Good Day Everyone!,

I am trying to learn Ogre 3D from the Samples. I wanted hide the OS mouse cursor and capture the mouse to be inside the game similar to the Sample Browser.

I tried to find cursor related codes inside the Samples directory but I couldn't find any clues. I only see Tray related show/hide cursor but it does not hide the native cursor.

I would guess it has to do with this function:

Code: Select all

void ApplicationContextSDL::setWindowGrab(NativeWindowType* win, bool _grab)
{
    SDL_bool grab = SDL_bool(_grab);

SDL_SetWindowGrab(win, grab);
#if OGRE_PLATFORM != OGRE_PLATFORM_APPLE
    // osx workaround: mouse motion events are gone otherwise
    SDL_SetRelativeMouseMode(grab);
#else
    SDL_ShowCursor(!grab);
#endif
}

Sorry for the late reply. I got so busy with work .

I tried this and seemed to work fine.

Code: Select all

SDL_SetRelativeMouseMode(SDL_TRUE);

Are the directives necessary? Does SDL not handle the cross platform feature in this case?

If someone specifically coded that, they must have had a reason to do so.
The comment in that function also explains why.

If you have a mac and a PC and be able to test it, you can check if it is needed or not.
