i really had no idea a standard c++ std::vector could hold a sfml sprites object

thank you for your help

going off your code

sf::Sprite enemy;

how would i set the postion of sprite 4

say

enemy[3].setpostion(x,y);

??

thanks again

Hello simple newbie question here

If you were making the game pacman

There are say 20 badguys (ghosts)

Should i be creating 20 different sprites

    sf::Texture txBadPlayer;
    if (!txBadPlayer.loadFromFile("badplayer.png"))
    {
       return 0;
    }
    sf::Sprite spBadPlayer;
    spBadPlayer.setTexture(txBadPlayer);

 sf::Texture txBadPlayer2;
    if (!txBadPlayer2.loadFromFile("badplayer.png"))
    {
       return 0;
    }
    sf::Sprite spBadPlayer2;
    spBadPlayer2.setTexture(txBadPlayer2);
 

times 20

or should i use arrays or something ?

ps.. all bad guys have the same picture, but different movement

please could someone point me in the right direction
thanks

I thought i would post to help others, this works with sfml 2.1 codeblocks c++

#include <SFML/Graphics.hpp>
#include <sstream>



int main()
{

    sf::Font font;
    font.loadFromFile("arial.ttf");

    sf::Text text;
    text.setFont(font);
    text.setPosition(100,100);
    text.setCharacterSize(34);
    text.setColor(sf::Color::Red);


    sf::Clock clock; // starts the clock
    sf::Time elapsed1; // set time object

    int intSecondsCounted;

    std::stringstream ss;



    sf::RenderWindow window(sf::VideoMode(800, 800), "Hag");
    // run the main loop

    while (window.isOpen())
    {
        // handle events

        sf::Event event;
        while (window.pollEvent(event))
        {
            if(event.type == sf::Event::Closed)
                window.close();
        }



        elapsed1 = clock.getElapsedTime();


        ss.str(std::string()); //clear the string
        ss << elapsed1.asSeconds();
        ss << std::endl << "Seconds Since I Started Counting";
        text.setString( ss.str().c_str() );

        window.draw(text);
        window.display();
        window.clear();

    }

    return 0;
}

just incase anyone wants to try this themselves

i have decided, tile mapping is right for my mini game and also tile map collision

if you take pacman as a sample

anyways

i have made some very basic code.. which will read a image, of 800 by 800 pixcels, cut it in to 32 by 32 squares and display all the squares in orders

which is below, from this i hope to make 1 screen per level games, whereby i used a txt file, which states which tiles can be passed over

the code is below

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



int main()
{
    sf::Texture texture;
    if (!texture.loadFromFile("hag.png"))
    {
       return 0;
    }

    sf::Sprite box1;
    box1.setTexture(texture);

    sf::RenderWindow window(sf::VideoMode(800, 800), "Particles");

    // run the main loop
    while (window.isOpen())
    {
        // handle events
        sf::Event event;
        while (window.pollEvent(event))
        {
            if(event.type == sf::Event::Closed)
                window.close();
        }


        sf::Time elapsed = clock.restart();
      //  std::cout << (elapsed.asSeconds()*97680) << std::endl;


        window.clear();

        int lngRow = 0;
        int lngCol = 0;

        while(lngCol < 800)
        {
            lngRow = 0;
            while(lngRow < 800)
            {
                box1.setPosition(lngRow,lngCol);
                box1.setTextureRect(sf::IntRect(lngRow, lngCol, 32, 32));
                window.draw(box1);
                lngRow = lngRow + 32;
            }
            lngCol = lngCol + 32;

        }
        window.display();

    }

    return 0;
}

this is sfml as far as i know

i am only using sfml, i only know sfml ~(slightly)

i admit, the same methods may be used in other frameworks, lib, engines etc

but why can i not just have a tiny bit of advice from an expert

it will save me a great deal of time, and i do not want to know how to do it

i'm not asking you to code it.. just point in me in the right direction

i'm sorry if its not in the wrong part of the forum, i'm sorry your clearly god

and a mere mortal as myself should not even speak to you

why don't you get a life, or better yet, be the big man and point out my bad grammar or spelling

thanks for your help anyways

Graphics / mario 1 style advice

« on: November 02, 2014, 04:03:12 am »

hello

i am trying to make a mario clone for fun

i have the sprite running, and a png as a large background image and the screen moving, if i run to which ever end of screen

ofcouse, he runs thur everything at the min

if i wanted mario to jump on to a box(like in the normal game)

should i be going down the route of

map tiles.. (to load the whole background image)
and then map tile collision

which i guess works on the system of

so................

you load the background image (mario level background), you load and display as tiles (chopping your image in to boxes on the fly)

and also you have a collision text file, with 0 and 1

and a loop, which checks if that tile, related to a 0 or 1

is that right.. or am i doing this the hardway ?

thank you

« on: September 30, 2014, 12:22:06 am »

Thank you for your answer, i will use your shape code thank you

i am having problems find the height of the window.. the bottom of the window

in order to say

when the shape.postion (x or y) gets to (bottom off window) - change direction

the 800 is a guess of the windows boarder

i dont know how to get the window boarder at the bottom, or width ?

any ideas

Window / simple question - getting the height of the window

« on: September 30, 2014, 12:03:29 am »

I am trying to make a shape bounce from the top of the window to the bottom and back, over and over

i can not get the height correct, so i guessed at 800

any ideas

thanks

------------------------------------------------------------------

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

int main()
{

bool bShouldObjGoDown = true;


sf::RenderWindow window(sf::VideoMode(800, 800), "SFML Application");
// ,sf::Style::Fullscreen
window.setFramerateLimit(60);


sf::CircleShape shape;
shape.setRadius(40.f);
shape.setPosition(1, 1);
shape.setFillColor(sf::Color::Cyan);



while (window.isOpen())
{
    sf::Event event;
    while (window.pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
        window.close();
    }
    window.clear();
    window.draw(shape);
    window.display();

    if(bShouldObjGoDown == true)
    {
        shape.move(0,5);
    }

    if(bShouldObjGoDown == false)
    {
        shape.move(0,-5);
    }

    std::cout << shape.getPosition().y << std::endl;

    if(shape.getPosition().y < 1)
    {
        bShouldObjGoDown = true;
    }
    if(shape.getPosition().y > 800)
    {
        bShouldObjGoDown = false;
    }

}

}
 

end

on the part

if(shape.getPosition().y > 800)

i want the 800 to be the botton of the window

i want the ball to bounce off the boarders

please help this is driving me crazy

thank you
