Graphics / Is there a way to take a capture of the map width and height?

« on: August 20, 2014, 03:17:46 pm »

Ok so what I want to do is save an image of the entire map to a file. The problem im having is it only saves what is shown in the window, I want it to save the entire height and width of the map not the window. I'm a bit unsure on how to go about doing this though, if it's even possible.

ah, i see, so what do I put in it? when I try to do:

str.window.create(str.vidM(700, 800), str.window.setTitle("window"));

It gives me errors

C:\Users\thund_000\Desktop\Pass Render Wimdpw\main.cpp|34|error: no match for call to '(sf::VideoMode) (int, int)'|

Window / Window won't show when passed from struct

« on: August 18, 2014, 06:11:19 am »

I am trying to put my window in a struct, I made this file as a test as my other file was huge, the program compiles but the window never appears, what's going wrong?

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

using namespace std;

struct Str
{
    Str(sf::RenderWindow& window, sf::VideoMode& vidM);

    sf::RenderWindow& window;
    sf::VideoMode& vidM;
};

Str::Str(sf::RenderWindow& window, sf::VideoMode& vidM): window(window), vidM(vidM)
{

}

void MAIN(Str &str);

int main()
{
    sf::RenderWindow win;
    sf::VideoMode vMode;

    Str str(win, vMode);

    MAIN(str);
}

void MAIN(Str &str)
{
    str.window;
    str.vidM.height = 800;
    str.vidM.width = 600;
    str.window.setTitle("Window");

    while(str.window.isOpen())
    {
        str.window.clear();
        sf::Event event;
        while(str.window.pollEvent(event))
        {
            switch(event.type)
            {
                case sf::Event::Closed:
                {
                    str.window.close();
                }
            }
        }
        str.window.display();
    }
}

General / Re: Collision help

« on: August 16, 2014, 01:26:31 pm »

Well i've been doing that, i try to get the left and right sides and top and bottom and I do get those things so that's not a problem but when i touch the square it sometimes acts like its slippery and goes around it, also if Im pressing a key and then press another direction key it will go to one of the corners of the square. other than that it does collide, so what could be going wrong and how can I fix it?

I am making some collision and it sort of works but it's not working as good as it should, its hard to explain but if you run the code you'll see what i mean.

Collision

//Get collision.
        if(rectToMove.intersects(redBlockSprite.getGlobalBounds()))
        {
            if(velocity.x < 0 && position.x < redBlockSprite.getPosition().x + redBlockSprite.getGlobalBounds().width)
            {
                cout << "Touched Right side" << endl;
                position.x = redBlockSprite.getPosition().x + characterSprite.getGlobalBounds().width;
            }
            if(velocity.y > 0 && position.y > redBlockSprite.getPosition().y - redBlockSprite.getGlobalBounds().height)
            {
                cout << "Touched Top" << endl;
                position.y = redBlockSprite.getPosition().y - characterSprite.getGlobalBounds().height;
            }

            if(velocity.x > 0 && position.x > redBlockSprite.getPosition().x - redBlockSprite.getGlobalBounds().width)
            {
                cout << "Touched Left Side" << endl;
                position.x = redBlockSprite.getPosition().x - characterSprite.getGlobalBounds().width;
            }
            if(velocity.y < 0 && position.y < redBlockSprite.getPosition().y + redBlockSprite.getGlobalBounds().height)
            {
                cout << "Touched Bottom" << endl;
                position.y = redBlockSprite.getPosition().y + characterSprite.getGlobalBounds().height;

Ok so i'm trying to make some collisions and im reading the API document and I see:

"sf::Vector2f point = ...;"

What goes after point?

Yeah, it's the test code when you follow the instructions to set it up:

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    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();
    }

    return 0;
}

Ok I forgot to take out lib in front of sfml, however I did that and I still get errors:

If I do JUST

I get these errors:

I don't understand what's going on here, I have Code Blocks 13.12 with MinGW, I downloaded the "GCC 4.7 TDM (SJLJ) - 64 bits" version of SFML and I followed the tutorial, here:

http://www.sfml-dev.org/tutorials/2.1/start-cb.php

exactly as it was shown and I get 3 errors. Here it what it says:

||=== Build: Debug in SFML Test (compiler: GNU GCC Compiler) ===|
\SFML-2.1\lib\libsfml-graphics||No such file or directory|
\SFML-2.1\lib\libsfml-window||No such file or directory|

||=== Build failed: 3 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|


What is wrong? I have Windows 8 64 bit.


Also here is this from the build log:

-------------- Build: Debug in SFML Test (compiler: GNU GCC Compiler)---------------

It says mingw32, do i need to download the 32 bit version of SFML?
