Arc

Base:

UBlueprintFunctionLibrary

Type:

UNArcPickerLibrary / FNArcPicker

Header File:

NexusActorPools/Public/NArcPickerLibrary.h

Provides various functions for generating points inside or on the surface of an arc using different random generation strategies (deterministic, non-deterministic, seeded).

The UNArcPickerLibrary wraps the native FNArcPicker functionality in a Blueprint friendly manner. Should you be wanting to utilize a picker in native code it is best to directly reference FNArcPicker directly to avoid the abstraction layer as it has a similar API.

Methods

Next Point

Gets the next deterministic point inside or on an FArc.

info

Uses FNRandom::Deterministic to ensure reproducible results.

Random Point

Gets a random point inside or on an arc.

info

Uses FNRandom::NonDeterministic to produce pseudo-random results.

One-Shot Point

Gets a random point inside or on an arc using a one-shot seed.

Tracked Point

Gets a random point inside or on an arc using a tracked seed. The seed altered for each Count.
