I'm trying to load images and return them so then my class can load the images. But I'm complete confused how it works.
This is my function:
[source lang="cpp"]void menuPreload(std::string theme,std::string theme_on,sf::Texture &button, sf::Texture &button_on,int &width,int &height){
std::string img;
std::string img_on;
img = theme;
img_on = theme_on;
if (!button.loadFromFile(img)){
exit(4);
}
if (!button_on.loadFromFile(img_on)){
exit(5);
}
sf::Sprite sprite(button);
width = sprite.getLocalBounds().width;
height = sprite.getLocalBounds().height;
}[/source]
I think call it like this in my main function:
[source lang="cpp"] sf::Texture button;
sf::Texture button_on;
int width;
int height;
menuPreload(config["Button"],config["Button_On"],button,button_on,width,height); [/source]
After i have preloaded the images i call my class to load the button like this:
[source long="cpp"]
//before loop
Button btn_quit(window.getSize().y/2, 200,width,height);
//inside my loop
btn_quit.RenderBttn(window,mouseX,mouseY,button,button_on);
[/source]
So far i think this is correct... but then in my class i have:
[source lang="cpp"]class Button
{
private:
int m_x, m_y;
int m_w, m_h;
public:
Button(int x, int y, int m_w, int m_h)
{
m_y = y;
m_x = x - m_w/2;
}
bool IsIn( int mouseX, int mouseY )
{
exit(m_h);
if (((mouseX > m_x) && (mouseX < m_x + m_w))
&& ((mouseY > m_y) && (mouseY < m_y + m_h ) ) ) {
return true;
} else {
return false;
}
}
void RenderBttn(sf::RenderWindow &destination,int mouseX, int mouseY,sf::Texture button, sf::Texture button_on)
{
sf::Sprite result(IsIn(mouseX,mouseY) ? button_on : button);
result.setPosition( m_x , m_y);
destination.draw(result);
}
};[/source]
The issue is when the mouse is over the button it doesn't change, m_w seems to be not set or incorrect. Am i on the right lines here... my brain is about to explode ...
