Improbable.Worker.Authority enum
Summary | Enumerates the possible states of an AuthorityChangeOp. Authoritative and NotAuthoritative are used to indicate the worker has gained or lost authority (respectively) over a particular component for an entity. AuthorityLossImminent is only used when the component has an authority handover timeout set, and indicates the worker will soon lose authority soon over a particular component for an entity. In this case, the worker may save any transient state by sending a final update for the component, and call SendAuthorityLossImminentAcknowledgement to proceed with authority handover. Note that this should only be used for optimization purposes, and workers must still be able to recover in case the final update is not successful. In general, there is no guarantee that a worker will receive the authority loss imminent notification in time to send a final update. |

Improbable.Worker.StatusCode enum
Fields
StatusCode
ApplicationError
- The command was delivered successfully, but the handler rejected it. Either the command was delivered to a worker that explicitly rejected it by calling SendCommandFailure, or the request data was rejected as invalid by SpatialOS itself. In the latter case, in particular, SendCreateEntityRequest will return ApplicationError if an entity ID reservation has expired, and SendEntityQueryRequest will return ApplicationError if the result set is incomplete.StatusCode
AuthorityLost
- The request could not be executed by a worker, either because it lost authority while handling the request, or because no worker was authoritative at all. Assuming the deployment isn’t irrecoverably broken (e.g. due to misconfigured loadbalancing or crash-looping workers) this is a transient failure and can be retried immediately.StatusCode
InternalError
- Some other error occurred. This likely indicates a bug in SpatialOS and should be reported.StatusCode
NotFound
- The target entity did not exist, or did not have the target component. This probably means the entity either hasn’t been created yet or has already been deleted. It might make sense to retry the request if there is reason to believe the entity hasn’t yet been created but will be soon.StatusCode
PermissionDenied
- The worker did not have the required permissions to make the request. Permissions do not change at runtime, so it doesn’t make sense to retry the request.StatusCode
Success
- The request was successfully executed and returned a response.StatusCode
Timeout
- The request timed out before a response was received. It can be retried, but carefully - this usually means the deployment is overloaded, so some sort of backoff should be used to avoid making the problem worse. This can also be caused by the target worker’s handling code failing to respond to the command at all, perhaps due to a bug in its implementation.

Improbable.Worker.ThreadAffinityParameters class
Summary | Parameters for configuring the affinity of threads started by SpatialOS workers. This is only intended for use on console, however support exists on all platforms except macOS where there is no strict concept of thread affinity. Instead, we set the thread policy which expresses hints to the scheduler. Affinity masks are bit masks where setting 1 in the nth least significant position means the thread will be permitted to run on the nth core. If an affinity mask is set to zero, the group of threads using that mask will have no thread affinity and be allowed to run on any logical core. Setting the affinity mask to permit a core index which does not exist is undefined behaviour, and we are not performing any checks at runtime whether the logical core count accommodates the affinity masks. |
Fields and Properties
ulong ReceiveThreadsAffinityMask = 0
- Affinity mask for threads related to receiving data from the runtime.ulong SendThreadsAffinityMask = 0
