Direct INput problems

In answer to your first question, either will work. In answer to your second question:

lpdikeyboard->GetDeviceState(....); // blah while(!keys[VK_RETURN] & 0x80]) { lpdikeyboard->GetDeviceState(....); // blah }

Please state the nature of the debugging emergency.

MAYBE I should explain what i am doing...

in my main I have this:

InitDirectDraw();
InitDirectInput(hwnd);
Example();
WaitForKB();
MessageBox(hwnd, "You Pressed a key", "Event", 1);


My example shows a bitmap. the WaitForKB uses the code you gave me ( plus the variable declarations). I am basically thinking that if the messagebox shows, then the enter button was pressed.

I tried it like this:

while(!keyState[VK_RETURN] & 0x80)

and

while(keyState[VK_RETURN] & 0x80)

the message box came up both times when i was NOT touching the keyboard.... ACK what to do???

I had a problem similar to this just a few days ago. No matter what I did, it would still respond to the button being down, even if it wasnt. The solution I had was quite simple, really. Before you check the keyboard, or at some point in time, you have to call lpdiKeyboard->Acquire();. For me, I did this each time right before I checked the keyboard state with lpdiKeyboard->GetDeviceState(sizeof(diks),&diks); (I''m assuming this is DX7). Hopefully, this will work for you.

I think I am doing that, but it still doesnt enter the loop....



here is the code


void WaitForKB(void)
{

g_pKeyboard->Acquire();
unsigned char keystate[256];

g_pKeyboard->Acquire();
g_pKeyboard->GetDeviceState(256, &keystate); // blah

while(!keystate[DIK_RETURN] & 0x80 )
{
g_pKeyboard->Acquire();
g_pKeyboard->GetDeviceState(256, &keystate);
MessageBox(hwnd, "you have not pressed a button", "event", 1);
}

}

the message box here never comes up regardless of the keyboard

Are you supposed to use the windows procedure ( lresult callback wndProc(etc....)

with direct INput ???????????? I cant even get the GetAsyncKeyState(VK_LEFT) & 0x8000) to register a keypress.... Am I setting something up incorrectly???

I dont get it, is this some kind of impossible task??? It just doesnt work.. does anyone have a real working setup?????????? with CODE??

I am ripping my hair out. its enough to make one not want to make games >

Does any one have a small app that jsut runs in a loop until a person hits the enter key using direct input that they can show me the source code to?????

I am D E S P E R A T E please help

Stop the desperation!!

Seriously, just calm down and I HAVE done it (albeit in windows code)..my interpretation of the DirectInput stuff is like it''s a giant lookup table and/or state machine...it just sets itself according to the input given..

ALL you have to do in your main game loop is have a check for the key..you don''t need to lock your program into an infinite loop like you''ve done..

ie..main_loop is called during the idle times of the message queue (which I''ll post if you NEED it, but it''s everywhere)

TCHAR keystate[256];

main_loop() {

g_pKeyboard->Acquire();
g_pKeyboard->getDeviceState(sizeof(keystate), &keystate);

//if we hit escape then exit
if(g_pKeyboard->isHit(DIK_ESCAPE)){
PostMessage(g_hWnd, WM_CLOSE, 0, 0);
return(-1);
}

//otherwise do your code..
//display HUGE bitmap of Algore''s ego here

}

that should be enough to get the point..if you need further help, no problem I''ll help ya out (hopefully)
