Help with 2d OpenGL top-down shooter.

Hi, I'm trying to make top-down shooter game with
C/SDL/OpenGL

http://w1.853.telia.com/~u85324201/game.zip

The problem is that when you shoot, the bullets don't come from the plane but from somewhere from the middle of the screen.

Here is the source:

Could somebody help?

I dont have time to compleatly read through your code, but are you updating the bullets position relative to where your plane is? I didnt see this occuring anywhere in your code but i only skimed it real fast beacuase im in class right now ;)

The bullet gets the planes position when you fire it.


void fireBullet()

{

int i = getBullet();

if (i != -1)
{
Bullet[i].Xpos = Xpos;

Bullet[i].Ypos = Ypos;

Bullet[i].Active = true;
}

}

are you positive you're updating xpos and ypos everytime the ship moves?

Xpos and Ypos are the planes position so
they are updated or the plane don't move :)

Like I said before the bullets gets the planes position once it's fired and then the bullets Ypos increases with 0.50 every frame.

This bug is really weird...
