General / Re: Sprites inside a Class

lets cut the discussion short.

when you say "You need to keep track of your texture untill the destruction (or the use) of your sprite."

how should i implement that in my code???

yeah my mistake on the term..i admit. but if you say that this is a syntactic error, then my program shouldnt have  executed.. the window i created should not have displayed..

nicox11. you are not really providing answers. what you are pointing here is if i have enough skills on c++ and sfml, well i admit i dont, THAT IS WHY I ASK QUESTIONS..

you should maybe go back to the basics.

what i was asking is how to make the sprite() function work properly. i am sorry if i lack basic coding competencies like you said, but you see i am a newb. i only use what i see on tutorials and those that i tried and worked as long as it worked.

im sorry im still a beginner that is why.

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

hi exploiter, i get a little bit confused when you say:

"you get the elapsed time once","all you do is compare two fixed values" and " you call getElapsedTime before the loop"

are you telling me what i should do, or what my mistake are??

« on: March 28, 2016, 08:10:27 am »

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();
                            }
                }
window5.display();
...end loop...

Posting code already posted = helpful
Trying to explain = useless

You see i'm really new to programming, sorry that i forgot to thank you, you explained it well but i didnt know how to implement it...now im getting it.

Thank you bitano.. got it working.. Thank you for helping beginners like me, i really learn very slow. Thank you for your help.

if (event.text.unicode == '\b') // handle backspace explicitly
                                {
                                    playerInput.erase(playerInput.getSize()- 1, 1);
                                    playerText.setString(playerInput);
                                }
                            else // all other keypresses
                                {
                                    playerInput += static_cast<char>(event.text.unicode);
                                    if((event.text.unicode < 128)&& (playerInput.getSize()< 8 ) )
                                            playerText.setString(playerInput);
                                }

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);}
                                    }

i dont really get what "handle explicitly", how do i do it? im just knew in SFML, thats why, i read the documentation on .erase(position, count o char to erase), could you please give me a clearer hint that i could understand.


 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()-1,1);
                            }

this one works it does delete the last character but the backspace value remains.

if "HELLU" -press backspace "HELL" -press O "HELL 0".

deletes only once.

Hi, everyone i hope this thread is not dead yet, i just want to ask why is my code(below) only delete the last character when it reaches the total size of character input.

if (event.type == sf::Event::TextEntered)
                            {   //handle user input     !!works properly
                                if((event.text.unicode < 128)&& playerInput.getSize()< 8 )
                                    {   
                                       playerInput.insert(playerInput.getSize(), event.text.unicode);
                                       playerText.setString(playerInput);
                                    }
                                //erase on backspace press     !!does not work properly?what is wrong with it??
                                if(event.text.unicode == '\b')
                                    {
                                        playerInput.erase(playerInput.getSize() -1,1);
                                    }
                            }
what i want to do is ask for input(max of 8 characters), and delete when backspace is entered.
