timer already canceled

as u can see in the file, i am scheduling two tasks using TimerTask, and in the first line of the code in each task, u will see that i am returning if huntEnded is true, and while that works fine, the reason i am doing it like that is because, when i set the huntEnded to true and try to do timer.cancel() i just get a Timer already canceled, and i dont understand, why? i am not even trying to cancel while the task is being executed (sorry but i cant provide any error messages, i had this issue a while ago and replicating the thing will be painful but it basically just said timer already cancelled and pointed to the line where i have the timer.cancel())

How are you calling cancel?

MoonSouhaylOP•8mo ago

it was smth like this

public void setCaught() {
    timer.cancel();
    huntCaught = true;
    }

public void setCaught() {
    timer.cancel();
    huntCaught = true;
    }

if thats what ur asking about

dan1st•8mo ago

so you attempt to cancel the whole timer? not a specific task?

MoonSouhaylOP•8mo ago
