Camera shake

Have a look at this thread

Hi @squareorb Thanks so much for the solution. It works like a charm!

I thought I'd never find a fix for getting a good Camera Shake. Just a quick one though.

Do you know of a method to somehow make only the X Y or Z Axis shake when you shake the position. I've tried converting everything to floats by using the .x/.y/.z parameters on the vector3's but it doesn't seem to work.

Any Suggestions? Thanks again!

Kind Regards,

I really liked this solution for what I'm working on so I thought I'd share the modifications I made. I added the ability to select from the inspector whether you just want to shake position, rotation or both. I also made the intensity and decay values public so they can be set from the inspector as well. And most importantly took the bulk of the code out of the update method and made it a coroutine. This keeps it from checking the shakeIntensity on every single frame whether shaking or not. Cheers!

 using UnityEngine; 
 using System.Collections;
 
 public class ShakeCamera : MonoBehaviour { 
 
     public bool shakePosition;
     public bool shakeRotation;
 
     public float shakeIntensity = 0.5f; 
     public float shakeDecay = 0.02f;
     
     private Vector3 OriginalPos;
     private Quaternion OriginalRot;
 
     private bool isShakeRunning = false;
 
     
     public void DoShake()
     {
         OriginalPos = transform.position;
         OriginalRot = transform.rotation;
 
         StartCoroutine ("ProcessShake");
     }
 
     IEnumerator ProcessShake()
     {
         if (!isShakeRunning) {
             isShakeRunning = true;
             float currentShakeIntensity = shakeIntensity;
 
             while (currentShakeIntensity > 0) {
                 if (shakePosition) {
                     transform.position = OriginalPos + Random.insideUnitSphere * currentShakeIntensity;
                 }
                 if (shakeRotation) {
                     transform.rotation = new Quaternion (OriginalRot.x + Random.Range (-currentShakeIntensity, currentShakeIntensity) * .2f,
                                                         OriginalRot.y + Random.Range (-currentShakeIntensity, currentShakeIntensity) * .2f,
                                                         OriginalRot.z + Random.Range (-currentShakeIntensity, currentShakeIntensity) * .2f,
                                                         OriginalRot.w + Random.Range (-currentShakeIntensity, currentShakeIntensity) * .2f);
                 }
                 currentShakeIntensity -= shakeDecay;
                 yield return null;
             }
 
             isShakeRunning = false;
         }
     }
 }

Thanks, this works perfectly!

For testing I added a test button which calls the DoShake function:

 using UnityEngine;
 using System.Collections;
 
 public class CameraShake : MonoBehaviour {
     
 
 public bool Shaking; 
 private float ShakeDecay;
 private float ShakeIntensity;    
 private Vector3 OriginalPos;
 private Quaternion OriginalRot;
 
 void Start()
 {
     Shaking = false;   
 }
 
 
 // Update is called once per frame
 void Update () 
 {
     if(ShakeIntensity > 0)
     {
         transform.position = OriginalPos + Random.insideUnitSphere * ShakeIntensity;
         transform.rotation = new Quaternion(OriginalRot.x + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f,
                                   OriginalRot.y + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f,
                                   OriginalRot.z + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f,
                                   OriginalRot.w + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f);
 
        ShakeIntensity -= ShakeDecay;
     }
     else if (Shaking)
     {
        Shaking = false;  
     }
 }
     
     
 void OnGUI() {
 
     if (GUI.Button(new Rect(10, 200, 50, 30), "Shake"))
         DoShake();
         Debug.Log("Shake");
 
 }        
         
 
         
         
     
 
 public void DoShake()
 {
     OriginalPos = transform.position;
     OriginalRot = transform.rotation;
 
     ShakeIntensity = 0.3f;
     ShakeDecay = 0.02f;
     Shaking = true;
 }    
     
     
 }
 

EDIT: mdjasper, thanks for coming up with the original solution!

 using UnityEngine;
 using System.Collections;
 
 public class ShakeCamera : MonoBehaviour 
 {
 public bool Shaking;
 private float ShakeDecay;
 private float ShakeIntensity;
 
 private Vector3 OriginalPos;
 private Quaternion OriginalRot;
 
 void Start()
 {
     Shaking = false;    
 }
 
 
 // Update is called once per frame
 void Update () 
 {
     if(ShakeIntensity > 0)
     {
         transform.position = OriginalPos + Random.insideUnitSphere * ShakeIntensity;
         transform.rotation = new Quaternion(OriginalRot.x + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f,
                                         OriginalRot.y + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f,
                                         OriginalRot.z + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f,
                                         OriginalRot.w + Random.Range(-ShakeIntensity, ShakeIntensity)*.2f);
         
         ShakeIntensity -= ShakeDecay;
     }
     else if (Shaking)
     {
         Shaking = false;    
     }
 }
 
 public void DoShake()
 {
     OriginalPos = transform.position;
     OriginalRot = transform.rotation;
     
     ShakeIntensity = 0.3f;
     ShakeDecay = 0.02f;
     Shaking = true;
 }

}
