What do you need help with? Version 1

[Dr Magnusson]

Ah, thanks. I misunderstood the concept of static then.

Any suggestions for what I might use to achieve my goal?

[animorten]

A static global variable is private to a .cpp file. You can declare it as
[cpp]
extern unsigned char Error;
[/cpp]
in the header and define it
[cpp]
unsigned char Error = 0;
[/cpp]
in ScriptCom.cpp

[Dr Magnusson]

Awesome, works like a charm. Thanks!

Having some problems with C++. Coming from C#, I fuck up most of the syntax. Here's my code so far.
[b]Main.cpp[/b]
[cpp]#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <iostream>

int main()
{
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "WinterEscape");
sf::Image Tex(32, 32, sf::Color::White);
Entity Ent;
Ent.Sprite::SetImage(Tex);

while (App.IsOpened())
{
sf::Event Event;
while (App.GetEvent(Event))
{
if (Event.Type == sf::Event::Closed)
App.Close();
}
App.Clear(sf::Color(40, 70, 125));
Ent.Draw(App);

App.Display();
}

return EXIT_SUCCESS;
}[/cpp]
[b]Entities/Entity.cpp[/b]
[cpp]#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <iostream>

class Entity
{
public:

sf::Sprite Sprite;

Entity()
{
Sprite = sf::Sprite();
}

~Entity()
{
}

void Draw(sf::RenderWindow App)
{
App.Draw(Sprite);
}
};[/cpp]
It whines about not being able to find the class name "Entity", so apparently it doesn't read the Entity.cpp file. How do I fix this?

[cpp]#include "Entities/Entity.cpp"[/cpp]
Says:
[quote]Cannot open include file: 'Entities/Entity.cpp': No such file or directory[/quote]

[Wyzard]

You don't include .cpp files from other .cpp files. Put the class definition in a header file (e.g. Entity.hpp) and include that. The implementation of the class's methods goes in Entity.cpp.

Syntactically that #include looks right, though. If it can't find the file then it's something with the paths in your project. Where is that Entities directory located?

Thanks but I found out that when I compiled sfml-system, it had named it libsfml-system-d.dll.a so i just removed the .dll part so that it could find it. Thanks anyways Chris :)

Nevermind, I rewrote the whole project using headers and now it all works :buddy: Thanks!

I wonder why it did that... how strange! Ah well, glad to hear it's working.

[awfa3]

Yea it was pretty confusing

[q3k]

Since I'm absolute shit with C++, I can't figure out why [url=http://pastie.org/private/8vqpfvepggo0oupnn2ww]this[/url] code crashes when the function ends and the runtime calls the destructor of the Elements vector. Stack trace:
[img]http://imgur.com/tUj6V.png[/img]

What am I doing wrong?

(also, yes, the code is messy and needs some stupid little optimizations like not calling .size() every time. But right now I just want to get it to work.)

[ZeekyHBomb]

What's the crash message?

And why are you allocating Elements.size() / 3 GLuints, but stuff in Elements.size() elements?
Instead of using an index to go through each index, you could also use an iterator for the m_* vectors.
And even more efficient: a std::memcpy for the Elements-vector (since it's a POD type).

Also be careful when passing a this-pointer to other functions from the constructor.

[q3k]

[QUOTE=ZeekyHBomb;26939039]What's the crash message?[/QUOTE]
Breakpoint encountered at HeapFree in _free_base @free.c.

[QUOTE=ZeekyHBomb;26939039]And why are you allocating Elements.size() / 3 GLuints, but stuff in Elements.size() elements?[/QUOTE]
Because I'm a fucking retard? It doesn't crash anymore now - I guess I just overflowed the heap like hell.

Oh, I didn't know about that.

Oh, that is awesome, I had no idea. I guess I really need to read up more about the STL.

Anyhow, fixed. Thanks a bunch!

[WTF Nuke]

Why can't I compare the getf() values? lowestfscore somehow always wins, even though no value is above 255.
[cpp]ctile * lowestfscore = new ctile;
lowestfscore->set(255, 255);
for(std::list<ctile *>::iterator i = openlist.begin(); i != openlist.end(); i++)
if((*i)->getf() < lowestfscore->getf())
lowestfscore = *i;
[/cpp]

Strip down your code to a barebone testcase and post that; there's not enough information in your currently posted code.

Yeah sorry about that, I coded that when I was tired. Bad idea. Anyway I'll make a standalone version with better documentation, just give me a bit.

Because Khronos seems to have fun deprecating everything from version to version, so people stop giving a fuck if method x is deprecated, and they're right.
