wave8-dynamic-buffer-invalidation

What problem does it solve?

Prevents undefined behavior, crashes, and silent corruption caused by reading a DynamicBuffer reference after a structural change invalidates its underlying memory pointer.

Core Features & Use Cases

• Frame- and structural-change-safe access: Treats DynamicBuffer references as only valid within the current structural-change context.
• Correct read-before-write ordering: Ensures buffer contents are read before performing operations like AddComponent, RemoveComponent, DestroyEntity, or CreateEntity.
• Safe structural change handling: Uses EntityCommandBuffer (ECB) to defer structural changes until after reads complete, or explicitly re-fetches the buffer after changes.

Quick Start

Use the DynamicBuffer invalidation guidance when you call GetBuffer<T> and later perform any structural change in the same system update, by reading buffer contents first (or deferring structural changes with ECB) and never using the old buffer reference afterward.
