Yes parallax scrolling was the term that i am searching for! But can i make it with a view without moving them around ? i have a free world space ? and its to huge for move all stars separately around ?

i dont understand how

#include "Background.h"

Background::Background(b2World *g_world, sf::RenderWindow &g_window ){

        int size = 50;


        for(int i = 0; i != size; i++){

                float rand_size = frandom(2.f,6.f);
                float rand_positionX = frandom(-500.f,500.f);
                float rand_positionY = frandom(-500.f,500.f);

                sf::RectangleShape t_shape;

                t_shape.setSize(sf::Vector2f(rand_size, rand_size));
                t_shape.setFillColor(sf::Color::White);
                t_shape.setPosition(sf::Vector2f(rand_positionX, rand_positionY));

                StarsList.push_back(t_shape);

        }

}
void Background::Update(sf::RenderWindow *g_window){
        sf::View cam = g_window->getDefaultView();
        float speed = 0.0000033f;


        std::list<sf::RectangleShape>::iterator I;
        for(I = StarsList.begin(); I != StarsList.end(); ++I){
                (*I).move((*I).getPosition().x * cam.getCenter().x * speed, (*I).getPosition().y * cam.getCenter().y * speed);
        }
}
void Background::Draw(sf::RenderWindow *g_window){
        std::list<sf::RectangleShape>::iterator I;
        for(I = StarsList.begin(); I != StarsList.end(); ++I){
                g_window->draw((*I));
        }
}

Graphics / [C++] Moon and Stairs shift ?

« on: April 11, 2013, 09:04:19 pm »

Hello

How can i shift stars and moons in a scene ?

Example:

The blue thing is the player in two different situations.
Left: there are some stars behind the moon
Right: only the player(the view) moves a bit to the right and i can see more stars

I done that it work but now i have another problem
if anyone User disconnected the server shuting down but there is nothing like shutdown oô in code

The server Loop

Code: [Select]


void Main::Loop(){
	while(Run){
		if(Selector.wait()){
			if(Selector.isReady(Server)){
				sf::TcpSocket* User = new sf::TcpSocket;
				if(Server.accept(*User) == sf::Socket::Done){
					sUser *theUser = new sUser;

					theUser->Client = User;
					theUser->State = 0;
					theUser->Remove = false;

					UserList.push_back(theUser);
					Selector.add(*User);
					cout << "User connected" << endl;
				}
			}else{
				for(std::list<sUser*>::iterator it = UserList.begin(); it != UserList.end(); ++it){
					sUser& User = **it;
					if(Selector.isReady(*User.Client)){
						sf::Packet Data;
						sf::TcpSocket::Status State = User.Client->receive(Data);
						if(State == sf::Socket::Done){
							HandleData(Data,User);
						}else if(State == sf::Socket::Disconnected){
							User.Remove = true;
							PublicMessage(User.ClientName + " has left the Chat.");
						}else if(State == sf::Socket::Error){
							cout << "Error" << endl;
						}
					}
				}
				UserList.remove_if(CanRemove);
			}
		}
	}
}

OHH ifound it self

i have forgett to remove the client from selector

Code: [Select]

Selector.remove(*User.Client);
and add the client RIGHT to the selector

Code: [Select]

Selector.add(*theUser->Client);

all is okay CLOSED

I do every time this.
in a Thread

Code: [Select]


for(std::list<sUser*>::iterator it = UserList.begin(); it != UserList.end(); ++it){
					if(Selector.isReady(*User.Client)){
						sf::Packet Data;
						if(User.Client->receive(Data) == sf::Socket::Done){
							HandleData(Data,User);
						}
					}

}

Graphics / Better FPS drawing 10.000 sprite

« on: March 11, 2012, 10:00:39 pm »

Here and example

i have an Area 1000x1000.
I create now 100 sf::Images

Code: [Select]


for(int x = 0; x != 100; x++){
    sf::Image *Chunk = new sf::Image;
    Chunk->Create(1000,1000);
}

Then i add all the Objects that are on this area schould be with

Code: [Select]


Chunk->Copy(Exampleimage,X,Y,IntRect(0,0,Exampleimage.GetWidth(),Exampleimage.GetHeight()),true);

then convert to the sprites and add too sprite list

Code: [Select]

Texture *tChunk = new Texture;
tChunk->LoadFromImage(Chunk,IntRect(0,0,1000,1000));
Sprite *sChunk = new sf::Sprite(*tChunk);
sChunk->SetOrigin(0,0);
sChunk->SetPosition(sf::Vector2f((float)xCount,(float)yCount));
BackgroundChunks.push_back(sChunk);

generate new position for the next "chunk"

Code: [Select]

		xCount += 1000;
		xCounter++;
		if(xCount == 5000){
			xCount = -5000;
			yCount += 1000;
			xCounter = 0;
			yCounter++;
		}

and then Draw the 100 Sprites

Code: [Select]

for(list<sf::Sprite*>::iterator IT = BackgroundChunks.begin(); IT != BackgroundChunks.end(); IT++){
		_RenderWindow->Draw(**IT);
	}

its very simple
