Syntax

protected IReadOnlyList<ICoroutine> GetAllCoroutines ()

Returns

A list containing all running or waiting coroutines.

Remarks

 

Requirements

Namespace: Sansar.Script
Assembly: Sansar.Script (in Sansar.Script.dll)
Assembly Versions: 1.0.0.0

GetCoroutineCount Method

The total number of coroutines running on this script.

Syntax

protected int GetCoroutineCount ()

Returns

The total number of coroutines running on this script.

Remarks

Includes currently active and waiting coroutines, but not killed coroutines. A new list is created every time it is called with the coroutines at the time of the call. It is possible for coroutines to finish while iterating on the list which will not remove them from the list. Any finished coroutines still in the list will have IsAlive == false.

Requirements

Namespace: Sansar.Script
Assembly: Sansar.Script (in Sansar.Script.dll)
Assembly Versions: 1.0.0.0

Init Method

Init() is called after all interfaces have been initialized.

Syntax

[Sansar.Script.NonReflective]
public abstract void Init ()

Remarks

Override Init() to set up script subscriptions and callbacks. Any members set before Init is called (such as in a script constructor) may be overwritten before Init is called.

Requirements

Namespace: Sansar.Script
Assembly: Sansar.Script (in Sansar.Script.dll)
Assembly Versions: 1.0.0.0

Lock Method

Use to create a critical section with a using statement, ensuring that no other coroutines or scripts (via Reflective) may enter this code section while one coroutine or script is in it.

Syntax

protected ScriptBase.ScopedLock Lock (object Token)

See Also

Parameters

Token
The object controlling the lock. Recommended to be a private object member.

Returns

A ScopedLock that holds the lock and will release it in IDisposable.Dispose.

Exceptions

Type Reason
ArgumentNullException Thrown if Token is null.

Remarks

Use with using to create a critical section. If a lock is already held on Token by a different coroutine then this coroutine will wait for the lock to be released before entering the critical section. Lock is conceptually similar to the lock keyword.

Example

C# Example
            private object BalanceLock = new Object();
            int Balance = 100;
            bool Spend(int value)
            {
                using (Lock(BalanceLock))
                {
                    if (Balance > value)
                    {
                        Balance -= value;
                        return true;
                    }
                    return false;

Remarks

It is highly recommended to use ScriptBase.Lock(object) instead. This is for advanced use only and can easily create deadlocks that stop scripts from working. Can not be used to release a lock not currently held by this coroutine.

Example

C# Example
            private object BalanceLock = new Object();
            int Balance = 100;
            bool Spend(int value)
            {
                WaitForLock(BalanceLock);
                bool success = false;
                if (Balance > value)
                {
                    Balance -= value;
                    success = true;
                }
                ReleaseLock(BalanceLock);
                // Note that any early exit between WaitForLock and ReleaseLock fail to release the lock, creating a deadlock the next time this method is called.
                // For this reason it is highly recommended to instead do: using (Lock(BalanceLock))
                return success;
            }

Requirements

Namespace: Sansar.Script
Assembly: Sansar.Script (in Sansar.Script.dll)

Event handlers are useful when there is a well contained bit of code which can get most or all of its state from the Sansar.Script.EventData it receives. In this example, a separate data structure is needed to keep track of the name and join time for each agent since there could be multiple agents in the scene.

    // Wait for new users and start a new coroutine to time them.
    private void TrackNewUsers()
    {
        // This coroutine will run for the lifetime of the script.
        while (true)
        {
            // Block until an add user event happens
            UserData data = (UserData)WaitFor(ScenePrivate.User.Subscribe, User.AddUser, SessionId.Invalid);

            // Start a new coroutine to track the new user
            // Each coroutine will run cooperatively with the others, this script, and other scripts in the system
            StartCoroutine(TrackUser, data.User);
        }
    }

    // There will be one instance of this coroutine per active user in the scene
    private void TrackUser(SessionId userId)
    {
        // Track joined time
        long joined = Stopwatch.GetTimestamp();

        // Lookup the name of the agent. This is looked up now since the agent cannot be retrieved after they
        // leave the scene.
        string name = ScenePrivate.FindAgent(userId).AgentInfo.Name;

        // Block until the agent leaves the scene
        WaitFor(ScenePrivate.User.Subscribe, User.RemoveUser, userId);

        // Calculate elapsed time and report.
        TimeSpan elapsed = TimeSpan.FromTicks(Stopwatch.GetTimestamp()-joined);
        ScenePrivate.Chat.MessageAllUsers(string.Format("{0} was present for {0} seconds", name, elapsed.TotalSeconds));
    }
}

While the amount of code is approximately the same for each, the coroutine version does not require access to any member data, simplifying the tracking by moving all the required information to stack variables.

WaitForLock Method

WaitFor and take a lock on Token

Syntax

protected void WaitForLock (object Token)

See Also

Parameters

Token
The object controlling the lock. Recommended to be a private object member.

Exceptions

Type Reason
ArgumentNullException Thrown if Token is null.

Remarks

It is highly recommended to use ScriptBase.Lock(object) instead. This is for advanced use only and can easily create deadlocks that stop scripts from working. If not paired with ScriptBase.ReleaseLock(object) will create a deadlock preventing this code from being entered.

Example

C# Example
            private object BalanceLock = new Object();
            int Balance = 100;
            bool Spend(int value)
            {
                WaitForLock(BalanceLock);
                bool success = false;
                if (Balance > value)
                {
                    Balance -= value;
                    success = true;
                }
                ReleaseLock(BalanceLock);
                // Note that any early exit between WaitForLock and ReleaseLock fail to release the lock, creating a deadlock the next time this method is called.
                // For this reason it is highly recommended to instead do: using (Lock(BalanceLock))
                return success;
            }

Requirements

Namespace: Sansar.Script
Assembly: Sansar.Script (in Sansar.Script.dll)
Assembly Versions: 1.0.0.0
