General / What am I doing wrong here ?

« on: November 11, 2009, 11:48:51 am »

I am trying to make a sprite point to the place where I click but it just seems to point upward when I click somewhere, I know it updates the sprite cause in the beginning stage its about 45 degrees and then when I click it points upwards.

Code: [Select]


// The class which needs to update
Cockpit::Cockpit()
{
std::cout << "Cockpit" << std::endl;
    turningspeed = 4;
direction = 0.f;
if (!Image.LoadFromFile("Cockpit.png"))
{
std::cout << "Error loading image file !" << std::endl;
}
sprite.SetImage(Image);
sprite.SetScale(0.5f,0.5f);
float Width  = sprite.GetSize().x;
float Height = sprite.GetSize().y;
sprite.SetRotation(direction);
sprite.SetCenter(Width/2, Height/2);
sprite.SetPosition(400.f,300.f);
x,target_x = 400;y,target_y,y = 300;
}

void Cockpit::Think(sf::RenderWindow &Render)
{
direction = atan2(target_y-y,target_x-x)*180/PI;
sprite.SetRotation(direction);
}
// Inputmanager
void InputManager::Think(sf::RenderWindow &Render)
{
const sf::Input &Input = Render.GetInput();
mouse_x = Input.GetMouseX();
mouse_y = Input.GetMouseY();
mouse_right = Input.IsMouseButtonDown(sf::Mouse::Right);
sprite.SetPosition(mouse_x,mouse_y);

if (mouse_right == true)
{
hold_right += Render.GetFrameTime();
}
if (mouse_right == false && hold_right > 0)
{
if (hold_right >= 0.5)
{
hold_right = 0;
std::cout << "Window" << std::endl;
} else {
hold_right = 0;
player->Goto(mouse_x,mouse_y);
}
}

if(Render.GetEvent(Event))
{
if (Event.Type == sf::Event::Closed)
Render.Close();

if((Event.Type == sf::Event::KeyReleased) && (Event.Key.Code == sf::Key::Escape))
Render.Close();

if (Event.Key.Code == sf::Key::F1)
{
sf::Image Screen = Render.Capture();
Screen.SaveToFile("screenshot.jpg");
}
}

}


Anybody knows what I am doing wrong ?

Window / Input

« on: November 02, 2009, 05:31:16 pm »

I got some code



world.hpp

Code: [Select]


#ifndef WORLD
#define WORLD

#include <iostream>
#include <vector>
#include <SFML/Graphics.hpp>
#include "BaseEnt.hpp"
#include "Cockpit.hpp"

class World
{
private:
sf::Input& Input;
sf::Event Event;
sf::RenderWindow GameWindow;
public:
std::vector<BaseEnt*> Entities;
World();
void Draw();
void Think();
void CreateCockpit();
sf::RenderWindow &GetApp() {return GameWindow;}
};

#endif

world.cpp

Code: [Select]


#include "world.hpp"

World::World()
{
GameWindow.Create(sf::VideoMode(800,600,32),"Space Snapper",sf::Style::Close,sf::WindowSettings(8,24,2));
GameWindow.SetFramerateLimit(100);
Input = GameWindow.GetInput();
std::cout<<"World Created !" << std::endl;
}

Errors :

1>c:\users\quincy\documents\visual studio 2008\projects\space snapper\space snapper\world.cpp(4) : error C2758: 'World::Input' : must be initialized in constructor base/member initializer list
1>        c:\users\quincy\documents\visual studio 2008\projects\space snapper\space snapper\world.hpp(13) : see declaration of 'World::Input'

I know this is something with initializers lists but I still don't know how to fix it.

Graphics / Font help

« on: August 31, 2009, 05:10:40 pm »

Did you define SFML_DYNAMIC?

Uhmmm, No ?

Also I calculated the fps and rounded it, how would I convert+add it to the string.

Graphics / Font help

« on: August 31, 2009, 04:55:28 pm »

Im trying to create my own font, but since I added the font part it gives me this error :

1>sfml.obj : error LNK2001: unresolved external symbol "private: static unsigned int * sf::Font::ourDefaultCharset" (?ourDefaultCharset@Font@sf@@0PAIA)

Code

Code: [Select]


#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>  
#include <iostream>
 
class Debug    
{    
private:    
    sf::RenderWindow& Render;  
    sf::String Text;  
    sf::Font IDK;

public:    
    Debug(sf::RenderWindow& app);    
    void Draw();  
};  
   
Debug::Debug(sf::RenderWindow& app) : Render(app)  
{  
if (!IDK.LoadFromFile("arial.ttf"))
{
std::cout<<"Cannot load font !";
}

    Text.SetText("FPS :");    
    Text.SetFont(sf::Font::GetDefaultFont());    
    Text.SetSize(10);    
    Text.SetPosition(5.f, 5.f);  
Text.SetColor(sf::Color(0,0,0,255));
}    
   
void Debug::Draw()  
{  
    Render.Draw(Text);    
}


This code is called by a sfml.cpp

the IDK part is cause I thought it may had to do something with the name.
