(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_HINT_MOUSE_RELATIVE_MODE_CENTER

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

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_MOUSE_RELATIVE_MODE_CENTER "SDL_MOUSE_RELATIVE_MODE_CENTER"

Remarks

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.

Version

This hint is available since SDL 3.1.3.
