Programming questions

1. Design game scenes
   1. The red capsule is the player （ The camera object is under the player object , Place the camera over the player's head ）
   2. Automatic doors with blue and yellow doors
   3. pos01、pos02 Is the clone location

1. Design game strategies
   1. Use the horizontal and vertical keys on the keyboard （WSAD） Control player movement
   2. Press down B key , The blue automatic door disappears ,10 Seconds later, the automatic door is displayed again
   3. Game begins 3 Seconds later in position pos1 Random cloning around 3 A black cube ,5 Seconds later in position pos2 Random cloning around 5 A black cube （ Application process ）
   4. When the player moves near the first batch of black cubes , Left click , Fire red bullets from the player's head , When the bullet hits the black cube , The black cube disappears , If it doesn't work, hit , Red Bullet 5 Seconds later, it will disappear
   5. When the player moves near the second batch of black cubes , Press once F Key to make a black cube disappear
   6. When the player moves to the Yellow automatic door , Press down Y key , The Yellow automatic door moves upward 8 rice ,10 Seconds later, it falls back to its original position
   7. When the player returns to the starting point , When you hit an air wall , The game appears 5 Second countdown
   8. Time is over. , The game end dialog box pops up , Click on “ restart ” Button , The game can start again

I suggest you do it yourself first   

The method doesn't have to be exactly like this   Reference only “ His writing ”  There's no big problem ！
