7.4 Creating Visual and Sound Feedback

Feedback enhances the player’s sense of interaction and achievement.

Step 1: Visual Effects

Use Unity’s Particle System for effects like explosions or glowing collectibles.

Trigger effects via scripts for specific events:

public ParticleSystem collectEffect;

void OnTriggerEnter(Collider other) {
    if (other.CompareTag("Collectible")) {
        collectEffect.Play();
        Destroy(other.gameObject);
    }
}

Step 2: Sound Effects

Add audio clips to objects (e.g., footsteps, item pickups, or damage sounds).

Play sound effects during events:

public AudioClip collectSound;
public AudioSource audioSource;

void OnTriggerEnter(Collider other) {
    if (other.CompareTag("Collectible")) {
        audioSource.PlayOneShot(collectSound);
        Destroy(other.gameObject);
    }
}

Step 3: Screen Effects

• Use Unity’s post-processing tools for effects like screen shake or color changes to indicate damage or power-ups.

Activity: Add visual and sound effects to your game to provide feedback for actions like collecting items, taking damage, or completing objectives.

Summary of Module 7
