ECS (Entity Component System) is Unity's data-oriented framework. It replaces the GameObject/MonoBehaviour model with a cache-friendly, high-performance architecture.
| Aspect | MonoBehaviour | ECS |
|---|---|---|
| Identity | GameObject (heavy, managed) | Entity (lightweight int ID) |
| Data | Class fields on components | Unmanaged structs (IComponentData) |
| Logic | Methods on MonoBehaviour | Systems (ISystem / SystemBase) |
| Memory layout | Scattered across heap | Contiguous chunks by archetype |
| Threading | Main thread only | Jobs + Burst for parallel work |
Entities are lightweight identifiers (an index + version integer). They have no behavior and no data -- they are handles used to associate components.
Components are unmanaged structs with no methods. They hold only data.
using Unity.Entities;
public struct Speed : IComponentData
{
public float Value;
}
public struct Health : IComponentData
{
public float Current;
public float Max;
}
An archetype is a unique combination of component types. All entities with the same set of components share an archetype. Entities are stored in chunks (16 KB blocks) grouped by archetype, enabling cache-efficient iteration.
A World contains an EntityManager and a set of systems. The default world is created automatically. EntityManager is the primary API for creating/destroying entities and adding/removing components.
Baking converts authoring GameObjects into runtime entities. This is a one-way conversion that happens at build time or when a SubScene is loaded in the Editor.
using Unity.Entities;
// Authoring component (MonoBehaviour on GameObject)
public class SpeedAuthoring : MonoBehaviour
{
public float speed;
}
// Baker converts authoring data to ECS components
public class SpeedBaker : Baker<SpeedAuthoring>
{
public override void Bake(SpeedAuthoring authoring)
{
var entity = GetEntity(TransformUsageFlags.Dynamic);
AddComponent(entity, new Speed { Value = authoring.speed });
}
}
| Flag | Use |
|---|---|
Dynamic | Entity moves at runtime (gets LocalTransform, LocalToWorld) |
Renderable | Entity is rendered but not moved by code |
WorldSpace | Entity uses world-space transform only |
None | No transform components added |
Systems contain all logic. They iterate over entities that match a component query.
ISystem is the modern, unmanaged system type. It is Burst-compatible and should be preferred over SystemBase.

}
[BurstCompile]

{

}
}
[BurstCompile]
public void OnDestroy(ref SystemState state) { }
}
Key points:
partial struct[BurstCompile] on the struct and each methodOnCreate, OnUpdate, OnDestroy receive ref SystemStatestate.RequireForUpdate<T>() -- system only runs when T existsSystemAPI.Query<T>() -- type-safe foreach iterationSystemBase is a managed class-based system. It supports managed code but cannot be Burst-compiled at the system level. Use ISystem for all new code. SystemBase uses Entities.ForEach() lambda syntax instead of SystemAPI.Query.
Systems are organized into groups that update in a defined order:
InitializationSystemGroup
-> BeginInitializationEntityCommandBufferSystem
SimulationSystemGroup (default group)
-> BeginSimulationEntityCommandBufferSystem
-> [Your systems go here by default]
-> EndSimulationEntityCommandBufferSystem
PresentationSystemGroup
-> BeginPresentationEntityCommandBufferSystem
Control ordering with attributes:
[UpdateInGroup(typeof(SimulationSystemGroup))]
[UpdateBefore(typeof(OtherSystem))]
[UpdateAfter(typeof(AnotherSystem))]
public partial struct MySystem : ISystem { }
SystemAPI provides static methods for safe, Burst-compatible access:
| Method | Purpose |
|---|---|
SystemAPI.Query<T1, T2>() | Iterate matching entities |
SystemAPI.Time | Access TimeData (DeltaTime, ElapsedTime) |
SystemAPI.GetSingleton<T>() | Get singleton component value |
SystemAPI.SetSingleton<T>(value) | Set singleton component value |
SystemAPI.GetComponent<T>(entity) | Read component from entity |
SystemAPI.SetComponent<T>(entity, value) | Write component on entity |
SystemAPI.HasComponent<T>(entity) | Check if entity has component |
SystemAPI.GetComponentLookup<T>() | Get random-access lookup |
SystemAPI.GetBuffer<T>(entity) | Get DynamicBuffer |
SystemAPI.GetAspect<T>(entity) | Get aspect for entity |
The fundamental component type. Must be an unmanaged struct (no reference types, no managed arrays).
