Why input drives player interaction in Unity - Test Your Understanding

Practice - 5 Tasks

easy

Complete the code to read horizontal input from the player.

Unity

float move = Input.GetAxis([1]);

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

A"Vertical"

B"Fire1"

C"Jump"

D"Horizontal"

💡 Hint

Common Mistakes

Using "Vertical" instead of "Horizontal" will read up-down input.

Using "Jump" or "Fire1" reads button presses, not axis movement.

The Input.GetAxis method reads input from the specified axis. To get left-right movement, use "Horizontal".

Complete the code to move the player horizontally based on input.

Unity

transform.Translate(move * [1] * Time.deltaTime, 0, 0);

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

💡 Hint

Common Mistakes

Using gravity or jumpForce will not move the player horizontally.

Using health is unrelated to movement.

The speed variable controls how fast the player moves horizontally.

hard

Fix the error in the code to detect when the player presses the jump button.

Unity

if (Input.GetButtonDown([1])) {
    Jump();
}

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

A"Fire1"

B"Horizontal"

C"Jump"

D"Vertical"

Attempts:

3 left

💡 Hint

Common Mistakes

Using "Fire1" detects firing, not jumping.

Using "Horizontal" or "Vertical" reads axis movement, not button presses.

The jump button is named "Jump" in Unity's input system. Using this name detects jump presses.

4fill in blank

hard

Fill both blanks to create a dictionary that maps input names to their current values.

Unity

var inputValues = new Dictionary<string, float> {
    {"Horizontal", [1],
    {"Vertical", [2]
};

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

AInput.GetAxis("Horizontal")

BInput.GetButtonDown("Jump")

CInput.GetAxis("Vertical")

DInput.GetButton("Fire1")

Attempts:

3 left

💡 Hint

Common Mistakes

Using button methods like GetButtonDown or GetButton returns bool, not float.

Mixing axis and button input methods causes type errors.

Use Input.GetAxis to get the current float value of the "Horizontal" and "Vertical" axes.

5fill in blank

hard

Fill all three blanks to check if the player pressed the fire button and move the player accordingly.

Unity

if (Input.GetButtonDown([1])) {
    Shoot();
}

float move = Input.GetAxis([2]);
transform.Translate(move * [3] * Time.deltaTime, 0, 0);

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

A"Fire1"

B"Horizontal"

Cspeed

D"Jump"

Attempts:

3 left

💡 Hint

Common Mistakes

Using "Jump" instead of "Fire1" for firing input.

Using button input names for axis input causes errors.

Forgetting to multiply by speed causes no movement.

Use "Fire1" to detect firing, "Horizontal" to get horizontal movement input, and multiply by speed to move the player.
