Introduction

In this article, we will guide You through the process of creating your own game using Unity. We will cover various aspects such as finding art assets, setting up the game environment, implementing player movement and throwing mechanics, as well as creating a system for combining fruit when they are matched. By the end of this tutorial, you will have a complete game with functioning gameplay mechanics.

Finding Art for the Game

One of the challenges when making a game is finding suitable art assets. In this section, we will discuss different methods to find art that fits your game's theme. We will explore options like searching on websites like Canva, using ready-made sprites, and creating your own art elements for the level. We will also cover the concept of using a cat instead of a default character to add a personal touch to your game.

Setting Up the Background and Containment Box

To Create a visually appealing game, it is important to set up a suitable background and containment box for the gameplay area. In this section, we will guide you through the process of adding a background and a box to contain the fruit. We will also Show you how to separate the Outline and fill of the box by adding mild transparency, which enhances the overall look of the game.

Creating Colliders and Triggers

Colliders and triggers are essential components of any game, as they enable interactions between objects. In this section, we will show you how to set up colliders for the left, right, and bottom boundaries of the gameplay area. We will also demonstrate how to create a lose game trigger and a boundary trigger, which will be used to determine player movement and constrain it within the gameplay area.

Adding Score and Next Fruit Display

Having a scoring system in your game adds an element of challenge and motivation for the player. In this section, we will guide you through the process of adding a score Bubble to the game, which will display the player's Current score. We will also show you how to create a bubble to indicate the next fruit that will spawn in the game. Additionally, we will introduce a Chart to display the order of fruit evolution, enhancing the player's understanding of the game mechanics.

Setting Up Input for Player Movement and Throwing

To enable player control in the game, it is crucial to set up input for movement and throwing actions. In this section, we will discuss the process of installing and using the input system in Unity. We will guide you through setting up player input actions and creating a user input script that updates Based on the input actions. By the end of this section, you will have a functioning input system for the player.

Creating the Player Controller Script

The player controller script is responsible for handling the movement and throwing of the player character. In this section, we will guide you through the process of creating a player controller script. We will cover the variables needed for the script, as well as how to grab boundaries from the boundary trigger and constrain player movement within those boundaries. We will also show you how to create an aim line using a line renderer component.

Implementing Aim Line with Line Renderer

The aim line is a visual guide that helps the player determine where they are throwing the fruit. In this section, we will demonstrate how to implement the aim line using a line renderer component. We will guide you through the process of updating the Y position of the aim line based on player input and setting the line's points to follow the cat's position. Additionally, we will show you how to update the aim line's appearance in the Unity editor for better visualization.

Spawning and Throwing Fruit

Spawning and throwing fruit are fundamental gameplay mechanics in the game. In this section, we will guide you through the process of selecting and spawning the next fruit to be thrown. We will explain the concept of using two different arrays for spawning physics-based fruit and non-physics-based fruit. We will also show you how to create carbon copies of the fruit objects and update their properties accordingly. By the end of this section, you will have a functional system for spawning and throwing fruit in the game.

Combining Fruit When Matched

To add complexity and strategy to the game, we will implement a feature that allows players to combine matching fruit. In this section, we will guide you through the process of creating scripts for fruit information and fruit combining. We will demonstrate how to make fruit combine when they are touching and have the same index value. Additionally, we will show you how to handle combining watermelons, which will result in the cancellation of both fruits.

Updating Score and Game Over Condition

Updating the score and implementing a game over condition are crucial aspects of any game. In this section, we will show you how to keep track of the player's score using a game manager script. We will guide you through the process of displaying the score using a text mesh pro object and updating the score when fruit is combined. Additionally, we will demonstrate how to create a game over condition that triggers a fade-in effect, restarts the scene, and fades out the panel.

Conclusion

In this tutorial, we have covered the process of creating a game from start to finish. We explored various aspects such as finding art assets, setting up the game environment, implementing player movement and throwing mechanics, and creating a system for combining fruit when they are matched. By following this tutorial, you have learned valuable skills that can be applied to your future game development projects. We hope you enjoyed this tutorial and have fun experimenting with new game ideas!
