Defined in SDL_hints.h




When this hint is set, any SDL will emulate mouse warps using relative mouse mode. This is required for some older games (such as Source engine games), which warp the mouse to the centre of the screen rather than using relative mouse motion. Note that relative mouse mode may have different mouse acceleration behaviour than pointer warps.

This variable can be set to the following values:

If not set, this is automatically enabled unless an application uses relative mouse mode directly.
