    Class NullAchievementPlatformGateway

    The gateway installed when no platform is configured: always unavailable, accepts nothing, reports nothing. Lets the service run its full unlock path in the editor, in tests and in a build that ships to no storefront, without a null check at every call site.

    Type Description
    bool

    Methods

    ClearAsync(CancellationToken)

    Clears every achievement on the platform account. Intended for debugging and QA.

    Declaration
    public Task<bool> ClearAsync(CancellationToken cancellationToken)
    Parameters
    Type Name Description
    CancellationToken cancellationToken

    Token used to cancel the operation.

    Returns
    Type Description
    Task<bool>

    True when the platform accepted the clear; otherwise false.

    InitializeAsync(CancellationToken)

    Brings the platform session up. Returns whether the gateway is usable afterwards.

    Declaration
    public Task<bool> InitializeAsync(CancellationToken cancellationToken)
    Parameters
    Type Name Description
    CancellationToken cancellationToken

    Token used to cancel the operation.

    Returns
    Type Description
    Task<bool>

    QueryUnlockedAsync(CancellationToken)

    Reads back which achievements the platform account already has.

    Declaration
    public Task<PlatformUnlockQueryResult> QueryUnlockedAsync(CancellationToken cancellationToken)
    Parameters
    Type Name Description
    CancellationToken cancellationToken

    Token used to cancel the operation.

    Returns
    Type Description
    Task<PlatformUnlockQueryResult>
    Remarks

    The result keeps "the account has nothing unlocked" apart from "the platform could not be asked": a gateway that genuinely has no account to be wrong about (no SDK configured, no storefront targeted) answers Answered(IReadOnlyList<AchievementId>) with an empty list, while a gateway that talks to a real storefront answers Unreachable() when the client is down, the call throws, or it cannot otherwise vouch for the account it is reporting. Collapsing the two makes an unreachable storefront indistinguishable from an empty one, which is the exact invariant PlatformUnlockQueryResult exists to protect.

    SetProgressAsync(AchievementDefinition, long, long, CancellationToken)

    Reports progress towards a progressive achievement on the platform account.

    Declaration
    public Task<bool> SetProgressAsync(AchievementDefinition definition, long current, long target, CancellationToken cancellationToken)
    Parameters
    Type Name Description
    AchievementDefinition definition

    The achievement being advanced, carrying its platform identifiers.

    long current

    The current numerator.

    long target

    The numerator that unlocks the achievement.

    CancellationToken cancellationToken

    Token used to cancel the operation.

    Returns
    Type Description
    Task<bool>

    True when the platform accepted the progress; otherwise false.

    UnlockAsync(AchievementDefinition, CancellationToken)

    Marks an achievement as unlocked on the platform account.

    Declaration
    public Task<bool> UnlockAsync(AchievementDefinition definition, CancellationToken cancellationToken)
    Parameters
    Type Name Description
    AchievementDefinition definition

    The achievement to unlock, carrying its platform identifiers.

    CancellationToken cancellationToken
