Developing a Character Selection System in Unity

Creating a character selection system for your Unity game can enhance the player experience and provide customization options. In this tutorial, we will learn how to implement a simple character selection screen in Unity and save the selected character for a new level.

Setting Up the Character Selection Screen

Game Objects: Begin by setting up a character selection screen with a character's game object containing child game objects as player prefabs to showcase the available character options.
UI Buttons: Add UI buttons (next, previous, start game) on a canvas that reference the character selection script to enable players to navigate through character choices and start the game.

Understanding the Script Logic

In the character selection script:

Variables: The script includes a characters array referencing all character prefabs and an index variable (selected character) to track the current selection.
Next Character Method: This method cycles through characters by deactivating the current selection, incrementing the index, and ensuring the index stays within bounds to create a looping effect.
Previous Character Method: Similar to the next character method but in reverse, ensuring seamless navigation between character options.
Start Game Method: Triggered by the start game button, this method utilizes player prefs to save the selected character index for use in the next scene.

Loading the Selected Character in a New Level

Load Character Script: In the game scene, a load character script retrieves the saved character index using player prefs and instantiates the corresponding character prefab at the spawn point.
Displaying the Chosen Character: The script updates the label to reflect the selected character's name, providing a seamless transition to the new level with the chosen character.
