Title: Get position of entity local to a window/view
Post by: Gauzr on June 12, 2015, 06:48:32 pm

Hi, I would like to get simply the y coord of a shape, but when I try do this it only gets the y distance from it's origin. I don't want this. I want to get the y coord of the whole 600x600 window (with 0, 0 at top left) but using setOrigin. Sorry if my English was a bit bad.

shape.setOrigin(-50, -400);
...


int shapepos_y = shape.getPosition().y ; // when the shape moves up 50 for example, it only returns -50, but I need it -350

std::cout<<"shapepos_y =" << shapepos_y;

getPosition() provides the position of the origin.

I suggest you read the official tutorials (again), because setting the origin to negative value is very rarely what you actually want to do. To set he shape's position use setPosition().

I am curious as to what you intended to achieve with this:

shape.setOrigin(-50, -400);

Ah, now I think I could of just setPosition(positive cords) done instead... This was the solution to this, thanks for the info.
