Game Idea: Color Bounce

Color Bounce is a hybrid casual game that combines elements of endless runner and color-matching games. The player controls a bouncing ball that changes color and must avoid obstacles and collect color-matching gems to gain points. The game gets progressively difficult as the player advances.

Step-by-Step Development Guide

1. Create a new Unity project
   Start by creating a new 2D Unity project. Set the project name, location, and select 2D mode.

2. Set up the game scene
   In the default scene, delete the default main camera and create a new 2D Orthogonal camera. Set the camera size to 5.

3. Create the player character

   • Import a simple ball sprite or create one using the built-in Unity tools.
   • Create a new GameObject and attach the ball sprite to it.
   • Add a CircleCollider2D and Rigidbody2D components to the ball GameObject.

4. Create the PlayerController script

   • Create a new C# script called "PlayerController" and attach it to the ball GameObject.
   • Open the script in your preferred code editor and add the following code:

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float jumpForce = 10f;
    public Color[] colors;

    private Rigidbody2D rb;
    private SpriteRenderer spriteRenderer;
    private int currentColorIndex;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        spriteRenderer = GetComponent<SpriteRenderer>();
        ChangeColor();
    }

    void Update()
    {
        if (Input.GetButtonDown("Jump") || Input.GetMouseButtonDown(0))
        {
            rb.velocity = Vector2.up * jumpForce;
        }
    }

    void ChangeColor()
    {
        currentColorIndex = Random.Range(0, colors.Length);
        spriteRenderer.color = colors[currentColorIndex];
    }

    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("ColorChanger"))
        {
            ChangeColor();
            Destroy(other.gameObject);
            return;
        }

        if (other.CompareTag("Gem"))
        {
            if (other.GetComponent<SpriteRenderer>().color != colors[currentColorIndex])
            {
                Debug.Log("GAME OVER");
                // Implement game over logic here
            }
            else
            {
                Debug.Log("GEM COLLECTED");
                // Implement point increment and gem destruction here
            }
        }
    }
}

5. Create the obstacle and gem prefabs

   • Create GameObjects for the obstacles and gems.
   • Attach the appropriate sprites and set up colliders (e.g., BoxCollider2D for obstacles, CircleCollider2D for gems).
   • Create prefabs for the obstacles and gems.

6. Set up the color changer

   • Create a color changer GameObject with a custom sprite or a simple shape.
   • Add a BoxCollider2D and set it to be a trigger.
   • Add a "ColorChanger" tag to the GameObject and apply the tag.

7. Create the LevelSpawner script

   • Create a new C# script called "LevelSpawner" and attach it to an empty GameObject in the scene.
   • Open the script in your preferred code editor and add the following code:

using UnityEngine;

public class LevelSpawner : MonoBehaviour
{
    public GameObject obstaclePrefab;
    public GameObject gemPrefab;
    public GameObject colorChangerPrefab;
    public float spawnInterval = 2f;

    private float timeToSpawn;

    void Update()
    {
        if (Time.time >= timeToSpawn)
        {
            SpawnObstacles();
            timeToSpawn = Time.time + spawnInterval;
        }
    }

    void SpawnObstacles()
    {
        // Instantiate obstacles, gems, and color changers with random positions and colors
    }
}

8. Implement the SpawnObstacles method

   • In the LevelSpawner script, implement the SpawnObstacles method to instantiate obstacles, gems, and color changers with randomized positions and colors.

9. Create a GameManager script

   • Create a GameManager script to handle game states, player score, and UI updates.
   • Implement methods to start the game, end the game, and restart the game.

10. Design the UI

    • Create UI elements for the score display, game over screen, and restart button. Link the UI elements to the GameManager script.

11. Test and polish the game

    • Test the game and adjust variables like spawn rates, jump force, and obstacle speeds to achieve the desired level of difficulty and fun.

Once you have implemented all the steps, you will have a unique hybrid casual game, Color Bounce. You can add more features, such as power-ups, different types of obstacles, or a global leaderboard, to further enhance the game.
