Hello,

I have a dialogue system number variable called "Money" that I want to display on my UI, however it doesn't update according to what's entered in the inspector.

Would anyone know what I'm missing here?

Code: Select all

using PixelCrushers.DialogueSystem;

public class Money : MonoBehaviour
{
    public int moneyAmount;
    public TextMeshProUGUI moneyDisplay;

    void Update()
    {
        moneyDisplay.SetText(moneyAmount.ToString()); 
        UpdateMoneyVar();
    }

    public void UpdateMoneyVar()
    {
        int moneyAmount = DialogueLua.GetVariable("Money").asInt;
    }

I have registered 'UpdateMoneyVar()' with Lua in case that helps.

Thank you!

Hi,

I see you also have a C# variable named moneyAmount. I recommend having only one variable to track money -- either your C# variable moneyAmount, or your Dialogue System Number variable Money.

If you use the DS variable, then in C# use DialogueLua.GetVariable() and SetVariable() to access it. Example:

Code: Select all

void Update()
{
    moneyDisplay.text = DialogueLua.GetVariable("Money").asInt;
}

Side note: Setting TextMeshProUGUI text in Update() is fine for an initial "get it working" pass. But I recommend changing it slightly in the future. When you set TextMeshProUGUI text, it rebuilds the entire mesh that visually represents the text. This is a somewhat heavy process that you don't need to do every frame. Instead, you can do it only when the Money variable changes. See Monitor Variable Changes.

Hi Tony,

Thanks for the help.
I just had to do add '.ToString()' at the end to get it to work as text.

One last question though, how can I increase the value of a number DS variable in script?

Thank you!

Hi,

Code: Select all

int money = DialogueLua.GetVariable("Money").asInt;
DialogueLua.SetVariable("Money", money + 1);
DialogueManager.SendUpdateTracker(); // Add this line if you need to update the quest tracker HUD.
