Public Functions Documentation¶

`function` FSMState¶


FSMState()

`function` Initialize¶


virtual void Initialize(
    UObject * Instance
) override

Initialize specific properties and node instances.

Reimplements: FSMState_Base::Initialize

`function` InitializeGraphFunctions¶


virtual void InitializeGraphFunctions() override

Initialize all graph evaluator functions. Must be called from GameThread!

Reimplements: FSMState_Base::InitializeGraphFunctions

`function` Reset¶


virtual void Reset() override

Resets persistent data.

Reimplements: FSMState_Base::Reset

`function` ExecuteInitializeNodes¶


virtual void ExecuteInitializeNodes() override

Reimplements: FSMState_Base::ExecuteInitializeNodes

`function` ExecuteShutdownNodes¶


virtual void ExecuteShutdownNodes() override

Reimplements: FSMNode_Base::ExecuteShutdownNodes

`function` StartState¶


virtual bool StartState() override

Sets the state as active and begins execution.

Reimplements: FSMState_Base::StartState

`function` UpdateState¶


virtual bool UpdateState(
    float DeltaSeconds
) override

Runs the update execution.

Reimplements: FSMState_Base::UpdateState

`function` EndState¶


virtual bool EndState(
    float DeltaSeconds,
    const FSMTransition * TransitionToTake =nullptr
) override

Runs the end state execution. Transition to take is so the state knows where it is going only.

Reimplements: FSMState_Base::EndState

`function` TryExecuteGraphProperties¶


virtual bool TryExecuteGraphProperties(
    uint32 OnEvent
) override

Execute desired graph properties for the given event.

Reimplements: FSMNode_Base::TryExecuteGraphProperties

`function` OnStartedByInstance¶


virtual void OnStartedByInstance(
    USMInstance * Instance
) override

Called when the blueprint owning this node is started.

Reimplements: FSMState_Base::OnStartedByInstance

`function` OnStoppedByInstance¶


virtual void OnStoppedByInstance(
    USMInstance * Instance
) override

Called when the blueprint owning this node has stopped.

Reimplements: FSMState_Base::OnStoppedByInstance

Protected Functions Documentation¶

`function` InitializeFunctionHandlers¶


virtual void InitializeFunctionHandlers() override

Map the FunctionHandler pointer. Must be implemented per child struct!

Reimplements: FSMNode_Base::InitializeFunctionHandlers
