Solution Overview
Problem
Large and complex resource files in computer games lead to slow loading speeds and inefficiencies, causing resource wastage and degrading operation performance.
Innovation Solution
A method and apparatus for loading game engine resources that involves preloading resource files using threads, memory mapping for structure and model files, and non-synchronous loading of scene reorganization, shader compiling, and texture files, utilizing shared contexts and hardware decoders to accelerate loading speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If resource files are loaded sequentially using conventional methods, then memory access is simple, but loading speed is slow and operation efficiency is degraded
Solution Approach 1:
The patent applies preliminary action by preloading resource files into memory before they are actually needed during game operation. The system proactively loads texture, model, and script files into memory buffers, so that when these resources are required, they are already available for immediate use, thereby significantly reducing loading time and improving responsiveness.
Solution Approach 2:
The patent segments the resource loading process into multiple independent threads, each responsible for loading specific resource types (textures, models, scripts). This segmentation allows parallel processing of different resource files, eliminating the sequential bottleneck and dramatically improving overall loading speed while maintaining manageable complexity through modular thread design.
2Reliability
If large resource files are loaded into memory, then resource availability is improved, but memory consumption increases causing resource wastage
Solution Approach 1:
The patent divides large resource files into smaller segments or chunks that can be loaded into memory individually. Instead of loading entire large files at once, the system loads only the necessary portions or uses memory mapping to access files without fully loading them into RAM, reducing memory consumption while maintaining resource availability.
Solution Approach 2:
The patent introduces memory mapping as an intermediary mechanism between the disk-based resource files and the application's memory space. This allows the system to access large resource files through a virtual memory layer, providing the appearance of having files fully loaded in memory while actually using disk storage, thus reducing physical memory consumption.
3Productivity
If conventional sequential loading is used, then system simplicity is maintained, but operation efficiency and activation speed are degraded
Solution Approach 1:
The patent implements segmentation by creating separate threads for loading different resource types (textures, models, scripts). Each thread operates independently and can load its resources in parallel, significantly improving operation efficiency. The thread management complexity is controlled through standard threading APIs and synchronization mechanisms that coordinate between threads without requiring complex custom management.
Solution Approach 2:
The patent ensures continuity of useful action by having multiple threads load resources simultaneously and continuously, rather than sequentially waiting for one another. The thread pool maintains active loading operations throughout, so that resource files are constantly being loaded or are already loaded and ready, eliminating idle waiting time and maximizing system productivity.

AI summary
A method for loading a resource file for a game engine is provided. The method includes: activating a thread to a preload a predetermined resource file, wherein the predetermined resource file includes a texture resource file, and one or both of a structure resource file and a model resource file; and accessing and loading one or both of the structure resource file and the model resource file through memory mapping. The provided method increases a loading speed while loading a game resource file and fully utilizes computer resources.
