func (*Alpha) DecrementCounter ¶ added in v1.35.0

func (a *Alpha) DecrementCounter(key string, amount int64) (bool, error)

DecrementCounter decreases the current count by the given nonnegative integer amount. The Counter Will not go below 0. Will execute the decrement operation against the current CRD value. Returns false if the count is at 0 (to the latest knowledge of the SDK), and no decrement will occur.

func (*Alpha) GetConnectedPlayers ¶ added in v1.6.0

func (a *Alpha) GetConnectedPlayers() ([]string, error)

GetConnectedPlayers returns the list of the currently connected player ids. This is always accurate, even if the value hasn’t been updated to the GameServer status yet.

func (*Alpha) GetCounterCapacity ¶ added in v1.35.0

func (a *Alpha) GetCounterCapacity(key string) (int64, error)

GetCounterCapacity returns the Capacity for a Counter, given the Counter's key (name). Will error if the key was not predefined in the GameServer resource on creation.

func (*Alpha) GetCounterCount ¶ added in v1.35.0

func (a *Alpha) GetCounterCount(key string) (int64, error)

GetCounterCount returns the Count for a Counter, given the Counter's key (name). Will error if the key was not predefined in the GameServer resource on creation.

func (*Alpha) GetPlayerCapacity ¶ added in v1.5.0

func (a *Alpha) GetPlayerCapacity() (int64, error)

GetPlayerCapacity gets the last player capacity that was set through the SDK. If the player capacity is set from outside the SDK, use SDK.GameServer() instead.

func (*Alpha) GetPlayerCount ¶ added in v1.6.0

func (a *Alpha) GetPlayerCount() (int64, error)

GetPlayerCount returns the current player count.

func (*Alpha) IncrementCounter ¶ added in v1.35.0

func (a *Alpha) IncrementCounter(key string, amount int64) (bool, error)

IncrementCounter increases a counter by the given nonnegative integer amount. Will execute the increment operation against the current CRD value. Will max at max(int64). Will error if the key was not predefined in the GameServer resource on creation. Returns false if the count is at the current capacity (to the latest knowledge of the SDK), and no increment will occur.

Note: A potential race condition here is that if count values are set from both the SDK and through the K8s API (Allocation or otherwise), since the SDK append operation back to the CRD value is batched asynchronous any value incremented past the capacity will be silently truncated.

func (*Alpha) IsPlayerConnected ¶ added in v1.6.0

func (a *Alpha) IsPlayerConnected(id string) (bool, error)

IsPlayerConnected returns if the playerID is currently connected to the GameServer. This is always accurate, even if the value hasn’t been updated to the GameServer status yet.

func (*Alpha) PlayerConnect ¶ added in v1.6.0

func (a *Alpha) PlayerConnect(id string) (bool, error)

PlayerConnect increases the SDK’s stored player count by one, and appends this playerID to status.players.id. Will return true and add the playerID to the list of playerIDs if the playerIDs was not already in the list of connected playerIDs.

func (*Alpha) PlayerDisconnect ¶ added in v1.6.0

func (a *Alpha) PlayerDisconnect(id string) (bool, error)

PlayerDisconnect Decreases the SDK’s stored player count by one, and removes the playerID from status.players.id. Will return true and remove the supplied playerID from the list of connected playerIDs if the playerID value exists within the list.

func (*Alpha) SetCounterCapacity ¶ added in v1.35.0

func (a *Alpha) SetCounterCapacity(key string, amount int64) (bool, error)

SetCounterCapacity sets the capacity for a given count. A capacity of 0 is no capacity.

func (*Alpha) SetCounterCount ¶ added in v1.35.0

func (a *Alpha) SetCounterCount(key string, amount int64) (bool, error)

SetCounterCount sets a count to the given value. Use with care, as this will overwrite any previous invocations’ value. Cannot be greater than Capacity.

func (*Alpha) SetPlayerCapacity ¶ added in v1.5.0

func (a *Alpha) SetPlayerCapacity(capacity int64) error

SetPlayerCapacity changes the player capacity to a new value.

func (*SDK) Allocate ¶ added in v0.10.0

func (s *SDK) Allocate() error

Allocate self marks this gameserver as Allocated.

func (*SDK) Alpha ¶ added in v1.5.0

func (s *SDK) Alpha() *Alpha

Alpha returns the Alpha SDK.

func (*SDK) GameServer ¶ added in v0.3.0

func (s *SDK) GameServer() (*sdk.GameServer, error)

GameServer retrieve the GameServer details.

func (*SDK) Health ¶

func (s *SDK) Health() error

Health sends a ping to the sidecar health check to indicate that this Game Server is healthy.

func (*SDK) Ready ¶

func (s *SDK) Ready() error

Ready marks the Game Server as ready to receive connections.

func (*SDK) Reserve ¶ added in v0.12.0

func (s *SDK) Reserve(d time.Duration) error

Reserve marks the Game Server as Reserved for a given duration, at which point it will return the GameServer to a Ready state. Do note, the smallest unit available in the time.Duration argument is a second.

func (*SDK) SetAnnotation ¶ added in v0.4.0

func (s *SDK) SetAnnotation(key, value string) error

SetAnnotation sets a metadata annotation on the `GameServer` with the prefix "agones.dev/sdk-".

func (*SDK) SetLabel ¶ added in v0.4.0

func (s *SDK) SetLabel(key, value string) error

SetLabel sets a metadata label on the `GameServer` with the prefix "agones.dev/sdk-".

func (*SDK) Shutdown ¶

func (*SDK) WatchGameServer ¶ added in v0.4.0

func (s *SDK) WatchGameServer(f GameServerCallback) error

WatchGameServer asynchronously calls the given GameServerCallback with the current GameServer configuration when the backing GameServer configuration is updated. This function can be called multiple times to add more than one GameServerCallback.
