Hermite interpolation between 0 and 1 when X is between Edge0 and Edge1. Smoother than a linear lerp.

Ken Perlin's improved smoothstep with zero 1st and 2nd derivatives at edges. Even smoother transitions.

Clamps an angle in degrees, correctly handling the 360/0 wraparound boundary.

Wraps an angle to the -180 to 180 range.

Checks if a float is approximately zero within tolerance.

Generates a damped sine wave. Useful for hit reactions, screen shake decay, and spring effects.

Evaluates a cubic bezier curve at parameter T using four control points.

Evaluates a cubic bezier curve in 3D space at parameter T.

Maintains a rolling average over the last N values. Automatically manages the history buffer.

Returns the Nth Fibonacci number using an iterative approach.

Returns the golden ratio constant phi.

Simulates a bouncing ball trajectory over a 0-1 alpha range.

Generates 1D Perlin-style noise at position X with an optional seed.

Generates 2D Perlin-style noise at position (X,Y).

Generates 3D Perlin-style noise at position (X,Y,Z).

Multi-octave fractal noise (fBm) for more natural-looking procedural generation.

Returns Value as a percentage of Total. Returns 0 if Total is zero.

Linearly interpolates between two angles, taking the shortest path across the 360/0 boundary.

Moves Current toward Target by at most MaxDelta. Will not overshoot.

Like MoveToward but handles angle wrapping correctly.

Returns the shortest signed difference between two angles in degrees.

Frame-rate-independent exponential interpolation. Faster than FInterpTo for many use cases.

Rounds up to the nearest multiple.

Rounds down to the nearest multiple.

Rounds to the nearest multiple.

Returns true if the integer is even.

Returns true if the integer is odd.

Returns true if the integer is a power of two.

Returns the smallest power of two >= Value.

Calculates the weighted average of an array of values with corresponding weights.

Calculates the standard deviation of an array of float values.

Cubic Hermite interpolation between P0 and P1 using tangents T0 and T1.

Applies a named easing curve to a 0–1 alpha value. Supports Linear, Quadratic, Cubic, Sine, Expo, Elastic, Bounce, and B...

Remaps a value from one range to another, then applies an easing curve to the result in one node.

Solves Ax² + Bx + C = 0. Returns the number of real roots (0, 1, or 2) and the root values.

Returns a deterministic random float in [Min, Max] driven by a seed. The same seed always produces the same value.

Returns a deterministic bool with the given probability of being true, driven by a seed.

Returns a deterministic integer in [Min, Max] driven by a seed. The same seed always produces the same value.
