Author Topic: mouse warping in sfml (Read 3365 times)

Hi,

I want to warp the mouse, so that the user can move the camera in FPS style.
in SDL there is a function SDL_WarpMoues() which does this. Is there such thing in SFML? Or how is it done in SFML?

Best regards,
Yours3!f

SFML 1.6 : sf::Window::SetCursorPosition
SFML 2 : See sf::Mouse (documentation not yet uptodate)

Depending on which version you use (1.6 or 2 ?) you can use sf::Window::SetCursorPosition or sf::Mouse::SetPosition.

I just checked the doxygen documentation for 2.0 on this site and realized that it wasn't up to date so I put the link to the source code. If you're using 2.0 version then I recommend you to build the documentation while compiling SFML. This way you have an local up-to-date version of the documentation.

Thanks, I'm going to build the docs definitely. I'm using version 2.

ok, I'm having a little bit of problem with this function.
It seems to warp my mouse to:
x coord: middle of the screen
y coord: middle of the screen - mouse height

that is for a 1280x720 window I get the mouse position 640, 340. I don't know if it is an SFML bug or I've done something wrong or it is just the windowing system (Kubuntu 11.04/ KDE), but it is clear that it warps my mouse to that location, because if I move the mouse in a way that in 33 ms (one frame) it moves more than 20-30 pixels then eventually my camera goes down as opposed to always going upwards because of that.

Did anyone have issues like that?

or how can I get the height of the cursor so that I can warp it to the correct position?

Best regards,

I think I solved the problem, I just needed to use
sf::Mouse::SetPosition(pos, window)
instead of
sf::Mouse::SetPosition(pos)

where window was the main window I created.
It seems to set the cursor position to the right location now.
