For this lesson on how to create among us in Unity, I will teach you how to create another character customization menu for changing the player’s hat. This will be similar to our player’s color Customization menu only using sprites instead of colors.

Having character customization in your game allows the players to add personality to their avatar and allows the players to become more engaged with your game. It also opens you to the possibility of adding an in-app store to your game.

To create this system we will duplicate our color menu and then change the copy into a hat menu. You can use this sprite sheet as placeholder images.

Next, we will add some navigation tabs to switch between the color menu and the hat menu.

Finally, you will need to add a new sprite object to your player prefab which will be our hat holder. This object needs to be placed at the top of the player’s head.
