App gets stuck on WebGL
I've got a problem with Unity WebGL app. It is a multiplication quiz. When I enter wrong answer the whole webpage gets stuck, but when I enter the right answer - all is OK. How can I fix this wrong answer problem?
using UnityEngine; using System.Collections; using UnityEngine.UI;
public class Questions : MonoBehaviour {
public Text label;
public InputField input;
public Text rightText;
public Text wrongText;
public Button NextBtn;
private float multiplicand, multiplier, product;
// Use this for initialization
void Start () {
NextBtn.enabled = false;
GenerateNewQuestion();
input.Select(); //focus cursor to input field
Button btn = NextBtn.GetComponent<Button>();
btn.onClick.AddListener(TaskOnClick);
}
void TaskOnClick()
{
NextBtn.enabled = false;
GenerateNewQuestion();
input.enabled = true;
input.text = "";
rightText.text = "";
wrongText.text = "";
}
void GenerateNewQuestion()
{
multiplicand = Mathf.Round(Random.Range(0f, 10f));
multiplier = Mathf.Round(Random.Range(0f, 10f));
product = multiplicand * multiplier;
label.text = multiplicand + "*" + multiplier + "=";
}
// Update is called once per frame
void Update () {
if (Input.GetKeyDown(KeyCode.Return)) //enter key
{
CheckAnswer();
}
}
void CheckAnswer()
{
float userAnswer;
// if input is valid (is a number)
if(float.TryParse(input.text, out userAnswer))
{
// if the two values are the same
if (Mathf.Approximately(userAnswer, product))
{
rightText.text = ("Right! " + product);
input.enabled = false;
NextBtn.enabled = true;
}
else
{
wrongText.text = ("Wrong! " + product);
input.enabled = false;
NextBtn.enabled = true;
}
}
else
{
//input text is invalid, (e.g. text is blank or is not a number)
input.text = "";
}
}
}
