- Moved the rig scene from `res://master_rig.tscn` to `res://scenes/stickman_rig.tscn`, preserving its UID.
- Split the `StickmanRig` controller into three components: `StickmanLocomotion`, `StickmanRagdoll`, and `StickmanActionRunner`.
- Updated the architecture to ensure `StickmanRig` acts as the public facade for the new components.
- Created a new test suite `test_phase8_rig_modularization.gd` to verify the integrity of the relocated rig and its components.
- Added checks for scene loading, component resolution, action queue delegation, and state authority.
- Introduced StageGizmos for hover highlighting, selection outlines, and rotation handles in the sandbox stage builder.
- Added StageGrid for an optional world-space grid overlay that adjusts with camera panning and zooming.
- Implemented StageSelection for geometric hit-testing and selection management of nodes in the sandbox.
- Created StageSpawner as a registry-driven factory for spawning terrain, props, and stickmen, allowing for dynamic template management.
- Each script includes necessary constants, state management, and public API methods for interaction.
- Added draggable handles for the torso and head to the test harness.
- Updated `IK_HANDLE_PATHS` to include new entries for "Head" and "Torso".
- Implemented distinct colors for the torso (magenta) and head (yellow) markers.
- Added a visual aid (aim line) to indicate the head's LookAt target direction.
- Ensured that dragging the torso moves only the torso marker, allowing for limb stretching towards stationary targets.
- Implement anisotropic scaling for shape mounting to prevent distortion.
- Replace bounding-box midpoint anchors with joint-based anchors for correct rotation.
- Reset node transforms to ensure clean scaling and rotation before mounting shapes.
- Introduce new helper functions for computing bounding boxes, anchors, part lengths, and scales.
- Neutralize driver rotations to maintain a consistent frame of reference during shape mounting.
- Update documentation to reflect changes and provide detailed bugfix specifications.
- Added StickmanFactory to load and instantiate .stk files into master_rig.tscn.
- Created a Test Harness scene for debugging bone scales, vector drawing offsets, and IK limits.
- Updated stk_rig_adapter to fit head bone and mount head shapes as full geometry.
- Enhanced README and PROJECT documentation to reflect new features and usage.
- Introduced UI elements for file selection and visual debugging in the Test Harness.
- Refactored code to improve clarity and maintainability, including removal of unused functions.
- Implemented StkRigAdapter class to adapt a master rig to a loaded .stk dictionary.
- Added methods for fitting bone lengths, recalibrating IK targets, and mounting vector shapes.
- Defined constants for default proportions and bone paths.
- Included error handling for missing nodes and invalid data structures.
