3D Game Development Basics

Use a computer suitable for a modest Unity project, Unity Hub, a compatible editor version and a C# development environment. Choose a simple 3D project template and confirm that it opens and enters Play mode. Learn the difference between the hierarchy, scene view, game view, inspector and project assets. Keep the editor version and installed packages in your notes, especially when following older recordings. Use a small set of permitted assets and avoid adding unnecessary packages while learning. Create a scene containing a ground surface, a camera and a simple object before beginning character and animation exercises.

A Unity scene contains GameObjects whose behavior comes from attached components. A Transform represents position, rotation and scale. In C#, variables hold values, methods perform actions and classes define behavior. Start is commonly used for initialization and Update for frame-based work. Use elapsed time appropriately so movement does not depend entirely on frame rate. Colliders describe interaction boundaries, while rigid-body components participate in physics behavior. Separate player input, movement and feedback when practical. Connect animation to clear state changes. Add a simple UI and audio cue only after the underlying interaction works. Test a standalone build as part of the project workflow, not just the scene in the editor.

Build a small 3D prototype in which a player or controllable object completes a clear objective. Include a usable camera, at least one interaction, a visible success or failure state and a restart action. Organize assets and scripts so another learner can locate them. Test movement, collision boundaries, restart behavior and a packaged build supported by your editor setup. Provide editor-version information, controls and a short explanation of the scripts. Assess stable behavior, clear feedback and the ability to reproduce the project. Keep the scope small enough to finish and polish one complete gameplay loop.

Lesson focus: Import Assets in Unity 3D - Rotate Camera Around The Object. Separate scene layout, camera behavior and player control. Test movement and inspect transform values. Reproduce the central example in your own practice environment, then change one meaningful input, rule or interface behavior independently. Record the expected result before running it and compare that result with what the project actually does. Test a normal case and a boundary or unexpected-input case suited to this lesson. Keep the project or exercise files together with a short explanation of the change and the steps needed to repeat it.

Lesson focus: Character Control - How to control character in Unity 3D. Separate scene layout, camera behavior and player control. Test movement and inspect transform values. Reproduce the central example in your own practice environment, then change one meaningful input, rule or interface behavior independently. Record the expected result before running it and compare that result with what the project actually does. Test a normal case and a boundary or unexpected-input case suited to this lesson. Keep the project or exercise files together with a short explanation of the change and the steps needed to repeat it.
