Graphics / Bullets in SFML.
« on: September 11, 2009, 02:39:38 pm »
It's now like this:
Code: [Select]

if (Window.GetInput().IsMouseButtonDown(sf::Mouse::Left))  shotFired = true;

if (shotFired == true)
{
Window.Draw(Bullet.Bullet);
shotFired = false;
}


It still doesn't work.

Graphics / Bullets in SFML.

This is what I currently have:

Projectile.h
Code: [Select]

#ifndef PROJECTILE_H
#define PROJECTILE_H
#include <SFML/Graphics.hpp>


class Projectile
{
public:
sf::Image BulletImage;
static sf::Sprite Bullet;

public:

void SetDirection(sf::Sprite);

void SetSpeed(float);

};

#endif



Projectile.cpp
Code: [Select]

#include "Projectile.h"
#include <SFML/Graphics.hpp>

sf::Sprite Projectile::Bullet;

void Projectile::SetDirection(sf::Sprite Reference)
{
float TargetRotation = Reference.GetRotation();
Bullet.SetRotation(static_cast<float>(fmod(TargetRotation, 360)));
float BulletRotation = Bullet.GetRotation();
if (BulletRotation < 0)
Bullet.SetRotation(BulletRotation + 360.f);
}

void Projectile::SetSpeed(float SpeedMultiplier)
{
BulletImage.LoadFromFile("bullet.png");
Bullet.SetImage(BulletImage);

float BulletX = Bullet.GetPosition().x;
float BulletY = Bullet.GetPosition().y;

Bullet.SetX(BulletX * SpeedMultiplier);
Bullet.SetY(BulletY * SpeedMultiplier);
}


main.cpp
Code: [Select]

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include "Projectile.h"
#define PI 3.1415926535

int WINAPI WinMain(      
    HINSTANCE hInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpCmdLine,
    int nCmdShow
)
{

sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "Zombie Game Alpha");
sf::Image PlayerImage;
sf::Image Background;
Background.LoadFromFile("background.png");
PlayerImage.LoadFromFile("player.png");
sf::Sprite Player(PlayerImage);
sf::Sprite BackgroundS(Background);
sf::Sprite* follow = &Player;
Player.SetPosition(400,300);
Projectile Bullet;

sf::View Camera(sf::Vector2f(400.f, 300.f), sf::Vector2f(400.f, 300.f));  
sf::Vector2f PPos = Player.GetPosition();

sf::Music InGameMusic;
InGameMusic.OpenFromFile("in_game.ogg");


while(Window.IsOpened())
{
sf::Event Event;
while (Window.GetEvent(Event))
{
if (Event.Type == sf::Event::Closed)
Window.Close();
if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
Window.Close();
}

Bullet.SetDirection(Player);
Bullet.SetSpeed(2);

float ElapsedTime = Window.GetFrameTime();
sf::Vector2f MousePos = Window.ConvertCoords(Window.GetInput().GetMouseX(), Window.GetInput().GetMouseY());
Window.Clear();
if (Window.GetInput().IsKeyDown(sf::Key::W))  Player.Move(0, -425 * ElapsedTime);  
        if (Window.GetInput().IsKeyDown(sf::Key::S))  Player.Move(0,  425 * ElapsedTime);  
if (Window.GetInput().IsKeyDown(sf::Key::A))  Player.Move(-425 * ElapsedTime, 0);
if (Window.GetInput().IsKeyDown(sf::Key::D))  Player.Move(425 * ElapsedTime, 0);  
if (Window.GetInput().IsKeyDown(sf::Key::N))  InGameMusic.Play();
if (Window.GetInput().IsKeyDown(sf::Key::M))  InGameMusic.Stop();
if (Window.GetInput().IsMouseButtonDown(sf::Mouse::Left))  Window.Draw(Projectile::Bullet);
Player.SetCenter(Player.GetSize() / 2.f);
Player.SetRotation(((-1* 360 / PI *(atan2(static_cast<double>(Player.GetPosition().y - MousePos.y), static_cast<double>(Player.GetPosition().x - MousePos.x))))/2)+90);


Camera.SetCenter(follow->GetPosition());
Window.SetView(Camera);
Window.Draw(BackgroundS);
Window.Draw(Player);
Window.Display();
InGameMusic.SetLoop(true);
}
}



Now, when I press the left mouse button, nothing works, what should I do?

Oh, and if someone has any suggestions to improve the coding, please say them.

Thanks in advance.

I was using the following code to do it (found the code here, I take no credit for it), but now, after I successfully got the camera to follow the sprite, the code only works when I start the program, if I move the sprite, it's like the center is out of position, re-setting the center didn't work.

