KlakVS
KlakVS is an extension for visual scripting in Unity. It provides miscellaneous math functions useful for creating procedural behaviors.
- XXHash (deterministic random number generator)
- ExpTween/CdsTween (generic interpolator)
- Noise Source (fractional Brownian motion)
- On Keyboard Input (keyboard input with the new Input System)
XXHash
XXHash is a lightweight non-cryptographic hash function with which you can generate pseudo-random number sequences in a deterministic manner.
The XXHash unit generates a random number based on the two inputs -- Seed and Data. In our use case, Data simply works as a secondary random seed.
There are variants for different output types:
- XXHashInt
- XXHashFloat
- XXHashVector3
- XXHashDirection (uniformly distributed random points on a unit sphere)
- XXHashRotation (quaternion representing a random rotation)
ExpTween
The ExpTween unit implements an exponential interpolation function that is useful for creating ease-out animation.
A unique thing about ExpTween is that it doesn't require a control-flow connection. It's a stateless function, so that it works only with value connections.
There are variants for different types: ExpTweenFloat, ExpTweenVector3, and ExpTweenQuaternion.
CdsTween
The CdsTween unit implements a critically damped spring smoothing function that is useful for creating smooth ease-in/out animation.
There are variants for different types: CdsTweenFloat, CdsTweenVector3, and CdsTweenQuaternion.
NoiseSource
The NoiseSource unit implements a fractional Brownian motion (fBm) using a simplex noise function. It's useful to create natural wavy motion or undulation/vibration.
There are variants for different output types: NoiseSourceFloat, NoiseSourceVector3, NoiseSourceQuaternion.
OnKeyboardInput
The OnKeyboardInput unit is a simple replacement of the standard OnKeyboardInput unit but with the new Input System.
How to install the package
