As an expert in Pokémon games, I can guide you through the process of checking a Pokémon's happiness in Pokémon Diamond. Happiness is an important factor in Pokémon games, as it can affect certain aspects of gameplay, such as the likelihood of a Pokémon returning to the player after being traded or the potential for a Pokémon to gain Effort Values (EVs) in battle.

To check a Pokémon's happiness in Pokémon Diamond, follow these steps:


1. Open the Pokémon Summary: Select the Pokémon you want to check on your party list, and then choose "Summary" to view its details.


2. Look for the Hearts: In the summary screen, you will see a series of hearts next to the Pokémon's name. The number of hearts indicates the Pokémon's level of happiness. A full heart represents the highest level of happiness, while an empty heart means the Pokémon is not happy at all.


3. Consider Friendship-Boosting Items: If you want to increase your Pokémon's happiness, you can use items like Soothe Bell or Pecha Berry, which can boost friendship and happiness when used in battle.


4. Affecting Happiness through Actions: Certain actions can also affect happiness, such as walking with your Pokémon in the overworld as your first party member, using luxury Poké Balls, or feeding it berries.


5. Be Mindful of Negative Actions: Conversely, actions like using certain battle items or leaving your Pokémon in the PC storage for too long can decrease happiness.

Remember, a Pokémon's happiness is not just a number; it's a reflection of your bond with the Pokémon and can influence its performance and growth.
