以下は、Array と Vector の 2 つの 2D オブジェクトです。ご覧のとおり、両方に記載されている情報は同じです。私のゲームは Array オブジェクトを使用して問題なく動作しますが、Vector を使用すると次のエラーがスローされます。
[Fault] exception, information=RangeError: Error #1125: The index 10 is out of range 10.

Vector オブジェクトには、配列以外に実行時の範囲チェック (または固定長チェック) があることを読みました。これが問題でしょうか？

{
private var _softPlatformOpen:Boolean = true;
private var _elevatorOpen:Boolean = true;
public function TileCollisionController()
{}

{
var overlapX:Number;
var overlapY:Number;
//check top-left corner
if (platformMap[gameObject.top][gameObject.left] == platform)
{
overlapX = gameObject.xPos % maxTileSize;
overlapY = gameObject.yPos % maxTileSize;
if (overlapY >= overlapX)
{
if (gameObject.vy < 0 && platformMap[gameObject.bottom][gameObject.left] != platform)
{

gameObject.setY = gameObject.mapRow * maxTileSize;
gameObject.vy = 0;
