# SimVerse / cutrope

Cut the Rope video-to-command: watch a short gameplay video of one Cut the Rope level (with a coordinate grid overlay) and output a deterministic command script that, replayed from the same initial state, wins the level.

- **Records:** 272 levels
- **Modality:** short MP4 gameplay video (~3s each, 1920×1080)
- **Output:** `{"commands": "...", "reason": "...", "confidence": 0..1}` (open-ended; many winning scripts may be valid)

## Loading

```python
from datasets import load_dataset

ds = load_dataset("SimVer-ano/simverse2026", "cutrope")
example = ds["test"][0]

system_text = example["prompt"]["system"]
user_text   = example["prompt"]["user"]

video_path = example["video_relative_to_config"]["path"]   # e.g. "videos/rope-000.mp4"
mime_type  = example["video_relative_to_config"]["mime_type"]

gold_commands = example["answer"]["commands"]              # one known-3-star reference script
```

## Schema

| Field | Type | Description |
|---|---|---|
| `level_id` | string | Level id, e.g. `"rope-000"` |
| `__sample_id__` | string | Same as `level_id` |
| `prompt.system` / `prompt.user` | string | Exact prompt text |
| `video.path` | string | Original (project-relative) video path |
| `video.mime_type` | string | Always `"video/mp4"` for shipped variants |
| `video.duration_seconds` | int | Video length |
| `video.fps` | int | Frame rate |
| `prompt_level.canvas_width / canvas_height` | int | Game canvas dimensions |
| `prompt_level.object_counts` | dict | Per-object-type counts: `target`, `candy`, `star`, `bubble`, `pump`, `gravity_button`, `grab_or_rope_anchor`, `left_candy`, `right_candy` |
| `prompt_level.two_parts` | bool | Whether the level starts with split-candy halves |
| `level_json_without_solution` | dict | The full level definition stripped of the gold solution; useful if you want to recreate the simulation state without seeing the answer |
| `video_relative_to_config` | dict | `path` / `mime_type` rewritten to be relative to this config's root |
| `answer.commands` | string | Reference winning command script (one command per line) |
| `answer.reason` | string | Short explanation of the reference solution |
| `answer.confidence` | float | Always `1.0` for the shipped reference |
| `legacy_answer` | string | Same script under the pre-v1 field name `reference_solution` (kept for back-compat) |

## Command DSL

Commands accept these actions, optionally guarded by `when <CONDITION>`:

```
cut_rope N | cut_rope N,M,K       # cut one or more ropes
pop_bubble N | pop_bubble_left | pop_bubble_right
activate_pump N [times C] [every S] [until <CONDITION>]
move_grab N X | move_grab N X Y
kick_rope N
toggle_gravity
```

Conditions include `candy_x`/`candy_y` thresholds, `candy_near X,Y,R [for S]`, `candy_still for S`, `rope_cut N`, `no_rope`, `candy_in_bubble`, plus split-candy variants `left_candy_*` / `right_candy_*`. Boolean combinators `and` / `or` and parentheses are supported. `wait_frames` is **not** allowed in this benchmark version — use condition-based waits.

See the system + user prompt embedded in each record for the full vocabulary.
