Missing a using directive or an assembly reference

Here is the script:
using UnityEngine;
using System.Collections;

[RequireComponent(typeof(PlayerPhysics))]
public class PlayerController : MonoBehaviour {

// Player Handling
public float gravity = 20;
public float speed = 8;
public float acceleration = 30;
public float jumpHeight = 12;

private float currentSpeed;
private float targetSpeed;
private Vector2 amountToMove;

private PlayerPhysics playerPhysics;


void Start () {
playerPhysics = GetComponent<PlayerPhysics>();
}

void Update () {
targetSpeed = Input.GetAxisRaw("Horizontal") * speed;
currentSpeed = IncrementTowards(currentSpeed, targetSpeed,acceleration);

if (playerPhysics.grounded) {
amountToMove.y = 0;

// Jump
if (Input.GetButtonDown("Jump")) {
amountToMove.y = jumpHeight;
}
}

amountToMove.x = currentSpeed;
amountToMove.y -= gravity * Time.deltaTime;
playerPhysics.Move(amountToMove * Time.deltaTime);
}

// Increase n towards target by speed
private float IncrementTowards(float n, float target, float a) {
if (n == target) {
return n;
}
else {
float dir = Mathf.Sign(target - n); // must n be increased or decreased to get closer to target
n += a * Time.deltaTime * dir;
return (dir == Mathf.Sign(target-n))? n: target; // if n has now passed target then return target, otherwise return n
}
}
}


I seriously don't get what's wrong. Been trying to figure this out for an hour.

 

What line is the error on?

 

17 apparently
"private PlayerPhysics playerPhysics;"

 

I don't think PlayerPhysics is a UnityEngine class. Where does it come from? Is it a script you made yourself?

 

No, I got in from this Youtube video:
http://www.youtube.com/watch?v=d3HEFiDFApI
I downloaded it from here: https://copy.com/EOYyPJKWQlUcDm2c/Scripts?download=1
Even though in the video he got no errors, seriously don't understand why I am.

 

The actual error says this: The type or namespace `PlayerPhysics' could not be found. Are you missing a using directive or an assembly reference?

 

Do you have the file "PlayerPhysics.cs" somewhere in the Assets folder? Missing that file could be a cause of your error.

 

I have it in my assets, according to the video, I made a new folder in assets titled "Scripts", and inserted that.

 

Yeah if it's missing I don't know why it's not complaining on:

Code (csharp):

1. [RequireComponent(typeof(PlayerPhysics))]

If the script is in your Assets folder somewhere try this:

1. Click on the "Assets" menu in Unity
2. Select "Refresh"

I'm not sure what else it could be!

 

That gave me 2 more errors

 

Is the old error still there? Are the new errors different?

 

Oh, I re-copied the scripts from the WordPad document. That seemed to do the trick, funny thing is, I originally copied the script from WordPad.

 

Awesome! I'm glad something fixed it! Good luck to you.

 

i have this same message but its 'touch' and 'IMEcompositionmode'. this app is the kart tutorial but it sorta happend out of no where, if you can answer asap that would be quite nice

 

i have the same problem but with rigidbody and it tells me that
'Rigidbody' does not contain a definition for 'Addforce' and no accessible extension method 'Addforce' accepting a first argument of type 'Rigidbody' could be found (are you missing a using directive or an assembly reference?)

 

Sometimes Visual Studio doesn't pick up the creation of the new script. Simply close and reopen VS.

 

, try using AddForce and not Addforce.

 

try AddForce

 

c# is cap sensitive so try that

 

I Didn't Get The Option To Insert Rigidbody
public Ridgidbody rb;
Getting This Error In This Line : error CS0246: The type or namespace name 'Ridgidbody' could not be found (are you missing a using directive or an assembly reference?)

 

looks like you typod "Rigidbody" in the code portion.

 

For me it was a capital letter mistake

 

Assets\move01.cs(5,12): error CS0246: The type or namespace name 'rigidbody' could not be found (are you missing a using directive or an assembly reference?)
can you please help me with this I could not understand what is the problem

 

My problem is that following IheartGameDev's tutorial I get this compiler message for the lines

Code (Csharp):

i'm try to fix my game after moveing it from my old computer to a new one
```
using UnityEngine;
using System.Collections;

public Transform spawnPoint;

public float timeBetweenWaves = 5f;
private float countdown = 2f;

public Text WaveCountDownText;

private int waveIndex = 0;

void Update()
{
if (countdown <= 0f)
{
StartCoroutine(SpawnWave());
countdown = timeBetweenWaves;
}

countdown -= Time.deltaTime;

WaveCountDownText.text = Mathf.Round(countdown).ToString();

}

IEnumerator SpawnWave()
{
waveIndex++;

for (int i = 0; i < waveIndex; i++)
{
SpawnEnemy();
yield return new WaitForSeconds(0.5f);
}
}

void SpawnEnemy()
{
Instantiate(enemyPrefab, spawnPoint.position, spawnPoint.rotation);
}

}

the erro messgae is

Seriously? Why do you try to hijack this 8 years old thread? Create your own thread. Also use code tags. The editor here on the forum has buttons up there, you know ^^. Apart from that in your code you have commented out the line

using UnityEngine.UI;

and the compiler complains that it can not find some UI related classes, ... mysterious. Those two things can't possibly be related

 

using Unity.Engine.UI has commented out
