STEP 58: Edit the GameController script. Save and return to unity
STEP 59: Edit the DestroyByContact script. Save and return to unity
STEP 60: Add Score Text text component into the Score Text slot of GameController script
STEP 61: Set the score value in the DestroyByContact script of the Asteroid prefab to 10. Save and play to test if the score is being displayed.
STEP 62: Add a new UI Text and name it Restart Text position it to the top right of the screen
STEP 63: Add a new UI Text Component and name it as Game Over Text reset its text property and position it as per choice.
STEP 64: To the GameController script add code to print game over when the player ship collides with the hazards and to indicate the player to press R if he wishes to restart the game. Save the script and return to Unity.
STEP 65: Edit the DestroyByContact script to add reference to the gameOver method. Save and return to unity.
STEP 66: Drag and drop Game Over and Restart Text to their respective slots in the
GameController script. The game is completely ready to play
STEP 67: Go to File – Build Settings. Drag and drop MainScene into the slot for scenes. Click Build and save a build location. Finally you can Play the game.

AIM: Roll a Ball – Unity Game
STEP 1: Open Unity. Create a New Project name it, save a location. Select 3D and Create
STEP 2: Create a new scene. Go to File – Save As and save Scene. Name as Main
STEP 3: Create a plane Hierarchy – 3D Object – Plane Rename as Ground. Reset its transforms. Turn off Grid line in Gizmos menu. Set Scale X=Z=2
STEP 4: Create a sphere Hierarchy – 3D Object – Sphere Rename as Player. Reset its transforms. Set Position Y=0.5
STEP 5: In the Project folder, create a new folder and name it as Material. Now click on
Material and create a new material and name it as Background. Set Albedo: R=0, G=32,
B=64. Drag and drop material onto the Ground (Plane)
STEP 6: Select Directional Light. Set Rotation Y=60
STEP 7: Add Rigidbody component to the Player game. Uncheck Is Kinematic
STEP 8: Create a new folder in the Project folder and rename as Scripts.
STEP 9: Add script component to the Player object and name it as PlayerController. Drag and drop it to the Scripts folder
STEP 10: Edit the script to move the player. Save and return to Unity. Set Speed =10. Play to test
STEP 11: Set camera value as Position Y=10 Rotation X=45.
STEP 12: Add a new script to the Main Camera. Name it as CameraController. Drag and drop
it to the script folder
STEP 13: Edit the script to move the camera relative to the player. Save and return to Unity.
STEP 14: Drag and drop Player object to Player slot of CameraController script. Play the game to see the camera moving as the player moves
STEP 15: Create a new gameobject and name it as Walls. Reset its transforms
STEP 16: In the Hierarchy - + - 3D Objects – Cube. Reset its transforms and name it
WestWall. Make it the child of Wall game object. Set Scale values as X=0.5, Y=2, Z=20.5. Set Position X=-10
STEP 17: Duplicate West Wall using ctrl + D. Rename as EastWall and set Position X=10
STEP 18: Duplicate EastWall using ctrl + D. Rename as NorthWall and set Position Z=10.
Set Scale values as X=20.5, Y=2, Z=0.5
STEP 19: Duplicate NorthWall using ctrl + D. Rename as SouthWall and set Position Z=-10.
Play to test if the ball leaves the boundary or not
STEP 20: Deactivate Player game object. Create a new Cube object name it as PickUps.
Reset its Transforms. Set Position Y=0.5. Rotate X=Y=Z=45 and Scale X=Y=Z=0.5
STEP 21: Add a Script component to the PickUps and name it as Rotator. Drag and drop it into the Scripts folder.
STEP 22: Edit the Rotator script to rotate the pickup objects. Save and return to Unity. Play to test.
STEP 23: In the Assets folder create a new Folder name it as Prefab. Drag and drop PickUps from hierarchy into the Prefabs folder.
STEP 24: Create a new game object name it as PickUps. Reset its transforms and make PickUps cube from hierarchy child of PickUps gameobject. Duplicate the PickUp cubes as much as you want and position them accordingly.
STEP 25: Create a new Material name it as PickUp and set its Albedo to a bright yellow. Add this material onto the PickUps in the Prefabs folder
STEP 26: Reactivate the Player object. Edit the PlayerController script to collect the PickUps.
Save and return to Unity
STEP 27: Create a new tag called Pick Up and tag the PickUps object in the Prefabs Folder. Select isTrigger Property of the Collider on. Add a Rigidbody component to the PickUps Prefab. Check the Is Kinematic option. Play to test.
STEP 28: Go to Hierarchy – UI – Text. Name as CountText. Position it to the top left side of the screen and set its default text to Count Text. Similarly create a WinText and position it at the center and set its default text to Win Text
STEP 29: Edit the PlayerController script to display the count of pickups collected and display win text if all pickups are collected. Save and return to Unity
STEP 30: Drag and Drop CountText into the Count Text text slot and WinText into the Win text text slot. Play to test.
STEP 31: Go to File – Build Settings. Drag and drop Main Scene into the slot for scenes. Select the platform on which you wish to build the game. Click Build and save a build location. Finally, you can play the game.
