Camera Shaker Script:
using System.Collections;
using UnityEngine;
using UnityEngine.InputSystem;
public class CameraShaker : MonoBehaviour
{
[Range(0, 1)]
[SerializeField] private float DefaultRotationStrength = 0.15f;
[SerializeField] private float DefaultPositionStrength = 2f;
[SerializeField] private float DefaultDuration = 0.5f;
private void Update()
{
if (Keyboard.current.spaceKey.isPressed)
{
Shake(DefaultDuration, DefaultPositionStrength, DefaultRotationStrength);
}
}
public void Shake(float duration, float positionOffsetStrength, float rotationOffsetStrength)
{
StopAllCoroutines();
StartCoroutine(CameraShakeCoroutine(duration, positionOffsetStrength, rotationOffsetStrength));
}
private IEnumerator CameraShakeCoroutine(float duration, float positionOffsetStrength, float rotationOffsetStrength)
{
float elapsed = 0f;
float currentMagnitude = 1f;
while (elapsed [[Youtube doesn't want me putting a less than symbol here]] duration)
{
float x = (Random.value - 0.5f) * currentMagnitude * positionOffsetStrength;
float y = (Random.value - 0.5f) * currentMagnitude * positionOffsetStrength;
float lerpAmount = currentMagnitude * rotationOffsetStrength;
Vector3 lookAtVector = Vector3.Lerp(Vector3.forward, Random.insideUnitCircle, lerpAmount);
transform.localPosition = new Vector3(x, y, 0);
transform.localRotation = Quaternion.LookRotation(lookAtVector);
elapsed += Time.deltaTime;
currentMagnitude = (1 - (elapsed / duration)) * (1 - (elapsed / duration));
yield return null;
}
transform.localPosition = Vector3.zero;
transform.localRotation = Quaternion.identity;
}
}
