2D Movement Problems
This is my first time using Unity and I was excited for the new Native 2D but after 8 hours and like 4 tutorials I still cant get my character to move. I keep getting errors. Any help would be appreciated, just trying to get my feet off the ground.
Here is my Player Controller movement script:
using UnityEngine;
using System.Collections;
public class PlayerControl : MonoBehaviour
{
[HideInInspector]
public bool facingRight = true; // For determining which way the player is currently facing.
[HideInInspector]
public bool jump = false; // Condition for whether the player should jump.
public float moveForce = 365f; // Amount of force added to move the player left and right.
public float maxSpeed = 5f; // The fastest the player can travel in the x axis.
public float jumpForce = 1000f; // Amount of force added when the player jumps.
private Transform groundCheck; // A position marking where to check if the player is grounded.
private bool grounded = false; // Whether or not the player is grounded.
private Animator anim; // Reference to the player's animator component.
void Awake()
{
// Setting up references.
groundCheck = transform.Find("groundCheck");
anim = GetComponent<Animator>();
}
void Update()
{
// The player is grounded if a linecast to the groundcheck position hits anything on the ground layer.
grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));
// If the jump button is pressed and the player is grounded then the player should jump.
if(Input.GetButtonDown("Jump") && grounded)
jump = true;
}
void FixedUpdate ()
{
// Cache the horizontal input.
float h = Input.GetAxis("Horizontal");
// The Speed animator parameter is set to the absolute value of the horizontal input.
anim.SetFloat("Speed", Mathf.Abs(h));
// If the player is changing direction (h has a different sign to velocity.x) or hasn't reached maxSpeed yet...
if(h * rigidbody2D.velocity.x < maxSpeed)
// ... add a force to the player.
rigidbody2D.AddForce(Vector2.right * h * moveForce);
// If the player's horizontal velocity is greater than the maxSpeed...
if(Mathf.Abs(rigidbody2D.velocity.x) > maxSpeed)
// ... set the player's velocity to the maxSpeed in the x axis.
rigidbody2D.velocity = new Vector2(Mathf.Sign(rigidbody2D.velocity.x) * maxSpeed, rigidbody2D.velocity.y);
// If the input is moving the player right and the player is facing left...
if(h > 0 && !facingRight)
// ... flip the player.
Flip();
// Otherwise if the input is moving the player left and the player is facing right...
else if(h < 0 && facingRight)
// ... flip the player.
Flip();
// If the player should jump...
if(jump)
{
// Set the Jump animator trigger parameter.
anim.SetTrigger("Jump");
// Add a vertical force to the player.
rigidbody2D.AddForce(new Vector2(0f, jumpForce));
// Make sure the player can't jump again until the jump conditions from Update are satisfied.
jump = false;
}
}
void Flip ()
{
// Switch the way the player is labelled as facing.
facingRight = !facingRight;
// Multiply the player's x local scale by -1.
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}
Could you post some of the error messages you're getting? That could help a lot. I'm a little sleepy and didn't find anything wrong. But it could be my lack of concentration right now. Or maybe the error is being caused by something else on your scene.

Make sure that you applied the script to your player.

Don't name your Class PlayerControl
. This is already defined in the global::
namespace. Rename it to e.g. PlayerController
. This should work.
