Stats

Talo stats let you track individual player data as well as aggregated global data - like how many items have been crafted or how many deaths a player has.

To create a stat, head over to the dashboard, visit the stats page and create your first stat. Take note of the Internal name as this is how you'll be referring to your stat.

Getting stats

You can list all available stats using Talo.Stats.GetStats(). This will return all the constraint data defined in the dashboard like the defaultValue, maxChange and maxValue. This will also return the global values for global stats:

var res = await Talo.Stats.GetStats();
var internalNames = res.Length > 0 ? string.Join(", ", res.Select((item) => item.internalName)) : "no stats";
// e.g. Stats: gold-collected, health-healed, deaths
Debug.Log($"Stats: {internalNames}");

Fetching individual stats

If you already have the internal name of a stat, you can use Talo.Stats.Find() and pass in the internal name to return data for a single stat.

Tracking stats

You can track a stat using the Stats API Track() function which takes your stat's internalName and the amount to change the stat by (default 1.0f):

PlayerDeathController.cs

public void OnDeath()
{
	Talo.Stats.Track('deaths')
}

PlayerPotionController.cs

private float health;

public void OnHeal(Potion potion)
{
	health += potion.amount
	Talo.Stats.Track('health-healed', potion.amount)
}

Stat values

After updating a stat using Track(), you can check the updated value for the player stat and global stat:

var res = await Talo.Stats.Track('gold-collected', 104);
Debug.Log($"{res.playerStat.value}, {stat.playerStat.stat.globalValue}")

Stat history

You can fetch a history of updates to a stat for the current player using Talo.Stats.GetHistory(). These results are paginated and can be filtered by specific start and end dates too:

private async void FetchHistory()
{
	try
	{
		var res = await Talo.Stats.GetHistory(statInternalName);

		// e.g. "gold-collected changed by 100, 46, 82, 19, 104"
		Debug.Log($"{statInternalName} changed by: {string.Join(", ", res.history.Select((item) => item.change))}");
	}
	catch (Exception err)
	{
		Debug.LogError(err.Message);
		throw err;
	}
}

Global stat history

For global stats, you can also fetch a history of updates from all players using Talo.Stats.GetGlobalHistory(). This API is similar to the player stat history except that it is filterable by individual players and it returns metrics about the stat during the filtered time period:

private async void FetchGlobalHistory()
{
	try
	{
		var res = await Talo.Stats.GetGlobalHistory(statInternalName);
		var globalMetrics = res.globalValue;
		var playerMetrics = res.playerValue;

		Debug.Log(
			$"Min: {globalMetrics.minValue}, " +
			$"max: {globalMetrics.maxValue}, " +
			$"median: {globalMetrics.medianValue}, " +
			$"average: {globalMetrics.averageValue}, " +
			$"average change: {globalMetrics.averageChange}, " +
			$"average player value: {playerMetrics.averageValue}"
		);
	}
	catch (Exception err)
	{
		Debug.LogError(err.Message); // e.g. stat isn't global
		throw err;
	}
}
