UI Bar connected to Variables

Hi there,
I would like to connect a UI bar to a variable I increase through the dialogue system.
Is there a way to do it and show it through a simple animation?
Many thanks,
Alberto

Yes. Please see:
Monitor Lua Variable Changes. For example, say you have a variable named Score. You can monitor it like this:
Code: Select all
public Slider scoreSlider; //<-- Assign in inspector.
void Start()
{
Language.Lua.Assignment.MonitoredVariables.Add("Score");
Language.Lua.Assignment.VariableChanged += OnVariableChanged;
}
void OnVariableChanged(string variableName, object variableValue)
{
if (variableName == "Score") scoreSlider.value = (float)variableValue;
}

Hi there, thanks again for the reply.
I'm getting this error.
I've created a custom function and called it "Confidence".
What am I doing wrong?
Sorry but I'm not that great at programming.

Hi,
A function named "Confidence" and a variable named "Confidence" are two separate things. Is there one in specific that you'd like to use?
What DS version are you using? You may need to update to get access to MonitoredVariables and VariableChanged.

I would like to use a Confidence Variable.
I've updated the dialogue system and is not giving me errors anymore.
I've created a slider bar with fill, connected the script to the slider and assigned it to the script.
I then created a Confidence variable on the dialogue system and assigned Variable["Confidence"] = 0.5 through the script section in one of my dialogues.
The slider bar is in a canvas outside the dialogue UI.
Unfortunately, it doesn't seem to increase the slider when I run the dialogue.
What am I doing wrong?

Hi,
What is your script?
It should look something like:
Code: Select all
using UnityEngine;
using UnityEngine.UI;
using PixelCrushers.DialogueSystem;
public class Confidence_bar : MonoBehaviour
{
public Slider scoreSlider; //<-- Assign in inspector.
void Start()
{
Language.Lua.Assignment.MonitoredVariables.Add("Confidence");
Language.Lua.Assignment.VariableChanged += OnVariableChanged;
}
void OnVariableChanged(string variableName, object variableValue)
{
if (variableName == "Confidence") scoreSlider.value = (float)variableValue;
}
}

I was just missing "using PixelCrushers.DialogueSystem;".
For the rest, the script is the same and unfortunately, even including the missing bit, still doesn't show any changes in the slider.

Try adding a Debug.Log to check if the variable changed method is being called:
Code: Select all
void OnVariableChanged(string variableName, object variableValue)
{
Debug.Log($"{variableName} changed to {variableValue}");
if (variableName == "Confidence") scoreSlider.value = (float)variableValue;
}

Nope, the value is not increasing.
The debug is not catching any change in the Confidence variable.

Hi,
Does the Debug.Log line appear at all in the Console?
