Shake Camera Add-On

[jgiroux]

Shake Camera Effect is always a welcome addition.

create a new c# script and call it "CameraShakeAddOn" (without the quotes).

open up that script and remove everything in there. copy and paste the below code. then save/compile/build.

using UnityEngine;
using System.Collections;
using Invector.CharacterController;
using Invector;
// simple script addon for InvectorCamera to allow screenshakes
// feel free to use as is or edited

public class CameraShakeAddOn : MonoBehaviour
{
   private Vector3 MainCamera_OriginalPosition;
   private Quaternion MainCamera_OriginalRotation;
   private float MainCamera_ShakeStrength;
   //public variables
   public vThirdPersonController myController; // link thirdPersonController //
   public float Intensity = 0.02f; // intensity of CameraShake
   public float DecayTime = 0.001f; // how long it takes camera to return to normal
   public bool ShakeCamera; // a easy public bool to trigger when to shake camera

   public void Update()
   {
       if (myController != null) // if controller is not active ignore
       {
           if (myController.GetComponent<vThirdPersonMotor>().hud.damaged == true)
           {
               ShakeCamera = true;  
           }
       }
           if (ShakeCamera == true)
           {
               Shake();
               ShakeCamera = false;
           }

           if (MainCamera_ShakeStrength > 0)
           {
               transform.position = MainCamera_OriginalPosition + Random.insideUnitSphere * MainCamera_ShakeStrength;
               transform.rotation = new Quaternion
               (
               MainCamera_OriginalRotation.x + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f,
               MainCamera_OriginalRotation.y + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f,
               MainCamera_OriginalRotation.z + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f,
               MainCamera_OriginalRotation.w + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f
               );
               MainCamera_ShakeStrength -= DecayTime;
           }
       
   }


  private void Shake() // function to shake camera
      {
       MainCamera_OriginalPosition = transform.position;
       MainCamera_OriginalRotation = transform.rotation;
       MainCamera_ShakeStrength = Intensity;
      }
}

Now add this script to your 3rdPersonCamera.

Steps.

1) Drag your Player Character into the "MyController" field in your Inspector

2) Adjust (if you like, however its set up with decent values) Intensity (how crazy the screen shakes)

3) Adjust (if you like, however its set up with decent values) DecayTime (how long it takes for camera to return to normal)

that's it. go try it out and have an enemy damage you, should trigger the screen shake.

of course, this script could be vastly improved upon, but its a start and works out of box, as it will check your Invectors Player for a Damage call and trigger the screen shake., but I made the ShakeScreen Boolean trigger a public variable, so you can call it from your own scripts to make further use of it.

also, this actually shakes screen on player damage, not on skills and attacks. but using the public bool as I mentioned you could easily access it a number of ways, just by setting MainCamera.GetComponent<CameraShakeAddOn>().ShakeCamera = true;

Saw the other thread, sounds amazing, since its third person, since the camera moves around, wouldn't you lose position, and possibly die? Just curious.

This is a nice one!

I tried implementing this but getting an error: "Assets/Add Ons/CameraShakeAddOn.cs(24,64): error CS1061: Type `Invector.CharacterController.vThirdPersonMotor' does not contain a definition for `hud' and no extension method `hud' of type `Invector.CharacterController.vThirdPersonMotor' could be found. Are you missing an assembly reference?"

[Invector]

A quickfix for that would be access the tpInput instead of the controller/motor

public vThirdPersonInput myController;
and replace the first if of the update:

if (myController != null && myController.hud != null)
       {
           if (myController.hud.damaged == true)            
               shakeCamera = true;            
       }

Got it working, thanks!

I tried but still haven't figure out how to make meleeManager to find the CameraShakeAddOn to enable the shake. Could anyone help?

I did this a little differently. I realized the script above doesn't continue to look at the current position of the camera each frame. So when you're moving it's trying to keep the camera where it was when it first got the camera's position. Also I liked using an IEnumerator and a shakeTime.

Mine doesn't look at whether the player's taking damage because I wanted it for when a projectile contacted the ground or the player.

But now we can make events on the player when he receives damage and just simply call this script from there like this.


Shake shakescript = Camera.main.gameObject.GetComponent<Shake>();
shakescript.ShakeCamera = true;




using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Shake : MonoBehaviour {
private Vector3 MainCamera_OriginalPosition;
private Quaternion MainCamera_OriginalRotation;
private float MainCamera_ShakeStrength;

private float startTime;
public float shakeTime = 1f;

public float Intensity = 0.02f; // intensity of CameraShake
public float DecayTime = 0.001f; // how long it takes camera to return to normal
public bool ShakeCamera; // a easy public bool to trigger when to shake camera

public void Update()
{
if (ShakeCamera == true)
{
CopyOriginalValues();
ShakeCamera = false;
startTime = Time.time;
StartCoroutine(DoShake());
}
}


   IEnumerator DoShake() {
while (Time.time - startTime < shakeTime) {
CopyOriginalValues();
transform.position = MainCamera_OriginalPosition + Random.insideUnitSphere * MainCamera_ShakeStrength;
transform.rotation = new Quaternion
(
MainCamera_OriginalRotation.x + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f,
MainCamera_OriginalRotation.y + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f,
MainCamera_OriginalRotation.z + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f,
MainCamera_OriginalRotation.w + Random.Range(-MainCamera_ShakeStrength, MainCamera_ShakeStrength) * .2f
);
MainCamera_ShakeStrength -= DecayTime;
yield return null;
}
}
private void CopyOriginalValues () // function to shake camera
{
MainCamera_OriginalPosition = transform.position;
MainCamera_OriginalRotation = transform.rotation;
MainCamera_ShakeStrength = Intensity;
}
}
