a problem about Shape:getBoundingBox( ) in WIKI

[poorenglish]

Hello;
In the wiki the Shape:getBoundingBox( ) description is "x1, y1, x2, y2, x3, y3, x4, y4 = Shape:getBoundingBox( )
Vertexes are returned starting in the top-left in a counterclockwise fashion (top-left, bottom-left, bottom-right, top-right)"
--http://love2d.org/wiki/Shape:getBoundingBox
I found in the "Tutorial:Physics" use this function.--http://love2d.org/wiki/Tutorial:Physics
Actually the "Vertexes are returned starting in the bottom-left in a clockwise fashion(bottom-left,top-left,top-right,bottom-right)
Is this a mistake for the wiki?
Thks

I think the docs are right.

I suspect the this is another of those issues that come from the way LÖVE interprets the "y" coordinate when drawing - opposite as the "natural" (call it whatever you want) way to interpret it.

I'm not saying that LÖVE's way should be corrected, mind you; I'm just saying that its peculiarities must be taken into account. I had this same problem myself.

When I first read "Top" I assumed it meant "higher on the screen". I then learnt that it meant "the maximum <<y>> value", which is the opposite when drawing. This leads to a lot of interesting surprises; clockwise gets transformed in counter-clockwise.

The same goes for "Bottom"; they are kind of misleading words on this context.

I propose changing the documentation so all the "Top" and "Bottom" read "Maximum y" and "Minimum y" instead.

That explains a lot.. now that I think of it that might be the problem.

Yes，I understand it。
It is different understanding about the "bottom" and "top".

Anyone?

Vertexes are returned starting in the top-left in a counterclockwise fashion (top-left, bottom-left, bottom-right, top-right).

That isn't right. When will it be changed?
