know if an shape is completly inside of an other

[EIRBLAST]

Hello everyone,

I tried to made a way to know if an rectangle shape is completly inside of an other rectangle shape
this is all i can come up with:

bool Map::Limit(const sf::RectangleShape body)
{
    sf::RectangleShape MapBody;
    MapBody.setPosition(MapStartPos.x,MapStartPos.y);
    MapBody.setSize(sf::Vector2f(MapStartPos.x+MapSize.x*TileSize.x,MapStartPos.y+MapSize.y*TileSize.y));

    if(MapBody.getGlobalBounds().intersects(body.getGlobalBounds()))
    {
        return true;
    }
    else
    {
        return false;
    }
}
 

obviously this only work when the "body" is completly outside of the map
Can someone help me please ? thanks !

A simple solution is to check that all for corners of the rect are contained within the other rect (rect.contains()).

I think of that !
But i don't know how to pull it out :/

what do i have to modify it ? should i do it like this ?

    if(MapBody.getGlobalBounds().intersects(sf::Rect.contains(/*What do i put here ?*/))
    {
        return true;
    }
    else
    {
        return false;
 

Because this return a boolean to an other bool, i don't think this a thing x).

First, get the points of each of the four corners of the "inner" rectangle. You will then have four sf::Vectors containing those corner positions.
Then, test to see if those positions are contained within the "outer" rectangle.
If, and only if, all four corner positions are contained within the "outer" rectangle is that "inner" rectangle fully inside the "outer" rectangle.
