The PowerUp script provides functionality for collectible power-ups that temporarily affect the speed of the fire effect in Fuse Runner. There are two types of power-ups: Slow and Speed, each altering the fire’s movement for a short duration. The script plays a sound and particle effect upon collection, then destroys itself after the effect is applied.
Power-ups are a strategic gameplay element that rewards precision pathing and timing.
PowerUpNamespace: global
Inherits from: MonoBehaviour
PowerUpTypeDefines the type of speed-altering effect:
Slow: Reduces fire speed by 50%Speed: Increases fire speed by 150%
PowerUpType powerUpTypeSpecifies whether the power-up is a Slow or Speed modifier. Set via Inspector.
float effectDuration = 3fDetermines how long the power-up effect lasts in seconds.
AudioClip powerUpAudioClipAudio clip to be played when the power-up is activated.
ParticleSystem powerUpEffectVisual effect that plays when the power-up is triggered.
AudioSource powerUpAudioSourceHandles playback of the power-up’s sound effect.
void Awake()Initializes required component references: ParticleSystem and AudioSource.
void OnTriggerEnter2D(Collider2D other)Detects when the fire effect collides with the power-up and applies the appropriate speed modification.
FireEffectMover on the colliding object.ApplySpeedModifier() with values based on powerUpType.
void PlayPowerUpEffect()Plays the particle and sound effects associated with the power-up.
IEnumerator DestroyAfterEffect(float duration)Waits for the effect duration (based on audio clip length) before destroying the power-up GameObject.
duration: Time in seconds before self-destruction.
To create a power-up in a level:
GameObject with a 2D trigger collider.PowerUp.cs, an AudioSource, and a ParticleSystem.powerUpType in the Inspector.// Example Setup
powerUpType = PowerUp.PowerUpType.Speed;
effectDuration = 3f;
Rigidbody2D (set to Kinematic) and a Collider2D set as trigger.
