💡 Hint

Common Mistakes

Using Stop() instead of Play() will prevent the effect from showing.

The Play() method starts the particle system, which is needed to show the fire effect.

💡 Hint

Common Mistakes

Trying to set rate directly causes errors because it's inside the emission module.

The rateOverTime property controls how many particles are emitted per second, which changes the smoke density.

💡 Hint

Common Mistakes

Using emission or shape modules will cause errors when setting startColor.

The main module controls main settings like start color. Accessing main is required to change startColor.

💡 Hint

Common Mistakes

Using Pause() instead of Stop() will only pause the effect, not stop it.

First, Play() starts the sparkle effect. Then, Stop() stops it when needed.

5fill in blank

Fill all three blanks to create a dictionary of effects with their names and play the fire effect.

Unity

var effects = new Dictionary<string, ParticleSystem> {
    {"fire", [1],
    {"smoke", [2],
    {"sparkle", [3]
};
effects["fire"].Play();

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

💡 Hint

Common Mistakes

Using an undefined variable like particleEffect will cause errors.

Each dictionary entry uses the correct ParticleSystem variable for fire, smoke, and sparkle effects.
