Circle

Base:

UBlueprintFunctionLibrary

Type:

UNCirclePickerLibrary / FNCirclePicker

Header File:

NexusActorPools/Public/NCirclePickerLibrary.h

Provides various functions for generating points in the plane of a circle using different random generation strategies (deterministic, non-deterministic, seeded).

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

Methods

Next Point (IO)

Generates a deterministic point [i]nside or [o]n the perimeter of a circle.

info

Uses FNRandom::Deterministic to ensure reproducible results.

Next Point Projected (IO)

Generates a deterministic point [i]nside or [o]n the perimeter of a circle, then projects it to the world. The point is projected in the given direction until it hits something in the world.

info

Uses FNRandom::Deterministic to ensure reproducible results.

Random Point (IO)

Generates a random point [i]nside or [o]n the perimeter of a circle. Uses the non-deterministic random generator for true randomness.

Random Point Projected (IO)

Generates a random point [i]nside or [o]n the perimeter of a circle, then projects it to the world. The point is projected in the given direction until it hits something in the world.

Random One-Shot Point (IO)

Generates a random point [i]nside or [o]n the perimeter of a circle using a provided seed. Useful for one-time random point generation with reproducible results.

Random One-Shot Point Projected (IO)

Generates a random point [i]nside or [o]n the perimeter of a circle using a provided seed, then projects it to the world. The point is projected in the given direction until it hits something in the world.

Random Tracked Point (IO)

Generates a random point [i]nside or [o]n the perimeter of a circle while tracking the random seed state. Updates the seed value to enable sequential random point generation.

Random Tracked Point Projected (IO)

Generates a random point [i]nside or [o]n the perimeter of a circle while tracking the random seed state, then projects it to the world. Updates the seed value to enable sequential random point generation. The point is projected in the given direction until it hits something in the world.
