Computes the dot product of one vector with another or itself.
vector:Dot(other) vector:GetLengthSquared()
Arguments[]
- other
- table - A Vector2DMixin or Vector3DMixin (must be the same kind as the original vector).
Details[]
- GetLengthSquared() is equivalent to
vector:Dot(vector), resulting in the sum of the squares of its coordinates.
Example[]
local vector = CreateVector2D(3, 4)
print vector:GetLengthSquared() -- 25
Patch changes[]
Patch 7.2.0 (2017-03-28): Added.[1][2]
