Complete C# Unity Game Developer 2D

If you're experiencing issues with intelliSense not working, this guide will walk you through several steps to hopefully get things working.

In this video (objectives)…

1. For those new to Unity we'll take a quick tour around the interface and create a fun little pretend platformer scene.

In this video (objectives)…

1. We need tell Unity to use our preferred code editor and for those of us using VS Code, we'll be adding the required extensions. We'll write our first code using Debug.Log() to print to the console.

In this video (objectives)…

1. Lucy invites you to join us in our various community support forums in order to ask questions, connect with other students and share your progress.

In this video (objectives)…

1. Any time we change our project during a lecture we will commit that change to a public source control repository for students to access. In this video we show you how to access that content.

In this video (objectives)…

1. We overview what we'll be covering in this section of the course.

In this video (objectives)…

1. Let's look at the specific game mechanics and design we'll be implementing for this game.

In this video (objectives)…

1. In this lecture we introduce methods and take some time to understand the difference between the Start() and Update() callbacks.

In this video (objectives)…

1. In addition to rotating our object we want to move it forwards. We'll do this by using Tranform.Translate().

In this video (objectives)…

1. Variables are a critical aspect to any code so in this lecture we'll discuss how to use variables and specifically how to type them in C#.

In this video (objectives)…

1. To make our game easier to tweak and tune we can add SerializeField as an attribute to make our variables visible in the Unity Inspector.

In this video (objectives)…

1. Its time to make our vehicle respond to player input. We'll quickly set up the inputs using the "old" input system.

In this video (objectives)…

1. Currently our game will work differently on everyone's computer because its not framerate independent. We use Time.deltaTime to make our car drive in the same manner on all computers.

In this video (objectives)…

1. To change our game from basic images moving around to objects which can bump into each other we need to understand Colliders and Rigid Bodies.

In this video (objectives)…

1. When we bump into things we can make other things happen in our code using OnCollisionEnter2D().

In this video (objectives)…

1. If we want to make things happen in our game when we pass through an area or through another object we can use OnTriggerEnter2D().

In this video (objectives)…

1. We bring in some simple car game images into our game and play around with the pixels per unit settings to make sure our objects are the right size.

In this video (objectives)…

1. Let's make our level a bit more interesting by creating a simple level layout using our assets.

In this video (objectives)…

1. In this lecture we create a simple follow camera by telling the camera to use the same position as the player's car. We also need to add an offset so that camera is not right on top of the car by creating a new Vector3 value.

In this video (objectives)…

1. We need a way of doing something only if we collide with our package trigger and only if we collide with our customer trigger. The tools we'll be using will be if statements and tags and also take a first look at the == operator.

In this video (objectives)…

1. Bools are very helpful, especially when combined with if statements. We create our first bools to make sure we can only deliver a package if we've first picked on up.

In this video (objectives)…

1. After we pick up a package we want it to disappear, so we're going to use the Destroy() method to remove our package game objects after we've collided with them.

In this video (objectives)…

1. To give the player feedback regarding whether they have the package or not we'll change the color of our vehicle by modifying the Sprite Renderer component. To do this we'll learn how to use GetComponent.

In this video (objectives)…

1. In this lecture we wrap up our functionality by adding a boost pad we can drive over and a condition where bumping into obstacles will slow the vehicle.

In this video (objectives)…

1. We're done with this section - we've created a fun little driving game and learned some of the fundamentals of C# programming.

In this video (objectives)…

1. In this section we'll be using sprite shapes, effectors, particle effects and more.

In this video (objectives)…

1. Its good to start with the design and technical requirements for a project and that is precisely what we'll do in this lecture.

In this video (objectives)…

1. To create a free-flowing organic level in our game we can use Unity Sprite Shapes. In this lecture we create a Closed Sprite Shape and Sprite Shape profile as well as import a basic set of assets we can use in our project.

In this video (objectives)…

1. Edge Colliders are intended to follow a shape exactly which makes them the perfect way for us to keep objects on our track.

In this video (objectives)…

1. Cinemachine is a powerful package that allows us to create virtual cameras. In this lecture we'll create a follow camera using Cinemachine.

