Hello everyone,
I would like to change the default cursor of my mouse, by a chart because I am doing the game duck hunt. I did some stuff but it does not work ...
Can you help me ?

"it does not work" is not a problem description. ;)

Hey luffy50660,

first of all, clear created "objects" and set it to NULL, to let dangling pointer no chance to act.

If i understand your problem right, you wanna use a custom mouse cursor picture, instead of the OS Cursor?

Code: [Select]
sfWindow_setMouseCursorVisible(window, sfFalse);
// Sets the OS Cursor invisible
...

sfSprite_setTexture(cursor, texture2, sfTrue);
// Sets your custom texture to the sprite
...

sfVector2i cursor_coord;
cursor_coord.x = 1280;
cursor_coord.y = 769;
sfMouse_setPosition(cursor_coord, window);
// Sets your invisible OS Mouse Cursor at application start to bottom right
// there is no sense in there
...

In your main loop, i dont find anything about update your cursor position.

------------------------------------

First set the Initial Position of Your Cursor Sprite and update it in your main loop.

I made some minimal running example.
Code: [Select]
#include <stdio.h>
#include <stdlib.h>
#include <SFML/Audio.h>
#include <SFML/Graphics.h>
#include <SFML/Window.h>
#include <SFML/System.h>

int main()
{
    // Variables
    sfVideoMode mode = {600, 600, 32};
    sfEvent EventLoop;
    sfRenderWindow *screen;
    sfSprite *Cursor_Sprite;
    sfTexture *Cursor_Texture;
    sfVector2f Cursor_Position;

    // Init Stuff
    screen = sfRenderWindow_create(mode, "Minimal Example", sfClose, NULL);

    Cursor_Texture = sfTexture_createFromFile("MouseCursor.png", sfFalse);
    Cursor_Sprite = sfSprite_create();

    // Check created Stuff
    if(screen == NULL || Cursor_Sprite == NULL || Cursor_Texture == NULL)
        return 0;

    // Get Initial Position
    Cursor_Position.x = sfMouse_getPosition(screen).x;
    Cursor_Position.y = sfMouse_getPosition(screen).y;

    // Set Texture to Sprite
    sfSprite_setTexture(Cursor_Sprite, Cursor_Texture, sfFalse);
    sfSprite_setPosition(Cursor_Sprite, Cursor_Position);

    // Set Windows Cursor invisible
    sfRenderWindow_setMouseCursorVisible(screen, sfFalse);

    // Main Loop
    while (sfRenderWindow_isOpen(screen))
    {
        // Proceed Events
        while (sfRenderWindow_pollEvent(screen, &EventLoop))
        {
            if(EventLoop.type == sfEvtClosed)
                sfRenderWindow_close(screen);
        }

        // Update Stuff
        Cursor_Position.x = sfMouse_getPosition(screen).x;
        Cursor_Position.y = sfMouse_getPosition(screen).y;
        sfSprite_setPosition(Cursor_Sprite, Cursor_Position);

        // Draw Stuff
        sfRenderWindow_drawSprite(screen, Cursor_Sprite, NULL);

        // Display it
        sfRenderWindow_display(screen);

        // Clear Window
        sfRenderWindow_clear(screen, sfBlack);
    }

    // Clean up
    sfSprite_destroy(Cursor_Sprite);
    Cursor_Sprite = NULL;
    sfTexture_destroy(Cursor_Texture);
    Cursor_Texture = NULL;
    sfRenderWindow_destroy(screen);
    screen = NULL;

    return 0;
}

Hope that will solve your problem

passing argument 1 of 'sfMouse_getPosition' from incompatible pointer type [-Wincompatible-pointer-types]

Please make an update for csfml, and make magic stuff with CPP.

I saw a topic about this at the year: on: 2012
https://en.sfml-dev.org/forums/index.php?topic=7761.msg51675#msg51675

Thats atleast 5 Years...

Is there no support anymore for the C Binding ? That makes me sad...

Yes, there is support for the C binding, through highly welcomed community contributions for example. If you see something that can be improved, we have a set of Contribution Guidelines which should also apply for CSFML.  ;)

Hey Hiura,

thanks for replay. As you saw in my last post, i wrote "magic stuff with CPP", in this answer you can see, i dont have any bit of knowledge of C++.

In my highly noobyness i would say, just append another Function with an other function argument in the Mouse.cpp ( https://github.com/SFML/CSFML/blob/master/src/SFML/Window/Mouse.cpp )
and rename the other function.
Use a generic define in Mouse.h File and go?

Code: [Select]
////////////////////////////////////////////////////////////
// Renamed
sfVector2i sfMouse_getPosition_WN(const sfWindow* relativeTo)
{
    sf::Vector2i sfmlPos;
    if (relativeTo)
        sfmlPos = sf::Mouse::getPosition(relativeTo->This);
    else
        sfmlPos = sf::Mouse::getPosition();

    sfVector2i position = {sfmlPos.x, sfmlPos.y};
    return position;
}

////////////////////////////////////////////////////////////
// with RenderWindow
sfVector2i sfMouse_getPosition_RW(const sfRenderWindow* relativeTo)
{
    sf::Vector2i sfmlPos;
    if (relativeTo)
        sfmlPos = sf::Mouse::getPosition(relativeTo->This);
    else
        sfmlPos = sf::Mouse::getPosition();

    sfVector2i position = {sfmlPos.x, sfmlPos.y};
    return position;
}

In the Mouse.h
Code: [Select]
...
CSFML_WINDOW_API sfVector2i sfMouse_getPosition_WN(const sfWindow* relativeTo); // The Normal Function
CSFML_WINDOW_API sfVector2i sfMouse_getPosition_RW(const sfRenderWindow* relativeTo); // The RenderWindow Function
...
#define sfMouse_getPosition(X) _Generic((X), sfWindow*: sfMouse_getPosition_WN, sfRenderWindow*: sfMouse_getPosition_RW)(X)
...

I just make a minimal example with the generic stuff
Code: [Select]
float Test1(const float* A)
{
    return A[0] + 2.0f;
}

int Test2(const int* B)
{
    return B[0] + 4;
}

#define Test(X) _Generic((X), float*: Test1, int*: Test2)(X)


int main (void)
{
    float Float_Array[2] = {5.0f, 0}; // just for testing a pointer type
    int Int_Array[2] = {10, 0}; // just for testing a pointer type
    printf("Test Float: %f\n", Test(Float_Array)); // Outputs 5.00 + 2.00 = 7.0000
    printf("Test Integer: %d\n", Test(Int_Array)); // Outputs 10 + 4 = 14
    return 0;
}

(compiled -std=c11)

Maybe theres a easier way in magic cpp. Not easy to oversee the billion of semantics in CPP.

CSFML can't use C11 features, at least for now. But there's no need for "magic" there, you know the type of your window so just call the correct function -- which does exist, by the way: see the extra sfMouse_* functions in RenderWindow.h.

Hey Laurent,

thanks for feedback. That hint must be a secret ! :o
I should read some of the auto-suggestions exactlier if i type some functions in my editor ;-)

I know this this post is old but please if you can let us know that did any of these worked or not and if worked then which one?
