# Collect & Escape 3D
|
|
|
|
A small playable project using the real Faset C++ gameplay module and Box3D adapter. The exit arch is an original Blender asset included as a GLB bundle, source `.blend`, and reproducible Blender script. Importing the included bundle does not require Blender. Gameplay geometry and physics use built-in primitives.
|
|
|
|
## Play
|
|
|
|
Import the included Blender bundle once (repeat after clearing the project cache), then open the project from the repository root:
|
|
|
|
```bash
|
|
build/linux-debug/faset_editor --project examples/projects/collect-3d \
|
|
--command '{"name":"faset_import","arguments":{"path":"Assets/exit-arch/manifest.json"}}' --wait
|
|
```
|
|
|
|
You can also import `Assets/exit-arch/manifest.json` from the Editor's Assets panel before Play.
|
|
Open the Editor:
|
|
|
|
```bash
|
|
build/linux-debug/faset_editor --project examples/projects/collect-3d
|
|
```
|
|
|
|
Use **Play** to build this project's `Scripts/Gameplay.cpp` and start a separate Player. On Windows use your Windows build directory and `faset_editor.exe`. First complete the engine build setup in the User Manual.
|
|
|
|
For a direct Player build on Linux, from the repository root:
|
|
|
|
```bash
|
|
cmake -S . -B build/collect-3d -G Ninja \
|
|
-DCMAKE_BUILD_TYPE=Debug \
|
|
-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
|
|
-DFASET_GAMEPLAY_SOURCE_DIR="$PWD/examples/projects/collect-3d/Scripts"
|
|
cmake --build build/collect-3d --target faset_player faset_schema_exporter
|
|
build/collect-3d/faset_player --scene examples/projects/collect-3d/Scenes/main.scene.json \
|
|
--assets examples/projects/collect-3d/.faset/cache
|
|
```
|
|
|
|
On Windows use a Developer shell with `clang-cl` and the Windows SDK, select `clang-cl` for both compiler options, and give `FASET_GAMEPLAY_SOURCE_DIR` an absolute path.
|
|
|
|
## Objective and controls
|
|
|
|
- WASD or arrow keys move on world X/Z. W points toward negative Z (away from the camera); diagonal speed is normalized.
|
|
- **Space** jumps while a native contact supports the player block.
|
|
- Collect all three **gold cubes**. Jump onto the raised platform for the middle pickup.
|
|
- Each pickup moves to the progress display. After all three, the **red physical gate** moves out of the level.
|
|
- Reach the **green exit** to reveal the large gold victory marker. Movement stops after completion.
|
|
- **E** restores the player, pickups, gate, and victory state. Falling below the level also resets the round.
|
|
- **P** pauses, **N** advances one fixed tick, and **Escape** closes the Player.
|
|
|
|
The Player window title and console identify the controls and objective; the game uses geometric progress markers rather than a text HUD. The player is a dynamic box with zero friction, not an articulated character controller. It can rotate after impacts.
|
|
|
|
## Inspect and change the game
|
|
|
|
`project.faset.json` chooses `Scenes/main.scene.json`. The scene stores object/component IDs, transforms, physics settings, and entity references in the collector component. `Scripts/Gameplay.cpp` owns the round's transient C++ state and registers its editable schema. `speed` and `jump_speed` use metres per second.
|
|
|
|
Edit the scene through the Inspector and restart Play to see new level data. Change C++ or its schema, then stop, build, and restart; C++ hot reload is not implemented. Runtime pickup progress does not rewrite the authoring scene or create Undo entries.
|
|
|
|
The project vendors `Scripts/Extensions/Beacon.hpp` from the engine's extension example. Its separate `example.beacon` schema and callback rotate the pickups and victory marker. This is a C++ header package explicitly registered by the game, not an Editor plugin or automatic reflection.
|
|
|
|
## Verify
|
|
|
|
The normal test build creates `faset_example_3d_tests`. It compiles this exact module, follows a route using movement/jump input, collects the elevated pickup, opens the gate, reaches the exit, resets the round, and restarts the scene. It does not teleport to pass the objective.
|
|
|
|
```bash
|
|
cmake --build build/linux-debug --target faset_example_3d_tests
|
|
ctest --test-dir build/linux-debug -R '^playable_3d$' --output-on-failure
|
|
```
|
|
|
|
The runtime test is independent of graphics. A Player run additionally requires the supported Vulkan platform setup. The Editor's Export action creates a separate Release build and a cooked standalone generation; run that generation's Player from its export directory.
|
|
|
|
## Recreate the Blender asset
|
|
|
|
With an unmodified Blender 4.5 or later and the engine repository as the current directory:
|
|
|
|
```bash
|
|
blender --background --factory-startup --python-exit-code 1 \
|
|
--python examples/projects/collect-3d/Assets/exit-arch/create.py -- "$PWD"
|
|
```
|
|
|
|
The script creates the three beveled stone pieces with persistent UUIDs, saves
|
|
`source.blend`, and publishes a checksum-verified GLB manifest. Reimport the manifest
|
|
after editing it. Placement and gameplay stay in the Faset scene. The arch is visual;
|
|
the separate red gate supplies the gameplay collision.
