tried StartCoroutine but i get Argument 1: cannot convert from 'method group' to 'string'

don't really know unity script. In standard c# you could have something like Task.Delay() https://gamedevbeginner.com/how-to-delay-a-function-in-unity/ does this article help any?

You can also do this in Unity Unity supports async-await fine Please share the script. Looks like your syntax is not what it's supposed to be Or, you know, look up how Coroutines work since there's plenty of documentation

ElmishhOP•2y ago

The unity script document didnt work

FusedQyou•2y ago

Share the script We don't know what you did

StartCoroutine(colorChangeDelay); is not how you call a Coroutine

ElmishhOP•2y ago

is it not? how do you call it?

FusedQyou•2y ago

You need to invoke the method and internally IEnumerator-returning methods will invoke your code until a Yield instruction is met. In your case that's new WaitForSeconds(0.2f); Unity handles these when you use StartCoroutine So if you change that to StartCoroutine(colorChangeDelay()); it works

ElmishhOP•2y ago

so what should i do oh

FusedQyou•2y ago

Alternative:

var routine = colorChangeDelay();
StartCoroutine(routine);

var routine = colorChangeDelay();
StartCoroutine(routine);

ElmishhOP•2y ago

why is unity docs so overly complex well do you know why the color isnt changing? its static red for some reason

FusedQyou•2y ago

https://docs.unity3d.com/Manual/Coroutines.html This?

ElmishhOP•2y ago

https://docs.unity3d.com/ScriptReference/MonoBehaviour.StartCoroutine.html

FusedQyou•2y ago

private IEnumerator coroutine;
...

coroutine = WaitAndPrint(2.0f);
StartCoroutine(coroutine);

private IEnumerator coroutine;
...

coroutine = WaitAndPrint(2.0f);
StartCoroutine(coroutine);

They basically did the same thing as me You were probably confused by the extra parameter The docs are kinda shit here, yeah

ElmishhOP•2y ago

i cant even do that i cant do coroutine = WaitAndPrint or in my case colorChangeDelay =

FusedQyou•2y ago

It's WaitAndPrint() WaitAndPrint equals a delegate

ElmishhOP•2y ago

wdym

FusedQyou•2y ago

var routineInvoker = WaitAndPrint;
var routine = routineInvoker();
StartCoroutine(routine);

var routineInvoker = WaitAndPrint;
var routine = routineInvoker();
StartCoroutine(routine);

You would be saving a reference to the method Called a delegate

ElmishhOP•2y ago

well do you know why the color isnt changing? its static on red

FusedQyou•2y ago

Because you probably misunderstand the point of Coroutines

ElmishhOP•2y ago

im using them for delay

FusedQyou•2y ago

void Update()
        {
            if (isInizialized)
            {
                GorillaTagger.Instance.offlineVRRig.mainSkin.material.color = new Color(color1, color2, color3);
                if (color1 < 255 && color2 == 0 && color3 == 0) { color1 += 28.3333333333f; }
                if (color2 < 255 && color1 == 255) { color2 += 28.3333333333f; }
                if (color3 < 255 && color2 == 255) { color3 += 28.3333333333f; }

                if (color1 <= 255 && color1 > 0 && color3 == 255) { color1 -= 28.3333333333f; }
                if (color2 <= 255 && color2 > 9 && color1 == 0) { color2 -= 28.3333333333f; }
                if (color3 <= 255 && color3 > 9 && color2 == 0) { color3 -= 28.3333333333f; }
                StartCoroutine(colorChangeDelay());
            }
        }

void Update()
        {
            if (isInizialized)
            {
                GorillaTagger.Instance.offlineVRRig.mainSkin.material.color = new Color(color1, color2, color3);
                if (color1 < 255 && color2 == 0 && color3 == 0) { color1 += 28.3333333333f; }
                if (color2 < 255 && color1 == 255) { color2 += 28.3333333333f; }
                if (color3 < 255 && color2 == 255) { color3 += 28.3333333333f; }

                if (color1 <= 255 && color1 > 0 && color3 == 255) { color1 -= 28.3333333333f; }
                if (color2 <= 255 && color2 > 9 && color1 == 0) { color2 -= 28.3333333333f; }
                if (color3 <= 255 && color3 > 9 && color2 == 0) { color3 -= 28.3333333333f; }
                StartCoroutine(colorChangeDelay());
            }
        }

Do you expect this to delay the length that colorChangeDelay is waiting for?

