What Are DST Game Scripts?

Don't Starve Together (DST) is built on a comprehensive Lua scripting system that defines virtually every aspect of the game's behavior. These scripts form the backbone of DST's gameplay mechanics, user interface, artificial intelligence, world generation, and modding capabilities.

The game scripts serve as both:

• Game Logic Implementation: Core systems that make DST function
• Modding Framework: Foundation that enables community modifications and customizations

Why Lua Scripts Matter

1. Flexibility and Customization

DST's Lua-based architecture allows for:

• Dynamic gameplay modifications without engine recompilation
• Real-time testing and iteration of game mechanics
• Extensive modding capabilities for the community
• Easy configuration and tuning of game parameters

2. Modular Design

The script system organizes functionality into discrete, reusable components:

• Components: Reusable functionality attached to entities (health, inventory, combat)
• Prefabs: Complete entity definitions (characters, items, structures)
• Stategraphs: Animation and behavior state management
• Brains: AI decision-making systems

3. Community Empowerment

The accessible Lua scripting system enables:

• Thousands of community-created mods
• Custom game modes and challenges
• Quality-of-life improvements and features
• Educational opportunities for learning game development

Script System Architecture

Core Script Categories

Category	Purpose	Examples
Components	Reusable entity behaviors	Health, Inventory, Combat, Cooking
Prefabs	Complete entity definitions	Characters, Items, Structures, Creatures
Stategraphs	Animation and state management	Player actions, creature behaviors
Brains	AI decision-making logic	Creature AI, NPC behaviors
Behaviours	Reusable AI patterns	Approach target, flee danger, wander
Widgets	User interface elements	Buttons, panels, inventory displays
Screens	Full screen interfaces	Main menu, crafting screens, settings

Understanding the Codebase

File Organization

The DST scripts are organized in a logical hierarchy:

dst-scripts/
├── components/          # Reusable entity functionality
├── prefabs/            # Complete entity definitions  
├── stategraphs/        # Animation and state management
├── brains/             # AI decision-making systems
├── behaviours/         # Reusable AI patterns
├── widgets/            # UI components
├── screens/            # Full screen interfaces
├── map/                # World generation systems
└── util/               # Utility functions and helpers

Script Interconnections

DST scripts work together through well-defined interfaces:

1. Entity-Component System: Entities (prefabs) are composed of multiple components that provide specific functionality
2. Event System: Components communicate through events, enabling loose coupling
3. State Management: Stategraphs manage entity animations and behavioral states
4. AI Framework: Brains coordinate behaviors to create intelligent entity actions

Learning Path for DST Scripts

1. Start with Components

• Understand how components provide functionality to entities
• Learn common patterns like health, inventory, and transform components
• Practice reading component implementations

2. Explore Prefabs

• See how components combine to create complete entities
• Understand prefab construction and initialization
• Learn about tags, physics, and entity relationships

3. Study Stategraphs

• Learn how animations and states are managed
• Understand state transitions and timeline events
• See how player actions are implemented

4. Examine AI Systems

• Explore how brains coordinate entity behavior
• Understand the relationship between brains and behaviours
• Learn how AI decisions are made and executed

Common Script Patterns

Component Pattern

-- Components provide reusable functionality
local MyComponent = Class(function(self, inst)
    self.inst = inst
    self.value = 0
end)

function MyComponent:SetValue(val)
    self.value = val
    self.inst:PushEvent("valuechanged", {value = val})
end

Event-Driven Communication

-- Components communicate through events
inst:ListenForEvent("healthdelta", function(inst, data)
    -- React to health changes
    if data.newpercent <= 0.25 then
        inst:AddTag("low_health")
    end
end)

Prefab Construction

-- Prefabs combine components into complete entities
local function CreateMyEntity()
    local inst = CreateEntity()
    
    -- Add components
    inst:AddComponent("health")
    inst:AddComponent("inventory")
    inst:AddComponent("combat")
    
    -- Configure components
    inst.components.health:SetMaxHealth(100)
    
    return inst
end
