Detect Last Drawn Shape - c++

Question

I'm creating a game in C++ using SFML but I ran into an issue with moving shapes using the mouse.
I am drawing multiple shapes, each shape has it's own handle input method and when I handle the window event, I loop over a vector array and call the handle input method of each shape.
void Plank::HandleInput(sf::Event event)
{
switch (event.type)
{
case sf::Event::MouseButtonPressed:
{
if (event.mouseButton.button == sf::Mouse::Button::Left)
{
m_MouseHold = true;
std::cout << "Left Press\n";
}
if (m_Shape.getGlobalBounds().contains(sf::Vector2f(sf::Mouse::getPosition(m_Game->m_Window))))
{
std::cout << "In Bounds\n";
m_MoveShape = true;
}
break;
}
case sf::Event::MouseButtonReleased:
{
m_MouseHold = false;
m_MoveShape = false;
break;
}
case sf::Event::MouseMoved:
{
if (m_MoveShape)
{
std::cout << "Move Shape\n";
m_Shape.setPosition(sf::Vector2f(sf::Mouse::getPosition(m_Game->m_Window)));
}
break;
}
default: break;
}
}
The issue is that if two shapes overlap and you click on where the shapes intersect you can move both shapes.
I want to only be able to move the shape which is on top, but I couldn't figure out how after some thinking and research.

Answer 1

So I did something similar to what you said #0x5453
In my window poll event I looped over my array of shapes and stored the array position of the shape which contained my mouse in its global bounds first. Then from there on I simply moved the shape in the array position I had noted.
for (size_t i = m_PlankObjects.size(); i-- > 0;)
{
if (m_PlankObjects[i].m_Shape.getGlobalBounds().contains(sf::Vector2f(sf::Mouse::getPosition(m_Game->m_Window))))
{
selectedObject = i;
break;
}
}
