Animation states and transitions in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to get the Animator component.

Unity

Animator animator = GetComponent<[1]>();

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

AAnimator

BAnimation

CAnimatorController

DAnimationClip

💡 Hint

Common Mistakes

Using 'Animation' instead of 'Animator' causes errors because 'Animation' is an older system.

Trying to get 'AnimatorController' which is not a component.

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

Complete the code to trigger a transition using a trigger parameter.

Unity

animator.[1]("Jump");

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

APlay

BSetBool

CSetTrigger

DResetTrigger

💡 Hint

Common Mistakes

Using 'SetBool' instead of 'SetTrigger' won't trigger the transition.

Using 'Play' plays an animation state directly but doesn't set parameters.

Use SetTrigger to activate a trigger parameter and start a transition in the Animator.

Fix the error in the code to check if the Animator is currently in the 'Run' state.

Unity

bool isRunning = animator.GetCurrentAnimatorStateInfo(0).[1]("Run");

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

CstateName

DGetName

💡 Hint

Common Mistakes

Trying to compare 'name' property directly to a string causes errors.

Using 'GetName' which does not exist.

IsName is a method that checks if the current state matches the given name. Comparing name or other properties to a string directly won't work.

4fill in blank

hard

Fill both blanks to smoothly transition to the 'Attack' animation state.

Unity

animator.[1]("Attack", 0, [2]);

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

APlay

BSetTrigger

C0f

D0.5f

💡 Hint

Common Mistakes

Using 'SetTrigger' with a float parameter causes errors.

Using normalized time 0.5f starts animation halfway through.

Play starts the animation state immediately. The third parameter is the normalized time, where 0f means start from the beginning.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping animation states to their durations, filtering only states longer than 1 second.

Unity

var durations = new Dictionary<string, float> { {"Idle", 1.2f}, {"Walk", 0.8f}, {"Run", 1.5f} };
var filtered = durations.Where(kv => kv.Value [1] [2]).ToDictionary(kv => kv.Key, kv => kv.Value [3] 0);

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

D<

💡 Hint

Common Mistakes

Using '<' filters shorter durations, not longer.

Subtracting a non-zero value changes durations unexpectedly.

The code filters states with duration greater than 1 second, then subtracts 0 from the value (no change). The operator > and value 1 filter correctly. The subtraction - 0 keeps the value unchanged.
