Nested LocalizedString does not refresh

Hello,

I don’t have that much time to report a bug with a correct use case but I encounter a small annoyment with the nested LocalizedString system.

This contains a LocalizeStringEvent that should be updated each time _populationCount or _populationLevel change.

In my update function, I just do the following

_milestonePopulationCountLocalisedVariable.Value = nextMilestoneInfo._populationCount;
_milestonePopulationLevelLocalisedVariable.Value = nextMilestoneInfo._populationLevel;

those two variables are assigned in my Start function from a reference assigned in the editor “MilestoneText” in the image

[SerializeField] private LocalizeStringEvent _milestoneText;

private LocalizedString _nextMilestoneLocalizedString;
private IntVariable _milestonePopulationCountLocalisedVariable;
private IntVariable _milestonePopulationLevelLocalisedVariable;

private void Start()
{
    _nextMilestoneLocalizedString = _milestoneText.StringReference["_nextMilestone"] as LocalizedString;
    _milestonePopulationCountLocalisedVariable = _nextMilestoneLocalizedString["_populationCount"] as IntVariable;
    _milestonePopulationLevelLocalisedVariable = _nextMilestoneLocalizedString["_populationLevel"] as IntVariable;
}

The main problem is that changing the IntVariable(s) values does not update the Text value.

First “workaround”, I forced the LocalizeStringEvent to refresh _milestoneText.RefreshString();.

But, it comes with a pretty awful drawback, each time I exited the “play mode” it crashes with two call stacks

Exception: Reentering the Update method is not allowed.  This can happen when calling WaitForCompletion on an operation while inside of a callback.

So second workaround to avoid that and sorry it is ugly but it prevents the crash as my values are not changing that often.

if ((_milestonePopulationCountLocalisedVariable.Value != nextMilestoneInfo._populationCount) || (_milestonePopulationLevelLocalisedVariable.Value != nextMilestoneInfo._populationLevel))
{
    _milestonePopulationCountLocalisedVariable.Value = nextMilestoneInfo._populationCount;
    _milestonePopulationLevelLocalisedVariable.Value = nextMilestoneInfo._populationLevel;
    _milestoneText.RefreshString();
}

Sorry for the length of this post … but am I right in my way of doing and analysing? Is it a bug and if so, will it be fixed soon?

Im not aware of any bugs that fit this description, so if it is a bug it has not yet been reported.
Can you share an example project with the issue?

Thank you for your quick answer!

I dit try to make a repro as quick as possible.

In UpdateMilestoneComponent.cs I did comment some part of the code to go back to the initial code [that I suppose should work as is]

If you uncomment you reach the “post workaround” state with the crash when you exit “play mode”

    private void Update()
    {
        _milestonePopulationCountLocalisedVariable.Value = Time.frameCount;
        _milestonePopulationLevelLocalisedVariable.Value = Time.renderedFrameCount;

        // if (_milestoneText!= null)
        // {
        //     _milestoneText.RefreshString();
        // }
    }

My game if someone want to test :smile: Moons of Ardan on Steam

Thanks that shows the problem. I don’t have time to dig into it right now but I have created a bug report so it will be looked at.

The URL may not work at the moment, the system takes a little time to update.

I took a look at the project. It is indeed a bug, we were not triggering an update from nested strings.
A fix is in review now for the next release.
I have also fixed the MissingReferenceException bug.

Here is a small improvement to your code.

private void Update()
{
    PersistentVariablesSource.BeginUpdating();
    _milestonePopulationCountLocalisedVariable.Value = Time.frameCount;
    _milestonePopulationLevelLocalisedVariable.Value = Time.renderedFrameCount;
    PersistentVariablesSource.EndUpdating();
}

This ensures that only 1 refresh is made to the string instead of 1 per change.

Thank you so much … the update has been released from your side “1.0.4” but also, the “Updating” thing will help to improve some perfs
