3D coordinate system in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a Vector3 at position (1, 2, 3).

Unity

Vector3 position = new Vector3([1]);

Drag options to blanks, or click blank then click option'

A[1, 2, 3]

B1 2 3

C(1, 2, 3)

D1, 2, 3

💡 Hint

Common Mistakes

Using spaces instead of commas

Adding brackets around the values

In Unity, Vector3 constructor takes three float values separated by commas without brackets.

Complete the code to move an object 5 units along the positive z-axis.

Unity

transform.position += new Vector3(0, 0, [1]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using negative values to move forward

Using zero which causes no movement

To move 5 units forward along the z-axis, add 5 to the z component.

hard

Fix the error in the code to correctly set the y position to 10.

Unity

Vector3 pos = transform.position;
pos.y = [1];
transform.position = pos;

Drag options to blanks, or click blank then click option'

AVector3(0, 10, 0)

B"10"

C10

Dpos.y = 10

💡 Hint

Common Mistakes

Using quotes around numbers

Assigning a Vector3 instead of a float

The y component should be assigned a numeric value 10, not a string or expression.

4fill in blank

hard

Fill both blanks to create a Vector3 pointing up with length 1.

Unity

Vector3 up = new Vector3([1], [2], 0);

Drag options to blanks, or click blank then click option'

A0

💡 Hint

Common Mistakes

Swapping x and y values

Using negative values for up

A vector pointing straight up has x=0 and y=1.

5fill in blank

hard

Fill all three blanks to create a Vector3 scaled by 2 from (1, 3, 4).

Unity

Vector3 scaled = new Vector3([1], [2], [3]);

Drag options to blanks, or click blank then click option'

A1

B6

C8

D2

💡 Hint

Common Mistakes

Using original values without scaling

Mixing up the order of coordinates

Scaling (1, 3, 4) by 2 gives (2, 6, 8).
