DotNet / System.DllNotFoundException on Mac OS

« on: August 19, 2019, 06:57:50 am »

I'm on Mac OS Mojave using Visual Studio Community 2019.

First I created a blank C# project. Then I installed the SFML.Net NuGet. After that, this is what my packages.config file looked like:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="CSFML" version="2.5.0" targetFramework="net47" />
  <package id="SFML.Audio" version="2.5.0" targetFramework="net47" />
  <package id="SFML.Graphics" version="2.5.0" targetFramework="net47" />
  <package id="SFML.Net" version="2.5.0" targetFramework="net47" />
  <package id="SFML.System" version="2.5.0" targetFramework="net47" />
  <package id="SFML.Window" version="2.5.0" targetFramework="net47" />
</packages>

I then create a simple main program:

using System;
using SFML;
using SFML.Graphics;
using SFML.Window;

namespace HelloSFML
{
    class MainClass
    {
        private static RenderWindow _window;

        public static void Main(string[] args)
        {
            _window = new RenderWindow(new VideoMode(640, 480), "Hello SFML!");
            _window.SetVisible(true);
            _window.Closed += new EventHandler(OnClosed);
            while (_window.IsOpen)
            {
                _window.DispatchEvents();
                _window.Clear(Color.Black);
                _window.Display();
            }
        }

        private static void OnClosed(object sender, EventArgs e)
        {
            _window.Close();
        }
    }
}

After building, I then copy the following files to my the Debug/bin folder of my project:

libcsfml-audio.2.5.0.dylib
libcsfml-graphics.2.5.0.dylib
libcsfml-network.2.5.0.dylib
libcsfml-system.2.5.0.dylib
libcsfml-window.2.5.0.dylib

I then also create a file called sfmlnet-graphics.dll.config in that same folder with the following contents:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
        <dllmap dll="csfml-graphics" target="libcsfml-graphics.2.5.0.dylib"/>
        <dllmap dll="csfml-audio" target="libcsfml-audio.2.5.0.dylib"/>
        <dllmap dll="csfml-window" target="libcsfml-window.2.5.0.dylib"/>
        <dllmap dll="csfml-system" target="libcsfml-system.2.5.0.dylib"/>
        <dllmap dll="csfml-network" target="libcsfml-network.2.5.0.dylib"/>
</configuration>

However, when I run the program, I get the following exception:

{System.DllNotFoundException: csfml-graphics
  at (wrapper managed-to-native) SFML.Graphics.RenderWindow.sfRenderWindow_createUnicode(SFML.Window.VideoMode,intptr,SFML.Window.Styles,SFML.Window.ContextSettings&)

  at HelloSFML.MainClass.Main (System.String[] args) [0x00001] in /Users/rutvik/Desktop/hello-csharp/hello-csharp/MainClass.cs:14 }

I'm really not sure what other steps are required to get this to work. There are some other posts on this forum:

^ Both of those posts seem inconclusive and don't fix my problem (from what I can tell). Not sure what other steps are needed to get this to work...

Java / Re: Trouble setting the viewport

Hi sorry to bother you, but have there been any developments?

Java / Trouble setting the viewport

« on: September 09, 2013, 02:28:16 am »

I made a very simple app to test JSFML and learn how to use views, but when I tried to set the viewport, nothing happened; the view still takes up the whole screen when it should take up half. I looked through my code a few times, but I was unable to catch the problem. I've tested similar code in the c++ version and it works, so I'm not sure if there's a difference in how I need to use the viewports in java or if I'm making a silly error...

If anyone could point me to the problem I'd really be grateful.

        RenderWindow window = new RenderWindow();
        ContextSettings ctxSettings = new ContextSettings(8);
        int screenWidth = 720;
        int screenHeight = 480;
        window.create(new VideoMode(screenWidth, screenHeight),
                              "JSFML Test",
                               RenderWindow.CLOSE | RenderWindow.TITLEBAR,
                               ctxSettings);

        window.setVerticalSyncEnabled(true);
       
        Texture bgTexture = new Texture();
       
        // load the bg picture with an InputStream
       
        Vector2i worldSize = bgTexture.getSize();
       
        RectangleShape bg = new RectangleShape();
        bg.setPosition(0,0);
        bg.setSize(new Vector2f(bgTexture.getSize()));
        bg.setTexture(bgTexture);
       
        View view = new View(window.getDefaultView().getCenter(), new Vector2f(screenWidth, screenHeight));
        view.setViewport(new FloatRect(0, 0, 0.5f, 1.f));
        window.setView(view);
       
        RectangleShape player1 = new RectangleShape();
        player1.setSize(new Vector2f(20, 20));
        player1.setPosition(0, 0);
        player1.setFillColor(Color.RED);
        int player1MoveSpeed = 200;
       
        Clock clock = new Clock();
        while (window.isOpen())
        {
            window.clear();
                   
            window.draw(bg);
            window.draw(player1);
                   
            window.display();

            float dt = clock.restart().asSeconds();        
           
            // move the player at `player1MoveSpeed`
           
            for (Event event : window.pollEvents())
            {
                switch (event.type)
                {
                    case CLOSED:
                        window.close();
                        break;
                }
            }

General / SFML Empty Application Xcode template

« on: July 13, 2012, 02:54:25 am »

I downloaded SFML 2.0 using the wizard, and got everything up an running smoothly. However, the templates given aren't empty, they have some sample files and sample code. I know I could just delete the files and the sample code, but it gets annoying to do that every time I want to create an SFML project. Does anyone know how to edit the xctemplate files that control the given templates, or has anyone already made a blank project template themselves?

