🧪 Practical Task: Transform and Hierarchy

🎯 Goal

Learn to control position, rotation (Euler and Quaternion), scale, and object hierarchy through the Inspector and scripts in Unity.

🧱 Scene for the task

Create a new 3D scene. It will contain:

A platform (Cube)
A red cube (ChildCube)
A blue cube (EnemyCube)
An empty parent object (ParentHolder)

📝 Tasks (complete in order)

1️⃣ Hierarchy (Parent/Child)

Create ParentHolder (Create Empty).
Make ChildCube (red cube) a child of ParentHolder (drag in the Hierarchy).
Set ChildCube's local position relative to ParentHolder: (1, 0, 0).
Move ParentHolder to (3, 2, 0). Where does ChildCube end up? (Answer: at world position (4, 2, 0)).

2️⃣ Position and rotation using Euler

Place EnemyCube (blue cube) at position (0, 1, 5).
Rotate it around the Y axis by 45° via the Inspector (Euler).
Write a short script RotateEnemy that in Update() increases transform.eulerAngles.y by 30° every second. Attach it to EnemyCube.

3️⃣ Rotation using Quaternion (LookRotation)

Create an empty object Target at position (2, 1, 0).
Write a script FaceTarget for ChildCube: use Quaternion.LookRotation so that the red cube always faces Target. Do not use Euler.
Test: move Target with the mouse in Scene View — ChildCube should rotate instantly.

4️⃣ Scale and global coordinates

Set ParentHolder's scale to (2, 1, 1).
Print to the console (Debug.Log) the global scale (transform.lossyScale) for ChildCube. Explain why it is not (1,1,1).
Change ChildCube's local scale to (0.5, 1, 1). Calculate the final X size manually.

5️⃣ Bonus (optional)

Write an Orbit script that rotates ChildCube around ParentHolder in a circle using transform.RotateAround. Parameters: speed 30° per second, Y axis.

✅ What is being checked (for self-checking)

Scripts RotateEnemy, FaceTarget, Orbit (if done).
Console output values (task 4) and the answer to the lossyScale question.
