ADR 030: Action Context

Status

Accepted

Context

Actions need access to more than just the source and target creature to function in a grid-based system. Specifically, MoveAction needs access to the IGridManager to validate paths and update positions. Additionally, actions may target positions (movement, AOE) rather than specific creatures.

Decision

We will refactor IAction.Execute to accept a single IActionContext argument.

  • IActionContext: Provides access to Source, Target, Grid, and other contextual services.
  • IActionTarget: An abstraction for action targets, allowing for CreatureTarget, PositionTarget, etc.

Consequences

  • Positive: Enables context-aware actions (Grid, Environment). Flexible targeting.
  • Negative: Breaking change for IAction. Requires updating all existing actions and tests.
