Coroutines, while (true), infinite loops, and the Unity Editor

[high abyss]

I figured out that a coroutine I have (which was previously working fine) is now causing my Unity Editor to hang up when I press play. Here is the coroutine:

IEnumerator Controller()
    {
        // wait for pheromones to be assigned, access the first pheromone
        int currentPheromoneIndex = 0;
        while (pheromoneSequence.Length == 0)
        {
            yield return null;
        }
        currentPheromone = pheromoneSequence[currentPheromoneIndex];

        // begin obeying pheromones
        while (true);
        {
           // ... controller logic goes here ...
           yield return null;
        }
    }

But I do have other while(trues elsewhere in my code that aren't causing an issue? What's the deal?

Are you accidentally calling this function directly? Controller() instead of StartCoroutine(Controller())?

[high abyss]

void Start()
    {
        transform.position = colony.transform.position + new Vector3(0, 10, 0);
        antState = AntState.Idle;
        pheromoneState = PheromoneState.InProgress;

        StartCoroutine(Controller());
    }

No

[quiet flame]

If you comment out the StartCoroutine here, does it still crash?

It might be being called somewhere else too

[high abyss]

Oh, well, I said I was calling other coroutines with infinite loops without a problem, but that's actually not true anymore. The Controller is meant to call Continue, another infinite-loop coroutine that gets stopped also by the Controller

[high abyss]

Not in the ant script. I should probably make the Controller private?

[quiet flame]

Yeah, that'd at least let you know if you're accidentally calling it in a different script

[high abyss]

Which I'm all but certain I'm not :/

Weird, bc yesterday it was working until I started messing around with enums.

Well also I added something else, too

[quiet flame]

Probably. But it's a good idea to eliminate potential typos and accidents before digging deep into debugging.

[high abyss]

For sure

Works fine when the Controller isn't called. No surprise.

Works fine when the second loop of the Controller is commented out.

show the full code here - don't cut it out

[high abyss]

oh, it's currently commented

[primal hornet]

very easy for "... controller logic" to contain the problem

[high abyss]

and even so it hangs up

no, that is currently commented out

[primal hornet]

while (true);

youi have a semicolon there

delete it

[high abyss]

LOL OMG

[primal hornet]

that's your problem

[high abyss]

SORRY Y'ALL

[primal hornet]

your IDE should be giving you a squiggle too 😉

[quiet flame]

Oh

Dang, I shoulda noticed that

[high abyss]

using free VSCode, not getting squiggles >.>

lol thanks champs

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

• VS Code*
• JetBrains Rider
• Other/None

*VS Code's debugger plugin is unsupported.
We recommend using VS or Rider instead.

You can get squiggles with vscode, and should configure it

nice thanks!!
