Hello,
i need help to solve this problem..
My problem is the fact that my mouse intersects with a rotated rectangleshape as if it would be a non-rotated square
so my question is how to cut this off ( for my collision detection )?

I'm pretty sure SFML supports this:
rect.
getGlobalBounds
(
)
.
contains
(
mousePos
)
;

Nothing to add to Geheim's post. The algorithm is pretty basic and can be found easily with Google.

SFML doesn't support rotated rectangles. The global bounds of a rotated entity is the axis-aligned bounding box of the entity's bouding box -- the outer rect in cobrapitz's drawing.

Ah, right. It should work for sprites though.

Not if they are rotated.
