Bloom and color grading in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable the Bloom effect on the Volume component.

Unity

var volume = GetComponent<Volume>();
if (volume.profile.TryGet(out Bloom bloom)) {
    bloom.intensity.overrideState = [1];
}

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

Dfalse

💡 Hint

Common Mistakes

Using 'false' disables the effect.

Using 'null' causes a compile error.

Using 'enabled' is not a valid boolean value.

Setting bloom.intensity.overrideState to true enables the Bloom effect.

2fill in blank

medium

Complete the code to set the intensity of the Bloom effect to 1.5.

Unity

var volume = GetComponent<Volume>();
if (volume.profile.TryGet(out Bloom bloom)) {
    bloom.intensity.value = [1];
}

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

A1.5f

B0.5f

C2.0f

D1

💡 Hint

Common Mistakes

Using integer 1 instead of float 1.5f.

Using 0.5f sets intensity too low.

Using 2.0f sets intensity higher than requested.

Setting bloom.intensity.value to 1.5f adjusts the bloom intensity to 1.5.

3fill in blank

hard

Fix the error in the code to properly set the color filter in Color Adjustments.

Unity

var volume = GetComponent<Volume>();
if (volume.profile.TryGet(out ColorAdjustments colorAdjustments)) {
    colorAdjustments.colorFilter.value = [1];
}

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

AColor(1, 0, 0)

BColor.red

C"red"

Dnew Color(1, 0, 0)

💡 Hint

Common Mistakes

Using 'Color(1, 0, 0)' without 'new' keyword causes error.

Using string '"red"' is invalid for Color type.

The colorFilter.value expects a Color object. new Color(1, 0, 0) correctly creates a red color.

4fill in blank

hard

Fill both blanks to create a VolumeProfile and add Bloom and Color Adjustments effects.

Unity

var profile = ScriptableObject.CreateInstance<VolumeProfile>();
profile.[1](out Bloom bloom);
profile.[2](out ColorAdjustments colorAdjustments);

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

BAdd

CRemove

DGetComponent

💡 Hint

Common Mistakes

Using TryGet instead of Add does not add new effects.

Using Remove deletes effects instead of adding.

Using GetComponent is invalid on VolumeProfile.

Use Add to add effects like Bloom and Color Adjustments to the VolumeProfile.

5fill in blank

hard

Fill all three blanks to set up a Volume component with a profile and enable Bloom with intensity 2.0.

Unity

var volume = gameObject.AddComponent<Volume>();
volume.isGlobal = [1];
volume.profile = [2];
if (volume.profile.TryGet(out Bloom bloom)) {
    bloom.intensity.overrideState = true;
    bloom.intensity.value = [3];
}

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

Afalse

Btrue

Cprofile

D2.0f

Attempts:

💡 Hint

Common Mistakes

Setting isGlobal to false limits effect to local area.

Assigning null or wrong variable to volume.profile causes errors.

Using integer 2 instead of float 2.0f for intensity.

Set isGlobal to true for global effect, assign the profile to the volume, and set bloom intensity to 2.0f.
