Lesson 3.4 - Particles and Sound Effects

Customize an explosion particle

  1. From the Course Library > Particles, drag FX_Explosion_Smoke into the hierarchy, then use the Play / Restart / Stop buttons to preview it
  2. Play around with the settings to get your particle system the way you want it
  3. Make sure to uncheck the Play on Awake setting
  4. Drag the particle onto your player to make it a child object, then position it relative to the player ​

Play the particle on collision

  1. In PlayerController.cs, declare a new public ParticleSystem explosionParticle;
  2. In the Inspector, assign the explosion to the explosion particle variable
  3. In the if-statement where the player collides with an obstacle, call explosionParticle.Play();, then test and tweak the particle properties

Add a dirt splatter particle

  1. Drag FX_DirtSplatter as the Player’s child object, reposition it, rotate it, and edit its settings
  2. Declare a new public ParticleSystem dirtParticle;, then assign it in the Inspector
  3. Add dirtParticle.Stop(); when the player jumps or collides with an obstacle
  4. Add dirtParticle.Play(); when the player lands on the ground

Add music to the camera object

​
  1. Select the Main Camera object, then Add Component > Audio Source
  2. From Course Library > Sound, drag a music clip onto the AudioClip variable in the inspector
  3. Reduce the volume so it will be easier to hear sound effects
  4. Check the Loop checkbox

Declare variables for Audio Clips

  1. In PlayerController.cs, declare a new public AudioClip jumpSound; and a new public AudioClip crashSound;
  2. From Course Library > Sound, drag a clip onto each new sound variable in the inspector

Play Audio Clips on jump and crash

  1. Add an Audio Source component to the player
  2. Declare a new private AudioSource playerAudio; and initialize it as playerAudio = GetComponent<AudioSource>();
  3. Call playerAudio.PlayOneShot(jumpSound, 1.0f); when the character jumps
  4. Call playerAudio.PlayOneShot(crashSound, 1.0f); when the character crashes
