themselves, in UE, resources are upward compatible, meaning resources can be opened directly with the same version engine or a higher version engine. This means that distributed resources can be used directly in other projects. Therefore, ensuring the security of resources during the development phase is a key focus.

This article provides an idea for encrypting the original UASSET resources in the project and introduces the basic principles that can be used for resource encryption. However, publicly disclosing the specific encryption implementation would be akin to running naked, so this article will only provide an analysis of the uasset resource structure and ideas for implementing encryption, but will not provide specific implementation code.

When using the Unreal Engine development tool, a significant number of tasks involve resource processing and data export needs. These tasks need to be performed frequently and automatically, often integrated into a CI/CD system.

In the specific implementation, the Commandlet mechanism of UE is utilized to drive the engine in a command-line manner, performing custom behaviors.

Taking the Commandlet features supported in the plugin I developed as an example:

1. HotPatcher: Export basic package information, pack patches
2. ResScannerUE: Incremental scanning of changed resources
3. HotChunker: Standalone packaging of Chunk
4. libZSTD: Training Shader dictionaries
5. ExportNavMesh: Export NavMesh data

Commandlet allows for easier integration into CI/CD to achieve automation.

In this article, I will primarily introduce the Commandlet mechanism of UE, analyze its implementation principles, and provide some development tips and insights from my development process.

Additionally, this is the second article in my UE Plugin and Tool Development series, which will continue to be updated, so stay tuned.

I previously wrote an article introducing UE’s default unpacking method (UE Hot Update: Splitting the Base Package), but the default unpacking method in UE is not flexible enough for large-scale resource projects and cannot meet the refined management needs of super-large-scale resource projects.

To address the issues with UE’s default packaging and resource splitting pain points, I developed an extension based on HotPatcherCore that can solve the drawbacks of the default unpacking process, making it sufficiently flexible and powerful. There’s an article on the blog that introduces its overall implementation mechanism: A Flexible and Non-Intrusive Base Package Splitting Solution.

HotChunker can be integrated into UE’s default packaging process non-intrusively, requiring no manual handling. As long as the default UE packaging is done, it will automatically trigger HotChunker’s unpacking process, achieving resource cooking, packaging, and automatic copying to the StagedBuilds directory.

This article will focus on how to configure resource splitting using HotChunker, automate builds, minimize resource redundancy, and implement parallel packaging.
