  • Collectible
  • Button
  • Background
  • Light

Components add functionality to GameObjects.

Common components include:

  • Transform
  • Rigidbody
  • Collider
  • Sprite Renderer
  • Mesh Renderer
  • Animator
  • Audio Source
  • Custom C# scripts

For example, a player GameObject may include a Transform, Rigidbody, Collider, Animator, and movement script.


Create Player Controls

Player controls translate input into action.

For Android games, input may include:

  • Screen taps
  • Swipe gestures
  • Virtual buttons
  • Accelerometer input
  • Dragging
  • Touch position

A simple C# script may move a player:

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    [SerializeField] private float speed = 5f;

    private void Update()
    {
        float horizontal = Input.GetAxis("Horizontal");

        transform.Translate(
            Vector3.right * horizontal * speed * Time.deltaTime
        );
    }
}

Mobile projects may replace keyboard input with touch controls.


Use Physics and Collisions

Unity physics can simulate:

  • Gravity
  • Movement
  • Impact
  • Bouncing
  • Friction
  • Collision
  • Forces

A Rigidbody allows an object to participate in physics.

A Collider defines the area used for collision detection.

Collision scripts can trigger:

  • Game over
  • Score changes
  • Item collection
  • Sound effects
  • Animations
  • Object destruction

Create Camera-Follow Systems

The camera should keep important gameplay visible.

A camera-follow script can track the player while maintaining a fixed distance.

using UnityEngine;

public class CameraFollow : MonoBehaviour
{
    [SerializeField] private Transform target;
    [SerializeField] private Vector3 offset;

    private void LateUpdate()
    {
        transform.position = target.position + offset;
    }
}

Smooth camera behavior improves readability and player comfort.

  • Premium downloads
  • Subscriptions
  • Cosmetic items

The specialization focuses on video-ad integration.

Interstitial Ads

Interstitial ads appear between gameplay moments, such as:

  • After a level
  • After game over
  • Between sessions
  • Before returning to the menu

They should not interrupt important player actions.

Rewarded Video Ads

Rewarded videos give players an optional benefit for watching an advertisement.

Rewards may include:

  • Extra life
  • Bonus coins
  • Power-up
  • Continue option
  • Additional level access

Rewarded ads should clearly explain what the player will receive.


Build Ethical Monetization

Monetization should not damage the player experience.

Good practices include:

  • Avoiding excessive interruptions
  • Making rewarded ads optional
  • Clearly explaining rewards
  • Protecting younger users
  • Following app-store policies
  • Respecting privacy requirements
  • Testing ad placement carefully

A sustainable game should balance business goals with player satisfaction.


Use Version Control

Version control tracks changes to your game project.

Git can help you:

  • Save project history
  • Restore previous versions
  • Create branches
  • Test new features safely
  • Collaborate with developers
  • Review changes
  • Protect work from accidental loss

GitHub and Bitbucket provide online repository hosting.

A useful Unity .gitignore file should exclude generated folders such as:

  • Library

A simple score manager might look like this:

using UnityEngine;
using TMPro;

public class ScoreManager : MonoBehaviour
{
    [SerializeField] private TMP_Text scoreText;

    private int score;

    public void AddScore(int amount)
    {
        score += amount;
        scoreText.text = $"Score: {score}";
    }
}

Separating responsibilities into different scripts can make the project easier to maintain.


Use Game-State Management

A game may move through several states:

  • Main menu
  • Playing
  • Paused
  • Game over
  • Level complete
  • Loading

A central game manager can control these transitions.

This helps coordinate:

  • Time scale
  • UI screens
  • Player input
  • Score
  • Level loading
  • Restart behavior

Create Achievement Systems

Achievements reward players for completing specific goals.

Examples include:
