Vector (Function)

Function to create 3D vector / coordinate. Receives either three arguments (x,y,z), two (x,y; z=0), or one (x=y=z). Can also convert array / list of numbers (V([1,2,3]) becomes V(1,2,3)).

Types:

• Draw: Draw

Static Fields:

• zero: Vector - Vector(0, 0, 0).
• one: Vector - Vector(1, 1, 1).
• forward: Vector - Vector(0, 0, 1).
• fwd: Vector - Alias to forward - Vector(0, 0, 1).
• back: Vector - Vector(0, 0, -1).
• up: Vector - Vector(0, 1, 0).
• down: Vector - Vector(0, -1, 0).
• left: Vector - Vector(-1, 0, 0).
• right: Vector - Vector(1, 0, 0).
• none: Vector - Vector(nan, nan, nan).

Static Methods:

• cross(): Vector, a Vector, b Vector
  • Cross product.
• crs(): Vector, a Vector, b Vector
  • Cross product. (Alias to cross)
• scale(): Vector, a Vector, b Vector
  • Scale vector by vector. Per axis. Multiplication does the same.
• shrink(): Vector, a Vector, b Vector
  • Shrink vector by vector. Per axis. Division does the same.
• abs(): Vector, v Vector
  • Vector with coordinates changed to non-negative.
• dot(): double, a Vector, b Vector
  • Dot product.
• angle(): double, a Vector, b Vector
  • Angle between vectors (0..180).

Vector (Instance)

3D vector / coordinate. All the usual operators were implemented, multiplication and division can use both vector (per-axis) and number (all-axes). Beware that multiplication is scaling, not cross product or dot - use appropriate function for these.

Instance Properties:

• native: Vector3d - Native KSP Vector3d (double x, y, z).
• x: double - The X-coordinate
• y: double - The Y-coordinate
• z: double - The Z-coordinate
• size: double - Size of the vector - sqrt(x*x+y*y+z*z). Scale if setting.
• magnitude: double - Alias to size of the vector - sqrt(x*x+y*y+z*z). Scale if setting.
• squareSize: double - Square size of the vector - x*x+y*y+z*z. Scale if setting.
• normalized: Vector - Get normalized vector (size 1).
• Vector3: Vector3 - UnityEngine.Vector3 (float x,y,z).
• Vector2: Vector2 - UnityEngine.Vector2 (float x,y).

Instance Methods:

• dot(): double, rhs Vector
  • Dot product of this vector and another vector.
• angle(): double, rhs Vector
  • Angle between this vector and another vector (0..180).
• angle(): double, rhs Vector, axis Vector
  • Angle between this vector and another vector given point above the plane (-180..180). Note that the vectors are not projected onto the plane, the angle of cross product of the two and the third vector being above 90 makes the result negative.
• cross(): Vector, rhs Vector
  • Cross product of this vector with another vector. Note that Unity uses left-handed coordinate system, so ship.away.cross(ship.velocity) points down (towards south pole) in prograde-orbit (which is the usual).
• projectOnVector(): Vector, normal Vector
  • Project this vector onto another vector.
• projectOnPlane(): Vector, normal Vector
  • Project this vector onto plane specified by normal vector.
• project(): Vector, normal Vector
  • Project this vector onto another vector (alias to projectOnVector).
• exclude(): Vector, normal Vector
  • Project this vector onto plane specified by normal vector (alias to projectOnPlane).
• rotate(): Vector, angle double, axis Vector
  • Rotate vector by an angle around axis.
