Title: How to load a png file for View
Post by: jerryd on June 15, 2017, 03:59:19 am

SFML forum,
 I'm trying to figure out how to use View.

 I have read most of the documentation but I don't see
 how to load a png file that will be the View.  I tried to load
 it as I would a Texture but just got a compile error.

 sf::View view;
 if (!view.loadFromFile("C:/sprites/buildings.png"))
 { cout << " view Loading Error" << endl; system("pause"); }

 How do I do this?

Views can't render an image. If you want to use an image you need to use a texture and render it with a sprite or a vertex array.
And then adjust it to span across the whole view.

eXpl0it3r,

 Thanks for the reply.

 I loaded my background as a Texture and made it a sprite

 The window size is 600,600 so I used the command:
 sf::View view(sf::Vector2f(600, 600), sf::Vector2f(300, 300));

 At one point in my program I used the command:
 view.move(100, 0);
 but nothing happened.

 How do I tie the sprite to the view?  Or do I have this all wrong?

You need to set the view on the window before you draw the sprite.
I highly recommend you study the official tutorial on views: https://www.sfml-dev.org/tutorials/2.4/graphics-view.php