Shared across entities -- entities with the same shared component value are grouped into the same chunk. Changing a shared component value is a structural change.
public struct TeamId : ISharedComponentData
{
public int Value;
}
Variable-length arrays attached to entities.
[InternalBufferCapacity(8)]
public struct DamageEvent : IBufferElementData
{
public float Value;
public Entity Source;
}
// Usage in a system
foreach (var (buffer, entity) in SystemAPI.Query<DynamicBuffer<DamageEvent>>()
.WithEntityAccess())
{
for (int i = 0; i < buffer.Length; i++)
totalDamage += buffer[i].Value;
buffer.Clear();
}
Persists after entity destruction. Used for cleanup logic (e.g., releasing native resources). The entity is not fully destroyed until all cleanup components are removed.
Components that can be toggled on/off without structural changes (no chunk moves).
public struct Stunned : IComponentData, IEnableableComponent { }
// Toggle in system
SystemAPI.SetComponentEnabled<Stunned>(entity, true);
bool isStunned = SystemAPI.IsComponentEnabled<Stunned>(entity);
Zero-size structs used purely for filtering queries. No fields -- zero memory cost per entity.
public struct IsPlayer : IComponentData { }
// Direct creation (structural change -- main thread only)
Entity e = entityManager.CreateEntity(typeof(Speed), typeof(Health));
// Preferred: use EntityCommandBuffer for deferred structural changes
var ecb = new EntityCommandBuffer(Allocator.TempJob);
Entity e2 = ecb.CreateEntity();
ecb.AddComponent(e2, new Speed { Value = 5f });
ecb.Playback(entityManager);
ecb.Dispose();
Structural changes (create/destroy entity, add/remove component) cannot happen during iteration. Use ECB to defer them. See references/ecs-api.md for full ECB API.
[BurstCompile]
public partial struct SpawnSystem : ISystem
{
[BurstCompile]
public void OnUpdate(ref SystemState state)
{
var ecbSingleton = SystemAPI.GetSingleton<
EndSimulationEntityCommandBufferSystem.Singleton>();
var ecb = ecbSingleton.CreateCommandBuffer(state.WorldUnmanaged);
// ecb is played back automatically -- no Playback/Dispose needed
foreach (var spawner in SystemAPI.Query<RefRW<Spawner>>())
{
if (spawner.ValueRO.Timer <= 0)
{
ecb.Instantiate(spawner.ValueRO.Prefab);
spawner.ValueRW.Timer = spawner.ValueRO.Interval;
}
}
}
}
Use when exactly one entity has a given component. Access via SystemAPI.GetSingleton<T>() / SystemAPI.SetSingleton<T>(value) / SystemAPI.GetSingletonRW<T>(). Useful for global config, game state, and similar one-of-a-kind data.
Aspects group related components into a single access wrapper with optional methods.
public readonly partial struct CharacterAspect : IAspect
{
public readonly RefRW<LocalTransform> Transform;
public readonly RefRO<Speed> Speed;
public readonly RefRW<Health> Health;
public void Move(float3 direction, float deltaTime)
{
Transform.ValueRW.Position +=
direction * Speed.ValueRO.Value * deltaTime;
}
}
// Use in system
foreach (var character in SystemAPI.Query<CharacterAspect>())
{
character.Move(new float3(1, 0, 0), deltaTime);
}
Automatically generates an EntityQuery from the Execute parameter types.
[BurstCompile]
public partial struct MoveJob : IJobEntity
{
public float DeltaTime;
void Execute(ref LocalTransform transform, in Speed speed)
{
transform.Position += new float3(0, 0, speed.Value * DeltaTime);
}
}
// Schedule from system
[BurstCompile]
public partial struct MoveSystem : ISystem
{
[BurstCompile]
public void OnUpdate(ref SystemState state)
{
new MoveJob
{
DeltaTime = SystemAPI.Time.DeltaTime
}.ScheduleParallel();
}
}
Manual chunk iteration for maximum control. See references/jobs-burst.md for full examples.
| Method | Behavior |
|---|---|
Run() | Execute on main thread (no job scheduling) |
Schedule() | Single-threaded job on worker thread |
ScheduleParallel() | Multi-threaded across chunks |
[BurstCompile]
public partial struct DestroyDeadJob : IJobEntity
{
public EntityCommandBuffer.ParallelWriter ECB;
void Execute([ChunkIndexInQuery] int sortKey, in Health health, Entity entity)
{
if (health.Current <= 0)
ECB.DestroyEntity(sortKey, entity);
}
}
The Burst compiler translates IL/.NET bytecode into highly optimized native code using LLVM.
