Console functions

Android_s · 2003-04-27T15:20:06

I am trying to get the base to a console Tetris close, or just a educational test =). But now my problem is this; I am trying to get the character to fall continuously from the top to bottom, but it stops at ReadConsoleInput();. I have understood that it works like a cin and therefore halts(i have the function in a continous loop), but is there anyway around this? The code is as following: void MoveBlock(BLOCK &Block) { INPUT_RECORD InputRecord; DWORD Events=0; ReadConsoleInput(hInput, &InputRecord, 1, &Events); if(InputRecord.EventType == KEY_EVENT && InputRecord.Event.KeyEvent.bKeyDown) { if(InputRecord.Event.KeyEvent.wVirtualKeyCode == VK_RIGHT) { DrawBlock(Block, ERASE); if(Block.Position.X >= 10) Block.Position.X = 10; else Block.Position.X++; DrawBlock(Block, DRAW); } else if(InputRecord.Event.KeyEvent.wVirtualKeyCode == VK_LEFT) { DrawBlock(Block, ERASE); if(Block.Position.X <= 0) Block.Position.X = 0; else Block.Position.X--; DrawBlock(Block, DRAW); } } Sleep(500); DrawBlock(Block, ERASE); Block.Position.Y++; DrawBlock(Block, DRAW); }

Ahh, great! It works much better now

Thank you very much!
Though...i do have one further question now of this new code. That "if(WAIT_TIMEOUT...bla bla", what exactly does it do? Why did it work with the ReadConsoleInput() now? Me feeling stupid... =/

Good question I know how to use it, just not how it works

My guess its some sort of multithreading, but I'm really clueless how it does it.

EDIT: That line tells the program to wait some number of milliseconds for imput if none is given then return.

Also why it works now I believe it was a void function before trying to return is what caused it to not work, making it a function that returned what it did then mowent to your move function worked. I'm somewhat still a newbie in programming as you.

-
if(WAIT_TIMEOUT == WaitForSingleObject(m_hInput, 20)) return;
-

With a call to WaitForSingleObject you instruct the operating system to wait for the given kernel object to become signaled. While waiting for the object the os can shedule another thread for processing time. When the object is signaled the function returns and the calling thread can be sheduled again. In this case the kernel object is a input handle, the object becomes signaled when there is any input pending.

Ahh, thanks Rob! Starting to become a bit clearer now

I think i have figured out exactly (or damn close) what it does. After looking at Jeff D''s code again and toasting my mind a couple of minutes things is getting clearer. Thanks once again
