i wanna change the cursor in my sdl project, but i am not quite sure how.

the simplest way i have figured out is to use SDL_ShowCursor (0); (i think thats the name of the function) to hide the cursor, and then i'd blit the cursor image to the screen at the invisible cursors current x and y coordinates.

is there any easier way to do this?

Here, this looks useful: SDL_CreateCursor - SDL Wiki'

Oh, and this: SDL_SetCursor - SDL Wiki'

Those functions should do it, but for a more DIY option:
1. Use the unit32 flag when creating your window to hide the cursor.
2. Create a class with an x and y variable, a function that blits the image to the screen at the x and y variables and one that updates the x and y to the event.motion.x/y variable.
3. When mouse motion is detected (in your event loop) call the updating function.
4. Every frame call the blitting function.

ok thanks.

I'd assume that the SDL functions would use OS API functions to do it though so it would have better performance.
