Im trying to run this tutorial: [url]http://www.sfml-dev.org/tutorials/1.6/graphics-window.php[/url]
when i use the code on the tutorial

#include <SFML/Graphics.hpp>

int main()
{
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");

    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();

            // A key has been pressed
            if (Event.Type == sf::Event::KeyPressed)
            {
                // Escape key : exit
                if (Event.Key.Code == sf::Key::Escape)
                    App.Close();

            }
        }

        // Clear the screen with red color
        App.Clear();

        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}

i get:
[quote]Segmentation fault
Process returned 139 (0x8B)[/quote]
yet when i remove the:

App.Clear();

it works (although the window gets full of static).
Using ubuntu, SFML 1.6 and i have an integrated graphics card if it matters

Where does it crash? Run a debugger.

EDIT: To clarify, while removing lines help debugging, it could be any call after that 'Clear' that actually crashes. Debugging without a debugger is futile :)

[Richy13]

just ran the codeblocks debugger and got this

Okay so it's really a chain of events from the clear call, weird.

If you're using 1.6 why does your library say 1.5? Might want to try and build the latest libs, actually you should probably just move to SFML2 and compile those.

[QUOTE=Richy19;25379626]I downloaded the 2.0 snapshot but i couldnt get it to compile in linux

I just tried and it compiled fine, apart from a few warnings out of stb_image.h which can be fixed by donwloading the [url=http://nothings.org/stb_image.c]newest one[/url] (the SFML guy (Laurent?) just renamed it ), using gcc 4.4.3 on 64-bit Linux. Also works fine with clang 1.1.
I build it via GNU Make and the supplied makefile.

[Richy13]

what folder do you go into when you run the make command?
just the main sfml one?
also how do i check what version of GCC i have?

[ZeekyHBomb]

Yeah, just the sfml2 directory, which popped out of the gz.
gcc -v

[Richy13]

do you use "sudo make install"?

[Chandler]

Rather than clearing with the default, have you tried explicitly placing a color inside of it?

[ZeekyHBomb]

[QUOTE=Richy19;25380083]do you use "sudo make install"?[/QUOTE]

Well, I just executed make; install would just take care of copying the libraries to the lib-directory.

[editline]13th October 2010[/editline]

Using sudo make install worked fine too though (did a clear before, just in case).

[Richy13]

how do you do clear?

[QUOTE=Chandler;25380190]Rather than clearing with the default, have you tried explicitly placing a color inside of it?[/QUOTE]

yea i tried using the color that the tutorial gives you as well

woo hoo managed to compile it and install it
but now my projects are still linking with the old version...

I have managed to compile with the new SFML version by manually selecting the libraries.
But does anyone know if theres an easier way to select them like you did with the old files?

Hi guys, i have a little problem, i have a function to generate a list of tiles(as pictureboxes (just in the editor)) it works fine so far but it really only does one tile, and i know there are two.

Here is the code:

public static void GenerateTileList(ref Panel parent)
        {
            Bitmap bmp = new Bitmap(@"content/textures/editor/textures.png");
            int i = 1;
            foreach (KeyValuePair<String, Microsoft.Xna.Framework.Rectangle> texture in textureBank)
            {
                MessageBox.Show(i.ToString() + "Out of:" + (textureBank.Count).ToString());

                Vector2 Pos = Vector2.Zero;
                PictureBox disposable = new PictureBox();
                System.Drawing.Rectangle srcRect = new System.Drawing.Rectangle(texture.Value.X, texture.Value.Y, 32, 32);
                disposable.Image = (Image) bmp;
                parent.Controls.Add(disposable);
                disposable.Size = new System.Drawing.Size(32, 32);

                

                parent.CreateGraphics().DrawImage(disposable.Image, Pos.X, Pos.Y, srcRect, System.Drawing.GraphicsUnit.Pixel);

                pBList.Add(
                    texture.Key,
                    disposable
                    );

                Pos.X += 32; Pos.Y += 32;
                i++;
            }
        }

And here is the output from the messagebox:

[QUOTE=Messagebox.Show()]

But the parent panel only has one tile on it.

[b]*** Update: ***[/b]
I rewrote the function and fixed it:

public static void GenerateTileList(Panel parent)
        {
            Bitmap bmp = new Bitmap(@"content/textures/editor/textures.png");
            System.Drawing.Point pt = new System.Drawing.Point(0, 0);

            foreach (KeyValuePair<String, Microsoft.Xna.Framework.Rectangle> texture in textureBank)
            {
                pBList.Add(
                    texture.Key,
                    new PictureBox()
                    );

                
            }

            foreach (KeyValuePair<String, PictureBox> pb in pBList)
            {
                pb.Value.Image = (Image)bmp;
                pb.Value.Size = new System.Drawing.Size(32, 32);
                pb.Value.Location = pt;
                parent.Controls.Add(pb.Value);
                pb.Value.Show();


                pt.X += 32;
                if(pt.X >= 192)
                    pt.Y += 32;
            }
        }

[nos217]

Argh, segfault at a weird area. For some reason this:

while (cin >> new_word)
		words.push_back(new_word);

causes Segmentation Fault. Anyone have any ideas? I haven't tried a debugger because I'm using gvim and I haven't tried to understand how to use a debugger with it.

