Description

🎲 RNGNeeds - The Ultimate Probability Distribution Plugin for Unity 🎲


🔥 UPDATE v0.9.9 - New Major Feature - Weighted Distribution 🔥


In addition to the default percentile-based workflow, you can now use weights to design probabilities. Weighted distribution has been a highly requested feature—a common RNG need our plugin aims to fulfill. Utilizing weights allows you to apply a tried-and-true approach to probability design, significantly expanding your game design options.



🔥 UPDATE v0.9.8 - New Major Feature - Depletable Lists 🔥


Depletable Lists are a powerful feature that allows items to have limited availability. By setting the maximum and available units for each item, you can unlock a wide range of possibilities for your game mechanics. Depletable items can be utilized in various ways, such as ensuring unique selections for game rewards or managing multiple instances of the same item, like in card decks or loot tables.



Take control of your random item drops, monster spawns, card decks, dice rolls, damage modifiers, or even organic animations using probability distribution with unparalleled simplicity and ease-of-use.


Visually author probability distribution of your NPC behaviors, dialogue choices, random encounters, ambient sounds, or character voice responses in a fully-customizable Inspector Drawer.


Enhance your game mechanics with Probability Influence Provider - an innovative concept that brings dynamic probability adjustment based on external factors.


🔥 GENERIC & USER FRIENDLY


  • Use with any value or reference type - no restrictions!
  • Visually author probabilities with a simple drag, scroll, or direct input.
  • Disable items from selection while keeping them in the list.
  • Lock probabilities to preserve odds when others are adjusted.
  • Customize info displays and themes individually for each drawer.

🚀 POWERFUL & ACCESSIBLE


  • Lightning-fast performance with burst-compiled selection methods.
  • All features are accessible via the Inspector and an easy-to-use API.
  • Extensible - easily implement your own Seed Providers or Selection Methods.

🎲 DYNAMIC & ADAPTABLE


  • Probability Influence - modify probabilities based on external factors.
  • Repeat Prevention techniques to avoid consecutive item selections.
  • Fixed or a variable pick count options with bias control.

"Every game thrives on an element of surprise, that tantalizing unpredictability that hooks players in. But managing this randomness, these 'RNG needs', is often more art than science. With RNGNeeds, you have a Unity plugin that redefines randomness, transforming it from a wild variable into a finely-tuned instrument of creativity."


Need to raise the odds of a critical strike based on player stats? Want to increase the chance of spawning that elite monster when it's close to midnight? Perhaps you need to drop health potions more often in tutorial scenarios.


"Beyond the dice rolls and item drops, RNGNeeds offers you a canvas of opportunity. Imagine dynamically adjusting the frequency of in-game storms as your player progresses through the storyline, modulating NPC behavior based on time of day, or making the battle more intense if the music volume is loud."


Experience RNGNeeds and unlock creative possibilities for your projects! 🚀


✨ ON THE ROADMAP ✨


Dynamic Probability Modification

Utilize multiple Mod Providers for items to dynamically manage probability adjustments and multipliers. (ie. crit chance +1.5% and/or *0.95)


Card Deck Extensions

A collection of handy methods to treat lists like card decks. Draw from the top/bottom, add cards, peek, cut decks, deal hands, or shuffle.

Technical details

Developed in Unity 2020 LTS and tested up to Unity 6 Preview.

Minimum Unity version: 2020.2


What does Beta mean for RNGNeeds?


RNGNeeds will remain in a Beta version for a short period following its release. All features planned for the v1 release have already been implemented and tested. However, as the plugin undergoes further real-world testing, certain aspects of feature usage or the API may undergo changes or optimizations.