Add [BurstCompile] to ISystem structs (and each method) and IJobEntity structs. Burst compiles them to optimized native code via LLVM.

# Unity ECS / DOTS (Data-Oriented Technology Stack)
> Based on Unity 6.3 LTS (6000.3) -- Entities 1.3, Burst 1.8, Jobs package
## Core Concepts
ECS (Entity Component System) is Unity's data-oriented framework. It replaces the GameObject/MonoBehaviour model with a cache-friendly, high-performance architecture.
### ECS vs MonoBehaviour
| Aspect | MonoBehaviour | ECS |
|--------|--------------|-----|
| Identity | GameObject (heavy, managed) | Entity (lightweight int ID) |
| Data | Class fields on components | Unmanaged structs (IComponentData) |
| Logic | Methods on MonoBehaviour | Systems (ISystem / SystemBase) |
| Memory layout | Scattered across heap | Contiguous chunks by archetype |
| Threading | Main thread only | Jobs + Burst for parallel work |
### Entities
Entities are lightweight identifiers (an index + version integer). They have no behavior and no data -- they are handles used to associate components.
### Components (IComponentData)
Components are unmanaged structs with no methods. They hold only data.
```csharp
using Unity.Entities;
public struct Speed : IComponentData
{
public float Value;
}
public struct Health : IComponentData
{
public float Current;
public float Max;
}
```
### Archetypes and Chunks
An **archetype** is a unique combination of component types. All entities with the same set of components share an archetype. Entities are stored in **chunks** (16 KB blocks) grouped by archetype, enabling cache-efficient iteration.
### World and EntityManager
A `World` contains an `EntityManager` and a set of systems. The default world is created automatically. `EntityManager` is the primary API for creating/destroying entities and adding/removing components.
## Baking and SubScene Workflow
Baking converts authoring GameObjects into runtime entities. This is a one-way conversion that happens at build time or when a SubScene is loaded in the Editor.
### Baker<T>
```csharp
using Unity.Entities;
// Authoring component (MonoBehaviour on GameObject)
public class SpeedAuthoring : MonoBehaviour
{
public float speed;
}
// Baker converts authoring data to ECS components
public class SpeedBaker : Baker<SpeedAuthoring>
{
public override void Bake(SpeedAuthoring authoring)
{
var entity = GetEntity(TransformUsageFlags.Dynamic);
AddComponent(entity, new Speed { Value = authoring.speed });
}
}
```
### SubScene
- SubScenes contain GameObjects that are baked into entities at build time
- At runtime, entity data streams in efficiently (no GameObject overhead)
- In the Editor, SubScenes can be opened for editing (shows GameObjects) or closed (shows baked entities)
- Always place ECS-managed objects inside a SubScene
### TransformUsageFlags
| Flag | Use |
|------|-----|
| `Dynamic` | Entity moves at runtime (gets LocalTransform, LocalToWorld) |
| `Renderable` | Entity is rendered but not moved by code |
| `WorldSpace` | Entity uses world-space transform only |
| `None` | No transform components added |
## Systems
Systems contain all logic. They iterate over entities that match a component query.
### ISystem (Recommended)
ISystem is the modern, unmanaged system type. It is Burst-compatible and should be preferred over SystemBase.
