General / I'm becoming insane

« on: November 19, 2011, 11:45:17 pm »

I recompiled SFML 1.6 because of a random problem with sprites... and everything went peachy, with no errors or warnings. When I tried to run my program(which loads a sprite, displays it etc etc) I get this

Code: [Select]

I searched the forum, the answers were to include sfml-window debug library, searched the internet, checked the path... I'm stumped.

Graphics / Failed to load image "". Reason : Unable to open f

« on: November 09, 2011, 10:50:40 pm »

sorry, this is the most minimal I can to reproduce the bug

I don't think so
The most minimal that you can do is a main that loads and play the sound. Then if it works (which is what I expect), focus on the 1% of your code that is different between both versions. That should produce another minimal code, that you can debug much more easily than your whole project. Etc, etc....

People just give up when they face a bug that they can't explain immediately, like if there was nothing to do. But it's your code, you wrote it, and you wrote the bug too, so there's always something you can do to find it and fix it -- with some extra work. Don't be afraid to write or remove code just for debugging.

And if you happen to find a really minimal code that still has the problem, then I'll be able to tell you whether it's a bug in SFML or not.

http://www.sfml-dev.org/forum/viewtopic.php?p=36368#36368

I am sorry again for wasting your time. On the other hand, I think the problem is with Visual Studio 2010 project configurations... I'll just reset them and/or rebuild SFML

Graphics / Failed to load image "". Reason : Unable to open f

« on: November 06, 2011, 10:53:05 pm »

Can you provide a complete and minimal example that reproduces the problem?

I'll post the whole code, without obfuscation:

He wanted less code, not more, keyword "minimal". Most of the time people don't have time to read through other people's code in details so you need to keep it brief if you have a chance of getting help.

My bad, didn't read thoroughly

Regarding the code, it works in my second "non-obfuscated" post, but it fails to do so in the first one, even though the code is 99% the same... sorry, this is the most minimal I can to reproduce the bug

Graphics / Failed to load image "". Reason : Unable to open f

The error message suggests that somehow your image filename is empty.

The only difference between this program and the program that worked, is that this program uses images created by myself, and the other one used images from the internet.

Graphics / Failed to load image "". Reason : Unable to open f

... is the error message I get after I run my program. I've checked the paths, they are ok, copied the images from their folder into the root of the program, even changed them from JPG to PNG and nothing... same error message for each image that is being loaded. It worked before in an other program, which was not much different from this one in terms of classes and such.
Here is the code:

main.cpp:

Code: [Select]


#include <iostream>
#include "kareninacharacter.h"
#include "blocks.h"
#include "mappings.h"

#define NAME "To heaven with you"


using namespace std;

int main() {

sf::RenderWindow *pApplication = new sf::RenderWindow(sf::VideoMode::GetMode(0), NAME, sf::Style::Fullscreen);

Blocks *pBackground = new Blocks(PLACEHOLDER);

kareninaCharacter *pPlayableCharacter = new kareninaCharacter(PLAYABLE_CHARACTER);

sf::Shape Floor = sf::Shape::Rectangle(0, 4800, 5000, 5000, sf::Color(50, 50, 50, 0)); //replace with Blocks

bool running = pApplication->IsOpened();

while(running)
{
sf::Event Event;

while(pApplication->GetEvent(Event))
{
if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
{
pApplication->Close();
}
}

pApplication->Clear();


pApplication->Draw(pBackground->getSprite());

pApplication->Draw(Floor);

pApplication->Draw(pPlayableCharacter->getSprite());

pApplication->Display();
}

return 0;
}



mappings.h:

Code: [Select]


#ifndef MAPPINGS_H_
#define MAPPINGS_H_

#define PLACEHOLDER "placeholder.png"
#define PLAYABLE_CHARACTER "pc.png"

#endif


Also, the Blocks and kareninaCharacter class are pretty much the same, except the latter one has a few more methods, but the process of loading images and sprites is the same and as in the tutorial:

Code: [Select]


Blocks(string imglocation)
{

this->imgLocation = imgLocation;
Image.LoadFromFile(imgLocation);

Sprite.SetImage(Image);

}


I am using Visual Studio 2010 on Win7 x64

Code: [Select]


            if(indicator)
            {
               Sprite.SetImage(pMegusta->Image);
               indicator = false;
            }
            else
            {

            }
 

Sorry, but... =)

Code: [Select]


Sprite.SetImage(indicator ? pMegusta->Image : pMudkip->Image);
indicator = !indicator;


Ah, ye olde ternary operator powerful, yet used by few

OK I found your bug, the fact you're using VS2010 doesn't have anything to do with it

you just put

Code: [Select]

     bool indicator = true; inside your main loop meaning that it was resetting to true each frame. You needed to put it before

Code: [Select]

while(running)

Tried it just now, it seems that whenever I press any key that is in the event loop it starts switching sprites like crazy without displaying the first sprite... I tried adding it to the end of the event loop, but no avail, it is the same except it displays the first sprite.

