Easy method to check if a point is inside of a Rectangle shape
« on: February 08, 2020, 09:18:36 am »
i want to check for collision detection of rectangle but didn't find a way to check if the point is inside the rectangle so any ideas?

sf::Rect<T>::contains()

Also you probably can find a few hundred responses by googling "rectangle point collision detection sfml" ;)

Isn't that for rectangle whose sides are aligned with axes?

I meant to ask if it had rotations and other transformations applied ?

Then you can apply the inverse transform of the rectangle to the point, so you're back into a coordinate system where the rectangle is aligned with axes.

Or you can use one of the algorithms which works with any convex shape (Google them).