```csharp
using Unity.Burst;
using Unity.Entities;
using Unity.Mathematics;
using Unity.Transforms;
[BurstCompile]
public partial struct MovementSystem : ISystem
{
[BurstCompile]
public void OnCreate(ref SystemState state)
{
state.RequireForUpdate<Speed>();
}
[BurstCompile]
public void OnUpdate(ref SystemState state)
{
float deltaTime = SystemAPI.Time.DeltaTime;
foreach (var (transform, speed) in
SystemAPI.Query<RefRW<LocalTransform>, RefRO<Speed>>())
{
transform.ValueRW.Position +=
new float3(0, 0, speed.ValueRO.Value * deltaTime);
}
}
[BurstCompile]
public void OnDestroy(ref SystemState state) { }
}
```
**Key points:**
- Must be a `partial struct`
- Use `[BurstCompile]` on the struct and each method
- `OnCreate`, `OnUpdate`, `OnDestroy` receive `ref SystemState`
- `state.RequireForUpdate<T>()` -- system only runs when T exists
- `SystemAPI.Query<T>()` -- type-safe foreach iteration
### SystemBase (Managed, Legacy)
SystemBase is a managed class-based system. It supports managed code but cannot be Burst-compiled at the system level. Use ISystem for all new code. SystemBase uses `Entities.ForEach()` lambda syntax instead of `SystemAPI.Query`.
### SystemGroup and Update Ordering
Systems are organized into groups that update in a defined order:
```
InitializationSystemGroup
-> BeginInitializationEntityCommandBufferSystem
SimulationSystemGroup (default group)
-> BeginSimulationEntityCommandBufferSystem
-> [Your systems go here by default]
-> EndSimulationEntityCommandBufferSystem
PresentationSystemGroup
-> BeginPresentationEntityCommandBufferSystem
```
Control ordering with attributes:
```csharp
[UpdateInGroup(typeof(SimulationSystemGroup))]
[UpdateBefore(typeof(OtherSystem))]
[UpdateAfter(typeof(AnotherSystem))]
public partial struct MySystem : ISystem { }
```
### SystemAPI
`SystemAPI` provides static methods for safe, Burst-compatible access:
| Method | Purpose |
|--------|---------|
| `SystemAPI.Query<T1, T2>()` | Iterate matching entities |
| `SystemAPI.Time` | Access TimeData (DeltaTime, ElapsedTime) |
| `SystemAPI.GetSingleton<T>()` | Get singleton component value |
| `SystemAPI.SetSingleton<T>(value)` | Set singleton component value |
| `SystemAPI.GetComponent<T>(entity)` | Read component from entity |
| `SystemAPI.SetComponent<T>(entity, value)` | Write component on entity |
| `SystemAPI.HasComponent<T>(entity)` | Check if entity has component |
| `SystemAPI.GetComponentLookup<T>()` | Get random-access lookup |
| `SystemAPI.GetBuffer<T>(entity)` | Get DynamicBuffer |
| `SystemAPI.GetAspect<T>(entity)` | Get aspect for entity |
## Components Deep Dive
### IComponentData (Unmanaged Struct)
The fundamental component type. Must be an unmanaged struct (no reference types, no managed arrays).
### ISharedComponentData
Shared across entities -- entities with the same shared component value are grouped into the same chunk. Changing a shared component value is a structural change.
```csharp
public struct TeamId : ISharedComponentData
{
public int Value;
}
```
### IBufferElementData (DynamicBuffer)
Variable-length arrays attached to entities.
```csharp
[InternalBufferCapacity(8)]
public struct DamageEvent : IBufferElementData
{
public float Value;
public Entity Source;
}
// Usage in a system
foreach (var (buffer, entity) in SystemAPI.Query<DynamicBuffer<DamageEvent>>()
.WithEntityAccess())
{
for (int i = 0; i < buffer.Length; i++)
totalDamage += buffer[i].Value;
buffer.Clear();
}
```
### ICleanupComponentData
Persists after entity destruction. Used for cleanup logic (e.g., releasing native resources). The entity is not fully destroyed until all cleanup components are removed.
### IEnableableComponent
Components that can be toggled on/off without structural changes (no chunk moves).
```csharp
public struct Stunned : IComponentData, IEnableableComponent { }
// Toggle in system
SystemAPI.SetComponentEnabled<Stunned>(entity, true);
bool isStunned = SystemAPI.IsComponentEnabled<Stunned>(entity);
```
### Tag Components
Zero-size structs used purely for filtering queries. No fields -- zero memory cost per entity.
