Hi all,

## What is this and how do I contribute?

This is a list of Lua utility functions created by the Defold community. Functions should be generalized for use in any Defold project. Include a brief description of your function and be mindful of naming clarity. Please only include one function per reply for easy linking. If you have an alternative implementation of an already submitted function, please feel free to post it! I will keep the below list updated as best I can.

**Conversions**

Logarithmic Change of Base

Hex to Color

**Bounds Checking**

Clamp

Check Between Range

Check Within Rectangle

**Other**

Manhattan Distance

Sign of Number

Recursive Print

Low-Pass Filter (1) (2)

**External Libraries**

Happy Defolding!
