Input axis for smooth movement in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to get horizontal input for smooth movement.

Unity

float horizontal = Input.[1]("Horizontal");

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

AGetButtonDown

BGetAxis

CGetKeyDown

DGetButtonUp

Attempts:

3 left

💡 Hint

Common Mistakes

Using GetButtonDown instead of GetAxis causes no smooth movement.

Using GetKeyDown returns true only on key press, not continuous input.

Input.GetAxis("Horizontal") returns a smooth value between -1 and 1 based on player input.

medium

Complete the code to move the player smoothly on the x-axis.

Unity

transform.Translate(horizontal * speed * Time.[1]);

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

AdeltaTime

CfixedDeltaTime

DunscaledDeltaTime

💡 Hint

Common Mistakes

Using fixedDeltaTime in Update can cause inconsistent movement.

Using timeScale or unscaledDeltaTime is not suitable for normal movement timing.

Time.deltaTime ensures movement is smooth and frame rate independent.

3fill in blank

hard

Fix the error in the code to read vertical input smoothly.

Unity

float vertical = Input.[1]("Vertical");

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

AGetButton

BGetAxisRaw

CGetAxis

DGetKey

Attempts:

3 left

💡 Hint

Common Mistakes

Using GetAxisRaw causes jerky movement instead of smooth.

Using GetButton or GetKey returns boolean, not float values.

Input.GetAxis returns smooth input values, while GetAxisRaw returns immediate -1, 0, or 1.

4fill in blank

hard

Fill both blanks to create a dictionary of axis values for movement.

Unity

var movement = new Dictionary<string, float> { {"horizontal", Input.[1]("Horizontal")}, {"vertical", Input.[2]("Vertical")} };

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

AGetAxis

BGetButtonDown

CGetAxisRaw

DGetKeyDown

Attempts:

3 left

💡 Hint

Common Mistakes

Using GetButtonDown or GetKeyDown returns booleans, not floats.

Using the same method for both axes may not fit all movement needs.

Use GetAxis for horizontal to get smooth input, and GetAxisRaw for vertical to get immediate input.

5fill in blank

hard

Fill all three blanks to create a movement vector and apply it smoothly.

Unity

Vector3 move = new Vector3(Input.[1]("Horizontal"), 0, Input.[2]("Vertical"));
transform.Translate(move * speed * Time.[3]);

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

AGetAxis

BGetAxisRaw

CdeltaTime

DGetButton

Attempts:

💡 Hint

Common Mistakes

Using GetButton returns bool, not float values.

Not using deltaTime causes movement to depend on frame rate.

Use GetAxis for smooth horizontal input, GetAxisRaw for vertical raw input, and deltaTime for smooth frame-independent movement.
