Function vector:normalize
Returns a normalized representation of the vector.
Syntax	vector:normalize()
Returns	float
Part of	ComputerCraft
API	vector

Example
Normalizes a vector and prints the resulting vector. Also prints the length to show it does equal 1.
Code	local a = vector.new(1, 2, 3) local c = a:normalize() print(c.x) print(c.y) print(c.z) print(c:length()) --0.26726124 --0.5345225 --0.80178374 --1

Example
Code to recreate the function. Gives insight into what the function does.
Code	local a = vector.new(1, 2, 3) local len = a:length() local c = vector.new(a.x / len, a.y / len, a.z / len) --c.x = 0.26726124 --c.y = 0.5345225 --c.z = 0.80178374
