constHit

constHit is a term that can appear in various programming contexts, often related to collision detection or raycasting. In essence, it refers to a successful detection of an intersection. When a ray or a projectile is fired in a virtual environment, constHit signifies that it has encountered an object or surface. This "hit" carries information about what was struck and where the impact occurred. The term "const" within constHit often implies that this information is immutable or read-only once the hit is registered, meaning it cannot be changed after detection. This is a common design pattern in many game engines and physics simulations to ensure data integrity. The data associated with a constHit typically includes the point of impact, the normal vector of the surface at that point, and a reference to the object that was hit. This information is crucial for subsequent game logic, such as applying damage, triggering events, or determining the trajectory of a reflected projectile. Without constHit, determining interactions between objects in real-time would be significantly more complex and computationally expensive. Its presence simplifies the process of managing and responding to these interactions.
