Array & Collection

Picks a random item from an array using weighted probabilities.

Splits an array into chunks of the specified size. Last chunk may be smaller.

Returns an array with duplicate values removed, preserving order.

Flattens an array of arrays into a single flat array.

Combines two arrays into a map of key-value pairs. Arrays must be the same length.

Sorts an array of actors by a float property (via delegate). Uses introsort for guaranteed O(n log n).

Sorts an array of strings alphabetically.

Returns all contiguous sub-arrays of the given window size.

Returns the union of two arrays (all unique elements from both).

Returns elements present in both arrays.

Returns elements in ArrayA that are not in ArrayB.

Performs a binary search on a sorted array. Returns the index or -1.

Splits an array into two arrays: values less than pivot and values greater than or equal.

Returns the first N elements of an array.

Returns the array without the first N elements.

Rotates array elements by Offset positions. Positive rotates right, negative rotates left.

Interleaves two arrays (A[0], B[0], A[1], B[1], ...). Appends remaining elements if lengths differ.

Removes duplicate actors from an array, keeping the first occurrence.

Returns a random subset of N elements from the array without replacement.

Wraps an index to stay within array bounds (handles negative indices too).

Reverses a portion of an array between two indices.

Returns true if Array contains every element in Required.

Returns true if Array contains at least one element from Candidates.

Returns all indices where Value appears in the array.

Groups values by their corresponding key string.

Calculates start/end indices for processing a batch. Useful for spreading work across frames.

Counts how many times a value appears in an array.

Shuffles an integer array in place using Fisher-Yates. Use Seed=-1 for a random shuffle or any other value for a reprodu...

Extracts one page of items from a string array. Returns the items for the given zero-based page index and the total page...

Splits each string in the input array by the delimiter and collects all sub-strings into a single flattened output array...
