Certainly! Given the problem statement, here's a test case generator for the "Spaceship UAZ Advance" problem:

```python
import random

def tcgen():
    def random_coord():
        return random.randint(-100, 100), random.randint(-100, 100), random.randint(-100, 100)
    
    # Generate coordinates for the UAZ Advance spacecraft and the enemy
    uaz = random_coord()
    enemy = random_coord()
    
    # Ensure UAZ Advance spacecraft and enemy are not in the same position
    while uaz == enemy:
        enemy = random_coord()
    
    # Generate coordinates for the three vertices of the barrier
    barrier_v1 = random_coord()
    barrier_v2 = random_coord()
    barrier_v3 = random_coord()
    
    return uaz, enemy, barrier_v1, barrier_v2, barrier_v3

# Example usage
uaz, enemy, barrier_v1, barrier_v2, barrier_v3 = tcgen()

print("UAZ Advance spacecraft coordinates:", uaz)
print("Enemy spacecraft coordinates:", enemy)
print("Barrier vertex 1 coordinates:", barrier_v1)
print("Barrier vertex 2 coordinates:", barrier_v2)
print("Barrier vertex 3 coordinates:", barrier_v3)
```

This script generates random test cases for the "Spaceship UAZ Advance" problem by:
- Creating random coordinates for the UAZ Advance spacecraft and the enemy.
- Ensuring that the UAZ Advance spacecraft and the enemy are not in the same position.
- Generating random coordinates for the three vertices of the barrier.

You can run this script to generate multiple test cases for your problem. If you need the output in a specific format, you can modify the print statements accordingly.