Code: [Select]

#include <SFML/Graphics.hpp>
#define PI 3.1415926535

int WINAPI WinMain(      
    HINSTANCE hInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpCmdLine,
    int nCmdShow
)
{

sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "Zombie Game Alpha");

sf::Image PlayerImage;
sf::Image Background;
Background.LoadFromFile("background.png");
PlayerImage.LoadFromFile("player.png");
sf::Sprite Player(PlayerImage);
sf::Sprite BackgroundS(Background);
sf::Sprite* follow = &Player;
Player.SetPosition(400,300);

sf::View Camera(sf::Vector2f(400.f, 300.f), sf::Vector2f(400.f, 300.f));  
sf::Vector2f PPos = Player.GetPosition();


while(Window.IsOpened())
{
sf::Event Event;
while (Window.GetEvent(Event))
{
if (Event.Type == sf::Event::Closed)
Window.Close();
if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
Window.Close();
}

float ElapsedTime = Window.GetFrameTime();


if (Window.GetInput().IsKeyDown(sf::Key::W))  Player.Move(0, -425 * ElapsedTime);  
        if (Window.GetInput().IsKeyDown(sf::Key::S))  Player.Move(0,  425 * ElapsedTime);  
if (Window.GetInput().IsKeyDown(sf::Key::A))  Player.Move(-425 * ElapsedTime, 0);
if (Window.GetInput().IsKeyDown(sf::Key::D))  Player.Move(425 * ElapsedTime, 0);  

Player.SetCenter(Player.GetSize() / 2.f);


if (Window.GetInput().GetMouseX() <= Player.GetPosition().x) {
Player.SetRotation(((-1* 360 / PI * (atan2(static_cast<double>(Player.GetPosition().y - Window.GetInput().GetMouseY()), static_cast<double>(Player.GetPosition().x - Window.GetInput().GetMouseX()))))/2)+90);
} else {
Player.SetRotation(((-1* 360 / PI *(atan2(static_cast<double>(Player.GetPosition().y - Window.GetInput().GetMouseY()), static_cast<double>(Player.GetPosition().x - Window.GetInput().GetMouseX()))))/2)+90);
}


Window.Clear();
Camera.SetCenter(follow->GetPosition());
Window.SetView(Camera);
Window.Draw(BackgroundS);
Window.Draw(Player);

Window.Display();
}
}

Graphics / Getting the camera to follow a sprite.
« on: September 06, 2009, 04:21:20 pm »
I fixed it, I needed to have View.SetCenter(follow->GetPosition()) instead of GetCenter. And the Window.Clear() tides up everything, now I just need a bigger background and it'll be working, thanks.

The flickering stopped, but it still doesn't work.

This is what I have so far:

Code: [Select]

#include <SFML/Graphics.hpp>

int WINAPI WinMain(      
    HINSTANCE hInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpCmdLine,
    int nCmdShow
)
{

sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "Zombie Game Alpha");

sf::Image PlayerImage;
sf::Image Background;
Background.LoadFromFile("background.png");
PlayerImage.LoadFromFile("player.png");
sf::Sprite Player(PlayerImage);
sf::Sprite BackgroundS(Background);
sf::Sprite* follow = &Player;
Player.SetPosition(400,300);

sf::View Camera(sf::Vector2f(400.f, 300.f), sf::Vector2f(400.f, 300.f));  
sf::Vector2f PPos = Player.GetPosition();




while(Window.IsOpened())
{
sf::Event Event;
while (Window.GetEvent(Event))
{
if (Event.Type == sf::Event::Closed)
Window.Close();
if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
Window.Close();
}

float ElapsedTime = Window.GetFrameTime();


if (Window.GetInput().IsKeyDown(sf::Key::W))  Player.Move(0, -425 * ElapsedTime);  
        if (Window.GetInput().IsKeyDown(sf::Key::S))  Player.Move(0,  425 * ElapsedTime);  
if (Window.GetInput().IsKeyDown(sf::Key::A))  Player.Move(-425 * ElapsedTime, 0);
if (Window.GetInput().IsKeyDown(sf::Key::D))  Player.Move(425 * ElapsedTime, 0);  
 

Player.SetCenter(Player.GetSize() / 2.f);
if (Window.GetInput().GetMouseX() <= Player.GetPosition().x) {
Player.SetRotation(((-1* 360 / 3.1415926535 * (atan2(static_cast<double>(Player.GetPosition().y - Window.GetInput().GetMouseY()), static_cast<double>(Player.GetPosition().x - Window.GetInput().GetMouseX()))))/2)+90);
} else {
Player.SetRotation(((-1* 360 / 3.1415926535 *(atan2(static_cast<double>(Player.GetPosition().y - Window.GetInput().GetMouseY()), static_cast<double>(Player.GetPosition().x - Window.GetInput().GetMouseX()))))/2)+90);
}

Camera.SetCenter(follow->GetCenter());

Window.Draw(BackgroundS);
Window.Draw(Player);
Window.SetView(Camera);
Window.Display();
}
}


And it doesn't work, the window's contents are flickering a lot.

System / Error Message Box?
« on: September 05, 2009, 11:17:09 pm »
Code: [Select]
void ErrorMsg(std::string error, std::string title)
{
MessageBoxA(NULL, error.c_str(), title.c_str(), MB_ICONERROR | MB_OK);
}

Then where you want to put the error write:

Code: [Select]

ErrorMsg("goddamn error didnt load image blabla", "Error Title");
