我正在制作一个玩家必须避免随机坠落物体的游戏。我不知道如何实现暂停。我已经坚持了2天了!
我尝试使用 gotoAndPlay 等,但对象继续在后台运行。当我重新开始游戏时,它们仍在下落,看起来框架重置并加载了新的随机下落物体。
var steps:Number = 10;
var spriteX:Number = 280;
var spriteY:Number = 650;
var alienCounter=1;
var asteroidCounter=1;
var live:Number=3;
var depthLevel=3000;
var score:Number = 0;
var gamePaused;
dropTimer=setInterval(createAlien,2000);
drpTimer2=setInterval(createAsteroid,1000);
//---- functions ----
function checkKeys()
{
if (Key.isDown(Key.RIGHT))
{
spriteX += steps;
}
else if (Key.isDown(Key.LEFT))
{
spriteX -= steps;
}
}
function updateSpaceship()
{
ship._x = spriteX;
ship._y = spriteY;
}
function createAlien()
{
var curr_alien;
curr_alien=attachMovie("alien","alien"+alienCounter,depthLevel);
curr_alien._y=40;
curr_alien._x=Math.random()*510+20;
curr_alien._xscale=curr_alien._yscale=50;
curr_alien.speed=Math.random()*10+3;
alienCounter+=1;
depthLevel+=1;
curr_alien.onEnterFrame=alienMove;
}
function alienMove()
{
if(!gamePaused)
{
this._y+=this.speed;
if(this.hitTest(ship))
{
score += 1;
trace(score);
removeMovieClip(this);
}
}
}
function createAsteroid()
{
var curr_asteroid;
curr_asteroid=attachMovie("asteroid","asteroid"+asteroidCounter,depthLevel);
curr_asteroid._y=40;
curr_asteroid._x=Math.random()*510+20;
curr_asteroid._xscale=curr_asteroid._yscale=50;
curr_asteroid.speed=Math.random()*10+3;
asteroidCounter+=1;
depthLevel+=1;
curr_asteroid.onEnterFrame=asteroidMove;
}
function asteroidMove()
{
if(!gamePaused)
{
this._y+=this.speed;
if(this.hitTest(ship))
{
live -= 1;
trace(live);
removeMovieClip(this);
if(live<=0)
{
gotoAndPlay(5);
}
}
}
}
this.onEnterFrame = function()
{
checkKeys();
updateSpaceship();
if(Key.isDown(80))
{
if(!gamePaused)
{
gamePaused=true;
gotoAndPlay(4);
}
else
{
gamePaused=false;
gotoAndStop(3);
}
}
};
我决定改用钥匙,因为我在尝试使用按钮时找不到任何解决方案。暂停功能没有像我预期的那样工作,我需要多次输入键“p”来暂停它,但我不希望框架重置并在我恢复时加载更多随机对象。
