XNA矩形和包含，将变得疯狂

Question

I'm going to be crazy. In fact, i use Rectangle to know if a point if inside of a rectangle.

My rectangle is define like this : {X:0 Y:480 Width:480 Height:480} The point (Vector2) is define like this : {X:283,3333 Y:141,1111}

Normaly, the point is inside of the rectangle ? But not...

if (rectangle.Contains(new Point((int)point.X, (int)point.Y)))
{
   return true;
}
return false;

With another test, it work with the same code : {X:-480 Y:0 Width:480 Height:480} contain {X:-12,22222 Y:12,22223}

Plz, i really need some advices.

Seriously, i don't understand why it don't works !

Answer 1

如果矩形的起始点为Y = 480，则点（283，141）不在其中。

Answer 2

Sorry but how is the point inside the rectangle?

A simple test to know if a point is inside a rectangle:

if ( p.X >= rectangle.X && p.X <= Rectangle.X + Rectangle.Width && p.X >= rectangle.X && p.Y <= Rectangle.Y + Rectangle.Height)

The Point (283, 141) obviously fail the third condition and therefor is not in the Rectangle.

It is however in this rectangle {X:0 Y:0 Width:480 Height:480}
