# Complete Unity Developer - Section 5 - Block Breaker

This is the [Complete Unity Developer](http://gdev.tv/cudgithub) - one of the most successful e-learning courses on the internet! Completely re-worked from scratch with brand-new projects and our latest teaching techniques. You will benefit from the fact we have already taught over 360,336 students game development, many shipping commercial games as a result.

You're welcome to download, fork or do whatever else legal with all the files! The real value is in our huge, high-quality online tutorials that accompany this repo. You can check out the course here: [Complete Unity Developer](http://gdev.tv/cudgithub)

**Useful Links**  
+ [Unity - Execution Order of Event Functions](http://docs.unity3d.com/Manual/ExecutionOrder.html)

### Z-Depth in 2D games ###

+ What z-depth means.
+ **The problem**: sprites becoming semi-transparent or invisible for unknown reasons.
+ **The solution**: look at the z-position of sprites relative to the background.

### Setting Up Your Play Space ###

### Ball + Gravity + Colliders = Fun ###

+ Add a ball to your space
+ Import the ball sprite to Sprites folder.
+ Set a sensible “Pixels Per Unit” value.
+ Place the ball in the middle of the play space.

### Colliders, Triggers & Collisions ###

+ What are colliders
+ If colliders overlap during a frame then…
+ … messages may be passed by the engine.
+ What is message passing?
+ Signatures of messages passed
+ Types of colliders explained

### Tidying Up Before Moving On ###

+ Delete Music Player on Level_01 scene.
+ Setting Game window to 800 x 600.
+ Two handy keyboard shortcuts.
+ Remove Canvas and Event System from Level_01.
+ Make loose collider load next level.

### Choosing Collider Type In Unity ###

+ Add our brick sprite as a player paddle.
+ Choosing our paddle collider type.
+ Rigid Body 2D
+ CHALLENGE: Add components to our paddle.

### Using Physics Materials ###

+ What is a physics material.
+ Add a bouncy material.
+ Observe funky physics.

### Movement By Mouse ###

+ Using **Input.MousePosition.x**
+ **Screen.width** to get screen width.
+ Move the paddle **this.transform.position**
+ Introducing **float** and **Vector3**.
+ Using **Mathf.Clamp** to constrain paddle.
+ Fix the paddle's “Pixels per unit” to 128.

**Useful Links**  
+ [Unity - Scripting API](https://docs.unity3d.com/ScriptReference/)

### Launching Ball On Mouse Click ###

+ Start the ball sitting on the paddle.
+ Capture the relative position from the editor.
+ Respond to **Input.GetMouseButtonDown(0)**.
+ **rigidbody2D.velocity** to launch the ball.
+ Using **bool hasStarted** to keep track.

### Invisible Colliders & Gravity Scale ###

+ Setup all your play space wall colliders.
+ Adjust the initial velocity and gravity.
+ Understanding Gravity Scale

### Creating & Using Unity Prefabs ###

+ What is a prefab in Unity
+ Why prefabs are useful.
+ Setting up your prefabs.
+ How prefab linking works.

### Unity Editor Snap To Grid ###

+ How Edit > Snap Settings works.
+ Snap initially to get on the grid.
+ You can do this with multi-select.
+ Hold cmd (ctrl) while dragging!
+ Build your first level

### Making Everything A Prefab ###

+ Make everything a prefab!
+ Set Main Camera background to black.
+ Move & group Loose Collider.
+ Test by making new level.
