quiz game freeze

[keen granite]

^thread

[dense bolt]

okay okay

[keen granite]

can you show me this window?

[dense bolt]

how?

[keen granite]

screenshot it

[dense bolt]

oh wait

[keen granite]

on windows, Win + Shift + S will let you clip part of your screen and then paste it

quiz game freeze

[dense bolt]

uhhh its not frozen yet

wait up imma make it freezee

[keen granite]

ah, it broke in some random other thread

this won't be relevant, yeah

[dense bolt]

wait it breaks now

[keen granite]

hit Continue to let the editor resume

[dense bolt]

i'll press the pause?

[keen granite]

then make the game freeze and pause in VS

[dense bolt]

okay i did it

[keen granite]

you may need to switch the thread you're viewing if it paused on the wrong one again

[dense bolt]

i have this

[keen granite]

click on the Thread dropdown

what options does it give you?

[keen granite]

those are some great names lol

scroll up

[dense bolt]

i dont know that those means tbh

i didn't set up those

[keen granite]

scroll all the way up

they're all unity-internal stuff

[dense bolt]

i see

[keen granite]

wait, can you show me how you attached to unity?

[dense bolt]

i pressed that thing

attach to unity button

[keen granite]

okay, so that should be right

[dense bolt]

i'm reloading the editor

okay so what now?

[keen granite]

make sure that the editor is in Debug Mode, run the game, and Attach to Unity in VS

don't make the game freeze yet

[dense bolt]

i think the checker one if fucking it up tbh

wait up

[keen granite]

that bug icon should be green

[dense bolt]

okay okay

its compiling

but its yellow

after i attach it should be green right?

[keen granite]

oh, is it yellow?

[dense bolt]

its blue now

[keen granite]

i'm red-green colorblind lol

[dense bolt]

after i attach its blue

oh shit

[keen granite]

that sounds promising

did it behave better this time?

[dense bolt]

wait i'll try to press the buttons again

oh wait

i didnt pressed play

okay its still blu

[keen granite]

once you enter play mode, try pausing in VS

[dense bolt]

okay i'll pause now

[keen granite]

see if it actually has a main thread this time

[dense bolt]

its still frame not i module

[dense bolt]

yeah i'll just screenshot it

[keen granite]

hm, that's not very useful

tell you what -- i'm going to go set this up correctly on my PC and try debugging myself

what version of unity is this?

[dense bolt]

2022.2.5f1

[keen granite]

gotcha

[dense bolt]

is there a better way to do the not giving the prev asnwers?

if that's the problem i guess that's what should i replace

[keen granite]

I guess I'd just make a list of all things you haven't asked yet

[dense bolt]

i mean question

[keen granite]

and then remove things from the list as you ask them

[dense bolt]

uhhh sure

[keen granite]

i'm really curious what the problem is with the debugger tho

it's very useful for tracking down things that make the editor freeze/crash/instantly close

[dense bolt]

ohhh i see

yeah its been bugging me in the last 2 - 3 days with this error

but it works when i remove the popup of the panel

should i try it on my phone and see if it works?

[keen granite]

oh, that's a useful thing to know

[keen granite]

so what do you change, exactly?

[dense bolt]

yeah the whole making timerGo change to 2

so the update doesnt process

[keen granite]

ah, this looks familiar

[dense bolt]

wait i'll try it again just to be sure

nope still freezes

so i guess its the retaining the question thingy?

[keen granite]

so I wrote some code that freezes the game

if I execute that and then hit the pause button, it does show me the right stuff

[dense bolt]

yeah mine doesnt

[keen granite]

normally, when you break, you catch the game while it's just sitting around

waiting for the next frame

that explains what you're seeing, at least...although it is weird that nothing changes when the game is frozen

[dense bolt]

yeah

can we just focus on the checking the prev question? on how that does the infinite loop?

i think that is the cause of the infinite loop

[keen granite]

you could rule it out by removing the check

normally, I'd be trying a debugger after this kind of thing fails to find the problem, but I guess we're doing it backwards today 😛

[dense bolt]

alright i'll try it

[keen granite]

oh yeah, one other thing you might try with debugging

[dense bolt]

AHHAHAHA welp my code editor is not funcitoning properly

[keen granite]

if you right click on a line and add a breakpoint, then attach the debugger, it will auto-break when it hits that line

so, if I were using the debugger, I'd put a breakpoint on the function that checks for a duplicate

and see if it runs over and over

[dense bolt]

i see

btw

yeah it works perfectly without the checker of the prev question

so wdyt?

