c#

I'm getting an error for the following chunk of code

public void FlipCard(Sprite startImage, Sprite endImage, int cardIndex) { StopCoroutine (Flip(startImage, endImage, cardIndex)); StartCoroutine (Flip(startImage, endImage, cardIndex)); }

Error is Argument 1: cannot convert from 'System.Collections.IEnumerable' to'System.Collections.IEnumerable'

Here's the who java class:

using System.Collections; using System; using System.Collections.Generic; using UnityEngine;

public class CardFlipper : MonoBehaviour { SpriteRenderer spriteRenderer; CardModel model;

public AnimationCurve scaleCurve; public float duration = 0.5f;

void Awake() { spriteRenderer = GetComponent(); model = GetComponent(); }

public void FlipCard(Sprite startImage, Sprite endImage, int cardIndex) { StopCoroutine (Flip(startImage, endImage, cardIndex)); StartCoroutine (Flip(startImage, endImage, cardIndex)); }

IEnumerable Flip(Sprite startImage, Sprite endImage, int cardIndex) { spriteRenderer.sprite = startImage;

float time = 0f; while (time <= 1f) { float scale = scaleCurve.Evaluate(time); time = time + Time.deltaTime / duration;

Vector3 localScale = transform.localScale; localScale.x = scale; transform.localScale = localScale;

if (time >= 0.5f) { spriteRenderer.sprite = endImage; }

yield return new WaitForFixedUpdate(); }

if (cardIndex == -1) { model.ToggleFace(false); } else { model.cardIndex = cardIndex; model.ToggleFace(true); } } }