In this video (objectives)…

1. Instead of a ball rolling around we want a snow boarder to be sliding around our level, so in this lecture we'll set our 'Barry' our brave snow boarder.

In this video (objectives)…

1. Surface Effectors act like a conveyor belt and are a quick an easy way to move our character along the path.

In this video (objectives)…

1. We can spin our character in a few different ways, but the best is going to be by using the AddTorque() method to apply rotational force to the game object.

In this video (objectives)…

1. We need a win condition and lose condition so in this lecture we'll create a finish line and crash detection.

In this video (objectives)…

1. To restart the game we'll use SceneManager.LoadScene(). To access this we need to use the SceneManagement name space, so we'll be discussing how namespaces work.

In this video (objectives)…

1. Our level loads immediately upon the collision event, however we want a short delay. To do that we'll use Invoke().

In this video (objectives)…

1. Particle systems can add a lot of polish to our game, so we're going to experiment with creating a couple of cool particle effects.

In this video (objectives)…

1. We'll add code to our scripts so that we can play our particle effects at the right time.

In this video (objectives)…

1. It's time to tweak our game to make it more playable and look a bit better.

In this video (objectives)…

1. FindObjetOfType is another approach we can use to set a reference to a component or object.

In this video (objectives)…

1. We add some dust particles to our snow board and turn them on and off depending on whether or not we are touching the ground.

In this video (objectives)…

1. We add 2 sound effects to our game and look at 2 slightly different ways of playing clips.

In this video (objectives)…

1. Public methods can be accessed from other classes. In this lecture we use a public method to stop the player being able to control their character.

In this video (objectives)…

1. We have a minor issue that the player can bounce and trigger multiple SFX and particle effects when crashing. We'll set ourselves a challenge to stop that.

In this video (objectives)…

1. We wrap up this section and get ready for the next one.

In this video (objectives)…

1. Check out what we'll be making in this section of the course!

In this video (objectives)…

1. Lets begin where every game should - with the game design document - and understand the features and mechanics that we'll need for our quiz game.

In this video (objectives)…

1. The first step towards building our game is to add a UI canvas and background image.

In this video (objectives)…

1. UI text comes in many different styles. Let's add the game title and make a home for the question text.

In this video (objectives)…

1. Buttons will allow the player to interact with our game. Let's add some to our canvas and organize them with using a layout group

In this video (objectives)…

1. Scriptable object are a great way to store data, so let's use them to store our question data.

In this video (objectives)…

1. Give your private variables read-only access using a getter method.

In this video (objectives)…

1. A question is nothing without an answer, so let's look at how to store our quiz answers efficiently by using an array.

In this video (objectives)…

1. It's time connect our scriptable objects to our UI. Let's start by learning how to set the text field of the TextMeshPro component in code, using TextMeshProUGUI.

In this video (objectives)…

1. It's time connect our scriptable objects to our UI. However, before we can connect our answers to the buttons, we're going to need to learn about for loops.

In this video (objectives)…

1. Once the player has selected an answer, it would be nice to tell them if they got it right. To do this, we're going to swap the sprite for the button holding the correct answer and replace the question text with a confirmation message.

In this video (objectives)…

1. After the player has selected an answer, they can continue to click on the other answer buttons. Let's put a stop to that by changing the interactable state of the button.

In this video (objectives)…

1. To move the player on to the next question, we're going to implement a turn-based style timer - giving the player a fixed amount of time to answer the question and a fixed amount of time to review the answers.

In this video (objectives)…

1. Let’s finish up our timer by calculating the fill amount for our timer image component and add some additional functionality that our Quiz.cs script will use later on.

In this video (objectives)…

1. With our timer logic set up, let's connect it to our game and finally see it in action!

In this video (objectives)…

1. It's finally time to add some more questions to the game! We could use an array to store them, but let's use the more flexible 'List' instead.

In this video (objectives)…

1. There are many different types of scoring system in games but they all serve a similar purpose - to show the player how well they're doing. For our game, let's look at showing the player how many questions they got right as a percentage.

