Struct PhysicsAgent 

pub struct PhysicsAgent { /* private fields */ }

The agent responsible for managing the physics simulation.

Holds only its own strategy state — the PhysicsProvider is fetched from EngineContext::services per frame.

Trait Implementations

impl Agent for PhysicsAgent

fn id(&self) -> AgentId

Returns the unique identifier for this agent.

fn negotiate(&mut self, _request: NegotiationRequest) -> NegotiationResponse

Negotiates with the DCC to determine the best execution strategy given the current global resource constraints and priorities.

fn apply_budget(&mut self, budget: ResourceBudget)

Applies a resource budget issued by the DCC. The agent must adjust its internal logic (e.g., LOD, quality settings) to stay within the allocated limits.

fn on_initialize(&mut self, context: &mut EngineContext<'_>)

Called once after the agent is registered with the DCC.

fn execute(&mut self, context: &mut EngineContext<'_>)

Called every frame by the engine loop.

fn report_status(&self) -> AgentStatus

Reports the current status and health of the agent.

fn as_any(&self) -> &dyn Any

Allows downcasting to concrete agent types.

fn as_any_mut(&mut self) -> &mut dyn Any

Allows mutable downcasting to concrete agent types.

fn execution_timing(&self) -> ExecutionTiming

Declares WHEN and HOW this agent should execute within the frame pipeline.

fn access(&self) -> AgentAccess

Declares this agent’s data-access footprint during execute, so the scheduler can decide whether it is safe to run concurrently with other agents in the same phase.

fn deck_writes(&self) -> Vec<TypeId>

Declares the OutputDeck slot types this agent writes during execute, by TypeId.

impl Default for PhysicsAgent

fn default() -> Self

Returns the “default value” for a type.
