Heal reset Unity C#

I implemented healing into my Unity project and have a timer for when the player can heal and I want the timer to reset every time the player takes damage but I can't seem to get it to work.. here is my code:
private void HealthRegen()
{
timer += Time.deltaTime;
if (timer > timeToHeal)
{
StartCoroutine(HealthRegenCo());
}
if (damaged == true)
{
timer = 0f;
}
}
private void SetHealth(float value)
{
currentHealth = Mathf.Clamp(value, 0f, 100f);
healthbar.value = currentHealth;
}
private IEnumerator HealthRegenCo()
{
while (enabled)
{
yield return new WaitForSeconds(0.1f);
SetHealth(currentHealth + healAmount);
Save();
}
}

I see what happened here, let me descriptively explain what your code does.
I assume that HealthReign() is called in Update(), and the timer is increasing. When the timer goes above timeToHeal, the coroutine is started. If damage is set to true, timer is set to 0. When the timer goes above timeToHeal, the code inside else if block doesn't get called at all due to it being an else if. Code inside else if is only read when the condition in the if statement is false.
Fix, don't use else if, just use another if
private void HealthRegen()
{
timer += Time.deltaTime;
if (timer > timeToHeal)
{
StartCoroutine(HealthRegenCo());
}
if (damaged == true)
{
timer = 0f;
}
}

Time.deltaTime <-- this is working by Update() , so you can count time by your coroutine. like this.
private void HealthRegen()
{
StartCoroutine(HealthRegenCo());
}
private void SetHealth(float value)
{
currentHealth = Mathf.Clamp(value, 0f, 100f);
healthbar.value = currentHealth;
}
private IEnumerator HealthRegenCo()
{
while (enabled)
{
yield return new WaitForSeconds(0.1f);
timer += 0.1f;
SetHealth(currentHealth + healAmount);
Save();
if(timer > timeToHeal)
{
yield break;
}
}
}
//------------------------ I saw your question yestday , so I think like this is simply , and you can use "HealthOpen" to open or close health.
float time = 0;
public bool HealthOpen = false;
private void Update()
{
if(HealthOpen)
{
time += Time.detlaTime;
if(time > 0.1f)
{
time = 0;
setHeal(currentheal + heal);
}
if(currentheal >= 100)
{
HealthOpen = false;
}
}
}

Why I'm getting MissingReferenceException exception when starting the coroutine over and over again?

}
Inside the Update() when I press the R key it's destroying the Instantiated object and then Instantiate is again and start the coroutine again. The problem is when I press on the R key many times in a row after two times I'm getting MissingReferenceException exception in the editor :
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
GenerateWalls+d__12.MoveNext () (at Assets/Scripts/GenerateWalls.cs:81)
Line 81 is :
objectToScale.transform.localScale = Vector3.Lerp(startingScale, scaleTo, (elapsedTime / seconds));
The goal is to be able to generate the walls each time over again when pressing R it should stop the current coroutine and start over.
Maybe the problem is that it's in the middle of the coroutine and because the old coroutine didn't stop yet then the object is missing in the middle because I destroy it?
How then I should do it to be able to press R over and over again and it will start the coroutine over and over? Not to start multiple coroutines but to start each time the coroutine over again.

The solution is to add : StopCoroutine In the Update()
This is not the solution. I thought stopping the coroutine will stop also the while loop inside but it didn't. It seems that checking for null inside the while loop solved the problem :
public IEnumerator ScaleOverSeconds(GameObject objectToScale, Vector3 scaleTo, float seconds)
{
if (objectToScale != null)
{
float elapsedTime = 0;
Vector3 startingScale = objectToScale.transform.localScale;
while (elapsedTime < seconds)
{
if (objectToScale == null)
{
yield return null;
}
else
{
objectToScale.transform.localScale = Vector3.Lerp(startingScale, scaleTo, (elapsedTime / seconds));
elapsedTime += Time.deltaTime;
yield return new WaitForEndOfFrame();
}
}
objectToScale.transform.localScale = scaleTo;
scaleOver = true;
}
}

How can I respawn pickups in an array and through a coroutine?

I'm having difficulty getting my gold pickups to respawn after they've been destroyed on death. The idea is, if the player fails to pick up the 5 gold bars, activates a checkpoint, and dies, the current gold is destroyed and it resets once the screen has faded from black.
I currently have a Coroutine in my Health Manager that runs correctly if the player dies and resets them. I have a Gold Pickup script that destroys the gold if they haven't been picked up. I just can't seem to get them to re-instantiate. I've tried adding the instantiate code within the Health Manager's coroutine and within the Gold Pickup script. Nothing seems to work. If I'm not getting errors saying 'Array index is out of range' it's 'object reference not set to an instance of an object' etc.