[jA_cOp]

Make sure [I]words[/I] is not a dangling reference (if it is a reference, of course).

But you should really get a debugger working. Are you even sure that's where the segfault is caused?

[nos217]

Shouldn't be. Here's the full code:

#include <string>
#include <vector>
#include <iostream>

using std::vector;
using std::string;
using std::endl;
using std::cout;
using std::cin;

bool palindrome(const string& word)
{
	typedef string::size_type str_sz;

	int i;
	str_sz wordsize = word.size();
	str_sz halfword = wordsize/2;

	while (i != halfword + 1) {
		if (word[i] != (word[wordsize - i - 1])) {
			return false;
		}

		++i;
	}

	return true;
}

vector<string> extract_palindromes(vector<string>& words)
{
	vector<string> extracted;
	
	for (vector<string>::const_iterator i = words.begin();
		i != words.end(); ++i) {
		
		if (palindrome(*i))
			extracted.push_back(*i);
	}
	return extracted;
}

int main() {
	vector<string> words;

	cout << "Please enter a list of words followed by end-of-file."
		<< endl << endl;
	
	string new_word;
	while (cin >> new_word)
		words.push_back(new_word);

	vector<string> palindromes;
	palindromes = extract_palindromes(words);

	cout << "There are " << palindromes.size() << " palindromes in that list!" << endl
		<< "They are as follows:" << endl;

	for (vector<string>::const_iterator i = palindromes.begin();
		i != palindromes.end(); ++i)
			cout << *i << endl;
	
	return 0;
}

Yeah I'll do that just now actually.

I can't figure out a way to make craftables in my Textcraft project, anyone have an idea on how i could do it? (my current code doesn't work if my craftables together uses the same items more than once).

Old, buggy code:

[cpp]public void Combine(Item itemA, Item itemB)
{
bool hasItems = false;
bool hasA = false;
bool hasB = false;

Item newItem = new Item("Invalid Item");

if (inventoryList.Contains(itemA) && inventoryList.Contains(itemB))
hasItems = true;

if (hasItems)
{
bool insideParsing = false;

TextReader textReader;
textReader = new StreamReader(FileSystem.defaultDir + "\\Items.txt");

foreach (string line in textReader.ReadToEnd().Split('\n'))
{
string l;
//Console.WriteLine(line);
if (!insideParsing)
{
if (line.ToLower().StartsWith("c{"))
{
insideParsing = true;
Console.WriteLine("Entering crafting parse");
}
}
else
{
if (line.ToLower().StartsWith("itema="))
{
l = line.Remove(0, 6);
l = l.Replace("\r", "");

Console.WriteLine("Item A = " + l);

if (l == itemA.ItemName || l == itemB.ItemName)
{
RemoveItem(itemA);
hasA = true;
}

continue;
}

if (line.ToLower().StartsWith("itemb="))
{
l = line.Remove(0, 6);
l.Replace(" ", "");
l = l.Replace("\r", "");

Console.WriteLine("Item B = " + l);

if (l == itemB.ItemName || l == itemA.ItemName)
{
RemoveItem(itemB);
hasB = true;
}

continue;
}

if (hasA && hasB)
{
if (line.ToLower().StartsWith("newitem="))
{
l = line.Remove(0, 8);
l = l.Replace("\r", "");

foreach (Item item in World.worldItems)
{
if (item.ItemName == l)
{
AddItem(item);
newItem.ItemName = l;
}
}
}

hasA = false;
hasB = false;
hasItems = false;
break;
}
}

l = null;
}

Console.WriteLine("Mixed " + itemA.ItemName.ToLower() + " with " + itemB.ItemName.ToLower() + " and got " + newItem.ItemName.ToLower() + ".");
}
else
{
TextBuffer.Add("You don't have enough of these items on you.");
}
}[/cpp]

C{

ItemB=B

You mean ItemA == ItemB (references are equal)? If so, could it be a problem to remove the same item twice?

I don't really know one on top of my head, but a simple binary format would do, would it not?
Like

header:
  magic bytes
  xsize: 10bits (or if you want it easier to parse, 2bytes)
  ysze: 10bits

This header is followed by xsize*ysize elements, ordered however you like
element:
  numProperites: 1byte (leaves room for [minProperties..255 + minProperties] properties)
  this is followed by numProperties property-types

if i would craft lava and sand together, i'd get obsidian, or "invalid item"(not completely sure tbh). The cause is unknown to me. :confused:

I'm guessing it has to do with the order of how i create them in the text file. Obviously, i need a way to make it independant from that.

There would probably be a problem removing the same item twice, but it's only doing that if, for example ItemA or ItemB = what the player entered when he wrote the crafting command, and i haven't done that.

Oh yeah, now I get it.
Well, you should stop parsing the insideParsing-stuff upon encountering a }. Upon that even you can also check if hasA && hasB (not before) and if that is true, break out of the loop; else continue (in which case it would yet again try to find a "c{").

I hope this is not the road you plan on going though. You should parse the file properly and lay it into a structure in memory somehow.
Funny thing, I am doing the same shit at this moment as well :D
Not file parsing, but a C++ class for items that can also possibly be combined and produce results. Parsing this info from a file is trivial though.
