Why is my raycast projecting from the middle instead of the bottom?
I'm making a 2d platformer for school and I found this script for jumping but for some reason when I use it my raycast doesn't from the bottom.
public class Player : MonoBehaviour { private Rigidbody2D rb; private bool CanJump = true; [SerializeField] private float MovementSpeed; [SerializeField] private float JumpSpeed;
[SerializeField] private float RayLength;
[SerializeField] private float RayPositionOffset;
Vector3 RayPositionCenter;
Vector3 RayPositionLeft;
Vector3 RayPositionRight;
RaycastHit2D[] GroundHitsCenter;
RaycastHit2D[] GroundHitsLeft;
RaycastHit2D[] GroundHitsRight;
RaycastHit2D[][] AllRaycastHits = new RaycastHit2D[3][];
private void Awake()
{
rb = GetComponent<Rigidbody2D>();
}
private void Update()
{
Movement();
Jump();
}
private void Jump()
{
RayPositionCenter = transform.position + new Vector3(0, RayLength * .5f, 0);
RayPositionLeft = transform.position + new Vector3(-RayPositionOffset, RayLength * .5f, 0);
RayPositionRight = transform.position + new Vector3(RayPositionOffset, RayLength * .5f, 0);
GroundHitsCenter = Physics2D.RaycastAll(RayPositionCenter, -Vector2.up, RayLength);
GroundHitsLeft = Physics2D.RaycastAll(RayPositionLeft, -Vector2.up, RayLength);
GroundHitsRight = Physics2D.RaycastAll(RayPositionRight, -Vector2.up, RayLength);
AllRaycastHits[0] = GroundHitsCenter;
AllRaycastHits[1] = GroundHitsLeft;
AllRaycastHits[2] = GroundHitsRight;
CanJump = GroundCheck(AllRaycastHits);
Debug.DrawRay(RayPositionCenter, -Vector2.up * RayLength, Color.red);
Debug.DrawRay(RayPositionLeft, -Vector2.up * RayLength, Color.red);
Debug.DrawRay(RayPositionRight, -Vector2.up * RayLength, Color.red);
}
private bool GroundCheck(RaycastHit2D[][] GroundHits)
{
foreach (RaycastHit2D[] HitList in GroundHits)
{
foreach (RaycastHit2D hit in HitList)
{
if (hit.collider != null)
{
if (hit.collider.tag != "BoxCollider2D")
{
return true;
}
}
}
}
return false;
}
private void Movement()
{
if (Input.GetAxisRaw("Horizontal") > 0)
{
rb.velocity = new Vector2(MovementSpeed * Time.fixedDeltaTime, rb.velocity.y);
}
else if (Input.GetAxisRaw("Horizontal") < 0)
{
rb.velocity = new Vector2(-MovementSpeed * Time.fixedDeltaTime, rb.velocity.y);
}
else
{
rb.velocity = new Vector2(0, rb.velocity.y);
}
if (Input.GetKey(KeyCode.Space) && CanJump)
{
rb.velocity = new Vector2(rb.velocity.x, 0);
rb.velocity = new Vector2(rb.velocity.x, JumpSpeed);
}
}
}
