IntRect Struct Reference

Integer Rectangle. More...

Detailed Description

Constructor & Destructor Documentation

IntRect ( int  xmin,
int  ymin,
int  xmax,
int  ymax 
)

Member Function Documentation

bool Contains ( int  x,
int  y 
)
void DebugDraw ( GraphTransform  transform,
Color  color 
)

Draws some debug lines representing the rect.

override bool Equals ( System.Object  obj)
IntRect Expand ( int  range)

Returns a new rect which is expanded by range in all directions.

Parameters
rangeHow far to expand. Negative values are permitted.
IntRect ExpandToContain ( int  x,
int  y 
)

Returns a new IntRect which is expanded to contain the point.

override int GetHashCode ( )
static IntRect Intersection ( IntRect  a,
IntRect  b 
)
static

Returns the intersection rect between the two rects.

The intersection rect is the area which is inside both rects. If the rects do not have an intersection, an invalid rect is returned.

See Also
IsValid
static bool Intersects ( IntRect  a,
IntRect  b 
)
static

Returns if the two rectangles intersect each other.

bool IsValid ( )

Returns if this rectangle is valid.

An invalid rect could have e.g xmin > xmax. Rectamgles with a zero area area invalid.

IntRect Offset ( Int2  offset)

Returns a new rect which is offset by the specified amount.

IntRect Offset ( int  x,
int  y 
)

Returns a new rect which is offset by the specified amount.

static bool operator!= ( IntRect  a,
IntRect  b 
)
static
static bool operator== ( IntRect  a,
IntRect  b 
)
static
IntRect Rotate ( int  r)

Returns a new rect rotated around the origin 90*r degrees.

Ensures that a valid rect is returned.

override string ToString ( )
static IntRect Union ( IntRect  a,
IntRect  b 
)
static

Returns a new rect which contains both input rects.

This rectangle may contain areas outside both input rects as well in some cases.

Matrices for rotation.

Each group of 4 elements is a 2x2 matrix. The XZ position is multiplied by this. So

//A rotation by 90 degrees clockwise, second matrix in the array
(5,2) * ((0, 1), (-1, 0)) = (2,-5)

int xmin
int ymax
