我创建了一个包含文本（a * b =）和输入字段（以获取用户答案）的预制件。并且我使用c＃脚本将此预制称为5次。我已经将a＆b分配给random.range（1,10），所以我可以获得5个不同的和。但就我而言，我所有5个总和的值都相同。
我尝试了foreach循环，它使随机数超出了给定范围，单击检查按钮，它甚至以红色显示了正确答案（不正确）。 这是我第一次通过脚本多次调用预制件。所以需要一些帮助来解决它。

答案 0 :(得分：0)
您应该在循环内获取随机值，否则您将获得相同的值。
foreach (TestModeQuestionUI _TestModeQuestionUIRefrence in testModeQuestionExampleList)
{
int a = UnityEngine.Random.Range(1, 10);
int b = UnityEngine.Random.Range(1, 10);
_TestModeQuestionUIRefrence.SetQuestionLabel(a, b);
}
您还应该将a和b保存在TestModeQuestionUI中，因为它们在实例之间是不同的。
public class TestModeQuestionUI : MonoBehaviour
{
private int a, b;
public void SetQuestionLabel(int a, int b)
{
this.a = a;
this.b = b;
valueA.text = a + " " + b + " = ";
}
}
答案 1 :(得分：0)
您有很多UI内容，但是如果我是您，并且如果我不想重复，那么我将创建一个单独的脚本来获取这样的随机值：
public class RandomIntegers {
private static List<int> myNumbersA = new List<int>();
private static List<int> myNumbersB = new List<int>();
public static void RandomValues(out int a,out int b)
{
if (myNumbersA.Count == 0)
{
for (int i = 0; i < 10; i++)
{
myNumbersA.Add(i + 1);
myNumbersB.Add(i + 1);
}
}
int indexA = Random.Range(0, myNumbersA.Count);
int indexB = Random.Range(0, myNumbersB.Count);
a = myNumbersA[indexA];
b = myNumbersB[indexB];
myNumbersA.RemoveAt(indexA);
myNumbersB.RemoveAt(indexB);
}
}
然后在您的ResetUI函数中，您可以使用
RandomIntegers.RandomValues(out a,out b);之所以以这种方式实现，是因为您的预制实例可以在实例化时访问它，并且由于它是静态的，因此对于a和b您将不会获得相同的随机结果。但是可以说，您可能获得6的{{1}}和a的{{1}}，但{{1}的8和{{1} {1}}都将以b结尾。
答案 2 :(得分：0)
如果您拥有一套价值，并且想要确保自己永远不会获得相同的价值，那么最好是将它们放在一个池中，并在使用它们时将其删除。
假设您要在10个不同的数字中进行5种可能的乘法运算。
Vector2[] vec;
private void GenerateOperations()
{
List<int> list = new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; // store all needed values
this.vec = new Vector2[5]; // your 5 results
for (int i = 0; i < vec.Length; i++)
{
int x = GetValue(list); // get x value
int y = GetValue(list); // get y value
vec[i] = new Vector2(x,y); // store in the index of the collection
Debug.Log(vec[i].ToString()); // print to check
}
}
private static int GetValue(List<int>list)
{
int rand = Random.Range(0, list.Count); // Get a random value from 0 to how many left in the list (last value is discarded so no out of bound exception)
int value = list[rand]; // Get the value at index
list.RemoveAt(rand); // remove that entry in the collection so it does not get picked again
return value; // return
}
现在，您将vec作为向量2的数组，它将给出操作的两个值。删除使用的值后，就不能再使用相同的值了。
您的vec集合可用于其他方法来创建UI。
