Points and Rectangles
put (150,47) into pointA
put "250,98" into pointB
A rectangle can be represented by any list of two points, by a list of four numbers or by a text string consisting of four numbers separated by commas (representing two points). The two points indicate two opposite corners of the rectangle (either the topleft and bottomright corners, or the bottomleft and topright corners, listed in either order).
put (pointA,pointB) into myRect
put "15,28,19,72" into bounds
The is within operator can be used to test whether a point lies within a rectangle or one rectangle is completely within another (see the full description in Expressions):
if (18,35) is within bounds then scoreHit
x, y, width, height, origin, and size functions
What it Does
These functions can be used to extract the various component values of a point or rectangle. The functions x() and y() can be used with points and rectangles to obtain the x and y coordinates of the point, or of the origin point of the rectangle. The origin() and size() functions can be used with rectangles to obtain the origin point (the minimum x and y values) and the size (a list of two numbers representing the width and height, respectively) of the rectangle. The width() and height() functions can be used with rectangles or sizes to obtain the width or height.
Examples
These functions are most commonly used with the dot (.), apostropheS (‘s) or “of” syntax, similar to accessing a property of an object, but keep in mind that these functions return readonly values only:
put pointA.x into horizontalLocation
put the y of pointA into verticalLocation
put myRect's origin into topLeftCorner
put the size of bounds into outerRect
put height of imageRect into verticalSpaceNeeded

Syntax:

top, bottom, left, right, topLeft, topRight, bottomLeft, bottomRight, center, topCenter, bottomCenter, leftCenter, and rightCenter functions
What it Does
These functions can be used to find the coordinates of various parts of a rectangle.
The top(), bottom(), left() and right() functions return a single number which is the y coordinate of the top or bottom edge, or the x coordinate of the left or right edge, respectively, of a rectangle.
The topLeft(), topRight(), bottomLeft() and bottomRight() functions return the coordinates of the point at the indicated corner of a rectangle.
The center() function returns the coordinates of the center of a rectangle, and the topCenter(), bottomCenter(), leftCenter() and rightCenter() functions return the coordinates of the point at the center of the indicated edge of a rectangle.
Examples
These functions are most commonly used with the dot (.), apostropheS (‘s) or “of” syntax, similar to accessing a property of an object, but keep in mind that these are not properties, but functions which return readonly values:
put boundingBox.top into highestEdge
put the bottomRight of doorFrame into anchorPoint
put myRect's center into centerPoint
put the leftCenter of bounds into alignmentPoint