Graphics / Re: Animating a sprite independently from the main loop

« on: July 09, 2012, 09:04:59 pm »

That would work too! Thanks!

And one more thing, how do I restart the flash? If I simply reset m_accumulatedTime back to 0, it'll just keep flashing. Should I use a static bool in this case (for example called isFlashing)?

m_accumulatedTime is most likely static correct?

Graphics / Animating a sprite independently from the main loop

« on: July 09, 2012, 08:23:53 pm »

So i have a sprite that needs to flash when it gets hit, and for convenience purposes, let's say (theoretically) I have a flash method in the spaceship object class like so

class Spaceship: public Object {
public:
   void flash()
   {
      if (t < 1.5) {
         float opacityRatio = cos(3t);
         sprite.setColor(sf::Color(255,255,255,255*opacityRatio));
      }
   }
};
 

The problem is that how do I get the "t" value? The game loop is repeated multiple times and relies on a clock, so if I use the clock value (which gets reset ever iteration) for "t" , the whole flash animation will mess up. So how do I get the "t" value? Should I use static variables (however I have a feeling that implementation isn't very graceful), or should I animate it in a separate thread (although I'm not sure it's possible)? Games use effects like this all the time, so I'm sure there's an easy way... Any suggestions/solutions would be extremely helpful.

Graphics / Best way to display sprites

« on: June 18, 2012, 03:38:52 am »

I have a window on which I'm going to display a ton of sprites for a game. I'm using SFML 2.0 which adds a view to windows automatically, which is good I hear because it converts measurements and locations for the window so it behaves the same, regardless of size. Problem is, when I resize the window, it stretches/shrinks all the sprites. Is there a way to resize the window but NOT the view? And what is the best way to set up views/windows to adjust to ALL resolutions? Because I want the game to look more or less the same on ALL screen sizes... thanks.

Window / Get the x/y coordinates of a window

« on: June 08, 2012, 08:11:30 pm »

I have a window that I'm using for a game, and I'm going to use the windows function ClipCursor()to confine the mouse to the window like make game do. However, I need to know how to get the coordinates of the window. I've looked through the documentation, but I can't seem to find it. Is there any way to do this? I plan on moving to mac later on, so cross-platform solutions would be best.

Graphics / Re: Rotating a sprite

« on: June 01, 2012, 06:43:35 am »

I've tried that before, but it doesn't work. Specifically I tried it like this before:

void CSprite::setRotation(float degrees)
{
   drawable.SetCenter(get_width()/2, get_height()/2);
   drawable.SetRotation(degrees);
   drawable.SetCenter(0, 0);
}

Graphics / Rotating a sprite

« on: June 01, 2012, 02:19:57 am »

I have this sprite I want to rotate, but when I call SetRotation() on it, it behaves weird, like the hinge is on the top left corner. I'm aware that I can use SetCenter() to place the hinge in the center of the sprite, but I like positioning elements using the top left corner. I wrote a wrapper class for sf::Sprite and wrote the setRotation() method like this:

void CSprite::setRotation(float degrees)
{
   float oldXCenter = drawable.GetCenter().x;
   float oldYCenter = drawable.GetCenter().y;
   drawable.SetRotation(degrees);
   drawable.SetPosition(oldXCenter, oldYCenter);
}

But it still doesn't do what I want... Does anyone have a solution?

That's the default I think, and it still appears blurry.

Graphics / Large text appears blurry

« on: May 22, 2012, 07:21:19 pm »

I use the sf::String class to show text on the screen, and it looks okay at small sizes, but if I make the text 96pt, the it appears really blurry. I did SetSmooth(false) on the sf::Font object, but the it appears blurry and pixel-y! Is there any way  to have large, clean-looking text in SFML 1.6?

Graphics / Re: Help with rotating a sprite

« on: May 11, 2012, 08:32:18 pm »

Can it be done with SFML 2? And if so, how?

And the way I'm currently getting around the situation is by just center-positioning all the sprites internally, and using the wrapper class to make it behave like I'm positioning using the top left corner. Would you say this is bad design?

Graphics / Help with rotating a sprite

« on: May 10, 2012, 11:20:47 pm »

I have a character sprite that I need to rotate to face up, left, right, and down. The way I'm currently rotating it is like this:

(SpriteX is a wrapper class I made around an sf::Sprite, and these are some rotation methods)

void SpriteX::rotate(float degrees)
{
   sprite.SetCenter(get_width()/2, get_height()/2);
   sprite.Rotate(degrees);
   sprite.SetCenter(0, 0);
}

void SpriteX::set_rotation(float degrees)
{
   sprite.SetCenter(get_width()/2, get_height()/2);
   sprite.SetRotation(degrees);
   sprite.SetCenter(0, 0);
}
 

The sprite still rotates around its top left corner, how do I make it rotate around it's center just for the scope of the rotation method? I still want to position the sprite based on its top left corner.

Will I just have to make 4 separate image files?

Any help is appreciated!
