Keep getting error Assets/ScreenShake.cs(20,44): error CS0411: The type arguments for method `UnityEngine.Component.GetComponent()' cannot be inferred from the usage. Try specifying the type arguments explicitly

Hello. I am trying to build a shake screen script using one I found online. I keep getting the error "The type arguments for method `UnityEngine.Component.GetComponent()' cannot be inferred from the usage. Try specifying the type arguments explicitly" If anyone could see where that would be coming from I would greatly appreciate it! I have marked the line that gives the error. Thanks in advance!

using UnityEngine; using System.Collections;

public class ScreenShake : MonoBehaviour {

 //editor exposed variables
 public float ShakeAmount = 0.25f;
 public float DecreaseFactor = 1.0f;


 //class internal variables
 private new Camera camera;
 private Vector3 cameraPos;
 private float shake = 0.0f;

 void Awake(){

     //go and find the camera
     this.camera = (Camera)this.GetComponent();            ............error line..............

     if (this.camera == null) {
     
         //print an error
         Debug.Log ("CameraShake:Unable to find 'camera' component attached to GameObject");
     
     }
 
 }






 
 // Update is called once per frame
 void Update () {
             //public void Shake(float amount){}
             if (this.shake > 0.0f) {
                     //clamp the shake amount back to zero and reset the camera position to our chached value
                     this.shake = 0.0f;
                     this.camera.transform.localPosition = this.cameraPos;
     
             }
     }




 public void Shake(float amount){

         if(this.shake<=0.0f){

             this.cameraPos = this.camera.transform.position;

         }
         this.shake = amount;

     }
 }
