Check if sf::RectangleShape contains mouse global bounds?
« on: May 30, 2016, 10:44:37 pm »
Hi,
I want to check if an sf::Shape contains the mouse's global bounds (and if left mouse button is clicked), and created the function below:
bool isRectClicked(sf::RectangleShape &rect, sf::RenderWindow &window) {
        sf::IntRect rect(rect.getPosition().x, rect.getPosition().y, rect.getGlobalBounds().width,  
        rect.getGlobalBounds().height);
        if (rect.contains(sf::Mouse::getPosition(window)) && (sf::Mouse::isButtonPressed(sf::Mouse::Left))) {
                return true;
        }
        return false;
}
 

However it says sf::RectangleShape has no member contains. How would I do this or do I have to do it the longer way by checking if the cursor is within the shape dimensions?

G.

You should avoid calling 2 different variables with the same name.
"sf::RectangleShape &rect" and "sf::IntRect rect"

Why don't you just use rect.getGlobalBounds() directly anyway?

Remember to map the mouse position into the view's co-ordinates.

"Luckily" that returns a Vector2f so you can easily check to see if the rectangle shape's global bounds contains that point.
