First person controller. rigidbody hides inherited member Error

Hi I am getting this 'First person controller. rigidbody hides inherited member UnityEngine.Component.rigidbody' Use the keyword if hiding was intended' message all of a sudden when my other scripts were working fine, What is wrong and how do I fix this?

 

You left out the keyword it was telling you to use ('new'). That's important if you want to actually fix the problem.

So, UnityEngine.Component (from which MonoBehaviour is derived, so your script is too) has a "rigidbody" member. Your script inherits that. It's not a useful member anymore, since all it does is cause the compiler to complain that this has been removed and offer to update your script, but it's there nonetheless.

Now you've gone and created a "rigidbody" member in your script. So we have the same identifier defined in two places in the inheritance chain: in your script, and in Component. This is known as "hiding" (your property hides the inherited one). Property or method hiding makes C# feel all squirmy and uncomfortable, because it thinks it's likely to lead to errors. So it complains (emits a warning) about it.

You can tell it to shut up and deal by simply adding the "new" keyword (as the error message says) in front of your own rigidbody property.

 

[Q Thank you Joe so the (new) instructions are in the brackets? Thanks I will try them out and hopefully they work

 

A better way would be to simply rename your member to something other then rigidbody.

There is a reason the compiler gets iffy about hiding members. It can and does lead to unusual bugs.

 

Thank you I trie what you said and it worked however I am getting a "Can't add script because script class can't be found" error

 

It's always helpful to post the exact error you get. A paraphrasing of the error may easily be misunderstood.

In this case, I think what you got is the error that occurs when the name of the script file doesn't match the name of the actual class. Please check that the class name (after "class" in the source code) matches the file name.

 

using UnityEngine;
using System.Collections;

[RequireComponent (typeof (GravityBody))]
public class FirstPersonHoverTank : MonoBehaviour {

// public vars
public float mouseSensitivityX = 250;
public float mouseSensitivityY = 250;
public float hoverSpeed = 20;
public float jumpForce = 1000f;
public float hoverForce = 65f;
public float hoverHeight = 3.5f;
public LayerMask groundedMask;

// System vars
bool grounded;
Vector3 moveAmount;
Vector3 smoothMoveVelocity;
float verticalLookRotation;
Transform cameraTransform;
Rigidbody Hovertank ;




void Awake() {
Screen.lockCursor = true;
cameraTransform = Camera.main.transform;
Hovertank = GetComponent<Rigidbody> ();
}

void Update() {

// Look rotation:
transform.Rotate(Vector3.up * Input.GetAxis("Mouse X") * mouseSensitivityX * Time.deltaTime);
verticalLookRotation += Input.GetAxis("Mouse Y") * mouseSensitivityY * Time.deltaTime;
verticalLookRotation = Mathf.Clamp(verticalLookRotation,-60,60);
cameraTransform.localEulerAngles = Vector3.left * verticalLookRotation;

// Calculate movement:
float inputX = Input.GetAxisRaw("Horizontal");
float inputY = Input.GetAxisRaw("Vertical");

Vector3 moveDir = new Vector3(inputX,0, inputY).normalized;
Vector3 targetMoveAmount = moveDir * hoverSpeed;
moveAmount = Vector3.SmoothDamp(moveAmount,targetMoveAmount,ref smoothMoveVelocity,.15f);

// Jump
if (Input.GetButtonDown("Jump")) {
if (grounded) {
Hovertank.AddForce(transform.up * jumpForce);
}
}

// Grounded check
Ray ray = new Ray(transform.position, -transform.up);
RaycastHit hit;

if (Physics.Raycast(ray, out hit, 1 + .1f, groundedMask)) {
grounded = true;
}
else {
grounded = false;
}

}

void FixedUpdate() {
// Apply movement to rigidbody
Vector3 localMove = transform.TransformDirection(moveAmount) * Time.fixedDeltaTime;
Hovertank.MovePosition(Hovertank.position + localMove);
}
}

 

OK I hope that was OK and I will do what you suggest thank you

 

This was super helpful! I got the error while running through the "Ruby's 2D Adventure" tutorial, and they don't address how to resolve it (I don't believe). They mention that your running over an old member we won't need, but the error is never mentioned.
In the future, I will just use a different name. For the tutorial, however, I will just use the "new" keyword so my script matches the tutorial script.
Thanks ya'll!

 

wait im sorry where did you put the "new"? I'm having the same problem in the Ruby tutorial. its not breaking anything but its just annoying to look at lol

 

You can't name your Rigidbody "rigidbody" because it hides the legacy "rigidbody" variable name.
simply name it "rgdbody" or whatever.

OR in the variable declaration:
private new Rigidbody rigidbody;

 

Please i a new here and working on a tutorial i came across online and i had same error. i am as new to c# as new to Unity 2D game development. this is y code and the error message

"Assets\Scripts\TapController.cs(12,17): warning CS0108: 'TapController.rigidbody' hides inherited member 'Component.rigidbody'. Use the new keyword if hiding was intended."

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

[RequireComponent(typeof(Rigidbody2D))]
public class TapController : MonoBehaviour {

public float tapForce = 10;
public float tiltSmooth = 5;
public Vector3 startPos;

Rigidbody2D rigidbody;
Quaternion downRotation;
Quaternion forwardRotation;

void Start(){

rigidbody = GetComponent<Rigidbody2D>();
downRotation = Quaternion.Euler(0,0,-90);
forwardRotation = Quaternion.Euler(0,0,35);

}

void Update(){
if (Input.GetMouseButtonDown(0)){
transform.rotation = forwardRotation;
rigidbody.AddForce(Vector2.up * tapForce, ForceMode2D.Force);
}

transform.rotation = Quaternion.Lerp(transform.rotation, downRotation, tiltSmooth * Time.deltaTime);
}

void OnTriggerEnter2D(Collider2D col) {
if (col.gameObject.tag == "ScoreZone"){
//register a score event
//play a sound
}

if (col.gameObject.tag == "DeadZone"){
rigidbody.simulated = false;
//register a dead event
//play a sound


}

}

}


Please i need help soonest.

Thanks anyone

 

You know if you read mine and JoeStrouts posts up the chain you would have your solution.

Either use 'new' to hide the variable, or change the name of the variable to something other than rigidbody.

 

@Kiwasi: Please can you post an example on how to use the 'new' keyword to hide the variable? Thanks with expectation.

 

@Kiwasi : Thanks a lot for your assistance. it worked.
