Graphics / How to rotate sprite, keeping the original position?
« on: June 26, 2014, 11:45:08 pm »
How to rotate sprite, keeping the original position? Sprite position changes every time. It goes to ~ 300 degrees. 
Sprite* square;
....
square->SetRotation((float)rand()%360);
....
square->SetRotation((float)rand()%360);

Network / How read recive data? (const void*)
« on: March 26, 2014, 07:10:57 pm »
Hello! I need to read the incoming packets.
I can not make it through sf::Packet, since the structure of the package is not known.
I need to convert the received packet data(const void*) to "classical" set bits in hex format. (example: 00:00:00:04:00:00:00:0c:68:65:6c:6c:6f:20:73:65:72:76:65:72)
ps: by TcpSocket

Graphics / Re: How to create a copy of the class?

Graphics / How to create a copy of the class?
« on: January 12, 2014, 06:35:49 am »
Greetings!
I want to make a base class Depictable for graphics that will hold my methods.
It inherits from sf :: Drawable.
How to make a class so that it is drawn?
except sf::RectangleShape* line = new Rectangle(sf::Vector2f(50, 10));
I want to make a base class Depictable for graphics that will hold my methods.

class Depictable: public sf::Drawable
{
...
public:
virtual ~Depictable() {}
private:
void draw(sf::RenderTarget& target, sf::RenderStates states) const {}
...
};
I want to do is an exact copy of the class sf :: RectangleShape.{
...
public:
virtual ~Depictable() {}
private:
void draw(sf::RenderTarget& target, sf::RenderStates states) const {}
...
};
class Rectangle : public Depictable, public sf::RectangleShape
{
public:
virtual ~Rectangle() {}
explicit Rectangle(const sf::Vector2f& size = sf::Vector2f(0, 0)) { setSize(size); }
};
and then draw it.{
public:
virtual ~Rectangle() {}
explicit Rectangle(const sf::Vector2f& size = sf::Vector2f(0, 0)) { setSize(size); }
};
Rectangle* line = new Rectangle(sf::Vector2f(50, 10));
line->setFillColor(sf::Color::White);
line->setPosition(100, 100);
app.draw(*line);
Naturally, the line is drawn.line->setFillColor(sf::Color::White);
line->setPosition(100, 100);
app.draw(*line);

General / Re: Question about destructors of some classes.
« on: May 18, 2013, 01:46:25 pm »Thanks, now I understand.The thread is still active, you have to manually call thread->terminate().No, you should not call terminate() in normal situations. sf::Thread::~Thread() invokes wait(), therefore it waits until the thread is finished. Just let your thread end regularly.
Concerning sf::TcpSocket, the base class destructor ~Socket() invokes close().
What is the "processing status"?Whether running launch()?
I would like to use a list of pointers to thread (std::list<sf::Thread*>), but i have to use a pair. (std::list <std::pair<sf::Thread*, bool /*isLaunched*/>>) or a map.

General / Question about destructors of some classes.
« on: May 18, 2013, 01:23:03 pm »
Good day.
I have a question.
Why destructors some classes:
sf::~TcpSocket, sf::~Thread
do not call methods:
sf::TcpSocke::disconnect(), sf::Thread::terminate()
?
When using them appear some discomfort, for example:
ps: And yet, it would be nice to add the processing status for threads. (sf::Thread::Status)

System / Re: SFML in the future.
« on: March 18, 2013, 11:16:04 am »...You do not understand me. I was referring to the cast to the parent class.
Example even have to SFML:
classes Shape, Sprite and Text are the methods of Transformable, so they inherit from him.
It follows from this that I can use methods getPosition() and I do not need to know which type is inherited particular instance Drawable.
for example:
void Object::Foo(sf::Transformable* transformable)
{
...
transformable->getPosition();
...
}
sf::Shape* rect = new sf::RectangleShape;
...
object.Foo(dynamic_cast<sf::RectangleShape*>(rect));
{
...
transformable->getPosition();
...
}
sf::Shape* rect = new sf::RectangleShape;
...
object.Foo(dynamic_cast<sf::RectangleShape*>(rect));

System / Re: SFML in the future.
« on: March 18, 2013, 10:21:08 am »I guess the question is: Will getLocalBounds and getGlobalBounds get moved to the parent class? Right?yep.
Quote
If so then the answer is no.This is problematic in my situation.
The two functions exist only for convenience and not all of the transformable would need those functions. Besides that it's very easy to add such functionality to a derived class, if you need them.
For example, I want to write a common function of demand for Drawable, but the methods of getGlobalBounds and getLocalBounds declared separately in each class (Shape, Sprite, Text, VertexArray?).
I make do with templates and type checking.((

Will there be moved methods getLocalBounds, getGlobalBounds to parent class?

Will there be any in the library of methods for process management and implementation of the singleton pattern?
