Conditionitems

Conditionitems are data constructs used to encapsulate conditional logic that governs when actions, features, or states should be enabled or triggered. They are designed to detach conditional rules from the core objects they affect, allowing systems to be configured and extended without changing primary code paths. Conditionitems can appear in software systems, games, or workflow engines as a way to model rules in a modular fashion.

A conditionitem typically includes a predicate or expression that evaluates to true or false, a target or effect that should occur when the condition holds, and context information that defines the scope of evaluation. Common fields include the condition (the boolean expression or function), the action or state to apply if true, the evaluation context (such as user role, environment, or object state), and optional metadata like priority or fallback behavior. They are commonly evaluated by a rule engine or a conditional evaluator at runtime and can be serialized for persistence or configuration.

Examples illustrate their use across domains. In a video game, a conditionitem might unlock a quest only if the player owns a specific item and has a minimum level. In a software application, a conditionitem could enable a feature flag for users with a certain role in a production environment. Benefits include modular rule management, easier testing, and flexible deployment of conditional behavior. Challenges include ensuring consistent evaluation order and managing dependencies among multiple conditionitems. See also rule engines, feature flags, and conditional logic.