In this video (objectives)…

1. We use a UI slider to act as a progress bar, to show the player how far they are through the quiz.

In this video (objectives)…

1. Test your knowledge by creating a new canvas that will display the player's final score once the quiz is complete.

In this video (objectives)…

1. Our game is almost finished! We just need a way to; transition between our quiz and end screens, and reload the game if the player wants to play again. We will also fix a few minor bugs by learning about the Awake() method.

In this video (objectives)…

1. Our UI focused quiz game is now complete! Along the way, we learn how to; store data using scriptable objects, loop through lists and arrays using a for-loop, and reload our scenes so the player can try again without having to reload the game.

In this video (objectives)…

1. In this section we'll be using Tilemap to create a 2D sidescrolling platformer.

In this video (objectives)…

1. We look at the core design for this project and outline what features we need for our minimum viable product.

In this video (objectives)…

1. We've brought some sprite sheets into Unity, we now need to slice them up for our use.

In this video (objectives)…

1. Tilemap is a powerful tool for creating 2D games. In this lecture we understand the main aspects of Tilemap and get started using it.

In this video (objectives)…

1. Our level is going to have many layers to it - platforms, background, water, pickups, etc. In this lecture we look at how to create multiplayer layers using Tilemap and sorting layers.

In this video (objectives)…

1. Unity Rule tiles are a powerful way for us to paint a tileset and have them automatically recognise edges, corners, and other elements and display the correct art asset. This involves setting up the logic, or rules, for our rule tile.

In this video (objectives)…

1. We use 4 of the sprites from our spritesheet to create an idle animation for our player. This involves setting up an animator controller and creating an anim file.

In this video (objectives)…

1. We implement our running and climbing states and add the appropriate animations for each. We set up parameters that can be used as conditions to transition from one state to another.

In this video (objectives)…

1. We play around with prefabs and learn the basics of how they work.

In this video (objectives)…

1. We add collision for our player and for our platforms. To do this we'll need to use a composite collider and a tilemap collider.

In this video (objectives)…

1. We'll set up our input system using the Messages option and add an additional input action with key bindings.

In this video (objectives)…

1. Now that we have the basic input system being received we need to turn that into player movement by adding velocity to the player's Rigidbody.

In this video (objectives)…

1. We flip our player sprite by looking at our velocity and seeing what direction we are running in. This will involve using Mathf.Abs, Mathf.Sign and Mathf.Epsilon

In this video (objectives)…

1. We change the state of our animation with the animator control based upon whether the player is moving the player and it therefore has velocity.

In this video (objectives)…

1. We'll create our OnJump() method which can be called when our Jump action button is pressed, resulting in our player jumping. We'll also play with gravity and movement speed to get the tuning as we'd like.

In this video (objectives)…

1. To remove the issue of our player being able to spam the jump button and fly way off the screen we need to check if they are touching the ground by using Collider2D.IsTouchingLayers().

In this video (objectives)…

1. We need to check if the player is touching a ladder and create code to allow vertical movement in that moment.

In this video (objectives)…

1. Our player slowly drifts down to earth while on the ladder. Instead of this behaviour we want the player to stay where they are and not slide.

In this video (objectives)…

1. When our player is running up or down the ladder we want to play our climb animation.

In this video (objectives)…

1. Let's set up a follow camera with some dampening to soften our jump. We'll use a Cinemachine virtual camera to do this.

In this video (objectives)…

1. We set up a way to limit how far a camera can travel using the Cinemachine Confiner Extension.

In this video (objectives)…

1. Cinemachine makes life super easy for us to transition between different cameras based upon our animation state. We set up a few cameras that will blend from one to another based upon our actions.

In this video (objectives)…

1. We'll change the friction and bounciness of two Physics Material 2D materials so that we can create bouncy mushrooms and so we can stop the player sticking to the wall.

In this video (objectives)…

1. We set up a feet collider and use that to check if the player is able to jump.

In this video (objectives)…

1. We add all of the components and base animation to get our enemy ready for movement.

In this video (objectives)…

1. We give our character a reverse periscope(TM) and use OnTriggerExit2D() to let it know that its time to turn around and move the other direction.

In this video (objectives)…

1. We start our player death functionality by stopping the player from being able to move after the collide with an enemy.
