Are you ready to dive into the world of Pokémon battles in Python? With the poke-env library, you can create rule-based or reinforcement learning agents that can battle on Pokemon Showdown. This blog post will guide you through the installation and the basic setup of your very first agent!

Getting Started with Your First Agent

In the poke-env library, agents are instances of Python classes that inherit from the `Player` class. This allows you to define the behavior of your Pokémon agent during battles. Here is a simple analogy: think of your agent as a Pokémon Trainer, and the agent’s code as a set of commands that guide how the trainer chooses moves during a battle.

class YourFirstAgent(Player):
    def choose_move(self, battle):
        for move in battle.available_moves:
            if move.base_power > 90:
                # A powerful move! Let's use it
                return self.create_order(move)
        # No available move? Let's switch then!
        for switch in battle.available_switches:
            if switch.current_hp_fraction > battle.active_pokemon.current_hp_fraction:
                # This other Pokémon has more HP left... Let's switch it in?
                return self.create_order(switch)
        # Not sure what to do? 
        return self.choose_random_move(battle)

Understanding the Code: The Trainer’s Strategy

Imagine your Pokémon Trainer is facing an opponent. Here’s how the code reflects their strategy:

• Choosing a Move: The trainer looks at all available moves. If one has high base power (over 90), it’s like deciding to use a powerful attack because it will likely defeat the opponent.
• Switching Pokémon: If no strong move is available, the trainer assesses whether switching to another Pokémon (with more HP) is a better strategy, much like a trainer deciding to use a healthier Pokémon in a tough match.
• Random Move: If all else fails, the trainer picks a random move, akin to making a last-minute decision when uncertain about what action to take.

Installation: Setting Up Your Environment

To get started, you’ll need Python version 3.8 and a Pokémon Showdown server. Follow these steps to set everything up:

1. Install poke-env using pip:

pip install poke-env

2. Clone the Pokémon Showdown repository from Github:

git clone https://github.com/smogon/pokemon-showdown.git
cd pokemon-showdown
npm install
cp config/config-example.js config/config.js
node pokemon-showdown start --no-security

Troubleshooting Common Issues

Experiencing some hiccups in your setup? Here are a few troubleshooting tips:

• Command Not Found: Ensure that Python and npm are installed and added to your PATH.
• Network Issues: If you can’t connect to the Pokémon Showdown server, check your internet connection or try using a different network.
• Permission Errors: Running commands might require administrative access; try running your terminal as an administrator.
• Library Not Found: Make sure you have poke-env installed correctly via pip and that it doesn’t return an error.
