Final Answer:
To add the second enemy to the backdrop script, insert the following block of code after the section that initializes the first enemy:
```python
# Second Enemy
enemy2 = create_enemy(x_position, y_position)
enemies.append(enemy2)
```
Step-by-step explanation:
In the provided script, the addition of a second enemy involves creating a new enemy object (`enemy2`) and appending it to the list of enemies (`enemies`). The `create_enemy` function is assumed to handle the instantiation and initialization of enemy objects, using the specified `x_position` and `y_position` parameters. This block of code ensures that the second enemy is properly integrated into the game.
The `enemies` list likely serves as a container for all the enemy objects present in the game. By appending `enemy2` to this list, the game engine will recognize and manage the newly added enemy during gameplay.
It's crucial to place this block of code in the appropriate location within the backdrop script, specifically after the initialization of the first enemy. This ensures a sequential and organized flow of code execution. The exact positioning of the block may depend on the existing structure of the script, but generally, it should be inserted where the game initializes and sets up its entities.
