我正在尝试使用矢量拍摄

我目前正在用c++编写一个带有direct X的游戏，目前有一个向量来存储绘制我所有的精灵。我无法让子弹在矢量中工作。子弹射出，但只有一颗在应该有50 的时候射出

//this vector also contains all other sprites i have like my player and my score and other sprites 
///Draw is a class
vector<Draw*> chap;
vector<Draw*>::iterator it;
Draw *bullet = NULL;
///initialization of stuff
for (int i = 0; i < gt; i++)
{
    bullet = new Draw[gt];
    //this sets the x position and y position and other properties 
    bullet[i].setDraw(blet,0,0,.1,.1,0,64,64,1,0,1,color,0,0,90,0,0,false);
    chap.push_back(&bullet[i]);
}
//end initialization
///game loop
for (int i = 0; i < bell; i++)
{
    for (it = chap.begin(); it != chap.end(); it++)
    {
        (*it)->testShoot(&bullet[i], ME);
        ME->playerMove();
        monster1->move();
    }
}
///end loop there is other stuff in loop but doesn't effect anything
/// what i'm using 
void Draw::testShoot(Draw *sprite, Draw *sprite1)
{
    if ((int)timeGetTime() < timer + 100)return;
    timer = timeGetTime();
    for (int i = 0; i < 50; i++)
    {
        if (Key_Down(DIK_SPACE))
        {
            if (!sprite[i].alive)
            {
                sprite[i].x = sprite1->x + sprite1->width / 4;
                sprite[i].y = sprite1->y + sprite1->height / 4;
                sprite[i].velx = 1;
                sprite[i].vely = 0;
                sprite[i].alive = true;
                break;
            }
        }
    }
}
