Practice - 5 Tasks

1fill in blank

easy

Complete the code to set an Animator parameter named "speed" to a float value.

Unity

Animator animator = GetComponent<Animator>();
animator.SetFloat("speed", [1]);

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

A5.0f

Btrue

C1

D"fast"

💡 Hint

Common Mistakes

Using a boolean or string instead of a float.

Forgetting the 'f' suffix for float literals.

The SetFloat method requires a float value. Here, 5.0f is a float literal.

2fill in blank

medium

Complete the code to check if the Animator parameter "isJumping" is true.

Unity

Animator animator = GetComponent<Animator>();
if (animator.GetBool("isJumping") == [1]) {
    // Jump logic here
}

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

Atrue

Bfalse

C1

Dnull

💡 Hint

Common Mistakes

Comparing to 1 instead of true.

Using false instead of true.

The GetBool method returns a boolean. To check if the parameter is true, compare it to true.

3fill in blank

hard

Fix the error in the code to set the Animator trigger parameter "attack".

Unity

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

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

ASetBool

BGetTrigger

CSetFloat

DSetTrigger

💡 Hint

Common Mistakes

Using SetBool or SetFloat instead of SetTrigger.

Trying to get a trigger value with GetTrigger (which doesn't exist).

To activate a trigger parameter, use SetTrigger. Other methods are for different parameter types.

4fill in blank

hard

Fill both blanks to create a dictionary of animation parameters with their types.

Unity

var animationParams = new Dictionary<string, [1]>() {
    {"speed", [2].Float},
    {"isRunning", AnimatorControllerParameterType.Bool}
};

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

AAnimatorControllerParameterType

Bint

Cfloat

Dstring

💡 Hint

Common Mistakes

Using primitive types like int or float instead of the enum.

Mixing types in the dictionary values.

The dictionary maps parameter names to their types using AnimatorControllerParameterType.

5fill in blank

hard

Fill all three blanks to set multiple Animator parameters correctly.

Unity

Animator animator = GetComponent<Animator>();
animator.[1]("jumpHeight", 2.5f);
animator.[2]("isGrounded", [3]);

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

ASetFloat

BSetBool

Ctrue

DSetTrigger

💡 Hint

Common Mistakes

Using SetTrigger for non-trigger parameters.

Passing incorrect value types to methods.

Use SetFloat for float parameters, SetBool for boolean parameters, and true as the boolean value.
