Summary - Transform

Reinforce Transform usage with a summary task.

Transform Overview

The Transform component manages an object's position, rotation, and scale. position represents world position, while localPosition represents position relative to the parent. You can use Vector3 to assign new coordinates, Translate for relative movement, and Quaternion to set rotation.

transform.position = new Vector3(3, 0, 2);
transform.Translate(1, 0, 0);
transform.rotation = Quaternion.Euler(0, 90, 0);

Exercise Complete the Transform Review Task

Inside the Start method of a Unity C# class, set the object's world position to (2, 0, 3). Then move it one unit along the X axis using Translate and set its rotation to 90 degrees around the Y axis. Finally, print its new world position in the Console window.

Show example solution

using UnityEngine;

public class TransformReview : MonoBehaviour
{
    void Start()
    {
        transform.position = new Vector3(2, 0, 3);
        transform.Translate(1, 0, 0);
        transform.rotation = Quaternion.Euler(0, 90, 0);
        Debug.Log(transform.position);
    }
}

Test yourself

Which property should be used to change an object's position relative to its parent?
- transform.localPosition
- transform.rotation
- transform.position
- transform.Translate
Show answer

transform.localPosition — localPosition determines the object's position relative to its parent's coordinate system.

Complete the Transform Rotation

transform.rotation = Quaternion.Euler(0, ____, 0);

Show answer

transform.rotation = Quaternion.Euler(0, 90, 0);

Review Transform Operations

transform.position

Represents world position
transform.Translate
