Possible Reasons You Can't Attack:
* Incorrect Menu Selection: Are you accidentally selecting "Run" or "Items" instead of "Fight"?
* Status Conditions: Your Pokemon might be affected by a status condition like "Paralyzed" or "Frozen" which prevents them from attacking.
* Opponent's Turn: Is it your opponent's turn to attack? If the battle animation hasn't finished, you can't act.
* Game Glitch: Occasionally, glitches can occur in older games.
Troubleshooting Steps:
1. Double Check Menu Selection: Make absolutely sure you're selecting the "Fight" option when you want to attack.
2. Check for Status Conditions: Inspect your Pokemon for status conditions like "Paralyzed," "Frozen," or "Confused." If they are afflicted, you'll need to find a way to cure them (like using an item or a move).
3. Wait for Your Turn: Be patient and let the battle animation play out completely. It's possible you just haven't reached your turn yet.
4. Try Saving and Reloading: Sometimes, saving your game and then reloading can resolve glitches.
5. Verify Game Cartridge: Ensure your game cartridge is clean and free of dust or debris.
6. Reset Your Console: If all else fails, try turning your console off and back on.
If Nothing Works:
If you've tried all these steps and are still unable to attack, there might be a more persistent bug. Consider:
* Resetting the Game: This will erase all your progress, but it could be necessary to fix the bug.
* Searching Online: Try searching online for "Pokemon Black can't attack bug" or a similar query. Other players may have experienced this and found solutions.
