ECS Command Buffer

ECS Command Buffer

CommandBuffer batches world mutations for deferred application.

Buffered Operations

• spawn entity (with initial components)
• destroy entity
• add component
• remove component

Usage

const commands = world.commands()
commands.spawn().with(Position, { x: 1, y: 2 })
commands.flush()

Deferred Entity Resolution

Spawn operations create deferred entities that resolve to real EntityId during flush().

Why Use It

• avoids mutable-iteration hazards during system execution
• centralizes write timing
• aligns with stage-level flush in scheduler
