Variables
| Type | Name | Description | |
|---|---|---|---|
   |
bool | bNeedsToCache | Flag that indicates when we need to recompute our cached information. |
   |
FBox | CachedBounds | |
   |
TArray< FVector > | CachedSplinePoints | Cached list of points to describe the polygon given by the spline. |
   |
TArray< FVector2D > | CachedSplinePoints2D | Cached list of 2D points to describe the polygon given by the spline. |
  |
FPCGSplineStruct | SplineStruct | Minimal data needed to replicate the behavior from USplineComponent. |
Functions
| Type | Name | Description | |
|---|---|---|---|
 |
void | CacheData () |
Recompute cached data used for sampling. |
 |
void | Initialize
(
const UPCGSplineData* InSplineData |
|
  |
bool | PointInsidePolygon
(
const FTransform& InTransform, |
True if the given location falls in the top-down projection of the polygon given by our cached spline points. |

   |
FBox | GetBounds () |
Returns the full bounds (including density fall-off) of the data |
   |
FBox | Returns the bounds in which the density is always 1 | |
   |
bool | Returns true if the data has a non-trivial transform | |
   |
bool | IsBounded () |
Returns whether a given spatial data is bounded as some data types do not require bounds by themselves |
   |
bool | ProjectPoint
(
const FTransform& InTransform, |
Project the query point onto this data, and sample point and metadata information at the projected position. |
   |
bool | SamplePoint
(
const FTransform& Transform, |
Sample rotation, scale and other attributes from this data at the query position. |

void | AddToCrc
(
FArchiveCrc32& Ar, |
Adds this data to Crc. Fallback implementation writes object instance UID. |
