Vector4i
A 4D vector using integer coordinates.
描述
A 4-element structure that can be used to represent 4D grid coordinates or any other quadruplet of integers.
It uses integer coordinates and is therefore preferable to Vector4
when exact precision is required. Note that the values are limited to 32 bits, and unlike Vector4
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 Vector4i will evaluate to false
if it's equal to Vector4i(0, 0, 0, 0)
. Otherwise, a Vector4i will always evaluate to true
.

operator unary+ ( )
Returns the same value as if the +

does nothing, but sometimes it can make your code more readable.
Vector4i
operator unary- ( )
Returns the negative value of the Vector4i. This is the same as writing Vector4i(-v.x, -v.y, -v.z, -v.w)
. This operation flips the direction of the vector while keeping the same magnitude.