EDIT: I feel like an idiot... i didn't put the key detection routine... it works now flawlessly thank you all

I haven't read through all of it because there is a lot of utilities:: that was making me dizzy, but I think this is your problem

Code: [Select]


            if(indicator = true)
            {
               Sprite.SetImage(pMegusta->Image);
               indicator = false;
            }
            else if(indicator = false)
            {
               Sprite.SetImage(pMudkip->Image);
               indicator = true;
            }

1. You need == not =
2. You need not compare to true or false at all!, and the second if condition is unnecessary. Change it to this

Code: [Select]


            if(indicator)
            {
               Sprite.SetImage(pMegusta->Image);
               indicator = false;
            }
            else
            {
               Sprite.SetImage(pMudkip->Image);
               indicator = true;
            }

Tried with both =='s and with your example, nothing. It just changes the sprite to the Me Gusta face on the first key press, and on the second it does nothing.

Sorry for the utilities part, as I said, my aim is to make this program bloated

I'm using VS2010, if it matters...

No problem

This is my event loop. Currently, it is supposed to change a sprite first from a Slowpoke to a Me Gusta face, and then change it to a Mudkip. And it fails to work:

Code: [Select]



#include <SFML/Graphics.hpp>
#include <iostream>

#include "utilities.h"
#include "masterSprite.h"


int main()
{

sf::RenderWindow App(sf::VideoMode::GetMode(0), "I AM SLOWPOKE KING OF SLOW", sf::Style::Fullscreen);
App.UseVerticalSync(true);

bool running = App.IsOpened();


int width = App.GetWidth();
int height = App.GetHeight();

int indicator = 0;

masterSprite *pSlowpoke = new masterSprite("slowpoke.png");
masterSprite *pMegusta = new masterSprite("megusta.png");
masterSprite *pMudkip = new masterSprite("mudkip.png");
masterSprite *pWobbufet = new masterSprite("wobbufet.png");

sf::Sprite Sprite;

Sprite.SetImage(pSlowpoke->Image);

const sf::Input &Input = App.GetInput();

std::cout << width << std::endl;
std::cout << height << std::endl;


while (running)
{
bool indicator = true;

sf::Event Event;


while(App.GetEvent(Event))
{

if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::M))
{
if(indicator = true)
{
Sprite.SetImage(pMegusta->Image);
indicator = false;
}
else if(indicator = false)
{
Sprite.SetImage(pMudkip->Image);
indicator = true;
}
}
if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::R))
{
utilities::r++;
Sprite.Rotate(utilities::r);
}

if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::T))
{
utilities::t++;
Sprite.SetRotation(utilities::t);
}


if(Event.Type == sf::Event::Closed)
{
running = false;
App.Close();
}

if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
{
running = false;
App.Close();
}


if(Input.IsKeyDown(sf::Key::Right))
{
utilities::x += utilities::speed;
if(utilities::x > width)
{
utilities::x = 0;
Sprite.SetPosition(utilities::x,utilities::y);
}
else
Sprite.SetPosition(utilities::x,utilities::y);
}

if(Input.IsKeyDown(sf::Key::Left))
{
utilities::x -= utilities::speed;
if(utilities::x < 0)
{
utilities::x = (float)width;
Sprite.SetPosition(utilities::x,utilities::y);
}
else
Sprite.SetPosition(utilities::x,utilities::y);
}

if(Input.IsKeyDown(sf::Key::Up))
{
utilities::y -= utilities::speed;
if(utilities::y < 0)
{
utilities::y = (float)height;
Sprite.SetPosition(utilities::x,utilities::y);
}
else
Sprite.SetPosition(utilities::x,utilities::y);
}

if(Input.IsKeyDown(sf::Key::Down))
{
utilities::y += utilities::speed;
if(utilities::y > height)
{
utilities::y = 0;
Sprite.SetPosition(utilities::x,utilities::y);
}
Sprite.SetPosition(utilities::x,utilities::y);
}
}

App.Clear();

App.Draw(Sprite);

App.Display();

}
return 0;

}



masterSprite.h:

Code: [Select]


#ifndef MASTERSPRITE_H_

#include <iostream>
#include <SFML\Graphics.hpp>


class masterSprite
{

public:

masterSprite(std::string imgLocation);
~masterSprite() {};

//variables
sf::Image Image;
std::string imgLocation;
};

masterSprite::masterSprite(std::string imgLocation)
{
this->imgLocation;

Image.LoadFromFile(imgLocation);

}

#endif MASTERSPRITE_H_


utilities.h:

Code: [Select]


namespace utilities
{

int speed = 10; //movement speed

float r = 0; //angle for incremental rotation
float t = 0; //angle for regular rotation

float x = 0; //x axis for movement
float y = 0; //y axis for movement

}


Sorry if it's a little bit bloated, I'm making it like that on purpose

I am trying to change sprites when the user presses a key. For instance, there is a sprite of a chicken, if the user presses M, the chicken changes into a plane, and if he/she presses it again, it changes into a snake. I tried putting if's in the event chain after the if that is supposed to pick up the key.. but no luck. Any help? I am sure the answer is simple, but I'm probably too stressed out to see it
