What do you need help with? Version 5

[darkrei9n]

This is actually driving me insane. Getting error 1407. The weird thing is that this code was copied from another program that works PERFECTLY fine that I also wrote.

bool initWindow(HWND &hWnd, HINSTANCE hInstance, int width, int height)
{
	//Setup Window then register
	WNDCLASSEX wcex;
	
	wcex.cbSize			= sizeof(WNDCLASSEX); 
	wcex.style			= CS_HREDRAW | CS_VREDRAW;
	wcex.lpfnWndProc	= wndProc;
	wcex.cbClsExtra		= 0;
	wcex.cbWndExtra		= 0;
	wcex.hInstance		= hInstance;
	wcex.hCursor		= LoadCursor(NULL, IDC_ARROW);
	wcex.hbrBackground	= (HBRUSH)COLOR_WINDOW;
	wcex.lpszMenuName	= NULL;
	wcex.lpszClassName	= TEXT("Galaxy");
	wcex.hIconSm		= 0;
	RegisterClassEx(&wcex);

	//Setup a RECT to resize window unto
	RECT rect = { 0, 0, width, height };
	AdjustWindowRect(&rect, WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX, FALSE);
	//Create Window finally
	hWnd = CreateWindow(L"Galaxy",
						L"Galaxy DX10",
						WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX,
						CW_USEDEFAULT,
						CW_USEDEFAULT,
						rect.right - rect.left,
						rect.bottom - rect.top,
						NULL,
						NULL,
						hInstance,
						NULL);

	//If !hWnd
	if(!hWnd) 
	{
		DWORD err = GetLastError();
		WCHAR msg[200] = {0};
		wsprintfW(msg, L"Failed with last error: %d", err);
		MessageBoxW(NULL, msg, L"CreateWindow", MB_OK);
		return false;
	}
	//If successful
	ShowCursor(true);
	ShowWindow(hWnd, SW_SHOW);
	UpdateWindow(hWnd);
	return true;
}

What I do know is that the issue is somewhere around wcex.

Line number and specific error please.

[darkrei9n]

[QUOTE=Lord Ned;35564297]Line number and specific error please.[/QUOTE]

It compiles fine, error 1407 is specifically an error with wndclassex and the function registerclassex where the argument (it accepts wndclassex as an argument) does not have certain members filled out right or something.

[dajoh]

You didn't fill in hIcon.

[QUOTE=animorten;35559792]You need to set GL_TEXTURE_(MIN/MAG)_FILTER to GL_NEAREST or GL_LINEAR if you don't have mipmaps[/QUOTE]
Yes, I do not have mipmaps.

I tried these:
[cpp]glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);[/cpp]

[cpp]glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);[/cpp]

But it didn't work. I don't know what I'm doing wrong here. Could it be my shader setup? I'm just using stock shaders.

[url]http://pastebin.com/W4J7EXPu[/url]

Edit: Wait, I got it to render. Turns out I was coloring it with full white. It looks pretty janky, though. Upside-down.

Edit2: Okay, now it seems to render correctly, except for the fact that it's upside down.

Edit3: For some reason, this makes the texture rendering correctly, without being upside down:
[cpp]// Handle the textured quad
glBegin(GL_QUADS);
glColor3f(1, 1, 1);
glTexCoord2d(0.0,1.0); glVertex2d(-0.5,-0.5);
glTexCoord2d(1.0,1.0); glVertex2d(0.5,-0.5);
glTexCoord2d(1.0,0.0); glVertex2d(0.5,0.5);
glTexCoord2d(0.0,0.0); glVertex2d(-0.5,0.5);
glEnd();[/cpp]

Does anyone know why it would? I've flipped the texture coordinates.

You can set actual numbers to each favorited item by selecting it in the favourites menu and pressing a number, that may work better than a macro. So then you just press the number you set the item to to equip it, no need to even open the menu.

[QUOTE=Mordi;35565462]Does anyone know why it would?[/QUOTE]
glTexImage2D expects the pixel data to start at the lower-left corner, DevIL gives you upper-left data.
The pixel rows are reversed.

Thanks, thats some very useful info, still, I would like to make a macro to get all my armor off in one keystroke.

Edit: Found the problem, $ was missing before the key declaration and sleeps were missing between keystrokes.

