Can we carete xxx.asset (FSM) file in scripting level?

[mchoi]

Hi all,

We consider to deep copy FSM and BT file including nested FSM and BT. Any idea?

Because of we actually want to deep copy of FSM file including Nested FSM files. so I though that there are 2 option I do,
1. Copy FSM and BT files and attach proper Nested xxx.asset (FSM file).
2. Deep copy of FSM file including nested FSM or BT files.

Thanks.

Hello,

Do you mean creating a duplicate of a root asset graph along with duplicates of all sub-graphs instead of references to them?
If so, here is a NON tested way to do so recursively that should work. Commented code following:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

public Graph DeepCopy(Graph original){   //create a duplicate asset of provided original. Maybe show file selection dialog? var copy = //your editor method to do so, like AssetDatabase.CreateAsset.   //make use of IGraphAssignable interface to find nodes that represent a sub-graph. foreach(var subGraphNode in copy.allNodes.OfType<IGraphAssignable>()){ if (subGraphNode.nestedGraph != null){   //duplicate the existing sub-graph and assign the copy to node. subGraphNode.nestedGraph = DeepCopy(subGraphNode.nestedGraph);; } } return copy; }

Let me know if that works for you, or if you need any further help with this, and if that was indeed what you were after.
Thanks.

Yeah, I mean that deep copy as you post.
I wish that feature will be in next release of NodeCanvas.

Thanks.

Hello,
This has now been added in the “gear” context menu of a graph asset. If you want, you can add this now manually as well, by opening Editor_Graph.cs file and adding this code at the end:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

[ContextMenu("Deep Duplicate")] public void DeepDuplicate(){ if (EditorUtility.DisplayDialog("Deep Duplicate", "This will create a deep duplicate of this graph asset along with it's subgraphs. Continue?", "Yes", "No")){ DeepCopy(this); } }   ///Make a deep copy of provided graph asset along with it's sub-graphs. static Graph DeepCopy(Graph root){ if (root == null){ return null; }   var path = EditorUtility.SaveFilePanelInProject ("Duplicate of " + root.name, root.name + "_duplicate.asset", "asset", ""); if (string.IsNullOrEmpty(path)){ return null; }   var copy = (Graph)ScriptableObject.CreateInstance(root.GetType()); AssetDatabase.CreateAsset(copy, path); EditorUtility.CopySerialized(root, copy);   //make use of IGraphAssignable interface to find nodes that represent a sub-graph. foreach(var subGraphNode in copy.allNodes.OfType<IGraphAssignable>()){ if (subGraphNode.nestedGraph != null){ //duplicate the existing sub-graph and assign the copy to node. subGraphNode.nestedGraph = DeepCopy(subGraphNode.nestedGraph);; } }   copy.Validate(); AssetDatabase.SaveAssets(); return copy; }

Cheers!
