Instance Attribute Details

#x ⇒ Float

The x value of the point.

Returns:

32
 
# File 'gems/carbuncle-math/mrblib/point.rb', line 30

def inspect
  "Point(#{x}, #{y})"
end

#xy ⇒ Carbuncle::Point

A vectorial operation to extract [x, y] from the point or to assign it

Returns:

# File 'gems/carbuncle-math/mrblib/point.rb', line 30

def inspect
  "Point(#{x}, #{y})"
end

#y ⇒ Float

The y value of the point.

Returns:

# File 'gems/carbuncle-math/mrblib/point.rb', line 30

def inspect
  "Point(#{x}, #{y})"
end

#yx ⇒ Carbuncle::Point

A vectorial operation to extract [y, x] from the point or to assign it

Examples:

vectorial operations

# swap a value with another:
point.xy = point.yx # swaps x and y
# the same as:
point.x, point.y = point.y, point.x

Returns:
