Reactivity

sbox-reactivity A reactivity system for s&box. It makes writing code that runs in response to state changes easy. Check out https://github.com/impulsh/sbox-reactivity for documentation. public class MyComponent : ReactiveComponent { [Property, Reactive] public float Speed { get; set; } = 50f; [Reactive, Derived(nameof(_tintColor))] public Color TintColor { get; } = Color.Blue; private Color _tintColor() { // Calculate the tint color only when the speed changes return Math.Abs(Speed) <= 100f ? Color.Blue : Color.Red; } protected override void OnActivate() { Effect(() => { // Create a game object when this component is enabled var go = new GameObject(); var model = go.AddComponent<ModelRenderer>(); model.Model = Model.Cube; // Tint the model whenever it changes Effect(() => model.Tint = TintColor); // Spin the object every frame while the component is enabled Frame(() => { var angles = go.LocalRotation.Angles(); angles.yaw += Speed * Time.Delta; go.LocalRotation = angles; }); // Destroy the object when the component is disabled return () => go.Destroy(); }); } }
