Player Animation Core v0.0.0-beta.20 — Hand Position from Arm Rotation

Changes

• HANDS_ONLY_ARM now computes hand position from arm rotation angles (rotation.y for horizontal, rotation.x for vertical), reproducing the full swing arc in first person
• New configurable fields in FirstPersonConfiguration:
  • armLength (default: 8.0) — effective arm length in model units
  • pitchFactor (default: 0.6) — vertical movement multiplier
• Previously HANDS_ONLY_ARM only rotated the item in place; now the item also moves across the screen matching the third-person arm swing

Example

controller.setFirstPersonConfiguration(
    new FirstPersonConfiguration()
        .setArmRotationScale(1.0f)
        .setArmLength(8.0f)
        .setPitchFactor(0.6f)
        .setShowArmor(true));
