pub struct GridCell<P: GridPrecision> {
pub x: P,
pub y: P,
pub z: P,
}Expand description
Defines the grid cell this entity’s Transform is relative to.
This component is generic over a few integer types to allow you to select the grid size you need. These correspond to a total usable volume of a cube with the following edge lengths:
Assuming you are using a grid cell edge length of 10,000 meters, and 1.0 == 1 meter
- i8: 2,560 km = 74% of the diameter of the Moon
- i16: 655,350 km = 85% of the diameter of the Moon’s orbit around Earth
- i32: 0.0045 light years = ~4 times the width of the solar system
- i64: 19.5 million light years = ~100 times the width of the milky way galaxy
- i128: 3.6e+26 light years = ~3.9e+15 times the width of the observable universe
where
usable_edge_length = 2^(integer_bits) * grid_cell_edge_length
Note
Be sure you are using the same grid index precision everywhere. It might be a good idea to define a type alias!
type GalacticGrid = GridCell<i64>;Fields§
§x: PThe x-index of the cell.
y: PThe y-index of the cell.
z: PThe z-index of the cell.
