1fill in blank

easy

💡 Hint

Common Mistakes

Using Animation instead of Animator causes errors.

Trying to get AnimatorController directly is incorrect.

The Animator component controls animations in Unity. Use GetComponent<Animator>() to access it.

Complete the code to set the Animator parameter 'isRunning' to true.

Unity

animator.SetBool("isRunning", [1]);

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

ATrue

B"true"

C1

Dtrue

💡 Hint

Common Mistakes

Using string "true" instead of boolean true.

Using integer 1 instead of boolean true.

The SetBool method expects a boolean value true or false, not a string or number.

Fix the error in the code to trigger the 'Jump' animation using a trigger parameter.

Unity

animator.[1]("Jump");

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

ASetBool

BSetTrigger

CSetFloat

DPlay

💡 Hint

Common Mistakes

Using SetBool or SetFloat for triggers causes no animation change.

Using Play requires animation state name, not parameter.

To activate a trigger parameter in Animator, use SetTrigger. Other methods set different parameter types.

4fill in blank

hard

Fill both blanks to create a dictionary that maps animation states to their speed multipliers.

Unity

var animationSpeeds = new Dictionary<string, float> { {"Idle", [1], {"Run", [2] };

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

A1.0f

B2.5f

C0.5f

D3.0f

💡 Hint

Common Mistakes

Using integer values without 'f' suffix causes errors.

Mixing up speeds for Idle and Run.

Idle animation usually plays at normal speed 1.0f, while Run is faster, e.g., 2.5f.

5fill in blank

hard

Fill all three blanks to create a filtered dictionary using LINQ that stores animation names and their lengths if length is greater than 1 second.

Unity

var longAnimations = animations.Where(anim => anim.length [3] 1.0f).ToDictionary(anim => [1], anim => [2]);

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

Aanim.name

Banim.length

C>

D<

💡 Hint

Common Mistakes

Using '<' instead of '>' in the condition.

Swapping name and length in the dictionary.

This code collects animation names and lengths only if the length is greater than 1 second.