[keen granite]

okay, so that's the prime suspect

the question, though, is why it's getting stuck like this

it just stops you from getting the same one twice

even if there are only 5 choices, the odds of it getting stuck for a long time are insanely low

[dense bolt]

yes

should i add tostring ?

just like this

ansHandler = shapes[randomButtonShape].ToString();

does this help?

because the ansHandler is a string to begin with

[keen granite]

nope, that shouldn't be relevant

[dense bolt]

yeah i just came up with that loop

[keen granite]

if you want to catch it in action, maybe add a static int that counts how many times you've checked the answer

throw an exception if it gets over, say, 25

[dense bolt]

but if you have a better loop process that would be really helpful for my thesis

[keen granite]

and log the values at each step

you should see some kind of interesting pattern

like it picking the same string every time

[dense bolt]

yeah i tried that

like a string to check if what is being added to the string

and it still freezes before throwing back

[keen granite]

did you add a hard limit for the number of tries?

[dense bolt]

havent done that yet

should i try?

[keen granite]

like

public static int tries = 0;

[...]

void CheckAnswer(string str) {
  ++tries;
  Debug.Log(str);
  if (tries >= 25)
     throw new Exception();
}

[dense bolt]

i'll try that now

yeah it just freezes

i added a failsafe

but it still freezes

[keen granite]

show me what you wrote

[dense bolt]

        if(newAns == prevAnswer)
        {
            tries++;
            if (tries == 25)
            {
                checkertries.text = tries.ToString();
                ansIfGo = true;
                questionRandom();
            }
            checkertries.text = tries.ToString();
            ansIfGo = false;
            questionRandom();

        }

something like this

didnt add the throw

[keen granite]

i would just throw an exception

completely bail out

[dense bolt]

how do you add that again to a method?

[keen granite]

throw new Exception()

also, don't make this conditional

put this right at the start of the checker method

so that, no matter what, it can't run more than 25 times

[dense bolt]

like this?

void prevAnsCheck(string newAns) throws new Exception()

[keen granite]

ah, no, you don't add anything to the declaration

[dense bolt]

i think this is wrong

AHAHHAHHA

[keen granite]

this isn't Java

[dense bolt]

oh yeah

wait ill try again

ayo wtf?

[keen granite]

you've got a typo somewhere

enter safe mode, fix the errors, and it'll load

[dense bolt]

aight i'm in

i'll try this

wait

okay

the shit didnt change

this means the error occured

and i have the error on the code/unity

editor didnt freeze

[keen granite]

so the editor didn't freeze this time

that's good; we caught it

[dense bolt]

but i have an error

yes

so its the loop

[keen granite]

did you log the string it was trying each time?

[dense bolt]

yes

oh shit

i added the throw before the count

lmao

wait up

i'll run it again

alright now i thrown it after the counter

but its still 0

    void prevAnsCheck(string newAns)
    {
        
        if (newAns == prevAnswer)
        { 
            tries++;
            if (tries == 25)
            {
                checkertries.text = tries.ToString();
                throw new System.Exception();
                ansIfGo = true;
                questionRandom();
            }
            checkertries.text = tries.ToString();
            ansIfGo = false;
            questionRandom();

        }
        else
        {
            checkertries.text = tries.ToString();
            ansIfGo = true;
        }
    }

heres the code

[keen granite]

"it's still zero?"

[dense bolt]

yes

[keen granite]

i do not understand

what is still zero?

[dense bolt]

the tries counter

[keen granite]

ah, you added some text for it

[dense bolt]

yes

but its still 0

when i tried this code it just hangs

[dense bolt]

this

or freezes

[keen granite]

move this out to the very top of the function

            if (tries == 25)
            {
                checkertries.text = tries.ToString();
                throw new System.Exception();
            }

[dense bolt]

okay okay

[keen granite]

and increment tries up top, too

so that, no matter what, it does ++tries every time you call the function

[dense bolt]

okay i'll try it

wait

wtf

it doesnt do the freezing shit

wait

the loop is working

and it just loops for 1 time

i had a debug there to print the tries

oh

i removed the call

fuck

wait

there we go it freezes again

but the throw doesnt make it stop or resets

basically the part of tries == 25 is not being used

it just freezes

[keen granite]

this is making me think it's happening somewhere else

[dense bolt]

like where

changing the sprite?

[keen granite]

You might need to go back to the debugger and add a breakpoint somewhere in the answer picking function

and then step through it to see where it’s getting stuck

[dense bolt]

damn

[keen granite]

Adding a breakpoint should make it actually find your code

[dense bolt]

do you have a better way to do this looping thing for the question?

if its not a ahassle to you i'd be glad if you have a different method

[dense bolt]

i just fixed it

i removed the function

and just added the loop inside itself

something like this

    void questionRandom()
    {
        randomNumber = Random.Range(0, 3);
        randomButtonShape = Random.Range(0, maxRangeShape);
        ansHandler = shapes[randomButtonShape];
        if(ansHandler == prevAnswer)
        {
            Debug.Log(shapes[randomButtonShape]);
            questionRandom();
        }else if (ansHandler != prevAnswer)
        {
            Debug.Log(shapes[randomButtonShape]);
            questionNumber = questionNumber + 1;
            currentNum.text = questionNumber.ToString();
            randomBtns();
        }
    }

thank you

[keen granite]

ah, so it just calls itself now?

that is closer to how I'd do it, yeah
