[Solved] I have got an error while assigning value to int from an array [closed]

Question

Because num1 in a single int, not an array. Do you mean:

{
    int num1 = backData[num4, num3 + num2, 0];

    num1 += leftData[num4 + num, num3, 0];
}

However I suspect that that you are expecting num1 to be a reference to the array location you calculate in the first line. If that is the case just assign it directly:

backData[num4, num3 + num2, 0] += leftData[num4 + num, num3, 0];
