So You Want to Make a Game? (Using Unity, Unreal, or Godot)
Hey there, future game dev genius! š Ever had that moment where you're playing a game and think, "I could totally make this!"? Well, good news ā you can! And guess what? Itās easier than you think. Today, we're diving into the basics of game development using Unity, Unreal Engine, and Godot, three of the coolest kids in the game dev block.
Letās break ā like explaining game development to your grandma, except, you know, with code. And fewer cookies.
1. Whatās a Game Engine? (No, Itās Not a Car Engine)
A game engine is like the magical kitchen where all the ingredients for a game come together. Youāve got your graphics, your physics (gravity exists in games too, sadly), your scripting (fancy term for coding), and your animations (you know, how your character doesnāt walk like a robot).
Imagine you're making a pizza. The game engine is the oven. It bakes everything perfectly so you can deliver a delicious gameā¦err, pizza. š Same thing!
2. The Big Three: Unity, Unreal, and Godot (Like a Superhero Team, But for Games)
Unity
- Best for: Newbies, indie creators, and people who donāt want their computer to explode from high system requirements.
- Code Talk: C# (sounds intimidating, but itās pretty chill).
- Where It Works: PCs, phones, consoles, the toaster in your kitchen (okay, maybe not that last one).
Unity is like your super-friendly cousin whoās great at everything: 2D games, 3D games, you name it. Plus, thereās an asset store, where you can grab free or paid goodies like characters and explosions without breaking a sweat.
Unreal Engine
- Best for: Those who love shiny, realistic graphics and epic scenery. You want to make the next Avengers? Unrealās your buddy.
- Code Talk: C++ (for hardcore coders) and Blueprints (for lazy coders ā I mean, for visual thinkers).
- Where It Works: Same as Unity, but itās the boss when it comes to blockbuster games and VR.
Unrealās the flashy friend who shows up in a Ferrari. Itās got all the tools for high-end, jaw-dropping games, but donāt worry ā itās got an easy mode too, called Blueprints, where you can drag and drop your way to success. No coding? No problem! šØ
Godot
- Best for: Open-source enthusiasts (a.k.a. fans of free stuff) and people who dig simplicity.
- Code Talk: GDScript (Pythonās chill younger sibling), C#, and even VisualScript for the visual peeps.
- Where It Works: Same as Unity and Unreal, but with less fanfare and more hipster vibe.
Godot is like the artsy friend who listens to indie music before itās cool. Itās lightweight, free, and awesome for making 2D games. But donāt count it out for 3D stuff either ā itās just more of a minimalist approach.
3. Time to Build a Game: "Catch the Falling Donuts!" š©
Weāre going to build a ridiculously simple game across all three engines: Catch the Falling Donuts. Because, letās face it, no one wants to let donuts hit the ground.
Unity: Catching Donuts with Style
Step 1: Set Up Your Game
- Open Unity, create a new 2D project, and boom! Blank canvas. šØ
- Add a square (your player) and another square (your donut, letās use some imagination here).
Step 2: Make the Player Move
- Hereās a super simple C# script to move your player left and right. Think of it like pushing a shopping cart down the aisle ā youāre avoiding all those pesky kidsā toys to get to the donuts.
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public float moveSpeed = 5f;
void Update()
{
float move = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;
transform.Translate(move, 0, 0);
}
}
Stick this on your player, and now you can zip left and right with the arrow keys like a pro donut catcher. š©šØ
Step 3: Make Donuts Fall from the Sky
- Add this code to your donut, and watch them rain down from donut heaven:
using UnityEngine;
public class FallingDonut : MonoBehaviour
{
public float fallSpeed = 3f;
void Update()
{
transform.Translate(0, -fallSpeed * Time.deltaTime, 0);
if (transform.position.y < -5f)
{
transform.position = new Vector2(Random.Range(-8f, 8f), 5f);
}
}
}
The donuts fall, you move, you catch. Itās like real life, but with more carbs.
Unreal Engine: Donuts in HD
Step 1: Open Unreal Engine
- Start a 2D project, and add a Sprite for your player and donut (you can find a donut image later, but squares work too).
Step 2: Add Blueprint Magic
Hereās where Unrealās Blueprints make you feel like a wizard. š§āāļø
- In the Blueprint Editor, drag out a node for Input Axis and connect it to Add Movement Input. Boom, instant movement with no typing involved. š©āØ
Step 3: Make Donuts Drop Like Itās Hot
- Use another Blueprint to make your donuts fall. Unrealās Blueprints work like LEGO blocks, so you just snap the pieces together and feel like a genius.
Godot: Donuts in a Hipster Paradise
Step 1: Set Up the Scene
- Open Godot, create a new 2D project, and toss in some Sprite nodes for your player and donut.
Step 2: Player Moves (Python-Style)
This is GDScript ā think of it as Python but way more game-friendly.
extends Sprite
var speed = 200
func _process(delta):
var direction = 0
if Input.is_action_pressed("ui_left"):
direction -= 1
if Input.is_action_pressed("ui_right"):
direction += 1
position.x += direction * speed * delta
Your player now moves like itās rushing for the last donut in the box.
Step 3: Donut Rain, Activate
Hereās a simple script to make those donuts fall and reset when they hit the ground:
extends Sprite
var fall_speed = 150
func _process(delta):
position.y += fall_speed * delta
if position.y > 600:
position.y = 0
position.x = rand_range(0, 1024)
Now donuts fall, and your job is to catch them all! š© Think of it as the PokĆ©mon of the pastry world.
4. Key Ingredients of Every Game (a.k.a. Stuff You Canāt Forget)
1. Assets
- Your game's assets are like toppings on a pizza. Sprites, sounds, music ā all the fun stuff. Grab them from Unityās Asset Store, Unrealās Marketplace, or Godotās Library.
2. Physics
- Every game engine has built-in physics, so objects know how to behave. Itās like gravity telling you, "Yes, that donut will fall!" š©ā¬
3. User Input
- Games react to what you do. Whether youāre mashing buttons on a controller or tapping a screen like it owes you money, input makes your character move, jump, and catch those delicious donuts.
5. Final Thoughts (and Donut Rewards)
Congratulations! š You now have a basic understanding of how to make a game in Unity, Unreal, or Godot. Whether youāre moving boxes or catching donuts, these tools make game development accessible, fun, and surprisingly easy.
So, grab your engine of choice, start small, and work your way up to making the next big hit! And remember: catching donuts is just step one. Soon, youāll be creating galaxies, epic battles, or the next virtual cooking simulator. Who knows? Just donāt forget to have fun! š©š¾
Happy game making! š®
