[QUOTE=esalaka;33333822]...Make the sprite a private member, then?[/QUOTE]
But then I'd have to make a private member for the sprite, for the leaning left image, for the leaning right image, for the thrusting forward image, the "backing" image and so on. Isn't there any other way that I can access things from player() in tick()?

[QUOTE=Swebonny;33356751]Put your lua file in a folder and then drag it to LÖVE.[/QUOTE]

Tried that, but I got errors. I even named it 'main.lua' I'll have to look it over. Thanks Swebonny.

I don't understand your problem; it should be the exact same code, except that you move the "type definitions" from the constructor to the class members.

If I did it the way (that I think) you're telling me to do, I would have to do something like this:
[cpp]Player::Player(double x, double y, bool alive, int frame, sf::Image img_pship_left_01, sf::Image img_pship_left_02, sf::Image img_pship_right_01, sf::Image img_pship_right_02, sf::Image img_pship_forward_01, sf::Image img_pship_forward_02)[/cpp]
...and so on with all the images I'd need, right? Or am I missing something here?

Well, that's one way of doing it, obviously. Show us how exactly you're doing it now so we can react better? (If it's already here, someone link me please)

[ZeekyHBomb]

There are not member variables, these are parameters.
Those would as well be destructed when the function returns.

You want member in the class
[cpp]class A
{
int thisIsAMemberVariable;
};[/cpp]

What or whom did you learn C++ from?

I'm writing an IRC bot in C#. Using the SmartIRC4Net library.
I'm trying to add a OnJoin event handler.
My code:

            irc.OnQueryMessage += new IrcEventHandler(OnQueryMessage);
            irc.OnError += new ErrorEventHandler(OnError);
            irc.OnRawMessage += new IrcEventHandler(OnRawMessage);
            irc.OnChannelMessage += new IrcEventHandler(OnChannelMessage);
            irc.OnJoin += new IrcEventHandler(OnJoin);

All of the code is fine, except for OnJoin, which results in the error "No overload for 'OnJoin' matches delegate 'Meebey.SmartIrc4net.IrcEventHandler'"
No clue what the problem/solution is.

Didn't you have to drag the FOLDER that [I]contains [/I]main.lua to Love?

[editline]20th November 2011[/editline]

If you're not interested in Love2d but just in running Lua, I too started reading exactly that today. I found [url]http://code.google.com/p/luaforwindows/[/url] to be working quite well. I think you'll be able to double-click .lua files if you install that. Otherwise you can run "lua main.lua" in a command prompt.

...Oh. From what I read online I had to include every variable in the class's declaration (and I didn't want to do that because it would result in a huge mess), but what you're telling me is that I don't?

Also whenever I have / get suggested / want to learn something new about C++ I just jump into Google and search for it, don't have a specific website I go to. I also have a book called "C++ Primer Plus (5th Edition)", but I only read it when I'm bored/at class/etc because googling usually gets me there faster without having to turn my closet upsidedown to get it out of there :v:

What would be fastest?

m_data1 = 0;

The OnJoin event expects a JoinEventHandler delegate. So you need to do

[csharp]irc.OnJoin += new JoinEventHandler(OnJoin);

void OnJoin(object sender, JoinEventArgs e)
{
}[/csharp]

The first one becomes a call to the constructor for each member, the second one becomes a call to the default constructor and then the copy constructor.

The first one is potentially faster.

The former directly constructs the objects.
The latter uses the default constructor, followed by the assignment operator.

It might get optimized away for build-in types, but it'd be a tad faster with 'complex' types.

I think you also need to build SFML against the static library then.

Or you can just supply the runtime dlls along your program; not sure on the license there though.

[QUOTE=ROBO_DONUT;33356333]Do you need a documentation to double-click a '.msi' file in Windows? No, because it's simple, consistent and common.
In Linux, you build software with './configure && make -j5 && sudo make-install'. It then installs to /usr/local/, unless you've overridden the install path for configure and make using the 'PREFIX' environment variable and '--prefix' argument.

The issue isn't lack of documentation, the issue is that you don't know how to function in a unix-like environment.[/QUOTE]

I suppose that's right. A double click is so much simpler. The trade off is the ability to customize, and I guess that's what Linux does best.

Anyway, I've run 'make install' and it makes cygcaca.dll, not libcaca.dll (it does however make libcaca.dll.a but I don't think that's related).

Do I have to cross compile? What would the "host" be set to?

While MinGW and Cygwin both provide unix-like build environments, MinGW runs natively, while Cygwin provides full posix emulation through libcygwin. So if you want to build native binaries (if it's possible for that particular library), you'll need to build with MinGW instead of Cygwin.

My socket seems to not be sending anything, I make one client and on the second connect to the server the server doesn't send the entities but does send the map name and etc. I even tried with 2 separate clients.
