This document provides a step-by-step guide to creating a simple 3D game using Unity, focusing on setting up the game environment by creating the ground and the player object. It includes instructions on managing project files, manipulating 3D objects, and applying materials and lighting. The document also covers scripting for player movement and camera control, culminating in testing the game functionality.

Rollerball: 1 of 2
- 1. Based on Roll-a-ball video tutorial from Unity Technologies Part 1 @shahedC WakeUpAndCode.com
- 2. Getting Started > Creating the Ground > Creating the Player > Materials, Colors & Lighting > 3D Physics & Movement Controlling the Camera
- 6. Select 3D (not 2D) Click [Create project]
- 10. , then click [Save]… Name your scene “PlayingField.unity” Inside “Scenes” Subfolder…
- 11. Verify Saved Scene in Project panel Verify Scene Name in Title Bar
- 13. Click GameObject 3D Object Plane Click Create 3D Object Plane In the top menu… In the Hierarchy panel…- OR -
- 15. Right-click to rename Enter “Ground”
- 16. Select “Ground” in Hierarchy Click gear icon next to Transform then click “Reset”
- 18. With “Ground” selected in hierarchy… … press ‘F’ on your keyboard to focus on it … move your cursor to the Scene
- 19. Scroll the mouse wheel over your scene to zoom in/out
- 20. In the Scene panel, click the Gizmos dropdown to toggle “Show Grid”
- 21. Click on the Scale tool, while the Ground is selected… … then, drag the handles to resize the ground
- 22. Manually enter Scale values in the Ground’s Transform component Scale: X = 2, Y = 1, Z = 2
- 24. Click GameObject 3D Object Sphere Click Create 3D Object Sphere In the top menu… In the Hierarchy panel…- OR -
- 25. Position Sphere at X = 0, Y = 0.5, Z = 0
- 28. In the Project panel, click Create dropdown then, select “Folder”
- 29. In Project panel, click Create then, select “Folder” Rename it “Materials”
- 30. In Project panel, click Create then, select “Material” Rename it “GroundMaterial” Repeat for “BallMaterial”
- 31. For each material... Update color in Inspector window (click white square)
- 32. • Red • Green • Blue • Alpha (Transparency)
- 33. Verify that GroundMaterial and BallMaterial have different colors.
- 34. Drag each material from Project panel to the Scene panel
- 35. Update Direction Light in Inspector Rotation: X = 50, Y = 60, Z = 0
- 37. With “Ball” selected in the Hierarchy panel… Click Component Physics RigidBody
- 38. With “Ball” selected in the Hierarchy panel, click Add Component Physics Rigidbody
- 40. In the Project panel, click Create dropdown Then select “Folder”, name it “Scripts”
- 41. In the Project panel, click Create dropdown Then select “C# Script”, name it PlayerController
- 42. With “Ball” selected... … Drag script into Ball Verify Script Component!
- 44. Add FixedUpdate() method … just before last curly brace
- 45. Inside FixedUpdate() method… Calculate 3D movement
- 46. Define rb just before Start() Initialize inside Start() method Add Force inside FixedUpdate()
- 47. Click Play button, move around with arrow keys!
- 48. Define public speed variable Multiply speed with movement
- 49. With “Ball” selected... Set Speed = 10
- 50. Click Play button, move around with arrow keys!
- 52. Set Camera Position and Rotation • Position: X = 0, Y = 10, Z = -10 • Rotation: X = 45, Y = 0, Z = 0
