How do i call this Ienumerator?

I’m trying to call this Coroutine and its not working no matter what I do. It gives off a CS1503 and I have absolutely no clue how to fix it. I’ve tried numerus things and nothing has worked this far.

Here’s the code:

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

public class PlayerController : MonoBehaviour
{
    [Header("Movement Settings")]
    [SerializeField] float moveSpeed = 5f;
    [SerializeField] float rotationSpeed = 500f;
    [SerializeField] float jumpHeight = 5f;

    /* set radius for ground check */
    [Header("Ground Check Settings")]
    [SerializeField] float groundCheckRadius = 0.2f;
    [SerializeField] Vector3 groundCheckOffset;
    [SerializeField] LayerMask groundLayer;

    bool inAction;

    bool isGrounded;

    float ySpeed;
    Quaternion targetRotation;

    CameraController cameraController;
    Animator animator;
    CharacterController characterController;
    private void Awake()
    {
        cameraController =  Camera.main.GetComponent<CameraController>();
        animator = GetComponent<Animator>();
        characterController = GetComponent<CharacterController>();
    }
    private void Update()
    {
        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");

        float moveAmount = Mathf.Clamp01(Mathf.Abs(h) + Mathf.Abs(v));

        var moveInput = (new Vector3(h, 0, v)).normalized;

        var moveDir = cameraController.PlanarRotation * moveInput;

        var velocity = moveDir * moveSpeed;
        velocity.y = ySpeed;

        if(Input.GetButtonDown("Jump") && !inAction)
        {
            StartCoroutine(DoJumpAnimation());
            ySpeed = jumpHeight;
        }

        GroundCheck();
        if (isGrounded)
        {
            ySpeed = -0.5f;
        }
        else 
        {
            ySpeed += Physics.gravity.y * Time.deltaTime;
        }

        characterController.Move(velocity * Time.deltaTime);

        if (moveAmount > 0)
        {
            targetRotation = Quaternion.LookRotation(moveDir);
        }

        transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);

        animator.SetFloat("moveAmount", moveAmount, 0.5f, Time.deltaTime);
    }

    void GroundCheck()
    {
        isGrounded = Physics.CheckSphere(transform.TransformPoint(groundCheckOffset), groundCheckRadius, groundLayer); 
    }

    private void OnDrawGizmosSelected()
    {
        Gizmos.color = new Color(0, 0, 1, 0.5f);
        Gizmos.DrawSphere(transform.TransformPoint(groundCheckOffset), groundCheckRadius);
    }

    IEnumerable DoJumpAnimation ()
    {
        inAction = true;
        animator.CrossFade("Jump", 0.2f);
        yield return null;

        var animState = animator.GetNextAnimatorStateInfo(0);

        yield return new WaitForSeconds(animState.length);

        inAction = false;
    }
}

And heres the error in unity

Assets\Scripts\Controllers\PlayerController.cs(50,28): error CS1503: Argument 1: cannot convert from ‘System.Collections.IEnumerable’ to ‘string’

This is a 3d Character Movement script if that means anything. Trying to make a jump function with animation. So far jump works, but animation doesnt.

I think you should be able to look at the docs and see what you did wrong: Unity - Scripting API: Coroutine

3

I need the “coroutine = (coroutinename)” and then start that instead of it directly?

4

Your method is returning the wrong type.

5

Ok, how do i fix it to run the right type? (Also thank you btw dude, you’ve been my saving grace tonight.)

6

Just… update your method to return IEnumerator not IEnumerable. Read the docs, you can see that they all return IEnumerator.

ah ok, thank you again. Sorry for all the newbie questions
