What do you need help with? Version 5

[QUOTE=darkrei9n;35790821]Changed it to a 1D. However still crash.

Where does it crash? calloc should return NULL if it couldn't allocate enough memory.

[QUOTE=nick10510;35790816]Neither is working.

What I use to calculate the cameras position ( it centers the screen on the player ):
[lua]game.CamX, game.CamY = (love.graphics.getWidth()/((game.scale+1)*2)) - ply.Pos.x, (love.graphics.getHeight()/((game.scale+1)*2)) - ply.Pos.y;[/lua][/QUOTE]

Add some print statements about where your camera currently is, where your mouse currently is, and where you click is.

[darkrei9n]

Its not Calloc causing it.

[img_thumb]http://puu.sh/svas[/img_thumb]

Doesn't specify anywhere on the code that I'm writing. I do know its caused by a CreateBuffer() with the exception std::out_of_range.

That should be:

meshVertex* vertexLoad = (meshVertex*) calloc(40*40*40, sizeof(meshVertex));

int i = 0;
for(int x = 0; x < 40; x++)
{
	for(int y = 0; y < 40; y++)
	{
		for(int z = 0; z < 40; z++)
		{
			vertexLoad[i].position = D3DXVECTOR3(x, y, z);
			i++;
		}
	}
}

Only the inner loop should increment the array index; otherwise you're skipping over elements, and will end up running off the end of the array.

Note that I changed "x < 4" to "x < 40" — I'm assuming that was a typo. I also combined the declaration and assignment of vertexLoad into one line, since doing those things separately accomplishes nothing but makes you type the variable name twice.

Also, you should really use named constants like SIZE_X, SIZE_Y, SIZE_Z instead of hard-coding the number 40 all over the place.

[QUOTE=Wyzard;35790955]That should be:

meshVertex* vertexLoad = (meshVertex*) calloc(40*40*40, sizeof(meshVertex));

int i = 0;
for(int x = 0; x < 40; x++)
{
    for(int y = 0; y < 40; y++)
    {
        for(int z = 0; z < 40; z++)
        {
            vertexLoad[i].position = D3DXVECTOR3(x, y, z);
            i++;
        }
    }
}

Only the inner loop should increment the array index; otherwise you're skipping over elements, and will end up running off the end of the array.

Note that I changed "x < 4" to "x < 40" — I'm assuming that was a typo. I also combined the declaration and assignment of vertexLoad into one line, since doing those things separately accomplishes nothing but makes you type the variable name twice.

Also, you should really use named constants like SIZE_X, SIZE_Y, SIZE_Z instead of hard-coding the number 40 all over the place.[/QUOTE]

Still crashing, same error but different spot it appears.

Also not using named constants for now because its simply a test, planning on expanding it later but for now I just want to be able to do a quick test of some stuff.

Hm, since I'm using calloc is it possible that the function doesn't know the upper bound for it?

For Gwen, what .libs do you need for integration with OpenGL?

[QUOTE=Meatpuppet;35790167]It was a typo, and I'm using 64 bit Windows 7.[/QUOTE]

Yes, but are you compiling a 64-bit application? If not, you'll want to use the 32-bit library.

[Wyzard]

[QUOTE=darkrei9n;35791267]Hm, since I'm using calloc is it possible that the function doesn't know the upper bound for it?[/QUOTE]
You mean the size of the buffer that you allocated? It can't determine that from the pointer; you have to specify it separately. I have zero experience with D3D, but looking at the [url=http://msdn.microsoft.com/en-us/library/windows/desktop/bb204896%28v=vs.85%29.aspx]API reference[/url], it looks like the buffer size is the first member of your bufferRet structure. That should be set to 40*40*40*sizeof(meshVertex).

            dsState.DepthBufferFunction = CompareFunction.LessEqual;
            dsState.DepthBufferEnable = true;
            device.DepthStencilState = dsState;

And just in case, this is how i make the vertices to render:

public class Wall : MapPart    {
        public Wall(Vector3 position, float currentwall, float imagesInTexture)
            : base(position)
        {
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, 0, -position.Z - 1), new Vector3(0, 0, 1), new Vector2((currentwall * 2) / imagesInTexture, 1)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, position.Y, -position.Z - 1), new Vector3(0, 0, 1), new Vector2((currentwall * 2 - 1) / imagesInTexture, 0)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, 0, -position.Z - 1), new Vector3(0, 0, -1), new Vector2((currentwall * 2 - 1) / imagesInTexture, 1)));


            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, position.Y, -position.Z - 1), new Vector3(0, 0, 1), new Vector2((currentwall * 2 - 1) / imagesInTexture, 0)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, 0, -position.Z - 1), new Vector3(0, 0, 1), new Vector2((currentwall * 2) / imagesInTexture, 1)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, position.Y, -position.Z - 1), new Vector3(0, 0, 1), new Vector2((currentwall * 2) / imagesInTexture, 0)));


            //back wall
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, 0, -position.Z), new Vector3(0, 0, -1), new Vector2((currentwall * 2) / imagesInTexture, 1)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, 0, -position.Z), new Vector3(0, 0, -1), new Vector2((currentwall * 2 - 1) / imagesInTexture, 1)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, position.Y, -position.Z), new Vector3(0, 0, -1), new Vector2((currentwall * 2 - 1) / imagesInTexture, 0)));

            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, position.Y, -position.Z), new Vector3(0, 0, -1), new Vector2((currentwall * 2) / imagesInTexture, 0)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, 0, -position.Z), new Vector3(0, 0, -1), new Vector2((currentwall * 2) / imagesInTexture, 1)));

That code is messed up because too long lines, but you'll understand it i guess.

