Languages available:

Question 1

What is the best description of how a particle system works in Unity? Select one answer.

Select only one

A particle system breaks down a complex mesh into its component vertices to simulate many moving parts and produce a visual effect.

A particle system renders many small images or meshes, called particles, to produce a visual effect.

A particle system shoots light through a complex lens, similar to a projector, to produce a visual effect.

A particle system generates individual pixels of varying sizes, each with a different material, to produce a visual effect.

Question 2

In the main module of the Particle System component, what does the Start Lifetime property determine? Select one answer.

Select only one

How many seconds an individual particle will exist before it disappears.

How many seconds the entire particle system will exist before it stops emitting particles.

How many frames it takes for an individual particle to fade into the scene.

How many frames the delay is before the particle system begins emitting particles.

Question 3

In the Particle System component, what does the Shape module control? Select one answer.

Select only one

The shape of an individual particle.

The volume that particles within a system can exist in – when particles leave this shape, they disappear.

The shape of the collider that particles cannot enter – if particles collide with this shape, they disappear.

The shape of the emitter that generates particles – particles can only be spawned within the defined shape.

Question 4

You’re trying to make a particle system that produces a steady stream of particles. However, you notice that there are large gaps in the emission of particles (see image below). What could be done to resolve these gaps? Select all answers that apply.

Select all correct answers

Decrease the Start Lifetime.

Increase the Start Speed.

Decrease the Rate Over Time.

Increase the Max Particles.

Question 5

To change the default particle system, which emits a constant stream of particles, into a single burst of particles, what would you do? Select one answer.

Select only one

Disable the Looping property.

Reduce the Max Particles.

Enable the Stop Action property.

Enable the Limit Velocity over Lifetime property.

Question 6

The particle system shown below is only emitting particles around the edge of the emitter. What property would you have to change to make particles emit from the whole volume of the emitter?

Select only one

In the Sub Emitters module, enable the Fill In Emitter Area property.

In the Shape module, change the Emit From property from Edge to Volume.

In the Emission module, set the Emission Area Percentage value to 1.0.

In the Shape module, change the Shape from Box to Cube.

Question 7

Which of the following are real modules within Unity’s Built-in Particle System? Select all correct answers.

Select all correct answers

The Sub Emitters module.

The Velocity over Lifetime module.

The Size over Lifetime module.

The Color over Lifetime module.

Question 8

What does the Color over Lifetime module in Unity's Built-in Particle System define?

Select only one

The gradual change of particle colors as they age and progress through their lifespan.

The transparency of particles based on their distance from the camera.

The overall brightness of the particles emitted by the system.

The random variation of colors applied to each individual particle.
