Add new asteroid types

1. Start by duplicating (2x) the asteroid object(drag from prefab) to scene.

1. Customize each one by replacing the model with the alternates.
2. Adjust the colliders.
3. Rename and save as new prefabs.

Change the GameController to spawn all three

Change

public GameObject hazard;

to

public GameObjects[] hazards;

Change the spawn to select a random one from the list.

Remember to go back to the GameController Object and add those prefabs to the hazards list.

Star Field

Drag and drop the prefab starfield into the scene

Set the Y to just above the background.

Optionally fiddle with the lifetime and speed constants.

Rolling Cloud

Duplicate the Background as a child of background

Use the transform too. and Use vertex snapping(v) to get them butted from end to end.

This gives you two whole pieces to run.  The image is built to be seamless.

Add a new c# backgroundScroller script.  Not the mathf.repeat.  This is the key.

Enemies

So much

Create empty “Enemy” placeholder object and fill it with the model and exhaust model.

add rigid body and collider, then adjust.

Add movement compoent and make the value -5.

Add the destroy by contact component.

Make it a Prefab

Add the prefab to the gamecontroller’s list of hazards.

Run it.

Evasive manuver

Go to the publish settings.

Create & Select a new folder ({root}/Builds)

Build it.

Play it. (NOT on Chrome.)

More like chapter 14.  Add two new labels. Game Over, Restart.  Add references in the GameController object too.   They are both blank at the start of the game.   They change when game over occurs.

That Works. You’ve got game!

Inside

You’ve seen it before.  Add these publics to the the GameController.

Then Add the components on the screen, then drag and drop.

Include UpdateScore() in the Start routine.

Outside

Make a public addscore routine in game controller

In any routine that needs to add a score, get a reference to the GameController, then at the right time, call the new routine. ( the AddScore() routines above doesnt match below, but  you get the picture.)

Music… Drag and drop the music to the GameController Object(play on awake, loop)

Drag and drop audio into the prefabs like explosion and you don’t have to program anything.

Then drag and drop the audio clip and confirm “play on awake” is checked.

That takes care of explosions. Now shooting.

Drag and drop the audio clip onto the player object.(no play on awake)

We a single control by adding loops

while(!gameOver)

for(i=0;i<#per4 wave; i++)

spawn rock

Part 2 – Removing those explosions after a few seconds

1.  Create a “DestroyByTime” Object
2. Attach that to the prefab for each of the explosions.

Game Controller (spawning waves)

It sits at the top of the game view as a new object with a script called “GameController”

At start it shoots off a random asteroid.  We will

Creat the script with two params (where to launch the asteroid) and what to launch(asteroid prefab)
