General / Handling time to delay?

« on: January 09, 2011, 08:33:29 pm »

Hi all.

I have a little game with a shooting feature I want to hold down a button to shoot but I don´t want it to shoot all the time, so can I use sf::Clock to just make it wait between all generating shots?

Graphics / use shapes in vector

« on: January 04, 2011, 10:05:46 pm »

I have a problem.

I have a class method where I declare a new Shape. i want to stack this in a vector.

Code: [Select]

#include <SFML/Graphics.hpp>
#include <iostream>
#include <vector>

class Circle : sf::Shape
{
    private:
    sf::Shape circle;
    int radius;
    std::vector <Circle*> circles;
    int x;
    int y;
    public:
    void generateCircle();
    void setValues(int x, int y);
    void draw(sf::RenderWindow& App);
    Circle();
};



and the method

Code: [Select]



void Circle::generateCircle()
{
    Circle* circle = new Circle;
    circles->sf::Shape ?
    circles.push_back(circle);
}

how can I declare the shape in to the vector?

Hello!

I am trying to use std::vector stl too make a little shootergame. But I don´t know how to save a sprite to a vector.

I have

Code: [Select]


#include "Sprite.h"

Bullet::Bullet()
{
    x = 100;
    y = 100;
    if(!Image.LoadFromFile("bullet.jpg"))
    {
        //Error
    }
}

void Bullet::shoot()
{
    Bullet* bullet1 = new Bullet;
    bullet1->SetImage(Image);
    bullets.push_back(bullet1);
}

void Bullet::drawBullet()
{
    bullet.SetImage(Image);
}

void Bullet::generateBullet()
{
    Bullet* bullet = new Bullet;
    bullets.push_back(bullet);

}
void Bullet::draw(sf::RenderWindow& App)
{
    App.Draw(bullet);
}



But the I can´t save the file to the vector who are vector<Sprite*> bullets; in bullet class.

I want to App.Draw(bullets);

What do I need to do?

Hello

Is there away you can have many different events?

Like different classes and functions.

sf::Event Run;
sf::Event Meny;

Like that?

Graphics / Drawing Images problem

« on: January 25, 2010, 07:49:33 pm »

Hello

I´m on a school projekt to do a little game. But I´m stuck. I don´t know how to draw images when they are in another file. The compiler says that Draw it´s no a function to the class. Here is the soruce for better description.

Code: [Select]

view.cpp #include <SFML/Graphics.hpp>
#include <fstream>
#include <iostream>

using namespace sf;
using namespace std;

class Map: public Sprite
{
    private:
    sf::Sprite sprite;
    char num;
    char level[12][12];
    int height;

    //Create image
   sf::Image blockImage;
   sf::Image groundImage;
   sf::Image wallImage;

    public:
    void openFile();
    void updateMap();
    void loadAllImages();
    void update();
    Map();

};


void Map::openFile()
{
    height = 0;

    //Read textfle (2D char array)
   ifstream file;
   file.open("level.txt");


   std::string line;

    while(getline(file, line))
   {
      for(int width = 0; width < 12; width++)
      {
         level[height][width] = line.at(width);
      }
      height++;
   }
   //Close file stream
   file.close();
}
void Map::loadAllImages()
{
   //Create Sprite
   Sprite blockTile(blockImage);
   Sprite groundTile(groundImage);
   Sprite wallTile(wallImage);
}

void Map::updateMap()
{

    //Scroll through level and display corresponding image of tile
      for(int y = 0; y < 12; y++)
      {
         for(int x = 0; x < 12; x++)
         {
            num = level[y][x];

            if(num == '1')
            {

               this->sprite.SetPosition(x*50, y*50);
               this->sprite.SetImage(blockImage);

            }
            else if(num == '2')
            {
               this->sprite.SetPosition(x*50, y*50);
               this->sprite.SetImage(groundImage);
            }
            else if(num == '3')
            {
                this->sprite.SetPosition(x*50, y*50);
                this->sprite.SetImage(wallImage);
            }
         }
      }
}


and the other file that contains main function.

Code: [Select]

#include <SFML/Window.hpp>
#include <SFML/System.hpp>
#include <iostream>
#include <fstream>
#include "view.cpp"

using namespace sf;
using namespace std;


int main()
{

    Map map;
    map.openFile();

    map.updateMap();
    //Display using SFML
    //Render Window
    sf::RenderWindow App(sf::VideoMode(640, 480), "Shoot");
    //Game loop
    while (App.IsOpened())
    {
      sf::Event Event;
      while(App.GetEvent(Event))
      {
         if(Event.Type == sf::Event::Closed)
         {
            App.Close();
         }
      }
    map.loadAllImages();


    App.Draw();
    // Clear the screen with white color
    App.Clear(sf::Color(0, 0, 255));
    //Display sprites
    App.Display();
   }
   return EXIT_SUCCESS;
   //*/
}


Hope you can help me
