[NodeCanvas] OnLoaded for initialization

[leanon00Participant]

Hello! Maybe I am wrong but there is no function for initialization that is called once when the graph is loaded for “heavy” stuff..

As OnInit() is called once first time the node is active this can produce the needed allocations or heavy stuff in the middle of the game which is not optimal.

Graph.cs

1 2 3 4 5 6 7

virtual protected void OnGraphInitialize()         {             // Add OnLoaded callback for tasks.             foreach (var task in allTasks)                 task.OnLoaded();         }

Task.cs

1 2 3 4 5 6 7 8 9 10 11

virtual protected string OnInit() { return null; }           /// <summary>This is called once when the graph is loaded.</summary>         virtual public void OnLoaded() { }   ///<summary>Called once the first time task is created</summary> virtual public void OnCreate(ITaskSystem ownerSystem) { } ///<summary>Called when the task is created, duplicated or otherwise needs validation.</summary> virtual public void OnValidate(ITaskSystem ownerSystem) { }

Fsm.cs

1 2 3 4 5 6 7 8 9 10 11 12 13

protected override void OnGraphInitialize() {             //we may be loading in async             ThreadSafeInitCall(GatherCallbackReceivers);             updatableNodes = new List<IUpdatable>();             for ( var i = 0; i < allNodes.Count; i++ ) {                 if ( allNodes[i] is IUpdatable ) {                     updatableNodes.Add((IUpdatable)allNodes[i]);                 }             }               base.OnGraphInitialize(); <-- here         }

Usage.cs

1 2 3 4 5 6 7 8 9

public override void OnLoaded()         {             base.OnLoaded();             if (bigDictionary == null)             {                 bigDictionary = new BigDictionary(500);             }         }

Hello!

Indeed there is no call in Tasks for when the graph is initialized. I will add something for this in a future update though.
Thank you for your suggestion 🙂
