#Spawn System

Create mesh entities at runtime and despawn them with automatic native cleanup.

#SpawnMeshEntity

World.SpawnMeshEntity() is a convenience method that creates an ECS entity, attaches a Transform and MeshComponent, and registers it with the native renderer in one call:

int bullet = world.SpawnMeshEntity(bulletMeshId, new Transform {
    X = spawnX, Y = spawnY, Z = spawnZ
});

This is equivalent to:

int entity = world.Spawn();
world.AddComponent(entity, transform);
world.AddComponent(entity, new MeshComponent {
    MeshId = meshId,
    RendererEntityId = NativeBridge.CreateEntity(meshId)
});

#Despawn with Auto-Cleanup

World.Despawn() automatically cleans up native renderer entities — no manual RemoveEntity call needed:

world.Despawn(entity);  // removes ECS entity + native renderer entity + cascade-deletes children

• If the entity has a MeshComponent, its RendererEntityId is passed to NativeBridge.RemoveEntity() before removal
• If the entity has children (via Hierarchy), they are recursively despawned as well
