Action points not updating after pressing play

[tudor129]

Hello,

I am not sure why the world UI action points are not getting updated after I press play, they update correctly for all the units only after I spend the first point.

public class UnitWorldUI : MonoBehaviour
{
   [SerializeField] TextMeshProUGUI _actionPointsText;
   [SerializeField] Unit _unit;


   void Start()
   {
      Unit.OnAnyActionPointsChanged += Unit_OnAnyActionPointsChanged;
      UpdateActionPointsText();
   }
   void Unit_OnAnyActionPointsChanged(object sender, EventArgs e)
   {
      Unit unit = sender as Unit;
      Debug.Log($"{unit}'s action points have changed.");
      UpdateActionPointsText();
   }

   void UpdateActionPointsText()
   {
      _actionPointsText.text = _unit.GetActionPoints().ToString();
      Debug.Log("Points have been updated");
   }
}

The debug does, however, show up in the console.

What you are experiencing is a race condition. Your UnitWorldUI’s Start() is firing before the unit is initializing it’s ActionPoints.

Most likely, you’re initializing the Action Points the first time (likely in Start()) without calling OnAnyActionPointsChanged.

Indeed! I added a 0.1 second coroutine in the start method and it solved my issue. Thank you for the answer!
