Title: RectangleShape in a vector
Post by: er4zox on July 26, 2013, 07:56:32 pm

Hello guys !

I have a vector inside a class:

std::vector<sf::RectangleShape*> pShapes;
sf::RectangleShape * p;

If I add something to the vector I do

p = new sf::RectangleShape;
pShapes.push_back(p);

Now the problem:

virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
        {
                for (int i = 0; i < pShapes.size(); ++i)
        {
                                target.draw(pShapes[i],states);
                }
        }

It gives me this error:

I searched for this problem but didn't find anything.

Thanks for your help!

Put a '*' in front of the 'pShapes' I believe.

You've declared it as a pointer but you're trying to draw it to the screen as if it were a normal variable.

There's absolutely no need to use manual memory management here, especially since you most probably don't even delete the allocated memory and thus leave a memory leak mess behind...
Unlike in Java, the initialization in C++ doesn't require you to call new. Maybe you should go again over the "class" chapter in your C++ book. ;)
