WebGL memory issue when using WWW to Download Images.
Hello guys,
The error happens when try to download a image from AWS server using WWW.
This topic may be recurrent, but I've not found a solution for this specific issue.
This is a quiz game with text and images questions, and i believe the error present where the code tries to download the image. Here a part of the code:
if(!string.IsNullOrEmpty(question.image_url))
{
loadingBarImg.fillAmount = 0;
percentageTxt.text = "0%";
//Debug.Log("Downloading image, from quesiton ID: "+question.id);
wwwQuestion = new WWW(question.image_url);
while (!wwwQuestion.isDone)
{
percentageTxt.text = Mathf.Round(wwwQuestion.progress*100)+"%";
loadingBarImg.fillAmount = wwwQuestion.progress;
}
yield return wwwQuestion;
question.questionImage = Utils.BytesToSprite(wwwQuestion.bytes);
}
Error presented on normal Build:
Error presented on development Build: (Sorry this one is in Portuguese (BR))
Any help or hint would be good. :)
This loop:
while (!wwwQuestion.isDone)
{
percentageTxt.text = Mathf.Round(wwwQuestion.progress*100)+"%";
loadingBarImg.fillAmount = wwwQuestion.progress;
}
will crash your app. Read this page, especially the section:
Do not block on WWW or WebRequest downloads
What should work is this:
while (!wwwQuestion.isDone)
{
percentageTxt.text = Mathf.Round(wwwQuestion.progress*100)+"%";
loadingBarImg.fillAmount = wwwQuestion.progress;
yield return null;
}
