Overview:

 Spatial Mini Games is a collection of engaging and interactive spatial experiences designed for Apple Vision Pro. Utilize the power of visionOS to immerse yourself in various fun and challenging mini-games that will test your reflexes and spatial awareness. Perfect for casual play, each game is quick and accessible, ideal for solo play or friendly fun at home gatherings.

Game Rules:

Eye Laser Blast: Look at glass bottles on walls and ceilings, then pinch your fingers to shoot lasers from your eyes and break them. Score points by breaking bottles within 1 minute. Pinch while looking to the right side of your field of vision to shoot a red laser, and pinch while looking to the left side of your field of vision to shoot a blue laser. Red bottles break with red lasers, blue bottles break with blue lasers, and green bottles break with either. Lasers reflect off real-world surfaces.

Finger Shooter: Move your thumb near your middle finger's second joint to shoot a ball from your index finger. Hit pumpkins to score points within 1 minute. Red balls come from the right hand, blue balls from the left. Red pumpkins need red balls, blue pumpkins need blue balls, and green pumpkins can be hit with either. Balls reflect off real-world surfaces.

Gaze Walker: Control a stick figure character with your gaze to collect coins while avoiding enemy robots. Utilize real-world objects for cover and hide behind them to evade enemies. Collect as many coins as possible within 1 minute.

Overall Features:

Interactive Environments: Balls and lasers interact with real-world surfaces, enhancing the immersive experience.

Use real-world objects strategically in Gaze Walker, hiding behind them to evade enemy robots.

Quick and Casual Play: Enjoy games that last just 1 minute, perfect for short play sessions.

Convenient Controls: Access menus anytime using the left-hand menu in each mini game to toggle music or return to the game selection screen.

Future Updates: New games and features will be added to keep the experience fresh and engaging.

Feature Details and Instructions

Safety Notice Confirmation: The initial safety notice is confirmed by gazing at and tapping three checkboxes.

Game Selection Screen:

• Tap on a bubble to display the game start button, game description, and up to the top 10 previous scores.
• Tap the config button to access the music toggle button and the reset game data button.

Game Start Transition:

• After selecting a game, a "Mini Games" panel is displayed, which changes to the Game Start button after 3 seconds.

Wall Scanning:

• The selected game begins with a scanned representation of the actual wall.
• It is recommended to look around and ensure the wall is correctly scanned.

Permission Request:

• Upon first use, the app will ask for permission to access hand movement and environmental data. You must select "Yes" to proceed with the game.
• If you accidentally select "No," go to settings, select the app, and allow access to "Hand Pose and Motion" and "Surroundings" for Spatial Mini Games.

In-Game Configuration:

• During any mini-game, tap the config button on your left wrist to display the music toggle button, home button, and remaining time.

UnityでつけたポーズをBlenderに取り込む方法（もっと簡単な方法あるかも）

Unityのエディタでシーンビュー内でつけたポーズをBlenderにもっていく方法
1. Unity側のスクリプトをポーズを付けたFBXにアタッチしてレストポーズにしたFBXを
referenceModelとして設定する。
ポーズを付けたFBXのrootBoneと出力先のパスを設定する。
2. インスペクター上で右クリックでExportBoneData
3. Blender側のスクリプトでアーマチュアの名前と読み込むポーズのファイルのパスを設定して RunScript

Formatting Animation Name Files for Use with ActionMaking.py

If the animation number files attached to your assets are not in the correct format for use with the ActionMaking.py script, please use the FormatAnimationNamesAnimColonNum.py script to adjust them.

This script performs the following tasks:

-Removes empty lines and trailing colons: This step cleans up unnecessary formatting that may interfere with processing.

-Replaces spaces with colons: This adjustment is made for lines where the frame range and animation name are separated by spaces instead of colons, ensuring consistency in data format.

-Checks and adjusts the position of name and frame data: This part verifies whether the line format is 'frames:name' or 'name:frames' and adjusts accordingly.

-Processes frame data: Depending on the number of listed frame ranges, the script selects the appropriate frames (the middle ones if there are four frames, the first two if there are three).

For example, a file with lines like:

50-80-110-140:WalkForward:

IdleToTrot:3850-3880-3910

will be changed to:

WalkForward:80-110

IdleToTrot:3850-3880

If there are any extraneous comments or notes that cannot be adjusted by this script, please remove them before running the script.
