Emission and shape modules in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable the emission module of a ParticleSystem.

Unity

var emission = particleSystem.emission;
emission.[1] = true;

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

BrateOverTime

Cenabled

Dshape

💡 Hint

Common Mistakes

Using 'playOnAwake' which belongs to the main ParticleSystem, not emission.

Trying to set 'rateOverTime' to true, but it's a numeric value.

The enabled property turns the emission module on or off.

medium

Complete the code to set the emission rate over time to 10 particles per second.

Unity

var emission = particleSystem.emission;
emission.rateOverTime = [1]f;

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

C0

D10

💡 Hint

Common Mistakes

Using 0 which stops emission.

Using 5 or 20 which are incorrect rates for this task.

The rateOverTime property controls how many particles are emitted each second. Setting it to 10 means 10 particles per second.

3fill in blank

hard

Fix the error in the code to set the shape module's angle to 25 degrees.

Unity

var shape = particleSystem.[1];
shape.angle = 25f;

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

Aemission

Bshape

Crenderer

Dmain

💡 Hint

Common Mistakes

Using 'emission' instead of 'shape' which does not have an angle property.

Using 'renderer' which is unrelated here.

The shape module controls the shape of the particle emission. Access it via particleSystem.shape.

4fill in blank

hard

Fill both blanks to set the shape module's radius to 3 and enable it.

Unity

var shape = particleSystem.[1];
shape.[2] = 3f;

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

Ashape

Bemission

Cradius

Denabled

💡 Hint

Common Mistakes

Using 'emission' instead of 'shape' for the module.

Trying to set 'enabled' to 3 which is invalid.

First, access the shape module. Then set its radius property to 3.

5fill in blank

hard

Fill all three blanks to enable emission, set rate over time to 15, and set shape angle to 45.

Unity

var emission = particleSystem.emission;
emission.[1] = true;
emission.rateOverTime = [2]f;
var shape = particleSystem.[3];
shape.angle = 45f;

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

💡 Hint

Common Mistakes

Confusing 'rateOverTime' as a boolean property.

Using 'emission' instead of 'shape' for the last blank.

Enable emission by setting enabled to true, set rateOverTime to 15, and access the shape module to set its angle.
