RV Smart Ai

RV SmartAI is a lightweight, flexible and high-performance utility AI framework. With SmartAI you’ll be able to visually model complex AI behaviours for your game with ease.

SmartAI and HonorAI comparison table

It can be integrated into any project, regardless of stage, as it doesn’t force you to refactor all of your existing AI code, and can easily coexist and support your already implemented AI logic. Transfer only what you want of your game’s logic to SmartAI! For example you can leave your AIs movement logic untouched, and implement just your fighting logic, or even only target selection logic via AI graphs.

SmartAI is the only graph-based utility AI solution on the asset store that fully supports prefab workflows in AI design process: create reusable graphs, nodes and even single graph elements, using Unity’s powerful prefab variants and property overrides.

Full runtime editing support makes fine-tuning values for utilities so much faster and easier, as you have real time feedback on how changes you're making affects your AI behaviour.

One of the biggest advantage of utility AI concept over FSMs or behaviour trees is that it’s much more scalable in terms of complexity while remaining simple and easy to maintain, understand decision process and debug.

► Visual node graph editor - write your AI behaviours in C# and play with them like legos

► As easy to use as behaviour trees while being much more scalable in terms of complexity

► Easily integrated into existing projects, regardless of stage

► Doesn’t force you to refactor all of your existing logic, only parts you want to

► User friendly and easy to use

► High performance and load balanced

► Runtime visual debugging

► C# source for all modules!

► Runtime graph modifications - see changes in your AI behaviours in real time and save a lot of time tweaking values

► Fully supports Unity prefab system - including nesting, variants and property overrides for graphs and all graph elements

► Unity’s undo system support

► Core system has no runtime allocations after initialization

► Written with flexibility and scalability in mind, as separate modules

► Many independent modules included in package

► Can be made to run on own threads (core system doesn’t use Unity API)

► Lot of script templates and base classes for common usages

► No subscription, no seats limits, buy once and use freely

Tested on Windows and Android platforms.

Release Notes

10.2019

1.0

-first release

10.2019

1.1

-Unity 2019 support

-updated modules: new api for managing load balancing; now you don't need to have 'SmartAIUpdater' object on scene

-update frequency can be set separately for every ai thanks to new load balancing api

-general code cleanup and improved encapsulation in provided examples

01.2020

1.2

Features:

-graph elements copying, pasting and duplicating, from node's context menu

-tool for analysis and automatic fixing of AiGraph

-debugging last score for single scorers in inspector

-new set of scorers and tasks that are reflection based, see RVModules\RVSmartAI\Content\Code\AI\ReflectionBased\

allowing to manipulate public properties on context and AiTaskParams parameters via ai graphs

-scorer types: now you can select math operation for every scorer: add, sub, multiply or divide.

It operates on result score from all earlier scorers, so if the last scorer is divide, it will divide whole returning score by its own score.

Fixes:

-graph is destroyed on Ai component OnDestroy

-script templates using public instead of protected access modifier

-AiTaskParams - scores below 0 will work properly now

-AiTaskParams disabling fix

-general code cleanup

05.2020

1.2.1

-added button to fold nodes in graph

07.2020

1.3

Features:

-secondary graphs

-nested graphs system

-new node type: graph node for referencing other graphs

-search bar for adding scorers and tasks windows

-ai jobs system

-AiTask can now have scorers just like AiUtility

Improvements:

-automatic and more consistent graph elements' game objects naming

-lost references to child graph element now automatically fixed

-automatic null child graph elements removing

-updated RVLoadBalancer and RVUtilities modules to newest version

-improvements in movement physx scanner

Fixes:

-fixed node connection lines not centered in connection ports

-fixed copying/duplicating nodes in variant graph

Changes:

-all scorers default score is 1 instead of 0

-changed max slider value for graph update frequency from 30 to 8

-removed graphStepsPerUpdate from inspector, by default all graphs will now go through all nodes in one update as there is very little to gain

by not going through whole graph in every update and it makes ai behaviour inconsistent

09.2020

1.4

Features:

-data providers

-graph variables

-ai references

-running ai tasks - every ai task can now 'block' execution of graph until it's finished

-new tasks and scorers using data providers and load balanced execution

-load balanced scan method for physx movement scanner (can spread scanning across multiple frames for better performance)

-default description for AiGraphElement - now you can define graph element's default description in code

Improvements:

-custom ai load balancer configuration available from inspector and via api

-improved spatial scanners

-many new api comments and updated documentation

-performance improvements in load balancing module

Changes:

-SmartAiExposeField is made obsolete, no need to use it anymore, from now all serialized fields are exposed just like in any other Monobehaviour

-some namespaces refactor

10.2020

1.41

Improvements:

-real time debug info of graph variables in AI inspector for main graph and secondary graphs

-optimized memory allocations in many places

-added button in runtime debugging that selects graph owner

Fixes:

-removed rest of obsolete RVSmartAiExposeField attributes

-nested graphs will get destroyed when parent graph was destroyed

-secondary graphs game objects will get destroyed

-fixed runtime debug node connections highlight for running tasks

Changes:

-removed 'debug info' showing last evaluated node utility and task from Ai inspector

-changed GraphVariables class name to Variables

-AiScanSurrounding task is using FloatProvider instead of normal float for scanRange

-AiTask StartExecuting now have return value of bool, to decide if running task was actually started or should be ignored

-MoveToBestPosition divided into two different classes for better control: ScanAndMoveToBestPosition(earlier MoveToBestPosition) and new - MoveToBestPosition

that works on earlier prepared list of positions; this setup allows to have position scanning and scoring as separate tasks

(one that scans positions(ScanWalkablePositions) and other that scores them and moves to best one(MoveToBestPosition))

02.2021

1.42

Features:

-new data providers: string provider

-new data providers: LayerMask provider

-new task: DebugLogTask - logs provided string

-added layer masks to AiVariables

Fixes:

-fixed sub graphs execution bug

-fixed displaying "I" next to every input node

Changes:

-class Variables changed to AiVariables

-AiTask: default returned value of StartExecuting method is now true instead of false

-removed output connection port from GraphNodes

03.2021

1.45

Features:

-new node: ConditionNode - simple lightweight node with just one scorer and two outputs: True and False

-new graph elements: Block - will just block execution of graph, DebugBreakTask - calls Debug.Break() on execution, work as break point in IDE

-extracted VisualDebugger<T> as abstract base class for visual debuggers

Fixes:

-data provider context initialization when added at runtime
