Input with winapi?
« on: October 24, 2009, 02:06:15 pm »
I have question:
Is possible to take mouse input via render window, when i'm using Winapi?
I'm currently doing it like this:
Code: [Select]

sprintf( Buffer, " MouseX: %d MouseY: %d", Render->GetInput().GetMouseX(), Render->GetInput().GetMouseY() );


And MouseX/Y is 0. Winapi changes smthing? I should take mouse from view or what?

Can you post a complete code? Why are you talking about Win API?

I don't know why you're using Win API directly, but if you do so then yes you can handle input directly as well.

What about sf::RenderWindow::GetEvent() or sf::RenderWindow::GetInput()? Input handling is explained in the tutorials, by the way...

Or what is exactly your problem?

If you give a complete source code I can try it and see what's wrong.

No it's not. I can't compile it (yes, I want to test it with a real compiler, not only with my eyes ;)).

And linker input:
Code: [Select]

sfml-system-s-d.lib sfml-main-d.lib sfml-window-s-d.lib sfml-graphics-s-d.lib

Project is much bigger i cut object etc classes, and other not important things(it's commercial and not only my project, so i can't paste here all).

This example works fine for me, the mouse coordinates are updated properly.

But u checking mouse coords from winapi or SFML? To see pos from SFML switch comments in fuction Display_FPS(this line with sprintf).

Ok I see.
It switched to SFML but now it doesn't compile (Mouse_X and Mouse_Y are not declared).

By the way, did you check the Win32 sample in the SDK? If this one works then you have a problem, if not then I have a problem ;)

It is!

int Mouse_X = Render->GetInput().GetMouseX(), Mouse_Y = Render->GetInput().GetMouseY();
