Methods
- Vec3:AsSpringVector ()
-
Returns vector in the form that Spring expects.
Returns:
-
{number}
List of X, Y, Z coordinates
- Vec3:Cross (vector)
-
Computes the cross product with another vector.
Parameters:
- vector Vec3 The other vector.
Returns:
-
Vec3
The cross product.
- Vec3:Distance (vector)
-
Computes the distance between two vectors.
Parameters:
- vector Vec3 The other vector.
- Vec3:DotProduct (vector)
-
Computes a dot product with another vector.
Parameters:
- vector Vec3 The other vector.
- Vec3:Length ()
- Computes the length of the vector.
- Vec3:LengthSqr ()
- Computes the square length of the vector.
- Vec3:Mul (n)
-
Multiplies the vector by the given number in-place.
Parameters:
- n
Returns:
self - Vec3:Normalize ()
-
Normalizes the vector in-place.
Returns:
self - Vec3:Rotate2D (angle)
-
Rotates vector around Y axis by given angle in degrees in-place.
A mathematically correct variant = negative angle values implies clockwise rotation.
Parameters:
- angle number Angle in X-Z plane.
Returns:
self - Vec3:ToHeading ()
-
Convert vector in 2D heading in degrees between 0-360
Returns:
-
number
Angle in X-Z plane.
- Vec3:Zero ()
-
Sets the current instance to zeros.
Returns:
self
