Player Control Animation

Unity Engine
1

Here are the problems:
1)
NullReferenceException: Object reference not set to an instance of an object
PlayerController.Update () (at Assets/Scripts/PlayerController.cs:30)
2)
‘Timothy Clever’ AnimationEvent ‘Movement’ has no receiver! Are you missing a component?

Here is the actual script:

usingUnityEngine;
usingSystem.Collections;

[RequireComponent(typeof(PlayerPhysics))]
publicclassPlayerController : MonoBehaviour {

//PlayerHandling
publicfloatgravity = 20;
publicfloatspeed = 8;
publicfloatacceleration = 45;
publicfloatjumpHeight = 12;

privatefloatcurrentSpeed;
privatefloattargetSpeed;
privateVector2amountToMove;

privatePlayerPhysicsplayerPhysics;

voidStart () {
playerPhysics = GetComponent();
}

voidUpdate () {

Movement();
}

voidMovement()
{
if(Input.GetKey (KeyCode.D))
{
transform.Translate(Vector2.right * 2f * Time.deltaTime);
transform.eulerAngles = newVector2(0, 0);
}
if(Input.GetKey (KeyCode.A))
{
transform.Translate(Vector2.right * 2f * Time.deltaTime);
transform.eulerAngles = newVector2(0, 180);
}

//Input
targetSpeed = Input.GetAxisRaw(“Horizontal”) * speed;
currentSpeed = IncrementTowards(currentSpeed, targetSpeed,acceleration);

if (playerPhysics.grounded) {
amountToMove.y = 0;

//Jump
if (Input.GetButtonDown(“Jump”)) {
amountToMove.y = jumpHeight;
}
}

amountToMove.x = currentSpeed;
amountToMove.y -= gravity * Time.deltaTime;
playerPhysics.Move(amountToMove * Time.deltaTime);
}

//Increasentowardstargetbyspeed
privatefloatIncrementTowards(floatn, floattarget, floata) {
if (n == target) {
returnn;
}
else {
floatdir = Mathf.Sign(target - n); //mustnbeincreasedordecreasedtogetclosertotarget
n += a * Time.deltaTime * dir;
return (dir == Mathf.Sign(target-n))? n: target; //ifnhasnowpassedtargetthenreturntarget, otherwisereturnn
}
}
}

can you go to the lines associated with the errors given? they will point to the lines the errors are associated with.

you may want to double check whether the PlayerPhysics component is actually attached to this game object. the errors tell me that the script detects no PlayerPhysics component you have, or some code is missing in that PlayerPhysics component.
