C / CSFML for Ubuntu Lunar Lobster

« on: October 02, 2023, 05:02:34 am »

Hi SFML community,

I have recently been forced to upgrade my Ubuntu version to Ubuntu 23.04 Lunar Lobster (x86-64).

I'm having a hell of a time trying to install CSFML on my system (SFML binaries from www.sfml-dev.org work fine). The packages I downloaded using Synaptic Package Manager / Apt were empty and I cant figure out how to install from source.

Is there any way that I can get hold of the CSFML headers and binaries that were available in apt with a previous version of Ubuntu? Does anyone have the headers and binaries they can send me?

Kind regards,
Boston

I downloaded the software objects from https://packages.ubuntu.com/search?suite=kinetic&searchon=names&keywords=csfml and got the headers from the csfml source code, and all is well.

Graphics / Sprite gets mirrored?

« on: July 08, 2018, 08:25:12 am »

How come when I use sfTexture_copy everything goes as expected,
But if I create a Sprite based on the source texture and draw it to a RenderTexture that contains the destination texture, the result is a mirror image of what I was hoping for.
I can work around this by setting the y-scale of the sprite to -1 but I'd like to know why this behavior occurs in the first place.

C / sfCircleShape_setOrigin();

« on: March 21, 2016, 07:59:49 am »

Ive been experimenting, trying to get sfRenderWindow_drawCircleShape() to work,
it does work, but the function sfCircleShape_setOrigin() accepts coordinates that are scaled and negated.

eg.
#include <time.h>
#include <SFML/System.h>
#include <SFML/Graphics.h>
#include <SFML/Window.h>
#include <stdio.h>
#include <math.h>
#include <stdlib.h>

int main(void) {
#define SCREEN_HEIGHT 300
#define SCREEN_WIDTH 400

sfVideoMode mode = {SCREEN_WIDTH, SCREEN_HEIGHT, 32};
sfRenderWindow *window = sfRenderWindow_create(mode, "SFML window", sfResize | sfClose, NULL);

sfCircleShape *SelectedCircle = sfCircleShape_create();
sfVector2f scale;
scale.x = 1;
scale.y = 0.5;
sfCircleShape_setScale(SelectedCircle, scale);
sfVector2f origin;
origin.x = -150;
origin.y = -150;
sfCircleShape_setOrigin(SelectedCircle, origin);
sfCircleShape_setRadius(SelectedCircle, 100);

sfCircleShape_setFillColor(SelectedCircle, sfTransparent);
sfCircleShape_setOutlineColor(SelectedCircle, sfCyan);
sfCircleShape_setOutlineThickness(SelectedCircle, 5.0);

sfRenderWindow_clear (window, sfColor_fromRGB (255,255,255));
sfRenderWindow_drawCircleShape(window, SelectedCircle, NULL);
//sfCircleShape_destroy(SelectedCircle);

sfRenderWindow_display(window);
while (1) {}
}

produces something like the attached image.

Thats OK, what you described is what I have been doing.
I have been doing many small experiments of what I need for my engine,
although I wouldnt expect to produce a commercial-grade product in like five years.
Working things out for myself is something i excell at,
but I was hoping some pro would swoop in and give me an easy answer.

Its annoying having to convert between textures and rendertextures.
I may decide to switch to a different media library.

Wotevs OK have nice day.
