During AI perception setup, I encountered an issue where when two AI characters appear in the scene, they detect eachother and trigger pursuit. To differentiate the detected actors, this functionality is required. Unreal Official Documentation: This property can be used to set up team-based visual p...
The C++ language allows operators to be redefined sothat they work with user‑defined types in a natural way. This mechanism is called operator overloading and is essentially syntactic sugar for function calls. Adding Two Custom Objects When you need to combine two objects of a class, you can provide...
Introduction SystemC is a C++ library used for modeling and simulating hardware systems, particularly for digital and mixed-signal designs. It enables high-level architectural exploration, performance evaluasion, and software-hardware co-design without requiring specialized hardware description lang...
A knapsack problem involves selecting items with given weights and values to maximize total value without exceeding a capacity limit. It appears in resource allocation, scheduling, logistics, and investment scenarios. Problem Categories Binary Knapsack — Each item can be taken at most once. Given n...
Understanding Priority Queue A priority queue differs from a standard queue as it organizes elements based on their priority rather than insertion order. Imagine a scenario where critical tasks always take precedence over routine ones. Within critical tasks, they might be further prioritized by urge...
During copy initialization (using the equals sign), compilers may bypass copy or move constructors and create objects directly. This optimizatino is permitted but not required by the standard. std::string book_id = "123"; // Can be rewritten as: std::string book_id("123"); In thi...
Defining Classes and Objects In C++, the class acts as a blueprint for creating objects, encapsulating data (attributes) and functions (methods) into a single unit. An object is an instance of a class, allocated in memory with a specific state. By defining classes, programmers can create abstract da...
Cache Utilization Fundamentals Locality Principles Temporal Locality: Frequently accessed data tends to be reused shortly after access. This means that variables used repeatedly within loops can benefit from being cached in CPU registers. Spatial Locality: Adjacent memory locations are often loaded...
Defining the Product Abstraction Centralized factory implementations frequently depend on conditional branching to instantiate specific objects based on enput parameters. This approach violates the Open-Closed Principle because introducing new product types mandates modifications to the factory clas...
Hash tables provide O(1) average-time complexity for insertion, deletion, and lookup operations. They are the optimal choice when the primary requirement is rapidly verifying the existence of an element within a collection or tracking frequency counts. The core mechanism relies on a hash function th...
