Getting GameState property values after state is done updating
I have a GameState of properties. When I change a value, the property fires its own event. The event is being listened to by an observer script.
The observer script can assert when one value has changed. But when I make two consecutive changes to values, an event is fired before the GameState is done updating, and the observer can only see the value change for one property, not both.
How do I get the property values only after both value changes are complete?
GameState.cs
private int _x;
public event Action XChanged = () => { };
public int X
{
get => _x;
set
{
var x = _x;
_x = value;
if (value != x)
{
XChanged();
}
}
}
private int _y;
public event Action YChanged = () => { };
public int Y
{
get => _y;
set
{
var y = _y;
_y = value;
if (value != y)
{
YChanged();
}
}
}
Observer.cs
void StateValidator()
{
Assert.That(gameState.X, Is.EqualTo(1));
Assert.That(gameState.Y, Is.EqualTo(1));
}
gameStateService.State.XChanged += StateValidator;
gameStateService.State.YChanged += StateValidator;
shop.BuyXandY(1, 1); //buy 1x and 1y
Transaction.cs
public void BuyXandY(int xAmount, int yAmount)
{
GameStateService.Get().State.X += xAmount;
GameStateService.Get().State.Y += yAmount;
}
