我在做一个游戏，角色必须拿到钥匙后通过大门 所以当他得到密钥的门想走开，我用

I'm making a game where the character has to pass through the gate after getting the key so when he gets the key the gate is suppose to go away, i used

if(character.hitTestObject(gate))
{character.visible = false;                   
youLose_text.visible = true; }

但是，当他得到的关键是：这是

if(character.hitTestObject(key))
{
   gate.visible = false; }

现在，当我穿过大门，我明明再次获得被杀 现在我该怎样删除previous如果通过函数的下一个IF函数？

NOW when i pass through the gate, i obviously get killed again now how do i remove the previous if function through the next if function?

推荐答案

如果门被认为实际上是走开，你应该彻底清除它，而不是只让看不见的...例如：

If the gate is supposed to actually "go away", you should completely remove it, not just make it invisible... e.g.:

if(character.hitTestObject(key)) {
    //don't forget to remove event listeners on the gate as well, if it had any
    removeChild(gate);
    gate = null;
} else if(gate != null) {
    if(character.hitTestObject(gate)) {
        character.visible = false;
        youLose_text.visible = true;
    }
}
