Change the View without having the source instance?

[lapayo]

Hello, I have a little poblem with zooming and moving the view.

Normally I would do the following:

Code: [Select]

sf::View CustomView;
App.SetView(CustomView);
CustomView.Zoom(1.5f);

But what if the current Class don´t knows the view?
Do i have to inject it?

I looked into RenderWindow and found the following:
GetView()
So I tried the following:

Code: [Select]

App->GetView().Zoom(1.5f);
But this gave me an error.
I also tried some casting:

Code: [Select]

((sf::View) App->GetView()).Zoom(1.5f);

This doesn´t produce a compiler error, but at runtime nothing happens.

Is there a way to get and change the current View?

Thanks in Advance,

Not in SFML 1.6, because sf::View instances had to be managed externally (so basically, SFML doesn't allow you to edit "someone else"'s view if you don't know "someone else" directly).

But in SFML 2 views are handled by copy, so you can get and set the current view from any location in the code.

Hey, thanks for your reply.
But how can I change it in SFML 2?
I have setup SFML 2 now, but I don´t get the view changed.

I tried the following:

Code: [Select]

((sf::View) App->GetView()).Zoom(1.5f);

//way number 2
sf::View View(App->GetView());
View.Zoom(1.5f);
App->SetView(View);

But boths methods are not working


EDIT: It was my fault.
The second method is working. But my main-loop was resetting it always

Thanks for your help
