Vector3i

A 3D vector using integer coordinates.

描述

A 3-element structure that can be used to represent 3D grid coordinates or any other triplet of integers.

It uses integer coordinates and is therefore preferable to Vector3 when exact precision is required. Note that the values are limited to 32 bits, and unlike Vector3 this cannot be configured with an engine build option. Use int or PackedInt64Array if 64-bit values are needed.

Note: In a boolean context, a Vector3i will evaluate to false if it's equal to Vector3i(0, 0, 0). Otherwise, a Vector3i will always evaluate to true.

Property Descriptions

int x = 0

The vector's X component. Also accessible by using the index position [0].


int y = 0

The vector's Y component. Also accessible by using the index position [1].


int z = 0

The vector's Z component. Also accessible by using the index position [2].


Constructor Descriptions

Vector3i Vector3i ( )

Constructs a default-initialized Vector3i with all components set to 0.


Vector3i Vector3i ( Vector3i from )

Constructs a Vector3i as a copy of the given Vector3i.


Vector3i Vector3i ( Vector3 from )

Constructs a new Vector3i from the given Vector3 by truncating components' fractional parts (rounding towards zero). For a different behavior consider passing the result of Vector3.ceil, Vector3.floor or Vector3.round to this constructor instead.


Vector3i Vector3i ( int x, int y, int z )

Returns a Vector3i with the given components.


Method Descriptions

Vector3i abs ( ) const

Returns a new vector with all components in absolute values (i.e. positive).


Vector3i clamp ( Vector3i min, Vector3i max ) const

Returns a new vector with all components clamped between the components of min and max, by running @GlobalScope.clamp on each component.


float length ( ) const

Returns the length (magnitude) of this vector.


int length_squared ( ) const

Returns the squared length (squared magnitude) of this vector.

This method runs faster than length, so prefer it if you need to compare vectors or need the squared distance for some formula.


int max_axis_index ( ) const

Returns the axis of the vector's highest value. See AXIS_* constants. If all components are equal, this method returns AXIS_X.


int min_axis_index ( ) const

Returns the axis of the vector's lowest value. See AXIS_* constants. If all components are equal, this method returns AXIS_Z.


Vector3i sign ( ) const

Returns a new vector with each component set to 1 if it's positive, -1 if it's negative, and 0 if it's zero. The result is identical to calling @GlobalScope.sign on each component.


Vector3i snapped ( Vector3i step ) const

Returns a new vector with each component snapped to the closest multiple of the corresponding component in step.


Operator Descriptions

bool operator != ( Vector3i right )

Returns true if the vectors are not equal.


Vector3i operator % ( Vector3i right )

Gets the remainder of each component of the Vector3i with the components of the given Vector3i. This operation uses truncated division, which is often not desired as it does not work well with negative numbers. Consider using @GlobalScope.posmod instead if you want to handle negative numbers.

print(Vector3i(10, -20, 30) % Vector3i(7, 8, 9)) # Prints "(3, -4, 3)"

Vector3i operator % ( int right )

Gets the remainder of each component of the Vector3i with the given int. This operation uses truncated division, which is often not desired as it does not work well with negative numbers. Consider using @GlobalScope.posmod instead if you want to handle negative numbers.

print(Vector3i(10, -20, 30) % 7) # Prints "(3, -6, 2)"

Vector3i operator * ( Vector3i right )

Multiplies each component of the Vector3i by the components of the given Vector3i.

print(Vector3i(10, 20, 30) * Vector3i(3, 4, 5)) # Prints "(30, 80, 150)"

Vector3 operator * ( float right )

Multiplies each component of the Vector3i by the given float. Returns a Vector3.

print(Vector3i(10, 15, 20) * 0.9) # Prints "(9, 13.5, 18)"

Vector3i operator * ( int right )

Multiplies each component of the Vector3i by the given int.


Vector3i operator + ( Vector3i right )

Adds each component of the Vector3i by the components of the given Vector3i.

print(Vector3i(10, 20, 30) + Vector3i(3, 4, 5)) # Prints "(13, 24, 35)"

Vector3i operator - ( Vector3i right )

Subtracts each component of the Vector3i by the components of the given Vector3i.

print(Vector3i(10, 20, 30) - Vector3i(3, 4, 5)) # Prints "(7, 16, 25)"

Vector3i operator / ( Vector3i right )

Divides each component of the Vector3i by the components of the given Vector3i.

print(Vector3i(10, 20, 30) / Vector3i(2, 5, 3)) # Prints "(5, 4, 10)"

Vector3 operator / ( float right )

Divides each component of the Vector3i by the given float. Returns a Vector3.

print(Vector3i(10, 20, 30) / 2.9) # Prints "(5, 10, 15)"

Vector3i operator / ( int right )

Divides each component of the Vector3i by the given int.


bool operator < ( Vector3i right )

Compares two Vector3i vectors by first checking if the X value of the left vector is less than the X value of the right vector. If the X values are exactly equal, then it repeats this check with the Y values of the two vectors, and then with the Z values. This operator is useful for sorting vectors.


bool operator <= ( Vector3i right )

Compares two Vector3i vectors by first checking if the X value of the left vector is less than or equal to the X value of the right vector. If the X values are exactly equal, then it repeats this check with the Y values of the two vectors, and then with the Z values. This operator is useful for sorting vectors.


bool operator == ( Vector3i right )

Returns true if the vectors are equal.


bool operator > ( Vector3i right )

Compares two Vector3i vectors by first checking if the X value of the left vector is greater than the X value of the right vector. If the X values are exactly equal, then it repeats this check with the Y values of the two vectors, and then with the Z values. This operator is useful for sorting vectors.


bool operator >= ( Vector3i right )

Compares two Vector3i vectors by first checking if the X value of the left vector is greater than or equal to the X value of the right vector. If the X values are exactly equal, then it repeats this check with the Y values of the two vectors, and then with the Z values. This operator is useful for sorting vectors.


int operator [] ( int index )

Access vector components using their index. v[0] is equivalent to v.x, v[1] is equivalent to v.y, and v[2] is equivalent to v.z.


Vector3i operator unary+ ( )

Returns the same value as if the + was not there. Unary + does nothing, but sometimes it can make your code more readable.


Vector3i operator unary- ( )

Returns the negative value of the Vector3i. This is the same as writing Vector3i(-v.x, -v.y, -v.z). This operation flips the direction of the vector while keeping the same magnitude.
