}

witch just play a sound but when I call this function then all program frizing and when sound fish then program continue.

My code were I call fire function show bellow

LRESULT CALLBACK 
WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{   
    Circle bc; // Not needed in this demo, leave default.
    Vec2   p0(gClientCenter);
    Vec2   v0(0.0f, 0.0f);

    switch( msg )
    {   
    // Create application resources.
    case WM_CREATE:

        // Create the sprites
        gBackground = new Sprite(ghAppInst,
            IDB_BACKGROUND1024X768, IDB_BACKGROUND1024X768MASK, bc, p0, v0);

        gF15 = new Sprite(ghAppInst, IDB_F15, IDB_F15MASK,
            bc, p0, v0);

        p0.x = 100;
        p0.y = 100;
        gF18 = new Sprite(ghAppInst, IDB_F18, IDB_F18MASK,
            bc, p0, v0);
        gF18->mDirection = -1;

        p0.x = 600;
        p0.y = 100;
        gF117 = new Sprite(ghAppInst, IDB_F117, IDB_F117MASK,
            bc, p0, v0);
        //Start move
        gF117->mDirection = 1;

        p0.x = 0.0f;
        p0.y = 0.0f;
        gBullet = new Sprite(ghAppInst, IDB_BULLET, IDB_BULLETMASK,
            bc, p0, v0);

        //Enemy Bullet
        p0.x = 0.0f;
        p0.y = 0.0f;

Can anyone help me? Thank you

Answer 1

You can use OGRE libraries to develop games with c++

http://www.ogre3d.org/

It is free and Open Source. You can found an example game with ships. Have a look

Solution is here

void Sprite::fire()
{
    PlaySound("Sounds/azafire.wav", NULL, SND_ASYNC);
}

for me works perfect.
