嘿，伙计们，基本上我想创建多个关卡，我设置了如下所示的关卡，但由于某种原因，level_2的HittestObject没有启动。我不能精确地指出我做错了什么。第二级是启动的，但当我试图击中三个物体时，它只是直接穿过。
我有一个Goal_1和一个goal_2，我想与球员打。
我想为goal_1设置多个级别，为goal_2设置多个级别，等等
代码如下:

很抱歉这么久才给你回复。
这是一个如何设置关卡的例子…
gameLoop ()
我将在这里添加一个switch语句，让gamelloop知道每帧更新哪个关卡函数。switch语句类似于if…If else有条件，输入更少。开关语句的输出由nLevel与可能情况的比较决定。因此，当nLevel等于1时，level_1()函数被执行。通过添加nLevel，我们可以更新level_2()，等等。
private function gameLoop(e:Event):void
{
playerShoot();
playerControl();
playerStageBoundaries();
checkEndGameCondition();
checkPlayerOffScreen();
switch(nLevel) {
case 1:
level_1();
break;
case 2:
level_2();
break;
}
}
startNextLevel ()
此函数用于删除关卡函数中的重复代码，只需调用此函数，它将重置玩家位置并更新分数和关卡。
private function startNextLevel():void
{
nScore += 10;
updateHighScore();
nLevel++;
updatePlayerLevel();
updatePlayerLives();
player.x = (stage.stageWidth / 2) - 280;
player.y = (stage.stageHeight / 2);
}
水平功能/h3>
这些是你的关卡功能，而不是在每个关卡中添加玩家，只是重新使用玩家并重置它的位置。
private function level_1():void
{
if (player.hitTestObject(mGoal_1))
{
trace("Goal_1 Collision");
//Remove button for constant movement
btnShootPlayer = false;
mGoal_1.destroyGoal_1();
player.destroyPlayer();
startNextLevel();
}
else
{
checkEndGameCondition();
}
}
private function level_2():void
{
//Keep Text Scores initiated
if (player.hitTestObject(mGoal_2))
{
mGoal_2.destroyGoal_2();
player.destroyPlayer();
btnShootPlayer = false;
startNextLevel();
} else {
checkEndGameCondition();
}
}