[Party Boy]

Trying to make a client chat app.
Just have a quick question wondering if anybody could help me out.

I want a counter for how many clients are in the chat, and I also want to change the serverThread to be a consumer thread.
Anybody have any advice on how to do this?

[url]http://pastebin.com/sXQDtZyz[/url]

[Mordi]

I'm trying to understand this piece of code. Can someone help me out? I don't understand what's going on where the array is being set (line 13). I got it from a tutorial which didn't seem to mention the specifics of this.

[cpp]// Get bitmap properties
int width, height;
width = getNextPower2(bitmap.width);
height = getNextPower2(bitmap.rows);

GLubyte* expanded_data = new GLubyte[2 * width * height];

// Fill in data for expanded bitmap
for(int j=0; j <height;j++)
{
for(int n=0; n < width; n++)
{
expanded_data[2*(n+j*width)]= expanded_data[2*(n+j*width)+1] = (n >= bitmap.width || j >= bitmap.rows) ? 0 : bitmap.buffer[n + bitmap.width*j];
}
}[/cpp]

Edit:
Does it set the value of [b]index n+bitmap.width*j[/b] to [i]0[/i] if the condition [b](n >= bitmap.width or j >= bitmap.rows)[/b] returns [i]true[/i]?

Edit: Nevermind, I figured it out.

I need some advice/ideas on how to generate graph capable of representing city streets (manhattan style, so grid based streets) procedurally.

But I want to be able to do it in chunks (think minecraft chunks) in order to do it in parallel and only when neew areas are needed.

Any ideas?

[DarKSunrise]

Is it a terrible idea to have a window class that can only be created on the heap (as in can only be created with the operator new)? The reason why I'm doing this in the first place is because I want to delete the windows as soon as the user has closed them.

Is there any C ANSI or UNIX function that allows me to do Recursive directory searches? If not, what do I use to search dirs and check dir/file extensions?

[ROBO_DONUT]

It's a pain in the ass.
You need to make yourself a function to list directory contents with readdir() and stat(), then manually repeat for all subdirectories.
readdir() itself isn't re-entrant, so you need to be careful with it. readdir_r is the re-entrant alternative.

BSD has some nice functions for handling directories, which are supported on most Linux systems, but I don't think Windows has them. But even the regular posix stuff is better than WinAPI.

[Gmod4ever]

I don't mean to be a nag or annoying, but I really would like some help with this, and I haven't had any luck since posting this...

[QUOTE=Gmod4ever;35788780]Okay, this makes me feel really incompetent, but I'm going to ask here because Googling has given me only limited success.

So I decided to jump into C++, just because it's something I've been meaning to do. Like all the other times I jump into a new language, I have a goal in mind to work towards, which is, in this case, a fairly straightforward 2D game.

However, I am having some issues.

Basically, I decided I want to try using OpenGL for this. I looked around, and it looks like I want to use SFML. I've seen a lot of people say that "GLEW is almost essential," but it appears that GLEW's sourceforge site is down, so I'm sticking with SFML for now.

However, I have absolutely no idea how to get Visual Studio C++ 2010 to use it, and the few tutorials I've seen for it are either in too poor detail for me to follow, or are otherwise incomplete (one I found referenced some files it "told us to download earlier," but there was no "earlier" and there never was a download, so yeah...)

Anyone got any advice for me? I really don't want to give up on C++ / OpenGL before I can even start, because C++ looks like a fairly fun language to play with, and OpenGL a fairly easy library to work with (at least for simple things, like a 2D game).

Thanks guys. :v:[/QUOTE]

For clarification purposes, I decided to not bother with the linking, but follow the instructions on SFML's website for getting started, pasted below:

[quote]Copy the SFML development files to your Visual Studio installation directory

Copy SFML-x.y\include\SFML to the VC\include directory of your Visual Studio installation (so that you obtain VC\include\SFML)
Copy the *.lib files in SFML-x.y\lib to the VC\lib directory of your Visual Studio installation
[/quote]

And I get the same issues, which is, when I press F5 to compile (I'm doing the sample clock thing on the site [url=http://sfml-dev.org/tutorials/1.6/start-vc.php]here[/url]), I get errors about bad links or something. The errors are here:

1>------ Build started: Project: asdf, Configuration: Debug Win32 ------

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

With this code:

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

int main()
{
    sf::Clock Clock;
    while (Clock.GetElapsedTime() < 5.f)
    {
        std::cout << Clock.GetElapsedTime() << std::endl;
        sf::Sleep(0.5f);
    }

    return 0;
}

I've been looking around, and I guess it's something to do with the version of SFML I'm using being incompatible with VC++ 2010 or something? Any ideas about that?

[QUOTE=Philly c;35797112]I couldn't log in yesterday so little bit late reply, but you're still supposed to use all 3 events.[/QUOTE]

Yeah, it was more just figuring out how exactly to get it. Had a little trickery implementing WM_KEYDOWN/KEYUP again because it required an odd 3-step injection into Awesomium. I'm pretty well set now, been meaning to make sure it's all set and then post the final code here so anyone who finds it on google won't be so alone.
