Thread: Need help on my Space Invaders Game

i can't compile it since i only have msvc.

But after a quick glance at the code i see this

Code:

for( int index = 0; index < XShot.length(); index ++ )
{
gotoxy(XShot[index],YShot[index]);
cout << " " ;
if( YShot[index] > 2 )
{
YShot[index] --;
}
else
{
XShot[index] = XShot[index-1]; <---     XShot[-1] when index=0 
YShot[index] = YShot[index-1]; <---         --""--
XShot.resize(XShot.length() - 1);
YShot.resize(YShot.length() - 1);
}
}

OH
thanks alot~
but now the bullets are flying everywhere?!!?
is there something wrong with the vectors?

this is what i did

Code:

else
             {
                   if( index > 1 )
                   {
                       XShot[index] = XShot[index-1];
                       YShot[index] = YShot[index-1];
                       XShot.resize(XShot.length() - 1);
                       YShot.resize(YShot.length() - 1);
                   }
             }

vector.erase(int spot)
vector.erase(int begin,int end)

They might be iretators instead of ints though there isn't much difference.
