counter incrementing incorrectly
Hello. I am currently working on a quiz. I am playing a video and during the video at certain timestamps the questions are ot pop up in a quesitons canvas. There is another canvas called the Score canvas which displays th elive score as the user answers the questions. The questions are in multiple choice format. When the user clicks a button, the response value is sent to a function HandleResponse() and then the answer is cheked here. The score text is displayed as the score / the numebr of questions responded. So when the numQuestionsResponded variable is equal to 5, a button to view final score and exit video is displayed.
This worked fine until a couple of days back. I notice that the numQuestionsResponded value increments by 2 each time and the quiz ends at the 3rd question itself.
here is my code snippet
public void HandleAnswer(bool response) {
print("responded:" + response + "Correct answer" + nextQuestion.correct);
//check if the answer was correct
//hide the question canvas
questionCanvas.SetActive(false);
//increase the number of responded questions
numQuestionsResponded = numQuestionsResponded+1;
Debug.Log(numQuestionsResponded);
if (response == nextQuestion.correct)
{
totalCorrect++;
scoreText.text = "Correct!";
}
else
{
scoreText.text = "Wrong";
}
Debug.Log("Answered" + numQuestionsResponded);
scoreText.text += "\nScore:" + totalCorrect + "/" + numQuestionsResponded;
if (numQuestionsResponded == 5)
{
scoreText.text = "Final Score:" + totalCorrect + "/" + numQuestionsResponded;
PlayerPrefs.SetString("FullScore", scoreText.text);
Debug.Log(scoreText.text);
// PlayerPrefs.SetString("VideoTitle", Vidtitle.text);
btnexit.SetActive(true);
scoreText.text += "\nQuiz Over";
}
PrepareNext();
Earlier, the code to increment was numQuestionsResponded++. Just to make sure there is no problem in that, i changed it to numQuestionsResponded = numQuestionsResponded +1
What could be the reason for this?
using ++ ins$$anonymous$$d of writing out something = something + 1 does the same exact thing to an int.
your problem has to be co$$anonymous$$g from some other coding you didn't post.
either the code you posted is being called more often than you intend, or there is something else changing your variable.
look at where this code block is being called. maybe look for a mouse input that is registering every frame when it's held down. or any other code than might be run this more than you want.
then use your comilers search to ensure no other script lines are changing your varible!
sorry for the vague responce. we cant see the rest of your code
thanks for oyur response. please see my ful code in the reply below Also, i am noticing now that the totalCorrect counter is also incrementing in a werid way. Its sometimes displaying 4/6 whereas the total quesitons are on;ly 5 and the totalcorrect should be 2/3 at that timestamp of the video.
thanks for your reply. herwe is my complete code.
