No more chainable APIs?

I am in the process of upgrading my project to a newer version of Entitas and I noticed that 0.37.0 is generating void for the component methods, which means I can no longer chain Entity creation, ie, something like below no longer works;

context.ReplaceMoveInput(movement).IsDeleteOnExit(true);

Or for a specific entity,

e.AddTurnBased(i + 1, config.turnDelay)
 .IsAIMove(true)
 .AddFoodDamager(dmg)
 .AddSmoothMove(config.turnDelay)
 .AddAudioAttackSource(Audio.scavengers_enemy1, Audio.scavengers_enemy2);

Is there a replacement or new best practice for this functionality? Having a fluent style API was really nice for quickly setting up entities.

Hey @JamesMcMahon,

sorry for removing this, but the good thing is, if you’re preferring a different output from the code generator you can easily customize this by adding and using a custom generator.

All current generators can be found here: https://github.com/sschmid/Entitas-CSharp/tree/develop/Addons/Entitas.CodeGeneration.Plugins/Entitas.CodeGeneration.Plugins/Plugins/CodeGenerators

You can create a new class and get inspired (aka copy paste) by existing generators. Put all your custom generators into an Editor folder and you will be able to select them in the Entitas Prefs Window.

You could for example change the ComponentEntityGenerator and create a custom one that return the entity.

https://github.com/sschmid/Entitas-CSharp/blob/develop/Addons/Entitas.CodeGeneration.Plugins/Entitas.CodeGeneration.Plugins/Plugins/CodeGenerators/ComponentEntityGenerator.cs#L20-L43

    public ${ContextName}Entity Add${ComponentName}(${memberArgs}) {
        var index = ${Index};
        var component = CreateComponent<${ComponentType}>(index);
${memberAssignment}
        AddComponent(index, component);

        return this;
    }

Hope that helps
