Science behind the game

The spaceship position is controlled by the following code in the game

pose = self.camera.poses[0]
# Get left hip and right hip positon
r_hip = pose.keypoints[8]
l_hip = pose.keypoints[11]
                
# and find center
center = (
    (l_hip[0] + r_hip[0]) // 2, 
    (l_hip[1] + r_hip[1]) // 2
          )

# Set position 
self.player.rect.x = center[0]

The following lines of code is used to spawn the bullets

# Bullet spawn gesture
# if right or left hand is above neck
neck = pose.keypoints[1]
# Get left and right wrist positions
r_wrist = pose.keypoints[4]
l_wrist = pose.keypoints[7]

if r_wrist[1] < neck[1] or l_wrist[1] < neck[1]:
  self.shoot = True
else:
  self.shoot = False
