Instance Method Details

#*(n) ⇒ Object

Returns a new FXVec2d instance obtained by memberwise multiplication of this vector's elements by the scalar n.



46
 
# File 'rdoc-sources/FXVec2d.rb', line 46

def *(n); end

#+(other) ⇒ Object

Returns a new FXVec2d instance obtained by memberwise addition of the other FXVec2d instance with this one.



32
 
# File 'rdoc-sources/FXVec2d.rb', line 32

def +(other); end

#-(other) ⇒ Object

Returns a new FXVec2d instance obtained by memberwise subtraction of the other FXVec2d instance from this one.



39
 
# File 'rdoc-sources/FXVec2d.rb', line 39

def -(other); end

#-@ ⇒ Object

Returns a new FXVec2d instance which is the negation of this one.



25
 
# File 'rdoc-sources/FXVec2d.rb', line 25

def -@(); end

#/(n) ⇒ Object

Returns a new FXVec2d instance obtained by memberwise division of this vector's elements by the scalar n. Raises ZeroDivisionError if n is identically zero.



54
 
# File 'rdoc-sources/FXVec2d.rb', line 54

def /(n); end

#==(other) ⇒ Object

Return true if this vector is equal to other.



62
 
# File 'rdoc-sources/FXVec2d.rb', line 62

def ==(other); end

#[](index) ⇒ Object

Returns the element at index, where index is 0 or 1. Raises IndexError if index is out of range.



16
 
# File 'rdoc-sources/FXVec2d.rb', line 16

def [](index); end

#[]=(index, value) ⇒ Object

Set the element at index to value and return value. Raises IndexError if index is out of range.



22
 
# File 'rdoc-sources/FXVec2d.rb', line 22

def []=(index, value); end

#clamp(lo, hi) ⇒ Object

Clamp the values of this vector between limits lo and hi.



75
 
# File 'rdoc-sources/FXVec2d.rb', line 75

def clamp(lo, hi); end

#dot(other) ⇒ Object

Returns the dot (scalar) product of this vector and other.



59
 
# File 'rdoc-sources/FXVec2d.rb', line 59

def dot(other); end

#hi(other) ⇒ Object

Return a new FXVec2d instance which is the greater of this vector and other.



93
 
# File 'rdoc-sources/FXVec2d.rb', line 93

def hi(other); end

#inspect ⇒ Object 



241
 
# File 'lib/fox16/core.rb', line 241

def inspect; to_a.inspect; end

#length ⇒ Object

Return the length (magnitude) of this vector.



72
 
# File 'rdoc-sources/FXVec2d.rb', line 72

def length; end

#length2 ⇒ Object

Return the square of the length of this vector.



67
 
# File 'rdoc-sources/FXVec2d.rb', line 67

def length2; end

#lo(other) ⇒ Object

Return a new FXVec2d instance which is the lesser of this vector and other.



87
 
# File 'rdoc-sources/FXVec2d.rb', line 87

def lo(other); end

#normalize ⇒ Object

Return a new FXVec2d instance which is a normalized version of this one.



81
 
# File 'rdoc-sources/FXVec2d.rb', line 81

def normalize; end

#to_a ⇒ Object

Convert to array
