Check collision with vector of shapes

[steven_g]

Hi, what I want to do is check for collision of an sf::FloatRect between any other sf::FloatRect stored in a vector. I don't know how one would do this really. I would of thought you could use a for loop but I'm not sure   

std::vector<sf::FloatRect>myFloatRects(100);                     //  100 floatRects of sf::Shape
sf::FloatRect myPosition = myShape.getGlobalBounds();
if (myPosition.intersects(myFloatRects)){                               // if myPosition intersects any of myFloatRects
//do something
}

Take a look at this for beginner collision

hi, when you need to check any kind of container like a vector or an array you need to loop it , for example :

std::vector<sf::FloatRect>myFloatRects(100);                     //  100 floatRects of sf::Shape
sf::FloatRect myPosition = myShape.getGlobalBounds();
for(int i = 0; i = myFloatRects.size();i++)
if (myPosition.intersects(myFloatRects[i])){                               // if myPosition intersects any of myFloatRects
//do something
}
}

Thanks for both responses, I thought the way to do it was with a for loop, I was just a bit disbelieving

You could also just use something like std::find_if with a lambda.
Or if you just need to know if there is a collision but don't care about the colliding element, then there is std::any_of.
