Round Variable in Dialogue Text

[OneManOnMars]

Hey hey,

is there a way to round the variables in the dialogue text?


I would like to provide record times here and it would be cool to only show 2 digits after the point.

Currently, it looks like this:


I did try to round the number before setting it like this:

Code: Select all

public void StopTimer()
    {
        if (isTiming)
        {
            FinishPaticle.Play();
            elapsedTime = Time.time - startTime;
            float roundedTime = Mathf.Round(elapsedTime * 100) / 100;
            isTiming = false;

            // Vergleich mit der Record-Zeit
            if (elapsedTime < record || record == 0)
            {
                Debug.Log(elapsedTime);
                DialogueLua.SetVariable(DSRecordVariable, roundedTime);

Thank you very much.

Ok, I did some more digging and strangely the variable seems to be stored right. But when I display it like shown above it is different.
Please look here:

Hi,

That's floating point numbers for you. Their values can drift slightly. The Unity editor may be doing a bit of rounding when showing the value in the Dialogue Editor's Watches section, which just calls EditorGUILayout.FloatField().

If you're doing math in C#, use Mathf.RoundToInt():

Code: Select all

DialogueLua.SetVariable(DSRecordVariable, Mathf.RoundToInt(elapsedTime));

Then it should show correctly when you use [var=variable] in Dialogue Text.

If you're doing it entirely in Lua, there's no rounding function, but you can use math.floor():

Code: Select all

Level 1: [[lua(math.floor(0.5 + Variable["RecordTC00"]))]

Thank you Tony for the fast reply.

Using floor was no real option since I wanted 2 decimal numbers.
However, in the end, I figured that displaying only seconds is not the best option anyway. So, I decided to store two variables. One of them as a string in the correct format.

This looks like this, just in case anyone is interested in it.

Code: Select all

 public void StopTimer()
    {
        if (isTiming)
        {
            FinishPaticle.Play();
            elapsedTime = Time.time - startTime;
            float roundedTime = Mathf.RoundToInt(elapsedTime * 100) / 100f;
            isTiming = false;

            // Compare Time
            if (elapsedTime < record || record == 0)
            {
                Debug.Log(roundedTime);
                DialogueLua.SetVariable(DSRecordVariable, roundedTime);
                if (timerText != null)
                {
                    NewRecordText.text = FormatTime(roundedTime);
                    NewRecordUI.SetActive(true);
                }
                DialogueLua.SetVariable(DSRecordVariable + "_String", FormatTime(roundedTime));
            }
           
            else
            {
                if (timerText != null)
                {
                    timerText.text = FormatTime(roundedTime);
                    RecordText.text = FormatTime(record);
                    RunTimerUI.SetActive(true);

                }
            }

            // display time in UI component
            
        }
        else
        {
            Debug.Log("Zeitmessung ist nicht gestartet.");
        }
    }
    // Helper function to format to time format
        private string FormatTime(float timeInSeconds)
    {
        int minutes = Mathf.FloorToInt(timeInSeconds / 60f);
        int seconds = Mathf.FloorToInt(timeInSeconds % 60f);
        int milliseconds = Mathf.FloorToInt((timeInSeconds * 100f) % 100f);
        return string.Format("{0:00}:{1:00}:{2:00}", minutes, seconds, milliseconds);
    }
