Sub-emitters in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to add a sub-emitter to the main particle system.

Unity

var subEmitter = mainParticleSystem.subEmitters.[1]();

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

ANewSubEmitter

BCreateSubEmitter

CAddSubEmitter

DMakeSubEmitter

💡 Hint

Common Mistakes

Using a method name that does not exist like CreateSubEmitter.

Trying to instantiate sub-emitters directly without using the provided method.

The method AddSubEmitter() is used to add a sub-emitter to a particle system in Unity.

Complete the code to set the sub-emitter type to 'Birth'.

Unity

subEmitter.subEmitterType = ParticleSystemSubEmitterType.[1];

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

ADeath

BBirth

CCollision

DTrigger

💡 Hint

Common Mistakes

Confusing 'Death' with 'Birth' as the sub-emitter trigger.

Using a type that does not exist in the enum.

The sub-emitter type Birth triggers the sub-emitter when a particle is born.

3fill in blank

hard

Fix the error in the code to correctly access the sub-emitters count.

Unity

int count = mainParticleSystem.subEmitters.[1];

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

ACount

Bcount

CLength

DsubEmittersCount

Attempts:

💡 Hint

Common Mistakes

Using 'Length' which is not a property of subEmitters.

Using lowercase 'count' which is not defined.

The correct property to get the number of sub-emitters is Count.

4fill in blank

hard

Fill both blanks to correctly get the sub-emitter at index 0 and enable it.

Unity

var subEmitter = mainParticleSystem.subEmitters.[1](0);
subEmitter.[2] = true;

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

AGetSubEmitterSystem

Benabled

CSetSubEmitterSystem

DisActive

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'SetSubEmitterSystem' which does not exist.

Using 'isActive' instead of 'enabled' to enable the system.

GetSubEmitterSystem(0) gets the first sub-emitter system, and setting enabled to true activates it.

5fill in blank

hard

Fill all three blanks to create a sub-emitter triggered on particle death with a specific particle system.

Unity

mainParticleSystem.subEmitters.[1](deathParticleSystem, ParticleSystemSubEmitterType.[2], [3]);

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

AAddSubEmitter

BDeath

CEmitterProperties.InheritColor

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'Birth' instead of 'Death' for the trigger type.

Passing incorrect properties instead of 'EmitterProperties.InheritColor'.

AddSubEmitter adds the sub-emitter, Death sets the trigger type, and EmitterProperties.InheritColor sets the sub-emitter to inherit the color from the parent particles.
