Question by Thunderturtle712 · Mar 09, 2014 at 10:05 PM · c#2dfloatreturnside-scrolling

Assets/Scripts/PlayerController.cs(32,49): error CS0126: An object of a type convertible to `float' is required for the return statement

Can someone please tell me what this means?

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent(typeof(PlayerPhysics))]
 public class PlayerController : MonoBehaviour {
 
 
     public float speed = 8;
     public float acceleration = 12;
 
     private float currentSpeed;
     private float targetSpeed;
     private Vector2 amountToMove;
 
     private PlayerPhysics playerphysics;
 
     // Use this for initialization
     void Start () { 
         playerPhysics = GetComponent<PlayerPhysics>();
 
     
     }
     
     // Update is called once per frame
     void Update () {
         targetSpeed = Input.GetAxisRaw ("Horizontal") * speed;
         currentSpeed = IncrementTowards (currentSpeed, targetSpeed, acceleration);
     }
 
     private float IncrementTowards(float n, float target, float speed) {
         if (n == target) {
                         return; // this is the line it says
                 } else {
                         float dir = Mathf.Sign (target - n);
                         n += Time.deltaTime * dir;
                         return (dir == Mathf.Sign (target - n)) ? n : target;
                 }
         }
 }

You are missing a ';' on line 15. I imagine that your error was on line 18. When you see an error that doesn't make sense, the previous code line in the file is often the culprit.

In the future, close out the old question and open a new question. Editing an old/answered question to be a new question is confusing for anyone who is search for answers among the questions.

Your function IncrementTowards() returns a float, so any return statement needs to return a float value. I expect that line 32 should be:

  return 0.0;
