Game Logic and NPC
Powerd by Unreal Engine
NPCs
NPCs or Non Playable Characters are a key in every game with shared information like story, trade or tutorials. In some games NPCs are able to complete own tasks depending of daytime or mood independent of player interactions. This adds a own feeling to the game and makes it way more interesting than stationary NPCs with one line of audio.
In some cases are NPCs a vulnerable part of the game and can cause confusion and weird interactions. (That`s why some people who act weird are also called NPCs in some regions)
Character Models: You can create NPC models using 3D modeling tools and import them into Unreal Engine.
AI Controllers: Unreal Engine provides AI Controller classes that you can use to control the behavior of your NPCs.
Behavior Trees & Blackboards: These are tools provided by Unreal Engine for creating complex AI behaviors.
Logic!
Logic is the big hidden system what manages level handling, time data, current player stats and game progress. Its the most complex work on a project because its fits everything in a current outcome in real-time.
Most of the major bugs in games are hidden in the game logic.
That's why its most important to care by developing a game.
Game logic is the set of rules and systems that govern how your game works. This includes everything from player controls and game mechanics to scoring systems and level progression. In Unreal Engine, you can implement game logic using:
Blueprints: Unreal Engine’s visual scripting system, which allows you to create game logic without writing code.
C++: For more complex or performance-critical game logic, you can use Unreal Engine’s C++ API.
Your game logic will often interact with your NPCs. For example, an NPC might react differently depending on the game’s state, or the game state might change in response to an NPC’s actions. Unreal Engine provides various tools and systems to facilitate these interactions, such as the Event system in Blueprints and the AI Perception system for NPCs.
Remember, creating engaging game logic and believable NPCs is key to creating immersive games. Spend time planning and implementing these aspects of your game to ensure a great player experience.