```csharp
public struct IsPlayer : IComponentData { }
```
## Common Patterns
### Creating and Destroying Entities
```csharp
// Direct creation (structural change -- main thread only)
Entity e = entityManager.CreateEntity(typeof(Speed), typeof(Health));
// Preferred: use EntityCommandBuffer for deferred structural changes
var ecb = new EntityCommandBuffer(Allocator.TempJob);
Entity e2 = ecb.CreateEntity();
ecb.AddComponent(e2, new Speed { Value = 5f });
ecb.Playback(entityManager);
ecb.Dispose();
```
### EntityCommandBuffer (ECB)
Structural changes (create/destroy entity, add/remove component) cannot happen during iteration. Use ECB to defer them. See [references/ecs-api.md](references/ecs-api.md) for full ECB API.
### System-Managed ECB (Preferred)
```csharp
[BurstCompile]
public partial struct SpawnSystem : ISystem
{
[BurstCompile]
public void OnUpdate(ref SystemState state)
{
var ecbSingleton = SystemAPI.GetSingleton<
EndSimulationEntityCommandBufferSystem.Singleton>();
var ecb = ecbSingleton.CreateCommandBuffer(state.WorldUnmanaged);
// ecb is played back automatically -- no Playback/Dispose needed
foreach (var spawner in SystemAPI.Query<RefRW<Spawner>>())
{
if (spawner.ValueRO.Timer <= 0)
{
ecb.Instantiate(spawner.ValueRO.Prefab);
spawner.ValueRW.Timer = spawner.ValueRO.Interval;
}
}
}
}
```
### Singleton Components
Use when exactly one entity has a given component. Access via `SystemAPI.GetSingleton<T>()` / `SystemAPI.SetSingleton<T>(value)` / `SystemAPI.GetSingletonRW<T>()`. Useful for global config, game state, and similar one-of-a-kind data.
### Aspects (IAspect)
Aspects group related components into a single access wrapper with optional methods.
```csharp
public readonly partial struct CharacterAspect : IAspect
{
public readonly RefRW<LocalTransform> Transform;
public readonly RefRO<Speed> Speed;
public readonly RefRW<Health> Health;
public void Move(float3 direction, float deltaTime)
{
Transform.ValueRW.Position +=
direction * Speed.ValueRO.Value * deltaTime;
}
}
// Use in system
foreach (var character in SystemAPI.Query<CharacterAspect>())
{
character.Move(new float3(1, 0, 0), deltaTime);
}
```
## Jobs System
### IJobEntity (Recommended)
Automatically generates an EntityQuery from the Execute parameter types.
```csharp
[BurstCompile]
public partial struct MoveJob : IJobEntity
{
public float DeltaTime;
void Execute(ref LocalTransform transform, in Speed speed)
{
transform.Position += new float3(0, 0, speed.Value * DeltaTime);
}
}
// Schedule from system
[BurstCompile]
public partial struct MoveSystem : ISystem
{
[BurstCompile]
public void OnUpdate(ref SystemState state)
{
new MoveJob
{
DeltaTime = SystemAPI.Time.DeltaTime
}.ScheduleParallel();
}
}
```
### IJobChunk (Low-Level)
Manual chunk iteration for maximum control. See [references/jobs-burst.md](references/jobs-burst.md) for full examples.
### Job Scheduling
| Method | Behavior |
|--------|----------|
| `Run()` | Execute on main thread (no job scheduling) |
| `Schedule()` | Single-threaded job on worker thread |
| `ScheduleParallel()` | Multi-threaded across chunks |
### ECB in Parallel Jobs
```csharp
[BurstCompile]
public partial struct DestroyDeadJob : IJobEntity
{
public EntityCommandBuffer.ParallelWriter ECB;
void Execute([ChunkIndexInQuery] int sortKey, in Health health, Entity entity)
{
if (health.Current <= 0)
ECB.DestroyEntity(sortKey, entity);
}
}
```
## Burst Compiler
The Burst compiler translates IL/.NET bytecode into highly optimized native code using LLVM.
### Usage
Add `[BurstCompile]` to `ISystem` structs (and each method) and `IJobEntity` structs. Burst compiles them to optimized native code via LLVM.
### Restrictions
- **No managed types** (no `class`, `string`, `List<T>`, managed arrays)
- **No allocations** (no `new` for reference types)
- **No try/catch/finally**
- **No virtuSkill source recorded
