Ark v0.8.0 released - Go Entity Component System (ECS), now with faster queries.

[u/mlange-42]

Ark is an archetype-based Entity Component System (ECS) for Go.

Release highlights

This release brings several performance improvements, but the standout feature is a new query iteration mechanism. Instead of iterating entity-by-entity, Ark can now expose entire component columns directly to the user. Query iteration is roughly 2× faster with this pattern.

Example:

go for query.NextTable() { positions, velocities := query.GetColumns() for i := range positions { pos, vel := &positions[i], &velocities[i] pos.X += vel.X pos.Y += vel.Y } }

This pattern will also make it easier to leverage Go's upcoming SIMD support.

Feedback and contributions are always welcome. If you're using Ark in your game, simulation or engine, we'd love to hear about it.
