Question

openList = Array([1,1], [2,3], [4,5]);
containss = function (input, arrayData, tellID) {
    for (i = 0; i < arrayData.length; i++) {
        if (arrayData[i] == input) {
            if (tellID) {
                return i;
            } else {
                return true;
            }
        }
    }
    return false;
}
trace(containss([2,3], openList, true));

This code returns false when openList contains 2,3. When I add trace(arrayData[i]), I get 1,1 2,3 4,5 and when I do trace(input) I get 2,3. What is wrong? Thanks

Answer 1

You are comparing 2 arrays using the equal operator:

arrayData[i]==input

This will always be false, no matter the contents of the arrays. The equal operator in your case tests if arraydata[i] is the same object with input not if 2 different objects (arrays) have the same content.
