Sending WM_PAINT anytime? (no MFC)

Lord Kixdemp

Hello, my fellow programmers! I'm trying to make a (simple) game using the Windows API. There's no animation, and probably won't be any time in the future, so the only time the game screen (which is stored in its own control) needs to be updated is right after user input. I got this working right by using InvalidateRect(hwnd, NULL, FALSE); after handling WM_KEYDOWN, but this causes a bit of flicker... I thought, "isn't there a vsync() style function?", but then, if the flicker is as noticeable as it is, then that means it's taking too much time to draw the game, which isn't good. I thought of using dirty rectangles (easy task since the game only consists of 32x32 tiles), but would that completely remove the flicker? Even on slower machines? Thanks in advance!

What do you want to do? do you want to send wm_paint?

Nevermind, I solved it, sorry for the noise... Turned out I was using the wrong flags on BitBlt. :wtf: It now works like a charm. [joke] And, Hamid, no offense, but do you live in these forums? You seem to be in like, every thread. :laugh: [/joke]

Do you really need to invalidate the entire client area? :)

I'll use the typical programmer's excuse to write crappy code: it was 3 AM and I didn't want to write code to check which parts needed updating. X| (Actually, it was 5 PM, but I hadn't slept at all that night... :laugh:)

Really you work too much for being a Lord. :-D

Yeah, day and night don't exist for me anymore...

while (Leo->IsAlive()
{
    Leo->WakeUp();
    Laptop->ResumefromHibernate();
    Laptop->m_aMessages = Email->Check();
    Laptop->Hibernate();
    Leo->Exercise(30);
    Laptop->ResumefromHibernate();

    Laptop->OpenEnvironment();
    while (Leo->m_pBody->m_pEyes[0]->CanStayOpen() &&
        Leo->m_pBody->m_pEyes[1]->CanStayOpen())
    {
        Leo->Code(Laptop);
    }

    Leo->GoToSleep();
}

Pretty sad, no? ;P

Is this time subtracted to coding? :-D

Yep. I spent my time coding, sleeping, and 30 minutes of exercise... if I'm not feeling lazy.;)

Not exactly.;)

Can you share the solution? It may help at least 4 or 5 users that asked about flickering in the last days.