Why won't this display two text boxes? (Python) Also I clearly defined this class with one argument, yet I get an error when I do App(root)

I'm attempting to save a file using the dialog boxes provided by the Win32 API. This code works fine except for one thing; upon calling GetSaveFileName() it somehow jumps back to where my save function was called from, then calls it again... I can't really explain it but the end result is that after you close the first Save File dialog, another one opens. I really have no idea what's going on here, from what I've seen online my code is fine.
[cpp]OPENFILENAME ofn;
ZeroMemory(&ofn, sizeof(OPENFILENAME));

wchar_t filename[MAX_PATH] = L"";

ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = NULL;
ofn.lpstrFilter = L"OBJ Files (*.obj)\0\0";
ofn.lpstrFile = filename;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT;
ofn.lpstrDefExt = L"obj";

if(GetSaveFileName(&ofn))
{
char file[MAX_PATH] = "";
WideCharToMultiByte(CP_UTF8, 0, filename, MAX_PATH, file, MAX_PATH, NULL, NULL);

std::cout << "Saving to " << file << std::endl;
}[/cpp]
Any ideas?

Okay here's my python problem:

from Tkinter import *

class Output:
    def __init__(self,master):
        self.u=Text(master,width=40)
        self.u.grid(row=0,column=0)
        self.v=Button(master,text="Add text",command="Write")
        self.v.grid(row=1,column=0)
    def Write(self):
        self.u.insert(1.0,"Meh")

root=Tk()
output=Output(root)
root.mainloop()

Now it opens an empty text window. How do I make the button work in "real time" ?

Edit:

Found it, Write instead of "Write"

Also, how do I separate interface and inner workings? Do I create an Interface class and an Inner Workings class?

Does anyone know of any articles/tutorials on how to set up a game engine? I am talking about the handling of gamestates, loading, objects and so forth. I'm using C++, but that shouldn't matter. I can't seem to find what I'm looking for through googling.

I'd say go with something like Irrlicht, and try the rest out for yourself. The tutorials for it are pretty good too, and when you dig into the API documentation, there's LOTS of goodies in it for you.
And yes, it's C++ and fully namespace'd.

[Silentfood]

A simple Lua question here.

I have code similar to this.

local globe = {}
local listOfSpeeches = {}

table.insert( globe, {hi = "hello", bye = "bye"})
table.insert( globe, {"1", "2", "3"})

listOfSpeeches["greetings"] = globe[1]

How would one delete the table containing "hi and bye", across multiple arrays that might have this inside it?

edit:
this isn't for anything in gmod, btw.

I want to set up my own little game engine. Not going to create a full, usable engine, but just make a system to see how it could be done. I've already got OpenGL running, and loading and rendering sprites done. Now I will flesh it out and handle it in an object-oriented way.

I found one nice article that fits me well: [url]http://gamedevgeek.com/tutorials/managing-game-states-in-c/[/url]

[WTF Nuke]

I am developing a co-op game, and I just found out that if someone closes the connection on a UDP socket, the server receives 0 as the return from recvfrom(). How does it do this? Because I get about 30 packets where the server says recfrom() returns 0. Does it send a certain packet that is called at closesocket() or WSACleanup()? And if so, does I get the information of the person who sent it (the IP, etc?).

Anyone experienced with C++ here?

I moved all the game-engine setup from my main.cpp to a different class, and I am having trouble with one thing:
[cpp]glutDisplayFunc(Draw);[/cpp]

Freeglut doesn't like me doing this. This is the error I get:
[quote]Error: 'GameEngine::Draw': function call missing argument list; use '&GameEngine::Draw' to create a pointer to member
Error: IntelliSense: argument of type "void (GameEngine::*)()" is incompatible with parameter of type "void (*)()"
[/quote]
I guess this happens because whereas before, the draw-function was static. Now however, it's a function in an instantiated class.

Does anyone have any clue as to how I can make this work?

Edit: It turns out this is impossible to do... [url]http://bytes.com/topic/c/answers/441511-registering-glut-callback-c[/url]

but when using the template i can only use code the example gives me, if i try to input anything not used in the template then it errors.

[QUOTE=WTF Nuke;35582452]I am developing a co-op game, and I just found out that if someone closes the connection on a UDP socket, the server receives 0 as the return from recvfrom(). How does it do this?[/QUOTE]
There's no such thing as a UDP connection, and looking at the manpage, I don't see anything that would make recvfrom() return 0 when called on a UDP socket. (If it were a nonblocking socket and no data were available, it'd return -1 with errno set to EAGAIN or EWOULDBLOCK.)

[WTF Nuke]

That's the odd thing, it is blocking and it says recvfrom() returns >0 when someone disconnects (but only when they disconnect via forcing the program to shut down, not disconnecting that tells the server that you dc'd).

[Wyzard]

Are you sure you're using UDP and not TCP?

[WTF Nuke]

Yes.

By the way, what's the story behind "ilConvertImage()"?[/QUOTE]

I'm using DevIL with OpenGL, so for consistency I'm making sure everything is in RGBA format. Input images aren't necessarily, so I convert them. I'm calling convert on every image (even the ones that are already RGBA) because I couldn't find any way whatsoever of determining the current image format.
