OneShot

OneShot, in various contexts, refers to something that happens, or is intended to happen, only once. The specific meaning varies depending on the field of application.

In gaming, particularly tabletop role-playing games (TTRPGs), a OneShot is a self-contained adventure or campaign designed to be completed in a single session of play. This contrasts with longer campaigns that unfold over multiple sessions. OneShots are often used for introducing new players to a game system, testing out new character concepts, or providing a short, focused gaming experience.

In computer science, specifically in event handling and memory management, a OneShot may refer to a function or operation designed to execute only once. For example, a OneShot timer triggers an event only once and then stops, unlike repeating timers. Similarly, a OneShot signal might be designed to trigger a specific process or function only upon its initial activation.

In photography, a OneShot may refer to capturing a particular moment or image perfectly on the first attempt, without needing multiple takes. This usage emphasizes skill and preparedness in capturing a fleeting opportunity.

Generally, the core concept of "OneShot" revolves around a singular instance or execution of an event, action, or process, highlighting its non-recurring nature.
