Main game loop
Code:
void __fastcall TForm1::GameLoop(TObject*, bool &done)
{
int b,temp;
//checks if you've killed everything
if (dead_count == 21)
{
Application->MessageBoxA("You won!","Well done, you stopped the invasion", MB_OK);
Application->Terminate();
}
//Key presses are acted upon here
if (keys.right == true)
{
User->MoveRight(); //right key pressed, move right
}
if (keys.left == true)
{
User->MoveLeft(); //left key pressed, move left
}
if (keys.up == true)
{
User->MoveUp(); //up key pressed. move up
}
if (keys.down == true)
{
User->MoveDown(); // down key pressed. move down
}
// fires a regular laser shot
if (keys.laser == true)
{
//dynamicly allocates memory on the heap; User(the ship) is passed to the constructor
//so the x1 && y1 coords are the same as the users
laser.push_back(new User_Laser(User));
//keys.laser = false; //un-presses the space bar so we can't have insane firing speeds =)
}
// fires a regular missile shot
if (keys.missile == true)
{
//dynamicly allocates memory on the heap; User(the ship) is passed to the constructor
//so the x1 && y1 coords are the same as the users
missile.push_back(new User_missile(User));
keys.missile = false;//un-presses the control key so we can't have insane firing speeds =)
}
//deletes any unused lasers, then moves the rest
EraseObsoleteLasers(laser,Baddy);
EraseObsoleteMissiles(missile, Baddy);
//draws to the form. See the "Draw" file for further info
Draw(BackBuffer, User, Baddy, ClientRect, BackGround, laser, missile, Health, bdy_laser, bdyDraw, FirstMissile , FirstLaser);

And only one starts at 0. So i'm assuming that this isn't normal/right aka: whats causing my problems. I also tried testing for the laser.empty() property, and that didn't really work. Soo....the point to this ramble is, any idea why this is so whacked? Because when I go currentLaser-> , the auto complete thingy pops up, but not when I do, (*currentLaser)->.......soo......any help would be very much appreciated, because, I quite frankly, have no idea what i'm doing when it comes to vectors( and quite possibly, c++!
