Making character jump

[mangohack]

hi everyone im trying to make my character jump by himself but i got some error

using UnityEngine; using System.Collections;
public class Enemy : MonoBehaviour {

public float speed = 4f;
public float jetPackSpeed = 0.3f;
public float jumpSpeed = 8f;
public float gravity = 10;

private Transform _Player; 
private CharacterController character;
private Transform tr;
private float vSpeed = 0f;
private bool jump = false;

void Start ()
{
	_Player = GameObject.FindGameObjectWithTag("Player").transform;
	character = GetComponent();
	tr = transform;
}

void Update ()
{	// find the vector enemy -> player
	Vector3 chaseDir = _Player.position - tr.position;
	chaseDir.y = 0; // let only the horizontal direction
	float distance = chaseDir.magnitude;  // get the distance
	if (distance <= 2)
		Debug.Log("Attacking Player");
	else
	{	// find the player direction
		Quaternion rot = Quaternion.LookRotation(chaseDir);
		// rotate to his direction
		tr.rotation = Quaternion.Slerp(tr.rotation, rot, Time.deltaTime * 4);
		if (character.isGrounded){ // if is grounded...
			vSpeed = 0;  // vertical speed  is zero
			if (jump){    // if should jump...
				vSpeed = jumpSpeed; // aplly jump speed
				jump = false; // only jump once!
			}
		} 
		else // but if lost ground, check if it's an abyss
		if (!Physics.Raycast(tr.position, -tr.up, 20f)){ // if no ground below
			vSpeed = jetPackSpeed;  // use jetpack
		}
		vSpeed -= gravity * Time.deltaTime; // apply gravity
		// calculate horizontal velocity vector
		chaseDir = chaseDir.normalized * speed;
		chaseDir.y += vSpeed; // include vertical speed
		// and move the enemy
		character.Move(chaseDir * Time.deltaTime);
	}
}

// if collided with some wall or block, jump
void OnControllerColliderHit(ControllerColliderHit hit){
	// only check lateral collisions
	if (Mathf.Abs(hit.normal.y) < 0.5){
		jump = true; // jump if collided laterally
	}
}

}

Change: character = GetComponent();

To: character = GetComponent();
