10:05 Today’s Notes & Attendance

Week 29
Fire Drill tomorrow (Wed) at 10:15am
Mid Quarter ends on Friday

10:10 SkySweeper – Let’s add in our Particle Shooting!

Let’s add a new input to your Player Controls Input System for shooting. Then we can set up a particle system for our weapons system. We can also add a cross hair system to assist with aiming.

10:50 Morning Break (10 minutes)

11:00 Building Our Next Game – Your Independent Build

Do you remember what my favorite Arcade game is? It’s Arkanoid!

We’ve got enough skills to create a nice little breakout game – or at least a minimal viable product to see how everything works.

You’ll need to make some sprites. Photoshop is good for that. I think the original game the sprites are 32 pixels high and about 75 pixels wide for blocks The paddle is 16 pixels high and 32 pixels wide (I think) but you can design yours anyway you want using any style that inspires you…

Create a New Project called BreakOut in the 2D space.

Sprite Assets we need to create: Ball, colored blocks, paddle, border

Physics Material (Bouncy) for the Ball

For the paddle we are going to use a Polygon Collider and make the collider a little uneven so ball bounces with some randomness

Code you need to create:

Movement Script for Paddle using the New Input System(you know how to do this – look at PinBall)
- Might be nice to have a variable to adjust paddle speed
- Also be nice to limit how far left and right the paddle can go
Collision Script to Destroy Blocks (Example)
A Ball Script (see code snippet below)

PreFabs will make our life easier by creating one for each block to include:

Correct Scale
Box Collider 2D
Collision Script to go on the blocks

Background Image – here is one you can use or go make your own

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Ball : MonoBehaviour
{
    // Movement Speed
    public float speed = 10.0f;

    // Use this for initialization
    void Start()
    {
        GetComponent<Rigidbody2D>().velocity = Vector2.up * speed;

    }
}

This code is going to use a Vector to move the ball up at the start of the game. We can use the speed variable to change the speed of the ball.

Build, Play Test

Your Breakout Game will be due on Friday, May 8th. You will have some class time for this.

Deliverables:

A game scene with all assets
A ball that breaks (destroys) bricks
A score that adds up (can you code a High Score?)
A Win or Lose Condition (Killbox) and messaging (like you lost)

It would be nice to have:

Sounds
Multiple Players / Health
Bricks that have different scoring
PowerUp or Invoke/Instantiate something
An Opening Splash screen when the game begins
Multiple Levels

This is an individual assignment. However, use each other to assist with your questions.

12:25 Pixel Perfect Practice Session

Sprites (Working towards Pixel Perfect) in Photoshop

Tools for Pixel Art – Photoshop, Aseprite, Piskel
Games with great pixel art – HyperLightDrifter, ScottPilgrim, Video of Pixel Games
Character Size – the evolution from 16 to 128 pixels (DonkeyKong Mario 16 pixels!)
Setting up in Photoshop, brushes, shapes, symmetry, text
Line theory – for pixel perfect lines-
Character Creation or Object Creation
Exporting

Line Theory:

A “jaggy” is an unintentional break in a otherwise smooth line or curve. This makes the line look strange and pointy, too many jaggies can ruin an artwork.

To make a smooth line you should have the same number of pixels on every “step” of the line, for example: 1, 1, 1, 1, is a smooth line whereas 1, 2, 1, 1, is not.

A smooth curve always follows a pattern. When you are moving towards the centre of the curve the number of pixels should be lower than or the same as the previous number of pixels.

When moving away from the center you should do the opposite, the number should be higher or the same as the one before it. For example: 6, 3, 2, 1, 1, 1, 2, 4, 4 is a smooth curve
