Point2 Values

Values and Collections - Quick Navigation

The point2 class defines the characteristics of points in 2D space.

This class is a 2D version of Point3 and is used in utility rollout positioning parameters and for accessing Bitmap values, etc.

See also 2D and 3D Point Literals.

Literals

[<expr>, <expr>] 

[x, y]
[10, 20]
[sin x, cos x]

Constructors

point2 <x> <y>-- x and y are numbers 
<point3> as point2-- created from the x and y components of the point3 

Properties

<point2>.x: Float 
<point2>.y: Float 

Operators

<point2> == <point2> 
<point2> != <point2>   
<point2> + <point2_or_number> 
<point2> - <point2_or_number> 
<point2> * <point2_or_number> 
<point2> / <point2_or_number> 

Standard vector arithmetic. If the second operand is a number it does scalar arithmetic on vector.

-<point2> 

unary minus

<point2>[<integer>]

Returns a component of the Point2 as a float. Valid range on the index is 1 to 2.

<point2>[<integer>]=<float> 

Sets a component of the Point2 to the float. Valid range on the index is 1 to 2.

Methods

copy <point2> 

Creates a new copy of the point2 value.

newPoint = copy oldPoint

The new value contains a copy of the input point2 value, and is independent of the input point2 value.

random <point2> <point2> 

Generates a pseudo-random point between the given points.

length<point2>

Returns the length of the vector.

distance <point2> <point2> 

Returns the distance between the points - length of (point 2 - point 1).

normalize <point2> 

Returns the point2 value normalized such that the vector length equals 1.
