Bounding Box Help :/

[oOhttpOo]

Hello, I'm trying to make a simple game that needs to detect when one sprite touches another's bounding box, but I don't quite understand the code for this. Sorry if this has already been posted, but I could not find any help. The bit I don't understand is

// check collision with another box (like the bounding box of another entity)
sf::FloatRect otherBox = ...; //What goes here??
if (boundingBox.intersects(otherBox))
{
//collision
}

The sprite has an getGlobalBounds() function which returns a FloatRect.

Keep in mind it's the full bounding box of the sprite object, even if the entire sides of the sprite are empty or transparent.

I did that, but it seems to intersect all the time when it is no where near the sprite. I have this code:

sf::FloatRect helib = heli.getGlobalBounds();
sf::FloatRect obs1b = obs1.getGlobalBounds();
...
if (helb.intersects(obs1b))
                {
                        window.close();
                }

Use your debugger. Set a breakpoint and inspect the values of the rectangles you are comparing for intersection.

hmm... This doesn't make any sense as far as I can see. Even when the two sprites are no where near each other, it still thinks the bounding boxes collide  And also they collide even when one isn't even drawn.

Removing the draw call for a sprite isn't gonna stop its logic from being ran. It still exists, even if you can't visually see it.

Nevermind I fixed it. In case anyone else had this issue, I forgot to put the .getGlobalBounds in the same loop.
