[Solved]Doubt in using getPosition()
« on: August 15, 2013, 05:48:08 pm »
Hello

Whenever we use getPosition() in a sf::RectangleShape object, what coordinates are returned?

For example, suppose we have the following rectangle, called sf::RectangleShape Rect1 and we call Rect1.getPosition(), what is returned?



Thanks

Documentation, about Origin :

Quote
The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

So in the above case Rect1.getPosition() returns 125, 130?

Thanks for the help

No.. it returns (100,100) as lo-x explained.. The top-left corner! :))

This is only the right answer if the origin is (0,0) as the default goes, though. As Lo-X also quoted :D

The default origin is (0, 0) so the upper left corner of the rectangle.  you can change the origin with setOrigin()
