1.1.1

Features & Changes

• The World can now be modified during queries using world.Create, world.Destroy, world.Set, world.Add, world.Remove.
• Queries and Enumerators now iterate backwards over the entities.
• A new CommandBuffer-API is available which combines the previous ones.
• QueryDescription now features a new API to reduce boilerplate : var desc = new QueryDescription().WithAll<Position, Velocity>....
• Added Arch.Samples which provides a small usage sample with Arch and Monogame :)
• Several small bug fixes and tweaks.

CommandBuffer

You no longer need several CommandBuffers, but a single one. The syntax is now much simpler.

var entity = world.Create<Transform, Rotation, int>();
var bufferedEntity = commandBuffer.Create(new ComponentType[] {typeof(Transform), typeof(Rotation), typeof(int) });  // Later also generic overloads to get rid of arrays. 
        
commandBuffer.Set(in entity, new Transform{ X = 20, Y = 20});
commandBuffer.Add(in entity, new Ai());
        
commandBuffer.Set(in bufferedEntity, new Transform{ X = 20, Y = 20});
commandBuffer.Add(in bufferedEntity, new Ai());

commandBuffer.Playback();
