Calculates final damage after armor, resistance, and critical hit modifiers.

Calculates per-tick damage and total tick count for a damage-over-time effect.

Finds the closest actor of a specified class to a given point.

Spawns or retrieves a pooled actor. If a deactivated pooled actor exists, reactivates and repositions it.

Returns an actor to its object pool (deactivates and hides it).

Calculates a unit's position in a formation (Circle, Line, Wedge, Column, Staggered).

Calculates an aggro/threat score for AI targeting decisions.

Performs a weighted random roll on a loot table. Keys are item names, values are weights.

Calculates the level from total XP using an exponential curve (XP needed = BaseXP * Level^ExponentFactor).

Returns the total XP required to reach a given level.

Performs a line trace to check if there is a clear line of sight between two points.

Evaluates how well a position provides cover from a threat by performing multiple traces.

Traces downward at a location to determine the physical surface type.

Applies a knockback impulse to an actor's movement component.

Calculates damage with distance-based falloff (linear, quadratic, etc.).

Calculates where to aim to hit a moving target with a projectile of known speed.

Checks if an actor is facing a target location within a tolerance angle.

Traces downward to find the ground and returns the height above it.

Returns the angle between each actor's forward vector and the direction to the other actor.

Smoothly interpolates an actor toward a target transform. Returns true when approximately reached.

Filters an array of actors into those visible and those hidden from a point.

Spawns a projectile actor with initial velocity set from direction and speed.

Returns the character's current movement direction (normalized velocity) and speed.

Sorts an array of actors by distance from a reference point, nearest first.

Returns the first actor in the world with the given tag, or null if none found.

Returns all actors within an axis-aligned box region. Useful for area-of-effect queries.

Returns all actors within a sphere radius using an overlap query.

Returns an actor's world-space bounding box as center and half-extent.

Returns true if two actors' bounding boxes are intersecting.

Returns an actor's FName tags converted to a string array.
