General / Sprites inside a Class

« on: April 11, 2016, 03:48:55 pm »

hi, i have created a class called "Player"

in its header
"Player.h"

#ifndef PLAYER_H
#define PLAYER_H
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
#include <SFML/System.hpp>

using namespace std;

class Player
{
public:
 sf::Sprite sprite(){
         sf::Texture texture;
            texture.loadFromFile("gunship.png");
            texture.setSmooth(true);
        sf::Sprite playersprite;
        playersprite.setTexture(texture);
        return playersprite;        
}
 

its cpp file

Player.cpp

#include "Player.h"
Player::Player()
{

}
 

what i am trying to do is to create an object from this class from another cpp file called

newMap.cpp

#include "NewMap.h"
#include "Player.h"
#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>
int mapPlayers()
{
    sf::RenderWindow map1(sf::VideoMode(1180, 600), "GUNSHIP", sf::Style::None);
            sf::Font font;
            if (!font.loadFromFile("emulogic.ttf"))
            return EXIT_FAILURE;

    sf::Text gametitle("GUNSHIP", font, 54);
            gametitle.setPosition(300,50);

 Player p1;                //created an object p1 from the class player

while(map1.isOpen())
            {
                map1.draw(gametitle);
                while(map1.pollEvent(event))
                {

                }
            map1.draw(p1.sprite());     //i want to draw the sprite of the object P1 from the class Player
            map1.display();
            }
    return 0;
}
 

in the main.cpp

#include "NewMap.h"
 main()
{
mapPlayers();
return 0;
}
 

my code does not have throw an error but it crashes everytime i execute it.
the first result that i had was a blank white rectangle. please help

Hello everyone, i am trying to display a window for 3 seconds,after that it closes. yet why does the window displays on random amount of time. it does not display the way i wanted to. Can anyone please enlighten me of my rather stup!D error.  it does display the window but not exactly 3 seconds. sometimes it jumps to 3.xx to greater than 3 seconds. can somebody enlighten me with this please?

sf::Clock clock;
            sf::Time limit = sf::milliseconds(3000);
            sf:: Time elapsed;

...loop...
elapsed=clock.getElapsedTime();
             while(window5.pollEvent(event))
                {
                    //std::cout<<elapsed.asMilliseconds()<<std::endl;
                    if(elapsed.asMilliseconds()>limit.asMilliseconds())
                            {
                                window5.close();
                            }
                }

Window / BACKSPACE PROBLEM(please read before condemning this as duplicate :) )

« on: March 24, 2016, 05:04:07 am »

I've been reading about this for 4 hours both docs and threads here but I was not able to make this work properly . i am posting this as new topic again because the threads i went to i guess are dead. I just simply want to ask max of 8 character input and delete characters when backspace is pressed. somehow i got it working but:

• it deletes the last character, but it replaces it with the backspace character value " ".

question is: what should i do so that the backspace character value is not inserted on the string?

here is my code:

 if (event.type == sf::Event::TextEntered)
                            {
                                if((event.text.unicode < 128)&& playerInput.getSize()< 8 )
                                    {  playerInput.insert(playerInput.getSize(), event.text.unicode);
                                       playerText.setString(playerInput);
                                    }
                            }
                    if(event.type == sf::Event::KeyPressed)
                                    {
                                        if(event.key.code == sf::Keyboard::BackSpace)
                                            {playerInput.erase(playerInput.getSize()-1,2);
                                            playerText.setString(playerInput);}
                                    }
