Adding Playmaker's variables in editmode from code.

[DiaG]

Hello. I'm try to add PM variable from code in CustomActionEditor.
I did not find the interface to add or remove some variables, only the get/set methods in Fsm.Variables.(FsmType). However, using set-method remove all assignments of variables. I use it to load the variable names and their values ​​from the xml to display dialogs.
While I treat the following ways: one button compares the existing variables, and tells what variables are present in the xml, but not in the variables; the other button fills exist variables from the file; the third (with a warning that all assignments of type String will be lost) creates an array and sets Fsm.Variables.StringVariables.
Is it possible to add / remove variables from the code without losing assignments?

Hi,

 I am not sure what you mean by "assignment". Do you have a concret example or a screencast? then I'll be able to look at this properly.

bye,

Jean

Sorry for bad english. I do not know how to accurately translate. I have code:

Code: [Select]

[CustomActionEditor(typeof(LoadStringsFromXML))]
public class MyCustomEditor : CustomActionEditor
{
    ...
    public override bool OnGUI()
    {
        var action = target as LoadStringsFromXML;
        ...
        List<FsmString> newList = new List<FsmString>();
...
        action.Fsm.Variables.StringVariables = newList.ToArray();
        ...
    }
}
Thereafter all field (type of FsmString) in all actions are set to None (for current FSM). 
The screenshot shows state before and after this action.

Yeah, that code would replace all the string variables used by the FSM.

You could add the new variables to the array using ArrayUtility.AddRange():

To be honest, this is not a use case that's been tested with custom editors, so let me know how this goes and we can work through any issues...

You could add the new variables to the array using ArrayUtility.AddRange():

Thank you. I have tried to do so, but AddRange<T>(ref T[] array, T[] items) have "ref" modifier, and StringVariables is a property, not field. As result I get: "A property or indexer `HutongGames.PlayMaker.FsmVariables.StringVariables' may not be passed as `ref' or `out' parameter"

[Alex Chouls]

Hmmm, you could write your own ArrayUtility:

Code: [Select]


public static T[] Add<T>(T[] array, T item)
{
var list = new List<T>(array) {item};
return list.ToArray();
}

public static T[] AddRange<T>(T[] array, T[] items)
{
var list = new List<T>(array);
        list.AddRange(items);
return list.ToArray();
}
