Up-to-date Go bindings for SFML, the Simple and Fast Multimedia Library.
These bindings are entirely generated using SWIG and the official C bindings of SFML.
Hence they should be fairly easy to maintain & keep in sync with future releases from upstream.

I have only tested these on darwin/amd64, using the latest macOS Sierra.
Feel free to open issues and/or PRs if you're running into problems on other platforms.
Assuming both libraries and their header files are correctly installed and available through the standard paths of your system:
$ go get -u gopkg.in/teh-cmc/go-sfml.v24/...
That's it!
The generated APIs very closely follow those of SFML's C bindings: the tutorials & documentation available for the official C++ implementation, as well as an editor with a well configured Go-autocompletion, will get you a long way.
The original C & C++ implementations of SFML come with 5 modules: Audio, Graphics, Network, System and Window.
Of these 5 modules:
- Audio, Graphics & Window come with complete Go packages counterparts
- System also has a dedicated Go package, but only contains the
sfVector2&sfVector3classes; everything else is already available in one form or another in Go's standard library - Network has been entirely discard, use Go's standard library instead
Here's a straightforward example of creating a window and handling events:
package main
import (
"runtime"
"gopkg.in/teh-cmc/go-sfml.v24/graphics"
"gopkg.in/teh-cmc/go-sfml.v24/window"
)
func init() { runtime.LockOSThread() }
func main() {
vm := window.NewSfVideoMode()
defer window.DeleteSfVideoMode(vm)
vm.SetWidth(800)
vm.SetHeight(600)
vm.SetBitsPerPixel(32)
/* Create the main window */
cs := window.NewSfContextSettings()
defer window.DeleteSfContextSettings(cs)
w := graphics.SfRenderWindow_create(vm, "SFML window", uint(window.SfResize|window.SfClose), cs)
defer window.SfWindow_destroy(w)
ev := window.NewSfEvent()
defer window.DeleteSfEvent(ev)
/* Start the game loop */
for window.SfWindow_isOpen(w) > 0 {
/* Process events */
for window.SfWindow_pollEvent(w, ev) > 0 {
/* Close window: exit */
if ev.GetXtype() == window.SfEventType(window.SfEvtClosed) {
return
}
}
graphics.SfRenderWindow_clear(w, graphics.GetSfRed())
graphics.SfRenderWindow_display(w)
}
}For comparison's sake, the exact same thing in C:
#include <SFML/Window.h>
#include <SFML/Graphics.h>
int main() {
sfVideoMode mode = {800, 600, 32};
sfRenderWindow* window;
sfEvent event;
/* Create the main window */
window = sfRenderWindow_create(mode, "SFML window", sfResize | sfClose, NULL);
if (!window)
return 1;
/* Start the game loop */
while (sfRenderWindow_isOpen(window)) {
/* Process events */
while (sfRenderWindow_pollEvent(window, &event)) {
/* Close window : exit */
if (event.type == sfEvtClosed)
sfRenderWindow_close(window);
}
/* Clear the screen */
sfRenderWindow_clear(window, sfRed);
sfRenderWindow_display(window);
}
/* Cleanup resources */
sfRenderWindow_destroy(window);
}
