Question

我需要建议。我正在做一个项目 - 一个简单的游戏。它将类似于＆＃34; Space Invaders＆＃34;。我只需要迎合船不能离开该地区（舞台）。功能，被称为＆＃34; RMimoXY＆＃34;不起作用。有人可以查看我在节目中缺少的内容吗？

提前感谢您的建议。

import flash.events.KeyboardEvent;
import flash.display.Sprite;
import flash.display.DisplayObject;
import flash.media.Sound;
import flash.display.Stage;

var let: Boolean = false;
var pozadi: Stage;
var vx:Number = 0;
var vy:Number = 0;

function mezernik(){
    var mySound: Sound = new laserFire(); 
    mySound.play();
    RMimoXY();
}

stage.addEventListener(KeyboardEvent.KEY_DOWN, klavesnice);

function klavesnice(e: KeyboardEvent){
    switch(e.keyCode){
        case Keyboard.LEFT: lod.x += -5; break;
        case Keyboard.RIGHT: lod.x += 5; break;
        case Keyboard.UP: lod.y += -5; break;
        case Keyboard.DOWN: lod.y += 5; break;
        case Keyboard.SPACE: mezernik(); break;
    }
}

function RMimoXY(){
    if (lod.x > stage.stageWidth ){ 
        lod.x =  0 - lod.width; 
    } 
    else if (lod.x < 0 - lod.width ){ 
        lod.x = stage.stageWidth; 
    } 
    if (lod.y > stage.stageHeight ){ 
        lod.y = 0 - lod.height; 
    } 
    else if (lod.y < 0 - lod.height ){ 
        lod.y = stage.stageHeight; 
    }
}

好像你只是在构造函数中调用RMimoXY。你应该在每次移动船只时调用它。因此，将其添加到keyhandler的末尾应该可以正常工作：

function klavesnice(e: KeyboardEvent){
    switch(e.keyCode){
        case Keyboard.LEFT: lod.x += -5; break;
        case Keyboard.RIGHT: lod.x += 5; break;
        case Keyboard.UP: lod.y += -5; break;
        case Keyboard.DOWN: lod.y += 5; break;
        case Keyboard.SPACE: mezernik(); break;
    }
    RMimoXY();
}
