How do you set the cursor position in SDL2?

Question

I want to be able to change the position of the cursor over my SDL2 window. I can't find anything in the documentation. Is there a way to do it?

Answer 1

Use the SDL_WarpMouseInWindow() function, it sets the mouse position in the SDL Window.

Demonstration:

auto* WIN = SDL_CreateWindow("text", 0, 0, Width, Height, SDL_WINDOW_RESIZABLE);
SDL_WarpMouseInWindow(WIN, 50, 50);/*sets mouse position to 50, 50 relative to the window */

Keep in mind, this invokes the SDL_MOUSEMOTION event so, if you're polling events, it will consider the change in mouse position as a mouse movement.
