Hello and good afternoon, I am a 26 year old who is starting his journey with c# im currently on the Unity Engine trying to develop a video game. I was hoping someone might be able to point out where i went wrong with this character controller. I followed a tutorial and it still seems to not want to work. I keep getting an error CS514 if someone can help ide be very grateful!
C#:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CharacterController : MonoBehaviour
{
public float speed = 100.0f;
public float jumpForce = 350.0f;
public float airDrag = 0.8f;
public Transform bottomTransform;
private Rigidbody2D body;
private Animator animator;
private SpriteRenderer spriteRenderer;
private Vector2 currentVelocity;
private float previousPositionY;
private bool isOnGround;
// Start is called before the first frame update
void Start()
{
body = GetComponent<Rigidbody2D>();
animator = GetComponent<Animator>();
spriteRenderer = GetComponent<SpriteRenderer>();
}
// Update is called once per frame
void Update()
{
}
private void FixedUpdate()
{
Move();
HandleCollisions();
previousPositionY = transform.position.y;
}
private void Move()
{
float velocity = Input.GetAxis("Horizontal") * speed;
bool isJumping = Input.GetKey(KeyCode.Space);
animator.SetFloat("Speed", Mathf.Abs(velocity));
if (!isOnGround)
{
velocity *= airDrag;
}
// Horizontal Movement
body.velocity = Vector2.SmoothDamp(body.velocity, new Vector2(velocity, body.velocity.y), ref currentVelocity, 0.02f);
// Initiate Jump
if (isOnGround && isJumping)
{
animator.SetBool("IsJumping", true);
isOnGround = false;
body.AddForce(new Vector2(0, jumpForce));
}
// Cancel Jump
if (!isOnGround && !isJumping && body.velocity.y > 0.01f)
{
body.velocity = new Vector2(body.velocity.x, body.velocity.y * 0.95f);
}
if (velocity < 0) spriteRenderer.flipX = true; else if (velocity > 0)
spriteRenderer.flipX = false;
}
private void HandleCollisions()
{
bool wasOnGround = isOnGround;
isOnGround = false;
Collider2D[] colliders = Physics2D.OverlapCircleAll(bottomTransform.position, 0.6f);
foreach (var collider in colliders)
{
if (collider.gameObject != gameObject)
{
isOnGround = true;
if (!wasOnGround && previousPositionY > transform.position.y)
HandleLanding();
}
}
}
private void HandleLanding()
{
animator.SetBool("IsJumping", false);
}
}
