Move 2D-Camera with mouse
« on: April 12, 2015, 02:46:28 pm »
Hello!

I am new here in the forum and a SFML-beginner and wanted to ask how to move the view-camera with the mouse (for example if you press and hold the right mouse button and move it to also move the camera)?

I tried to get the current mouse position with this code:
sf::Vector2i Mouse = sf::Mouse::getPosition(window);
 

But it's an integer-vector and the view.move command for example requires two float-values.

So how is it possible?

Thank you very much!

try doing something like this:

sf::Vector2f CurrentMousePosition = sf::Mouse::getPosition(YourWindow);
 

or try converting it in 'view.move' static_cast<float>(Variable)

Please, explain it better!!!!
And i will help you

Thanks for your reply!!

It seems that it works now if I use this code:
...
sf::Vector2i Mouse = sf::Mouse::getPosition(window);
...
//Game-Loop
view1.setCenter(Mouse.x, Mouse.y);
 

Here it seems to work although the setCenter-command requires a float-vector.

and also:

view1.setCenter(static_cast<float>(Mouse.x), static_cast<float>(Mouse.y));
but it is complicated....

You're welcome!

If you want to convert pixel coordinates to world coordinates, don't just cast them, but use sf::RenderWindow::mapPixelToCoords().
