(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_GetMouseState

Retrieve the current state of the mouse.

Header File

Syntax

Uint32 SDL_GetMouseState(float *x, float *y);

Function Parameters

x	the x coordinate of the mouse cursor position relative to the focus window
y	the y coordinate of the mouse cursor position relative to the focus window

Return Value

Returns a 32-bit button bitmask of the current button state.

Remarks

The current button state is returned as a button bitmask, which can be tested using the SDL_BUTTON(X) macro (where X is generally 1 for the left, 2 for middle, 3 for the right button), and x and y are set to the mouse cursor position relative to the focus window. You can pass NULL for either x or y.

Version

This function is available since SDL 3.0.0.

Code Examples

float x, y;
Uint32 buttons;

SDL_PumpEvents();  // make sure we have the latest mouse state.

buttons = SDL_GetMouseState(&x, &y);

SDL_Log("Mouse cursor is at %f, %f", x, y);
if ((buttons & SDL_BUTTON_LMASK) != 0) {
    SDL_Log("Mouse Button 1 (left) is pressed.");
}
