Vector3

Vector3 Functions

Vector3 is a basic math type that is made up of 3 real numbers typically used to represent positions, velocities, and directions. As of 0.65, Vector3 objects in scripting have gotten a significant optimization to eliminate their previous need to allocate memory that would then need garbage collected. As a result, scripts that use them heavily, especially in mathematical operations, should not trigger garbage collection cycles, and should also run a bit faster.

Vector3 Methods

Concave

b = v.Concave(v1,v2);

CrossProduct

v2 = v.CrossProduct(v1); // result is perpendicular to v and v1

Distance

f = v.Distance(v1);

Distance2

f = v.Distance2(v1); // squared distance

DistanceXY

f = v.DistanceXY(v1); // squared 2D distance

DotProduct

f = v.DotProduct(v1); // v.x * v1.x + v.y * v1.y + v.z * v1.z

GetPitch

f = v.GetPitch(); // asin(v.z)

GetYaw

f = v.GetYaw(); // -atan2(-v.x, v.y)

IsZero

b = v.IsZero();

Length

f = v.Length();

Length2

f = v.Length2(); // squared length

Normalize

v2 = v.Normalize();

Reflection

v2 = v.Reflection(v1);

Set, SetXYZ

v2 = v.Set(x,y,z);
