const float FloatPrecision = 1000F

Precision as a float

const int Precision = 1000

Precision for the integer coordinates.

One world unit is divided into [value] pieces. A value of 1000 would mean millimeter precision, a value of 1 would mean meter precision (assuming 1 world unit = 1 meter). This value affects the maximum coordinates for nodes as well as how large the cost values are for moving between two nodes. A higher value means that you also have to set all penalty values to a higher value to compensate since the normal cost of moving will be higher.

const float PrecisionFactor = 0.001F

1 divided by Precision

Property Documentation

int costMagnitude
get

Magnitude used for the cost between two nodes.

The default cost between two nodes can be calculated like this:

int cost = (node1.position-node2.position).costMagnitude;

This is simply the magnitude, rounded to the nearest integer

float magnitude
get

Returns the magnitude of the vector.

The magnitude is the 'length' of the vector from 0,0,0 to this point. Can be used for distance calculations:

Debug.Log ("Distance between 3,4,5 and 6,7,8 is: "+(new Int3(3,4,5) - new Int3(6,7,8)).magnitude);
float sqrMagnitude
get

The squared magnitude of the vector.

long sqrMagnitudeLong
get

The squared magnitude of the vector.

int this[int i]
getset
int unsafeSqrMagnitude
get
Warning
Can cause number overflows if the magnitude is too large
float worldMagnitude
get

The magnitude in world units.
