v0.5.0

rocco v0.5.0

This release brings three milestones: the 3D Scene as a tree, gamepads, and skinned meshes with Clips.

This release breaks the Vocabulary three times. Every game must change its code.

• The 3D tree. Scene.nodes : List(Node) replaces draws, lights and colliders. A Node is a Group, Draw, Light or Collider, and a Group's children are placed relative to it. A Collider turns by rot, a Quat, in place of yaw.

• Gamepads. Input gains gamepads : List(Gamepad). pf.Button names the buttons by their place on the pad. A test that writes an Input record must add gamepads: [], or start from Input.empty.

• Skinned meshes. A .glb with one Skin of at most 64 Joints loads with its Clips. Each Manifest entry gains clips, and a Draw gains pose. Start a Draw from Draw.default to get a Pose of all zeros. Mesh.clip finds a Clip id by name, and the new Pose module builds and loops a Pose.

• Decisions: ADR 0014, The 3D Scene crosses the seam as a tree, ADR 0015, Gamepads are polled in the host, ADR 0016, Skinned meshes are posed in the host

• Guides: guide/scene.md, guide/gamepad.md, guide/assets.md, tutorial chapter 9 and tutorial chapter 10

Built with the Roc nightly nightly-2026-10-11-7d256b9. Use the same nightly to run an app on these bundles.
