โ Supported Versions
Logic Driver Pro supports the latest official version of Unreal Engine. Advertised features apply to the most current release.
For full engine compatibility, visit the support page.
๐ ๏ธ Core Features
Developers can create custom nodes using blueprints or C++, exposing variables on the node and encapsulating reusable logic. Each node can include:
Editor Construction Scripts โ Dynamically update node properties in response to designer input.
Node Validation โ Provide visual warnings or prevent compilation when conditions arenโt met.
Rule Behavior โ Help enforce patterns and automate parts of the design process.
Designers may then use these nodes within Logic Driverโs state machine blueprints:
Easily add nodes with context-aware placement, with rule behavior limiting available state types or preselecting transition options.
Assign values to exposed properties by entering defaults directly or connecting variables, functions, or expressions.
Preview the system in the blueprint editor or debug it during Play In Editor (PIE).
โ๏ธ Advanced Capabilities
State Stack โ Combine multiple states in a sequence to execute tasks in order.
Transition Stack โ Quickly generate transition expressions between different transition types.
Parallel States โ Ideal for systems where multiple conditions or behaviors need to run at once.
Text Graph Properties โ Drag-and-drop variables directly onto text, with rich text and localization support.
Search Tool โ Find and replace property values across your project.
๐ Content Samples & Getting Started
Logic Driver Pro includes content samples with example setups and templates that can be easily added to your project.
Extensive documentation is available, including guides for general use, advanced features, and a complete API reference.
๐ Under the Hood
At its core, Logic Driver is a robust Finite State Machine (FSM) framework that evaluates transition conditions and executes state logic.
If you only need a lightweight state machine, try Logic Driver Lite (Free Version) to get a feel for the core system.
๐ Upgrading from Lite
Please make sure to uninstall the Lite version before installing Pro.
