Vector2i¶
A 2D vector using integer coordinates.
Description¶
A 2-element structure that can be used to represent 2D grid coordinates or any other pair of integers.
It uses integer coordinates and is therefore preferable to Vector2 when exact precision is required. Note that the values are limited to 32 bits, and unlike Vector2 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 Vector2i will evaluate to false if it's equal to Vector2i(0, 0). Otherwise, a Vector2i will always evaluate to true.

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

Constructor Descriptions¶
Constructs a default-initialized Vector2i with all components set to 0.
Vector2i Vector2i(from: Vector2i)
Constructs a Vector2i as a copy of the given Vector2i.
Vector2i Vector2i(from: Vector2)
Constructs a new Vector2i from the given Vector2 by truncating components' fractional parts (rounding towards zero). For a different behavior consider passing the result of Vector2.ceil, Vector2.floor or Vector2.round to this constructor instead.
Vector2i Vector2i(x: int, y: int)
Constructs a new Vector2i from the given x and y.
Method Descriptions¶
Returns a new vector with all components in absolute values (i.e. positive).
Returns the aspect ratio of this vector, the ratio of x to y.
Vector2i clamp(min: Vector2i, max: Vector2i) const 🔗
Returns a new vector with all components clamped between the components of min and max, by running @GlobalScope.clamp on each component.

Returns a new vector with all components clamped between min and max, by running @GlobalScope.clamp on each component.
int distance_squared_to(to: Vector2i) const 🔗
Returns the squared distance between this vector and to.
This method runs faster than distance_to, so prefer it if you need to compare vectors or need the squared distance for some formula.
float distance_to(to: Vector2i) const 🔗
Returns the distance between this vector and to.
Returns the length (magnitude) of this vector.
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.
Vector2i max(with: Vector2i) const 🔗
Returns the component-wise maximum of this and with, equivalent to Vector2i(maxi(x, with.x), maxi(y, with.y)).
Returns the axis of the vector's highest value. See AXIS_* constants. If all components are equal, this method returns AXIS_X.
Vector2i maxi(with: int) const 🔗

Vector2i min(with: Vector2i) const 🔗
Returns the component-wise minimum of this and with, equivalent to Vector2i(mini(x, with.x), mini(y, with.y)).
Returns the axis of the vector's lowest value. See AXIS_* constants. If all components are equal, this method returns AXIS_Y.
Vector2i mini(with: int) const 🔗
Returns the component-wise minimum of this and with, equivalent to Vector2i(mini(x, with), mini(y, with)).
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.

Returns a new vector with each component snapped to the closest multiple of the corresponding component in step.
Vector2i snappedi(step: int) const 🔗
Returns a new vector with each component snapped to the closest multiple of step.

bool operator !=(right: Vector2i) 🔗
Returns true if the vectors are not equal.
Vector2i operator %(right: Vector2i) 🔗
Gets the remainder of each component of the Vector2i with the components of the given Vector2i. 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(Vector2i(10, -20) % Vector2i(7, 8)) # Prints "(3, -4)"
Vector2i operator %(right: int) 🔗
Gets the remainder of each component of the Vector2i 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(Vector2i(10, -20) % 7) # Prints "(3, -6)"
Vector2i operator *(right: Vector2i) 🔗
Multiplies each component of the Vector2i by the components of the given Vector2i.
print(Vector2i(10, 20) * Vector2i(3, 4)) # Prints "(30, 80)"
Vector2 operator *(right: float) 🔗
Multiplies each component of the Vector2i by the given float. Returns a Vector2.
print(Vector2i(10, 15) * 0.9) # Prints "(9, 13.5)"
Vector2i operator *(right: int) 🔗

print(Vector2i(10, 20) / 2.9) # Prints "(5, 10)"
Vector2i operator /(right: int) 🔗

bool operator <(right: Vector2i) 🔗
Compares two Vector2i 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. This operator is useful for sorting vectors.
bool operator <=(right: Vector2i) 🔗
Compares two Vector2i 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. This operator is useful for sorting vectors.
bool operator ==(right: Vector2i) 🔗
Returns true if the vectors are equal.
bool operator >(right: Vector2i) 🔗
Compares two Vector2i 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. This operator is useful for sorting vectors.
bool operator >=(right: Vector2i) 🔗
Compares two Vector2i 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. This operator is useful for sorting vectors.
Access vector components using their index. v[0] is equivalent to v.x, and v[1] is equivalent to v.y.
Returns the same value as if the + was not there. Unary + does nothing, but sometimes it can make your code more readable.
Returns the negative value of the Vector2i. This is the same as writing Vector2i(-v.x, -v.y). This operation flips the direction of the vector while keeping the same magnitude.