ElmishhOP•2y ago

no i just want it to wait 0.2 seconds every times it runs through so its not too fast

FusedQyou•2y ago

A Coroutine sort of runs in the background, so there is no context that simulates a delay here

ElmishhOP•2y ago

FusedQyou•2y ago

It's hard to explain, but your Coroutine does have a delay This code in Update simply does not have that

ElmishhOP•2y ago

im confused now

FusedQyou•2y ago

What you can do, it put this code in a seperate Coroutine Give me a second

private _colorChangeWaitInstruction = new WaitForSeconds(0.2f);
void Start()
{
  StartCoroutine(ColorChangeRoutine());
}

IEnumerator ColorChangeRoutine()
{
  while(true)
  {
    if (!isInizialized)
    {
      // Wait a frame and check again.
      // This is important to do to avoid it locking up!
      yield return null;
      continue;
    }

    GorillaTagger.Instance.offlineVRRig.mainSkin.material.color = new Color(color1, color2, color3);
    if (color1 < 255 && color2 == 0 && color3 == 0) { color1 += 28.3333333333f; }
    if (color2 < 255 && color1 == 255) { color2 += 28.3333333333f; }
    if (color3 < 255 && color2 == 255) { color3 += 28.3333333333f; }

    if (color1 <= 255 && color1 > 0 && color3 == 255) { color1 -= 28.3333333333f; }
    if (color2 <= 255 && color2 > 9 && color1 == 0) { color2 -= 28.3333333333f; }
    if (color3 <= 255 && color3 > 9 && color2 == 0) { color3 -= 28.3333333333f; }
    yield return StartCoroutine(colorChangeDelay);
  }
}

IEnumerator ColorChangeDelay()
{
  yield return this._colorChangeWaitInstruction();
}

private _colorChangeWaitInstruction = new WaitForSeconds(0.2f);
void Start()
{
  StartCoroutine(ColorChangeRoutine());
}

IEnumerator ColorChangeRoutine()
{
  while(true)
  {
    if (!isInizialized)
    {
      // Wait a frame and check again.
      // This is important to do to avoid it locking up!
      yield return null;
      continue;
    }

    GorillaTagger.Instance.offlineVRRig.mainSkin.material.color = new Color(color1, color2, color3);
    if (color1 < 255 && color2 == 0 && color3 == 0) { color1 += 28.3333333333f; }
    if (color2 < 255 && color1 == 255) { color2 += 28.3333333333f; }
    if (color3 < 255 && color2 == 255) { color3 += 28.3333333333f; }

    if (color1 <= 255 && color1 > 0 && color3 == 255) { color1 -= 28.3333333333f; }
    if (color2 <= 255 && color2 > 9 && color1 == 0) { color2 -= 28.3333333333f; }
    if (color3 <= 255 && color3 > 9 && color2 == 0) { color3 -= 28.3333333333f; }
    yield return StartCoroutine(colorChangeDelay);
  }
}

IEnumerator ColorChangeDelay()
{
  yield return this._colorChangeWaitInstruction();
}

Something like this Notice you can use the delay routine in another Coroutine to simulate the delay You just can't do it where you did. These are methods that run on the main thread and they should never have a delay (because if they do, your program locks up), because this main thread does everything in your program (like rendering the screen).

ElmishhOP•2y ago

wut

FusedQyou•2y ago

Either way, try this

ElmishhOP•2y ago

im beyond confused

FusedQyou•2y ago

Your old code would run the code every single frame because it's in Update, and the delay didn't work either Unity is not going to wait for it to run

ElmishhOP•2y ago

line 1: 7 errors 6

FusedQyou•2y ago

You should put a Debug.Log message in the code to see when it runs, then you can see what it does. Like: Debug.Log("I finished running"); at the end of the method, below the StartCoroutine()

ElmishhOP•2y ago

FusedQyou•2y ago

What is the error?

ElmishhOP•2y ago

just put in line 1

FusedQyou•2y ago

Can you screenshot your editor?

ElmishhOP•2y ago

wdym

FusedQyou•2y ago

Screenshot your whole editor I want to see how it looks like

ElmishhOP•2y ago

the code?

FusedQyou•2y ago

Yes You probably did not configure it properly

ElmishhOP•2y ago

do you mean like this or something?

FusedQyou•2y ago

Small mistake in the code, change it to private WaitForSeconds _colorChangeWaitInstruction = new WaitForSeconds(0.2f); You also need to change yield return this._colorChangeWaitInstruction(); to yield return this._colorChangeWaitInstruction;

ElmishhOP•2y ago

its still just static red

ElmishhOP•2y ago

New_Text_Document.tx...

FusedQyou•2y ago

Then that has to do with your code Try the Debug.Log and see if it delays properly And you can also put your color values in it to see what it becomes It's most likely not what you expect it to be

ElmishhOP•2y ago

its stuck at 283.3333, 0, 0 which i dont know why i know why wait actually i dont know why no idea color1 reaches 255 and goes to 283.3333 and stays there it for some reason doesnt stop at 255 well it changed colors now it went from red->yellow->white->stuck which is still not correct

FusedQyou•2y ago

Hmmmm Well it increments one more time, so I'm guessing your if-statement is wrong Perhaps your color is not exactly 255, and it's just below it, causing it to increment once more? You're comparing floating points, which can be inaccurate You can always use a Clamp on the colors to clamp them between 0-255
