Edit ExternalBehaviorTree variables from a custom inspector

[Dorcan]

Hello !

We've integrated Behavior Designer in our game, and I wanted to integrate exposed variables of ExternalBehaviorTree inside our own custom inspector for our enemies. That way all variables for each enemies are centralized, making it easier to use for our game designer.


Our inspector with values from the external behavior tree


The external behavior tree

However, I couldn't figure out how to save the changes in the asset. They are saved in memory alright, but when reloading scripts or reopening the project, values are reverted.

Here's an extract from my code:

                    switch (type.Name)
                    {
                        case "Int32":
                            variableValue = EditorGUI.IntField(position, variable.Name, (int)variable.GetValue());
                            position.y += lineHeight;
                            break;

                        case "Single":
                            variableValue = EditorGUI.FloatField(position, variable.Name, (float)variable.GetValue());
                            position.y += lineHeight;
                            break;

                        case "Vector2":
                            variableValue = EditorGUI.Vector2Field(position, variable.Name, (Vector2)variable.GetValue());
                            position.y += lineHeight;
                            break;
                    }

                    externalBehaviorTree.SetVariableValue(variable.Name, variableValue);
                  
                    if (EditorGUI.EndChangeCheck())
                    {
                        EditorUtility.SetDirty(externalBehaviorTree);
                        AssetDatabase.SaveAssets();
                    }

I tried with externalBehaviorTree.SetBehaviorSource(...) but no luck.
Is there any public way to edit and save exernalBehaviorTree variables from an external editor ?

Thanks for your response, and thanks for this wonderful tool ! ?

Happy to hear that you're enjoying Behavior Designer! Here's a post that has a code snippet for serializing the tree:

Handling many mapped variables

Hi there! Is there a way to assign mapped variables programatically? I have a large amount (~50), and also want to interchange behavior trees. I feel like there might be a smarter way to do it, as creating and mapping shared variables is somewhat cumbersome. But I can't figure one out. The...

Awesome! Works perfectly.

Happy to hear that you're enjoying Behavior Designer!

I am! Also, going through the available source code helped me make some decisions about my own code as well, so... thanks !
