static TAutoConsoleVariable<FString> CVarRepGraphConditionalBreakpointActorName(TEXT("Net.RepGraph.ConditionalBreakpointActorName"), TEXT(""), 
    TEXT("Helper CVar for debugging. Set this string to conditionally log/breakpoint various points in the repgraph pipeline. Useful for bugs like 'why is this actor channel closing'"), ECVF_Default );

// 使用:
FORCEINLINE bool RepGraphConditionalActorBreakpoint(AActor* Actor, UNetConnection* NetConnection)
{
#if !(UE_BUILD_SHIPPING)
    if (CVarRepGraphConditionalBreakpointActorName.GetValueOnGameThread().Len() > 0 && GetNameSafe(Actor).Contains(CVarRepGraphConditionalBreakpointActorName.GetValueOnGameThread()))
    {
        return true;
    }

    // Alternatively, DebugActorConnectionPair can be set by code to catch a specific actor/connection pair 
    if (DebugActorConnectionPair.Actor.Get() == Actor && (DebugActorConnectionPair.Connection == nullptr || DebugActorConnectionPair.Connection == NetConnection ))
    {
        return true;
    }
#endif
    return false;
}
