What is ReturnGraph?

<aside> <img src="/icons/question-mark_gray.svg" alt="/icons/question-mark_gray.svg" width="40px" />

ReturnGraph is a node-based plugin for Unity that lets you visualize logic to return values at runtime, without the need for endlessly nested If statements, Switch expressions, or other complicated coding logic. Think of it like a flowchart with dynamic variables for any type of value you need, right in your editor! ReturnGraph allows teams of all sizes, from the solo developer to a AAA studio, to create complex branching logic with a designer-friendly system, right in the inspector.

Combining the power of blackboard architecture and Unity's new Graph Toolkit API, ReturnGraph takes the confusion and tim sink out of creating large If statements with many branching pathways and variables, letting you spend more time designing (and finishing) your game!

ReturnGraph comes ready to go right out of the box with no additional dependencies or assets, and is preloaded with a suite of Nodes and Conditions to get you started. All you need to do is create a ReturnNode for the type of ScriptableObject you'd like to return, and then you're ready to start building your graph!

If your project requires custom Nodes or Conditions, don't worry! The C# source code is included, so ReturnGraph is easy to extend for your project's needs. Also detailed documentation and tutorials can be found both in the code and here!

Premade Nodes

• Start Node: tells the graph where to start
• Return Node: tells the graph to stop executing and return the node's referenced value
• Condition Node: evaluates a condition using dynamic or static values
• Switch Node: evaluates an enum value to select the next node
• Random Node: Randomly selects the next node
• Sequence Node: evaluates a series of conditions and selects the next node based on the first condition to return true
• Compound Condition Node: evaluates a series of conditions and selects the next node based on if every condition returns true, or if any condition returns true

Premade Conditions

• Bool Condition: evaluates a boolean value provided at runtime
• Integer Condition: evaluates an integer value (either provided at runtime or generated randomly) by comparing it to another integer
• Float Condition: evaluates a float value (either provided at runtime or generated randomly) provided at runtime by comparing it to another float
