Player controllers for 2D and 3D, plus the canonical third-person controller for Summer humanoid packages: movement owns translation, clips follow state.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Character Movement The player controller is the first thing you build and the thing the user feels in the first 3 seconds. Ship the smallest correct controller, then tune feel. Trigger phrases: "add player movement", "the player can't move / falls through the floor", "wire my imported character as the player", "walk/run/jump animations", "mouse look", "make the jump feel better". Supporting files live in this skill's `references/` folder, next to this SKILL.md. Open only the one the task needs: | File | Read when | |------|-----------| | `references/default-third-person-controller.gd` | standard playable third-person Summer humanoid package; copy this exact controller instead of rewriting it | | `references/default-third-person-verification-probe.gd` | runtime proof for that controller; pass it unchanged as a `RunVerification` `probe_source` | | `references/platformer-feel.md` | jump feels bad, coyote time, jump buffering, variable jump height, one-way platforms | | `references/movement-3d.md` | FPS/third-person controllers, mouse look, sprint, crouch, spring-arm camera | ## Default playable Summer character …

How to install
mdr add summerengine/summer/character-movement@sha256:9c5b1346c74b3bc8The line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
