How can I edit the value of a costum script variable with dialogue sequences.

[gdbaradit]

This question might have been answered before, but I couldn't find anything related.

I wish to be able to change the value of a variable inside of a script of mine depending on the responses the player gives.

A simple example:

Q: Are you a boy or a girl?

R: Boy.

then inside a "character_attributes" script change the gender to a "boy" string, or a "boy" bool to "true" etc...

What should I learn or study to do that with dialogue system?

Thanks in advanced!

Hi,

Add methods to your script to get and set the gender variable. For example:

Code: Select all

public class PlayerGender : MonoBehaviour
{
    public string gender = "unspecified";
    
    public void SetGender(string value) { gender = value; }
    
    public string GetGender() { return gender; }
}

Then make these methods available to the Dialogue System's Lua environment by registering them as Lua functions. Grabbing some of the code from Templates / Scripts / TemplateCustomLua.cs, you could expand the script like this:

Code: Select all

using UnityEngine;
using PixelCrushers.DialogueSystem;

public class PlayerGender : MonoBehaviour
{
    public string gender = "unspecified";

    void OnEnable()
    {
        Lua.RegisterFunction("SetGender", this, SymbolExtensions.GetMethodInfo(() => SetGender(string.Empty)));
        Lua.RegisterFunction("GetGender", this, SymbolExtensions.GetMethodInfo(() => GetGender()));
    }

    void OnDisable()
    {
        Lua.UnregisterFunction("SetGender");
        Lua.UnregisterFunction("GetGender");
    }

    public void SetGender(string value) { gender = value; }

    public string GetGender() { return gender; }
}

Then you can use GetGender() and SetGender() in your conversations' Conditions and Script fields.
