Constant SDL_HINT_MOUSE_RELATIVE_MODE_CENTER

pub const SDL_HINT_MOUSE_RELATIVE_MODE_CENTER: *const i8 = _; // {alloc39803<imm>: *const i8}
Available on crate feature dep_sdl3 only.
Expand description

A variable controlling whether relative mouse mode constrains the mouse to the center of the window.

Constraining to the center of the window works better for FPS games and when the application is running over RDP. Constraining to the whole window works better for 2D games and increases the chance that the mouse will be in the correct position when using high DPI mice.

The variable can be set to the following values:

  • “0”: Relative mouse mode constrains the mouse to the window.
  • “1”: Relative mouse mode constrains the mouse to the center of the window. (default)

This hint can be set anytime.

§Availability

This hint is available since SDL 3.2.0.