In your DestroyGold() function, you instantiate the gold like this:
foreach (GameObject Gold in goldBarArray)
{
Destroy(Gold);
Instantiate(goldBarArray[5], goldRespawnPoint, goldStartPosition);
goldRespawnPoint = transform.position;
goldStartPosition = transform.rotation;
//healthManager.RespawnCo();
}
But transform.position and transform.rotation only get the position and rotation of the current object (i.e. whatever your script is attached to). So not only are you spawning all the gold in the same spot, it's spawning the gold at the location of the object that holds your script, not where you actually want it to go!
Without knowing much about the objects in your scene, here's what I can tell you: try creating a Transform[] to store the locations where you want to respawn the gold. Also, make sure you assign the goldRespawnPoint and goldStartPosition BEFORE you call Instantiate() in your foreach loop. Finally, just a general tip: you should never use variable == true or variable == false in an if statement. You can just use if(variable) or if(!variable), respectively. It will work just the same while being more readable and reducing the amount of code you need to write.
EDIT 1: In response to comments, I've added specific code examples for implementing these suggestions.
To start, you're probably getting the out of range error because of goldBarArray[5]. Since arrays start at index 0, you can only access up to element n-1 in a size n array. More on how to fix this in the next step.
Now for the Transform array. In the area where you declare your public variables (at the top of the script), add the line
public Transform[] spawnPoints;
Then, back in Unity you will be able to assign those spawn points in the Inspector.
EDIT 2: Additionally, in the foreach loop you're trying to instantiate one of the gold bars from the scene, but those are getting deleted with the Destroy(Gold); statement. Instead, you should be instantiating from the prefab which won't get destroyed. To do this, add
public GameObject goldPrefab;
up with the rest of your public variables. Then, in the Editor create a prefab by dragging one of the gold bars from the Hierarchy into your Assets folder. Finally, set that prefab to be the value of goldPrefab in the Inspector.
Now, you actually can clean up your foreach loop a little bit. You can get rid of the goldRespawnPoint and goldStartPosition lines because the respawn locations will be contained in the Transform array we just created. Again, without knowing how your scene is structured I've needed to just make an educated guess about what will work. Give this loop a try:
int spawnPointCounter = 0;
foreach(GameObject Gold in goldBarArray){
Destroy(Gold);
Transform currentSP = spawnPoints[spawnPointCounter];
Instantiate(goldPrefab, currentSP.position, currentSP.rotation);
spawnPointCounter++;
}

How to make a continuous rotation by changing this c# code

Im using Unity and have asked this on there forums however have not had any replies. Ive found this example from a plugin where I am trying to use the kinect to rotate an object using my right hand to rotate it right and the left to rotate left. I have managed to get the object to do this apart from it stops at each side of the object, but cant work out what part of the code is doing this.
Thanks

I understand you ask for help finding which parts are involved in the rotation.
As such, I looked through the scripts and noticed 2 sections in the PresentationScript.
This part in the Update() method. Based on the code and the comments that are part of it.
// spin the presentation
transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, spinSpeed * Time.deltaTime);
// check if transform reaches the target rotation. If yes - stop spinning
float deltaTargetX = Mathf.Abs(targetRotation.eulerAngles.x - transform.rotation.eulerAngles.x);
float deltaTargetY = Mathf.Abs(targetRotation.eulerAngles.y - transform.rotation.eulerAngles.y);
if(deltaTargetX < 1f && deltaTargetY < 1f)
{
// delay the slide
slideWaitUntil = Time.realtimeSinceStartup + slideChangeAfterDelay;
isSpinning = false;
}
This line in the Start() method is also involved.
targetRotation = transform.rotation;
A transform controls the position, scaling and as is relevant for this case, also the rotation of an object.

making an object move if a variable goes up or down

hi im trying to make a system where a variable controls the position of an object so that if the variable goes up then the Y position of the object will go up and if the variable goes down then the Y position of the object will go down.
I am trying to control the variable from a separate script but the value of the variable is not changing.
the variable script:
public class Money : MonoBehaviour {
public static float Flow;
public static float FlowPos;
// Use this for initialization
void Start () {
Flow = 50;
}
// Update is called once per frame
void Update () {
FlowPos = Flow/100;
print(Flow);
transform.position = new Vector3(10.56f,12 + FlowPos,1);
}
the script trying to change the variable:
using UnityEngine;
using System.Collections;
public class Barista01 : MonoBehaviour {
bool dragging = false;
bool CardActive = true;
void Start(){
}
void Update(){
if (transform.position.x > 11.5f && dragging == false){
GameControllerScript.Active = false;
this.Destroy(gameObject);
}
else if (transform.position.x < 4.5f && dragging == false){
GameControllerScript.Active = false;
Worker.Morale += 20;
Money.Flow -= 15;
this.Destroy(gameObject);
}
if (GameControllerScript.CardCall == 2 && CardActive == true){
CardActive = false;
Worker.Morale -= 20;
transform.position = new Vector3(8f, 6.89f, 9f);
}
}
void OnMouseDown(){
{
dragging = true;
}
}
void OnMouseUp(){
{
dragging = false;
}
}
}
edit: I put the plus, minus and eaquals symbols in the correct positions however the variables still do not change

You should correct these two lines:
Worker.Morale =+ 20;
Money.Flow =- 15;
to
Worker.Morale += 20;
Money.Flow -= 15;
