How to update UI easily on variable change in MAUI
I need to update a lot of text and it is desirable to link the update to a change in variables, I tried to use binding, but as I understood it, it does not suit me
Swhy doesnt it suit you?
Sits the standard way of doing it
SI Googled and did not understand how to do this, as I understood, you can only bind two properties of different objects
Sidk what you mean different objects but you can bind any dependency property
Swhich is almost anything you need to bind
Si recommend reading up about the basics of mvvm first and taking this slower
SThe Model-View-ViewModel (MVVM) pattern enforces a separation between three software layers — the XAML user interface, called the view, the underlying data, called the model, and an intermediary between the view and the model, called the viewmodel.
SI will look

In this video, I am going to show you a way to use a static property on a control in your .NET MAUI projects.

Syou don't
Slike i said take this slow and learn everything from the beginning
Sdid you read the article i sent?
Sdo you understand what INotifyPropertyChanged is?
Sa bit
Syes
Swhat is it?
Sit notifies
Sit is used to make the user interface understand when it is being updated
Syeah it sends a notification with the name of the property that was changed
Snotification in the form of an event
Sand things like the ui can subscribe to the event
Sand it can know what properties in a class that implements INPC change and when
Sso all you need to do is bind to a property that sends a notification when its changed
Sthats all there is to it
Scan you give an example of code
Sthere are lots of examples here
Si see but how to use static vars
Slike i have a class with game logic and i have a static vars to use them anywhere
Syou dont you make an instance of the class representing the game state
Snooo i dont whant to
Sand how do i make it
Syou make it not static and create an instance
Sthen you can implement INPC and bind
Sbut how do i make it unique and accessable from other classes
Syou pass the instance you created to the other classes
Susually when constructing them
Sbut since you mentioned this is a game, then a singleton might be fine
Sor so ive heard about game dev
Swhat can you give me some articles or something
Sthere aren't any official docs
Sits pretty easy to look up
Si found only dependency injection
Soh i found
Syeah i made a singleton
SSdo you know what an interface is?
Si made it like check this
Sprivate void BindText()
{
Binding bind = new Binding();
bind.Source = MainGame.GetInstance();
bind.Path = "light";
lightText.SetBinding(Label.TextProperty, bind);
}
{
Binding bind = new Binding();
bind.Source = MainGame.GetInstance();
bind.Path = "light";
lightText.SetBinding(Label.TextProperty, bind);
}
Sand its working ye
Si really recommend learning the fundementals of c# on its own and then learning gui
