Logic Driver 2.0 Example Project

Requires Logic Driver 2.4.1 or higher and UE 4.25.3

• Make sure you are on UE 4.25.3 -- This hotfix corrects an issue building C++ projects with marketplace plugins.

Installation

1. Open the releases page or clone the repository using git clone --recurse-submodules
2. Download LogicDriverExample.zip

3. Open LogicDriverExample.uproject
4. Unreal should prompt to build the project
   • Visual Studio is required for the project to build. It can be downloaded from https://visualstudio.microsoft.com/downloads/
     • Make sure Game development with C++ is checked during the install. Otherwise building the project may fail

Installation & Walk-through Video

Documentation

• Logic Driver User Guide and API Reference

Example Map

• Basic state machine usage, contexts, and ticking
• Event based trigger with manual binding
• Event based trigger with auto binding
• Custom state class to print text and custom transition class with time delay
• Exposing a text variable with a default value, editing the default value, and using a text variable
• Dynamic instantiation of a state machine during run-time using custom classes and waiting for its completion
• State stack example of multiple state classes combined into one state node.

AI Example Map

• AI Patrol Behavior

Dialogue Example Map

• Sample Dialogue implementation using the LogicDriver-Dialogue Plugin
  • This is a submodule of this project and is required for this example
  • The plugin can be used as an example on how to overload state and transition classes in C++
• A dialogue system can be implemented entirely using Blueprints. See Dialogue System Concepts for more information

Quest Example Map

• Sample implementation of a simple fetch quest system. Each quest node is a state machine class containing quest objective state nodes.
• Behavior rules are setup so BP_QuestObjectiveNode states can only be placed in state machines of type BP_QuestStateMachine.
• First room runs sequential quests.
• Second room runs parallel quests.

Skill Example Map

• Demonstrates branching parallel states and leaving states active.

RPG Example Map [WIP]

• Demonstration of dialogue system interacting with an advanced quest system. Basic inventory system present (not made with Logic Driver).
